The safest way to slow cook turkey is to use a thawed turkey breast, not a whole turkey. Place the breast in a 6-quart slow cooker with broth and seasonings, cook until the thickest part reaches 165°F, then rest it before slicing. A 4- to 6-pound turkey breast usually takes about 6 to 8 hours on LOW, but a food thermometer must decide when it is done.
A whole turkey is too large for most slow cookers. Its cavity can also heat too slowly, which raises the risk of foodborne illness. For guidance in U.S. kitchens, follow the USDA advice for cooking turkey and use a thermometer rather than time alone.
What You Need to Slow Cook Turkey
You need a thawed turkey breast, a slow cooker large enough to hold it, and a food thermometer. Bone-in and boneless turkey breasts both work.
Ingredients
For a 4- to 6-pound turkey breast, gather:
- 1 thawed turkey breast
- 1 cup low-sodium chicken or turkey broth
- 2 tablespoons olive oil or softened butter
- 1 teaspoon kosher salt, or less for a pre-seasoned turkey
- 1 teaspoon dried sage
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- 1 teaspoon garlic powder
- ½ teaspoon black pepper
- 1 small onion, sliced
- 2 celery stalks, cut into large pieces
- 2 carrots, cut into large pieces
- 2 garlic cloves, crushed
- 1 lemon, cut in half
Check the label before adding salt. Some turkey breasts contain a salt solution or are sold as “pre-basted.” Extra salt can make them too salty.
Equipment
Use:
- A 6-quart slow cooker for most 4- to 6-pound turkey breasts
- An instant-read or leave-in food thermometer
- Tongs or a wide spatula
- A cutting board with a rim or a large platter
- Foil for resting
The turkey should fit with the lid fully closed. Do not force a large breast into a small cooker.
How to Prepare the Turkey
Thaw the turkey completely in the refrigerator before slow cooking it. Keep the turkey in its package while it thaws. The USDA recommends allowing about 24 hours for every 4 to 5 pounds of turkey in a refrigerator set at 40°F or below.
Do not thaw turkey on the counter. Do not put a frozen turkey breast into a slow cooker. A slow cooker heats food gradually, so frozen poultry may remain in the danger zone too long.
Remove the turkey from its package and take out the gravy packet or neck, if included. Pat the skin dry with paper towels. Do not rinse the turkey. Washing raw poultry can spread germs around the sink and nearby surfaces.
If the turkey breast has a large amount of loose skin or fat, trim only what you need. The skin helps protect the meat during cooking, even though it will not become crisp in a covered slow cooker.
Step-by-Step: How to Slow Cook a Turkey Breast
Follow these steps for a tender slow cooker turkey breast with simple pan juices.
1. Add the vegetables and broth
Place the onion, celery, carrots, and garlic in the bottom of the slow cooker. Pour in the broth.
The vegetables form a low rack for the turkey. They also add flavor to the cooking liquid. The turkey does not need to be covered with liquid.
2. Season the turkey
Mix the salt, sage, thyme, rosemary, garlic powder, and pepper in a small bowl. Rub the turkey with olive oil or softened butter, then coat it with the seasoning mix.
For a bone-in turkey breast, rub some seasoning under the skin if you can loosen it without tearing it. This adds flavor to the meat. Avoid piercing the breast more than needed.
3. Place the turkey in the slow cooker
Set the turkey breast on top of the vegetables, skin side up. Make sure it is not wedged tightly against the lid.
Put the lid on the cooker. Keep it closed during cooking. Each time you lift the lid, heat escapes and the cooking time may increase.
4. Cook on LOW
Cook the turkey on LOW until the thickest part reaches 165°F.
Use these times as starting estimates:
| Turkey breast | Slow cooker setting | Approximate time |
|---|---|---|
| 2½ to 4 pounds, boneless | LOW | 4 to 6 hours |
| 4 to 6 pounds, bone-in | LOW | 6 to 8 hours |
| 6 to 8 pounds, bone-in | LOW | 7 to 9 hours |
These are not guarantees. Slow cookers vary, and the shape of the turkey matters. A wide, flat breast can cook faster than a thick one of the same weight.
