Cook a tender, flavorful turkey breast in a slow cooker without tying up the oven. Choose garlic-herb turkey with homemade gravy or a viral cranberry-and-onion version, with weight-by-weight timing guidance, exact quantities, safe thawing and ways to avoid overcooking.
Why make turkey breast in a slow cooker?
A slow cooker turkey breast is the sensible Thanksgiving solution when you want juicy slices for a smaller group without occupying the oven all afternoon. There is no need to roast a whole bird, manage a large pan or build a complicated brine. A boneless breast is easy to carve, and a skin-on breast can be browned briefly under the broiler after slow cooking.
There are two useful but different approaches. The garlic-herb version raises the turkey on onion and garlic, lets its own juices collect below and finishes with homemade gravy. The cranberry-onion version uses whole-berry cranberry sauce, onion soup mix and orange juice or cider to make a sweet-savory holiday sauce while it cooks.
The important thing is not the promised number of slow-cooker hours. Modern machines vary widely, breast shape matters, and turkey breast is lean. Use a meat thermometer and stop cooking when the thickest center reaches 165°F (74°C).
Serves: roughly 6, depending on portion size and bones
Prep: 15 minutes
Slow cook: estimated 5–6 hours for a 4–4½-lb breast on LOW; start checking sooner
Finish: 20-minute rest, optional 3–5-minute broil.
Boneless or bone-in turkey breast: what to buy
Boneless breasts, often held in butcher’s netting, suit a 4–6-person dinner and carve into neat slices. Bone-in breasts are usually larger and can be flavorful, but they require a roomy slow cooker and careful temperature checking in the thickest part, away from bone. Check the package for enhanced, self-basting, pre-brined or an added sodium solution. If so, reduce the rub salt and taste the gravy before seasoning.
A useful shopping estimate is roughly 10 ounces (280–300 g) raw boneless turkey breast per guest when you want generous portions and some leftovers; bone-in cuts need more total weight because bone is not edible. For a large bone-in breast, some holiday planners allow approximately 1¼ lb (560 g) per person, especially if leftovers matter.
Suggested LOW cooking windows—not guarantees
| Turkey breast weight | Cut | Possible LOW time | Start checking at |
|---|---|---|---|
| 1½–2 lb (0.7–1 kg) | Boneless | 3–4 hours | 2½–3 hours |
| 3 lb (1.35 kg) | Boneless roast, in netting | 3–4 hours | About 3 hours |
| 4–6 lb (1.8–2.7 kg) | Bone-in or boneless | About 5–6 hours | 4–4½ hours, possibly earlier in a hot cooker |
| 6–8 lb (2.7–3.6 kg) | Large bone-in breast | About 6–7 hours | 5–5½ hours |
| 9–10 lb (4.1–4.5 kg) | Extra-large breast/crown | Some recipes suggest 8–9 hours | 6½ hours or earlier; only if your appliance safely accommodates it |
These are planning ranges gathered in the supplied research, not USDA-certified cooking-time tables for your appliance. One reader’s 6-pound breast may be ready much sooner than another’s. Do not use a small slow cooker for a tightly packed 9–10-pound crown; follow the appliance manufacturer’s capacity guidance.

Garlic-Herb Slow Cooker Turkey Breast with Homemade Gravy
- Total Time: 5 hours 15 minutes
- Yield: 6–8 servings (depending on bone and portion size) 1x
Description
A tender slow-cooker turkey breast raised on onions, garlic and thyme, with pan juices turned into a simple homemade gravy and an optional broiled skin.
Ingredients
1 fully thawed turkey breast, 4–4 1/2 lb (about 2 kg), preferably skin-on and not pre-brined
1 large yellow or brown onion, halved crosswise
1 whole head garlic, sliced in half horizontally
5 sprigs fresh thyme or 2 teaspoons dried thyme
1 1/2 teaspoons garlic powder
1 1/2 teaspoons onion powder
1 teaspoon paprika
Up to 2 teaspoons salt for an unbrined turkey; much less if enhanced or pre-salted
About 1/2 teaspoon freshly ground black pepper
1 1/2–2 tablespoons olive oil
2 cups (about 500 ml) strained turkey cooking juices plus unsalted stock if needed, for gravy
4 tablespoons butter (about 50–55 g), for gravy
1/4 cup (about 30–35 g) all-purpose flour, for gravy
Fresh black pepper for gravy; salt only after tasting
Instructions
Fully thaw the turkey and check the packaging for enhanced, pre-brined or salted meat. Remove any gravy or giblet packets. Dry the meat using clean paper towels.
