A turkey roast cooks well in a slow cooker when you use a thawed roast, keep the lid closed, and check the meat with a food thermometer. For a 2- to 3-pound boneless turkey roast, cook on LOW for about 4 to 6 hours, or until the thickest part reaches 165°F, the safe minimum temperature for turkey set by the USDA.
This guide is written for home cooks in the United States. It uses Fahrenheit, U.S. food-safety guidance, and the turkey roasts commonly sold in American grocery stores.
What You Need
You need a few basic items to cook a turkey roast in a slow cooker:
- A thawed turkey roast, usually 2 to 3 pounds
- A 4- to 6-quart slow cooker
- 1 cup of low-sodium chicken or turkey broth
- 1 tablespoon olive oil or melted butter
- Salt and black pepper
- Dried herbs, such as thyme, sage, rosemary, or poultry seasoning
- Optional vegetables, such as onion, carrot, celery, or garlic
- An instant-read food thermometer
- Aluminum foil for resting the roast
Check the package before cooking. Some turkey roasts come tied in oven-safe netting. Others contain a gravy packet or seasoning mix. Remove plastic wrapping and any gravy packet before cooking. Keep oven-safe netting on during cooking if the package instructions allow it. Remove the netting before slicing.
A turkey breast roast is usually lean and mild. A boneless roast may cook faster than a bone-in roast of the same weight. The shape also matters. A thick, compact roast may need more time than a long, narrow roast.
How to Cook a Turkey Roast in a Slow Cooker
Follow these steps for tender turkey with simple pan juices.
1. Thaw the turkey safely
Thaw the turkey roast in the refrigerator before placing it in the slow cooker. Set the wrapped roast on a tray to catch leaks.
A small roast may thaw in the refrigerator in about 1 to 2 days. Larger roasts can take longer. Do not thaw turkey on the kitchen counter.
Do not put a frozen turkey roast in a slow cooker. The meat may remain in the food-safety danger zone for too long while the center warms.
2. Season the roast
Pat the turkey dry with paper towels. Rub the outside with olive oil or melted butter.
Season all sides with:
- 1 to 1½ teaspoons kosher salt, or less if the roast is pre-seasoned
- ½ teaspoon black pepper
- 1 teaspoon dried poultry seasoning
- Optional dried sage, thyme, rosemary, paprika, onion powder, or garlic powder
Read the label first. Some turkey roasts contain a salt solution. Heavy seasoning can make them too salty.
3. Add vegetables and broth
Place chopped onion, carrot, celery, or garlic in the bottom of the slow cooker if you want extra flavor. Set the turkey roast on top.
Pour about 1 cup of broth around the roast. The liquid should cover the bottom of the cooker, but it does not need to cover the turkey.
The broth creates steam and gives you a flavorful liquid for gravy. It does not turn the turkey into boiled meat unless you add too much liquid.
4. Cook on low
cover the slow cooker and cook on LOW for about 4 to 6 hours for a 2- to 3-pound roast.
Cooking time varies by:
- Roast weight
- Bone-in or boneless design
- Roast shape
- Slow cooker size
- Appliance temperature
- Starting temperature of the meat
Keep the lid closed during cooking. Each time you lift the lid, heat escapes and the cooking time increases.
5. Check the internal temperature
Begin checking the turkey near the early end of the time range. Insert the thermometer into the thickest part of the roast. Avoid touching bone, if the roast contains one.
The turkey is ready when it reaches 165°F. Check more than one spot if the roast is uneven in shape.
Color is not a safe way to judge doneness. Turkey may look pale and still be safe, or look browned before the center reaches a safe temperature.
6. Rest and slice
Move the cooked turkey to a cutting board. Cover it loosely with foil and let it rest for about 15 minutes.
Resting gives the juices time to settle. It also makes the roast easier to slice.
Remove any netting. Slice across the grain into thin, even pieces. Spoon the cooking juices over the turkey before serving.
Slow Cooker Turkey Roast Cooking Times
Cooking times are estimates, not guarantees. The thermometer decides when the roast is done.
| Turkey roast | Slow cooker setting | Approximate time | Safe final temperature |
|---|---|---|---|
| 1½ to 2 pounds, boneless | LOW | 3½ to 5 hours | 165°F |
| 2 to 3 pounds, boneless | LOW | 4 to 6 hours | 165°F |
| 3 to 4 pounds, boneless | LOW | 5 to 7 hours | 165°F |
| 3 to 5 pounds, bone-in | LOW | 5 to 8 hours | 165°F |
These ranges assume a thawed roast in a covered slow cooker. A slow cooker set to HIGH may finish sooner, but LOW often gives you a more forgiving cooking window.
Avoid using time alone. Slow cookers differ in heat output, and turkey can become dry if it stays in the cooker long after reaching 165°F.
If the turkey reaches 165°F early, remove it from the slow cooker. Do not leave it on the WARM setting for several hours unless you are monitoring the food and following safe holding practices.
How to Keep Turkey Roast Moist
The best way to keep turkey moist is to avoid overcooking it. Turkey breast contains little fat, so it can dry out when heated well beyond 165°F.