Begin checking the temperature during the shorter part of the time range. Insert the thermometer into the thickest part of the breast. Avoid touching the bone, because the bone can give a false reading.
5. Confirm that it is done
The turkey is ready when the thickest part reaches 165°F. Check more than one spot if the breast has an uneven shape.
The meat should look opaque, and the juices may run clear. These signs can support your check, but they do not replace a thermometer.
6. Rest and carve
Move the turkey to a cutting board. Cover it loosely with foil and let it rest for 15 to 20 minutes.
Resting gives the juices time to settle. It also makes the turkey easier to slice. Cut across the grain into even slices.
Do not leave cooked turkey at room temperature for more than 2 hours. If the room is above 90°F, refrigerate it within 1 hour.
How Long Does Turkey Take in a Slow Cooker?
A turkey breast usually takes 4 to 8 hours on LOW, depending on its weight, shape, bone structure, and the slow cooker itself.
Time is only a guide. The safe endpoint is 165°F in the thickest part. A large bone-in breast may take longer than a smaller boneless breast because the bone and thicker shape slow heat movement.
Do not rely on the slow cooker’s automatic switch to “WARM” as a cooking method. The turkey should reach 165°F before it is held on WARM. If you need to delay the meal, refrigerate the cooked turkey within the safe time limit rather than leaving it at room temperature.
Should you cook turkey on HIGH?
LOW is usually the better setting for texture. It gives the meat more time to soften and may help prevent a dry outer layer.
HIGH can work for smaller turkey breasts if the cooker manual and recipe allow it, but the cooking time is less predictable. Start checking early and remove the turkey as soon as the center reaches 165°F.
How to Keep Slow Cooker Turkey Moist
Use enough liquid to create steam, but do not drown the turkey. About 1 cup of broth is enough for most 4- to 6-quart cookers.
Other useful steps include:
- Choose a bone-in breast for more flavor and protection from drying.
- Rub the meat with butter or oil before seasoning.
- Keep the lid closed.
- Avoid cooking a very small breast in a very large slow cooker.
- Do not leave the turkey on LOW long after it reaches 165°F.
- Slice only what you plan to serve right away.
Slow cooking can produce tender meat, but it will not produce crisp skin. The moist, closed environment softens the skin.
If you want browned skin, move the cooked turkey to a baking sheet and place it under a broiler for a few minutes. Watch it closely. The broiler can burn the skin quickly. Use a broiler-safe dish and follow the instructions for your oven.
How to Make Gravy From the Slow Cooker Juices
The liquid in the slow cooker can make a quick gravy. First, strain it to remove the vegetables and herbs. Skim off some fat if the liquid looks greasy.
For about 2 cups of gravy:
- Melt 2 tablespoons of butter in a saucepan.
- Whisk in 2 tablespoons of flour.
- Cook for about 1 minute.
- Slowly whisk in 2 cups of strained turkey broth.
- Simmer until thickened.
- Add pepper and salt only after tasting.
The broth may already contain salt, especially if the turkey was injected with a seasoning solution. Taste before adding more.
For gluten-free gravy, use a gluten-free flour blend or a cornstarch slurry. To make a slurry, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water. Whisk it into simmering broth and cook until the gravy thickens.
Can You Slow Cook a Whole Turkey?
A whole turkey should not be cooked in a standard slow cooker. Most slow cookers are not large or deep enough to hold a whole bird safely. The cavity and center may also heat too slowly.
Use one of these options instead:
- Cook a turkey breast in the slow cooker.
- Roast the whole turkey in a conventional oven.
- Use another cooking method specifically designed for a whole turkey.
Do not put stuffing inside a turkey breast or whole bird being cooked in a slow cooker. Stuffing can stay at an unsafe temperature while the turkey cooks. Prepare stuffing separately.
Food Safety Rules for Slow Cooker Turkey
Safe handling matters before, during, and after cooking.
Before cooking
- Thaw turkey in the refrigerator.
- Wash hands after handling raw poultry.
- Clean cutting boards and counters with hot, soapy water.
- Keep raw turkey away from ready-to-eat foods.
- Do not rinse the turkey.