Put the onion halves, halved garlic head and thyme in the bottom of a suitably sized slow cooker. Set the turkey breast on top so it sits above accumulated juices. Do not add water for this herb-style version.
Mix garlic powder, onion powder, paprika, adjustable salt, black pepper and olive oil into a rub. Coat the top and sides of the turkey evenly.
Cover and cook on LOW for approximately 5–6 hours for a breast of this size, but begin probing the thick center earlier because slow cookers vary greatly.
Remove turkey as soon as the thickest central area reaches at least 165°F (74°C), avoiding contact with bone when taking the reading. Do not leave the finished turkey on WARM for an extended period.
Rest on a rimmed tray or board for about 20 minutes. If skin-on, optionally place beneath a preheated broiler for 3–5 minutes, approximately 12 inches (30 cm) below the heat, watching continuously.
Strain slow-cooker drippings, adding unsalted chicken stock to reach 2 cups. Melt the butter in a saucepan, whisk in flour and cook 1–2 minutes.
Gradually whisk in the strained juices and simmer until smooth and thickened. Taste the gravy before adding any salt. Slice the rested turkey across the grain and serve with gravy.
- Prep Time: 15 minutes
- Cook Time: 5 hours
Ingredients for the turkey
- One 4–4½-lb (about 2 kg) fully thawed turkey breast, preferably skin-on, not heavily pre-brined
- 1 large yellow or brown onion, halved crosswise (peeling optional, remove papery dirt)
- 1 whole garlic head, sliced in half horizontally
- 5 sprigs fresh thyme or 2 teaspoons dried thyme
- 1½ teaspoons garlic powder
- 1½ teaspoons onion powder
- 1 teaspoon paprika
- Up to 2 teaspoons salt if the turkey is unbrined; use much less for an enhanced or salted breast
- About ½ teaspoon freshly ground black pepper
- 1½–2 tablespoons olive oil
For the gravy
- 2 cups (about 500 ml) strained turkey cooking liquid, adding unsalted chicken stock if needed
- 4 tablespoons butter (about 50–55 g)
- ¼ cup all-purpose flour (about 30–35 g)
- Fresh pepper; salt only after tasting
Step-by-step slow cooker method
- Thaw and check the label. Make sure the turkey is fully thawed and suitable for the cooker. Remove any giblet or gravy packet from its cavity or packaging; use packaged gravy separately only if you wish. Pat the breast dry with clean paper towels.
- Build a natural rack. Put onion halves cut-side down and the two garlic-head halves in the bottom of the slow cooker. Nestle in thyme. The vegetables support the turkey above the accumulating liquid; for this herb-style recipe, do not add water to the crock initially.
- Season the surface. Mix garlic powder, onion powder, paprika, pepper, adjusted salt and olive oil into a paste. Rub the turkey on all accessible sides and, if skin-on, over the skin. Use the manufacturer’s instructions when handling a tied roast.
- Cook on LOW. Set the breast over the onion and garlic. Cover. For a 4–4½-lb breast, plan around 5–6 hours, but begin checking the thickest part earlier. Avoid repeatedly lifting the lid: every opening slows cooking.
- Use the thermometer. Test in at least one thick central location, avoiding bone or the edge. When the turkey reaches 165°F (74°C), carefully move it to a rimmed board or oven-safe tray. Do not leave it sitting in the cooker on WARM while finishing other dishes.
- Rest and crisp the skin. Tent loosely and rest about 20 minutes. If it has skin, place it under a preheated broiler for around 3–5 minutes, keeping the meat approximately 12 inches (30 cm) below the heat and watching continuously. Broiling is optional; avoid burning the rub.
- Make the gravy. Strain the slow-cooker juices. Add unsalted stock to make 2 cups if necessary. Melt butter in a saucepan, whisk in flour and cook 1–2 minutes. Gradually add the liquid, starting with a splash to avoid lumps. Simmer gently until thickened; taste before adding salt.
- Slice. Remove any netting once the roast has rested, then carve across the grain into slices. Spoon warm gravy over each serving or serve it in a boat.
Herb butter option
For a garlic-butter finish, combine softened butter with minced garlic, thyme, sage, rosemary and parsley. Carefully loosen the skin and place approximately two-thirds of the herb butter under it; spread the rest over the surface. This adds richness but also additional calories and fat compared with the olive-oil rub, so do not reuse a nutrition estimate from the lower-fat version.
Why no added water? A whole breast releases juices as it cooks. Elevating it on aromatics keeps the bottom from poaching directly in a deep pool and leaves savory drippings for gravy. This differs from a cranberry recipe that intentionally uses added sauce and juice.

Cranberry Onion Slow Cooker Turkey Breast
- Total Time: 3 hours 15 minutes
- Yield: 4–6 servings 1x
Description
A sweet-savory boneless turkey roast with whole-berry cranberry sauce, dry onion soup mix and orange juice cooked in a slow cooker.
Ingredients
1 fully thawed boneless turkey breast roast, about 3 lb (1.35 kg), with its manufacturer’s netting intact while cooking
1 can (14 oz / 400 g) whole-berry cranberry sauce
1 envelope (1 oz / 28 g) dry onion soup mix
1/2 cup (120 ml) orange juice or apple cider
1 teaspoon paprika
1 teaspoon poultry seasoning
1 teaspoon garlic powder
2 teaspoons brown sugar, optional if cranberry sauce is already sweet
Optional: 1 tablespoon cornstarch mixed with 2 tablespoons cold water, to thicken sauce
Instructions
Check that the boneless turkey roast is completely thawed. Remove any packaged gravy insert, pat the roast dry and leave the netting in place if the manufacturer instructs this.
Grease the slow cooker lightly and set the turkey in the center.
In a separate bowl combine whole-berry cranberry sauce, onion soup mix, orange juice or cider, paprika, poultry seasoning, garlic powder and optional brown sugar. Taste the sauce before it touches raw meat if adjusting sweetness.
Pour cranberry mixture over the turkey, cover and cook on LOW for roughly 3–5 hours. Begin checking early in a fast or modern slow cooker.
When a thermometer in the thickest center reaches at least 165°F (74°C), remove turkey. Rest about 20 minutes before removing netting and carving.
If you want a thicker sauce, transfer the slow-cooker liquid to a saucepan, bring to a simmer, stir in cornstarch mixed with cold water and cook until thickened. Serve over the sliced turkey.
- Prep Time: 15 minutes
- Cook Time: 3 hours
This version is especially practical with a 3-lb (1.35-kg) boneless roast. The sauce is tart, sweet, savory and ready for holiday serving; the meat stays in its netting while cooking, so it holds its shape.
Prep: 10–15 minutes
LOW cook: roughly 3–5 hours, stopping at 165°F.
Exact ingredients
- 1 fully thawed, 3-lb boneless turkey breast roast; leave the manufacturer’s netting on during cooking
- One 14-ounce (400 g) can whole-berry cranberry sauce
- One 1-ounce (28 g) envelope dry onion soup mix
- ½ cup (120 ml) orange juice or apple cider
- 1 teaspoon paprika
- 1 teaspoon poultry seasoning
- 1 teaspoon garlic powder
- 2 teaspoons brown sugar (optional, especially if the cranberry sauce is already sweet)
- Optional sauce thickener: 1 tablespoon cornstarch mixed with 2 tablespoons cold water
Directions
- Remove the gravy packet, if present. Pat the thawed, netted turkey dry and set it in a lightly greased slow cooker.
- In a bowl, stir the whole-berry cranberry sauce with the onion soup mix, orange juice or cider, paprika, poultry seasoning, garlic powder and optional brown sugar. Taste a separate spoonful of the sauce mixture for sweetness, but do not taste it after contact with raw turkey.
- Pour the sauce over the roast, cover and cook on LOW for approximately 3–5 hours. Start checking before the expected finish, particularly in a modern cooker.
- When the thickest center reaches 165°F (74°C), transfer the roast to a board and rest for approximately 20 minutes. Remove the netting, slice and keep warm.
- For a thicker glaze, pour the cooker liquid into a saucepan. Bring to a simmer, whisk in the cornstarch slurry and cook until it thickens. Spoon over the turkey.
Sodium warning: Dry onion soup mix can be very salty, and some pre-brined roasts contain additional sodium. Check labels and avoid automatically adding more salt. Cranberry sauce and orange juice contribute real carbohydrates; do not represent this as a four-gram-carbohydrate meal. The supplied research reports roughly 365 calories, 50 g protein and 34 g carbohydrate per serving for a particular published version, but portions and brands change those estimates.