During cooking
- Keep the slow cooker covered.
- Do not cook a frozen turkey breast.
- Do not overfill the slow cooker.
- Check the thickest part with a food thermometer.
- Cook until the turkey reaches 165°F.
The USDA identifies 40°F to 140°F as the temperature range in which bacteria can grow quickly. Move cooked turkey to the refrigerator within the recommended time limit.
After cooking
Store turkey in shallow containers so it cools quickly. Refrigerate leftovers at 40°F or below and use them within 3 to 4 days, according to [USDA food safety guidance].
You can freeze cooked turkey for longer storage. Reheat leftovers to 165°F. Add broth when reheating sliced turkey to help prevent dryness.
Common Problems and Fixes
The turkey is still below 165°F
Keep the lid closed and continue cooking on LOW. Check the temperature again in 30 to 45 minutes.
If the slow cooker is not heating properly, move the turkey to a covered oven-safe dish and finish it in an oven set to at least 325°F. Check the turkey with a thermometer before serving.
The turkey is dry
Dry turkey usually comes from overcooking, a small breast in a large cooker, or holding the meat on WARM for too long.
Slice the turkey and serve it with warm broth or gravy. For the next batch, check the temperature sooner and remove the breast as soon as it reaches 165°F.
The skin is pale or soft
This is normal in a slow cooker. The lid traps moisture, so the skin will not roast.
For firmer skin, place the cooked turkey under a broiler for a short time. Pat the skin dry first, brush it with oil, and watch it closely.
The turkey will not fit
Do not press the lid down or run the cooker with the lid partly open. Use a smaller turkey breast, cut the breast into large pieces if appropriate, or choose an oven method.
The slow cooker is too full
Food should not be packed tightly around the turkey. Overfilling can slow heating and lead to uneven cooking. Follow the capacity guidance in your slow cooker manual.
Can You Add Potatoes or Other Vegetables?
Yes. Add firm vegetables such as carrots, onions, celery, or small potatoes beneath the turkey. Cut them into similar-size pieces so they cook at a similar rate.
Do not use vegetables as proof that the turkey is done. Vegetables may become soft before the turkey reaches 165°F.
Green beans, peas, and other delicate vegetables are better added near the end or cooked separately. Long cooking can make them dull and mushy.
Key Takeaways
- Use a thawed turkey breast, not a whole turkey.
- Cook on LOW until the thickest part reaches 165°F.
- A 4- to 6-pound turkey breast often takes 6 to 8 hours, but times vary.
- Keep the lid closed while the turkey cooks.
- Rest the turkey for 15 to 20 minutes before slicing.
- Refrigerate leftovers within 2 hours and use them within 3 to 4 days.
FAQs: How To Slow Cook A Turkey In A Slow Cooker
Can I put a frozen turkey breast in a slow cooker?
No. Thaw the turkey breast in the refrigerator first. A frozen breast may spend too long at an unsafe temperature while the slow cooker heats it.
Do I need to add water to the slow cooker?
Add about 1 cup of broth or water for a typical 4- to 6-pound turkey breast. The turkey does not need to be submerged. Broth adds more flavor than plain water.
Should I cook turkey breast on LOW or HIGH?
LOW is the preferred setting for a tender result. HIGH may work for a small breast, but start checking the temperature early because cooking times vary by cooker.
Can I put stuffing inside the turkey breast?
No. Cook stuffing separately. Stuffing inside poultry can heat too slowly in a slow cooker.
How do I know when slow cooker turkey is done?
Check the thickest part with a food thermometer. The turkey is safe to serve when it reaches 165°F. Do not rely only on color, texture, or the cooking time.
Can I make turkey gravy in the slow cooker?
Yes. Strain the cooking liquid, then thicken it in a saucepan with a butter-and-flour roux or a cornstarch slurry. Taste before adding salt.
Conclusion
Slow cooker turkey works best when you use a thawed turkey breast and let temperature, not the clock, determine when it is done. Add broth and herbs, cook the breast on LOW, check for 165°F, and rest it before slicing. This method gives you tender turkey and flavorful juices without needing to roast a whole bird.