Low-effort substitution: Use ½ cup apple cider in place of orange juice for a warmer apple flavor; a splash of orange juice can brighten the finish.
How to thaw turkey breast safely
For refrigerator thawing at 40°F (4°C) or colder, allow roughly 24 hours per 4–5 lb of turkey; smaller roasts may thaw sooner, but leave margin in your holiday plan. Keep wrapped turkey on a tray so drips cannot contaminate other food.
Cold-water thawing takes approximately 30 minutes per pound when the turkey stays in leakproof packaging, submerged in cold water that is changed every 30 minutes. Cook immediately after cold-water thawing.
Do not put a frozen or partly frozen breast directly into a slow cooker. USDA food-safety guidance recommends thawing poultry first so it does not spend too long warming through unsafe temperatures. Microwave thawing may be used when the package and microwave are suitable, but cook the turkey immediately afterward; the refrigerator method gives the most predictable results for a large roast.
Turkey breast troubleshooting
| Problem | Why it happens | What helps |
|---|---|---|
| Dry, shredding or rubbery breast | Overshot 165°F or spent too long on WARM | Monitor earlier; remove promptly when done; add gravy to sliced servings |
| Pale, soft skin | Slow cookers trap moisture and do not brown | Use a short, watched broiler finish after cooking |
| Gravy is too salty | Pre-brined turkey or onion soup packet | Use unsalted stock, taste first, add acid or unsalted cooking liquid |
| Gravy is lumpy | All the broth added at once to flour | Whisk in small portions, then gradually add more |
| Very little drippings | Small breast or different cooker size | Top up with unsalted chicken stock to reach 2 cups |
| Turkeys cook at different rates | Differences in thickness, bone and cooker heat | Thermometer determines doneness; time charts are only rough guides |
A simple Thanksgiving serving plan
Start the meal with our charcuterie dip recipe, then serve the turkey with your favorite sides. For leftover ideas beyond sandwiches, try our high-protein low-calorie meal ideas, adjusting quantities and gravy to fit your meal.
Let the slow cooker handle the turkey while your oven roasts vegetables and heats bread. The garlic-herb turkey pairs with green bean casserole, cranberry relish, mashed potatoes and a light salad. The cranberry-onion version already has a sweet sauce, so consider savory sides and avoid adding another overly sweet glaze.
Storage: Transfer cooked turkey and gravy to shallow covered containers and refrigerate within two hours at 40°F (4°C) or colder. Use cooked turkey within 3–4 days or freeze it. Reheat leftovers to 165°F (74°C). For tender reheating, warm sliced meat covered with a little gravy rather than exposing it to dry heat.
For a holiday meal, food safety matters more than holding a rigid schedule. If the turkey finishes early, refrigerate it safely rather than leaving it for hours in an unmonitored cooker.
FAQS
How long does a 3-pound boneless turkey breast take in the slow cooker?
Many recipes estimate 3–4 hours on LOW, but a hot cooker or differently shaped roast may cook faster or slower. Begin checking near the third hour and remove the breast when it reaches 165°F (74°C).
Do I need to add water to slow cooker turkey breast?
Not for the garlic-herb recipe here: onion and garlic support the breast while it releases its own juices. The cranberry version intentionally adds sauce and juice; these are different methods.
Should I cook turkey breast on HIGH or LOW?
LOW is generally more forgiving for a lean breast and is the setting used in both recipes here. The safe endpoint is still 165°F, regardless of setting.
Can I cook frozen turkey breast in a slow cooker?
No. USDA guidance recommends thawing poultry before slow cooking to avoid a prolonged period at unsafe temperatures.
How do I get crispy turkey skin from a slow cooker?
The skin stays soft while slow cooking. Once the breast has reached 165°F, brown it briefly under a closely watched broiler, preferably 3–5 minutes.
Should I remove turkey netting before slow cooking?
For a manufactured boneless roast held in netting, keep the netting during cooking unless the package states otherwise, then remove after resting and before slicing.
What is the safe internal temperature for turkey breast?
165°F (74°C) in the thickest part, measured with a food thermometer. Avoid placing the probe against the bone.
Can I use leftover cooking liquid for gravy?
Yes. Strain the drippings, top up with unsalted broth if necessary and thicken with a butter-and-flour roux or cornstarch. Taste before seasoning.