Use these methods:
- Cook the turkey on LOW when possible.
- Add about 1 cup of broth to the cooker.
- Keep the lid closed.
- Check the temperature early.
- Let the roast rest before slicing.
- Slice only what you plan to serve right away.
- Store leftovers with some broth or gravy.
You can also place a few small pieces of butter under the netting or on top of the roast. This adds flavor, but it cannot prevent dryness caused by overcooking.
A slow cooker will not brown the outside of the turkey. If you want a browned surface, remove the cooked roast from the slow cooker and place it under a broiler for a short time. Watch it closely because the surface can burn quickly.
Do not broil a turkey roast while it is still in a slow cooker insert unless the insert is specifically rated for broiler use. Many ceramic and stoneware inserts can crack under direct broiler heat.
How to Make Gravy From the Slow Cooker Juices
The liquid left in the slow cooker can make a quick gravy.
- Pour the cooking liquid into a measuring cup.
- Let the fat rise to the top for a minute.
- Spoon off some fat if there is a large amount.
- Pour the liquid into a saucepan.
- Mix 2 tablespoons of cornstarch with 2 tablespoons of cold water.
- Bring the cooking liquid to a gentle simmer.
- Whisk in the cornstarch mixture.
- Cook for 1 to 2 minutes, until thickened.
- Taste before adding salt.
For a richer gravy, make a roux with 2 tablespoons of butter and 2 tablespoons of flour. Whisk in about 2 cups of strained cooking liquid. Simmer until smooth and thick.
The broth may already contain salt. Taste the gravy after thickening rather than salting it at the start.
Common Problems and Fixes
The turkey is still below 165°F
Put the lid back on and continue cooking on LOW. Check the thickest part again after 20 to 30 minutes.
If the roast has been in the slow cooker for a long time but remains cold in the center, check that the cooker is plugged in and heating correctly. A faulty appliance should not be used for meat.
The turkey is dry
Dry turkey usually means it cooked too long or was sliced too soon. Add warm broth or gravy when serving.
For the next roast, begin checking the temperature earlier. A smaller roast may finish much sooner than the cooking chart suggests.
The turkey is tough
Turkey can become firm when it is overcooked. Bone-in turkey may also need more time before its connective tissue softens.
Check the temperature and texture together. If the turkey is safe but firm, slice it thinly and serve it with gravy.
The roast has no color
This is normal. Moist heat does not create the browned crust produced by an oven or skillet.
For color, brown the raw roast in a skillet before slow cooking, if the shape allows. You can also broil the cooked roast briefly after it reaches 165°F.
The cooking liquid tastes weak
Add onion, celery, garlic, herbs, or low-sodium broth next time. You can also reduce the strained liquid in a saucepan after cooking.
Season at the end. Slow-cooker liquid becomes more concentrated as it reduces.
Food-Safety Rules for Slow Cooker Turkey
Use these basic rules when cooking and storing turkey in a U.S. home kitchen:
- Thaw turkey in the refrigerator, cold water, or microwave—not on the counter.
- Do not cook a frozen turkey roast in a slow cooker.
- Wash your hands before and after handling raw turkey.
- Keep raw turkey and its juices away from ready-to-eat foods.
- Use a food thermometer to verify 165°F.
- Do not rely on the meat’s color or the cooking time alone.
- Refrigerate leftovers within 2 hours.
- Store leftovers in shallow containers so they cool quickly.
- Use refrigerated cooked turkey within 3 to 4 days, or freeze it for longer storage.
The USDA recommends reheating leftovers to 165°F. Reheat only the amount you plan to eat when possible. Repeated heating can reduce quality and make the turkey dry.
If you use a turkey roast with stuffing inside, follow the package directions closely. Stuffed products may need a different cooking method and time.
Can You Cook a Whole Turkey in a Slow Cooker?
A whole turkey is generally too large for a standard home slow cooker. The bird may not fit safely, and the cooker may not heat the meat evenly.
Use a slow cooker for a turkey breast roast, boneless turkey roast, or smaller turkey pieces instead. Cook a whole turkey in an oven or another method designed for its size.
A turkey breast roast is also easier to portion. It gives you a similar lean meat option without the space and longer cooking time required for a whole bird.
What to Serve With Slow Cooker Turkey Roast
Slow cooker turkey works well with simple side dishes:
- Mashed potatoes
- Roasted or steamed green beans
- Cranberry sauce
- Stuffing prepared separately
- Sweet potatoes
- Dinner rolls
- Roasted carrots
- Macaroni and cheese
- A green salad
For a complete meal, start the turkey first and prepare quick sides while it cooks. Keep stuffing separate unless the product instructions specifically say it can be cooked safely with the turkey.
Frequently Asked Questions
Can I put a frozen turkey roast in the slow cooker?
No. Thaw the roast in the refrigerator before cooking. A frozen roast may take too long to reach a safe temperature in a slow cooker.
Should I cook turkey roast on LOW or HIGH?
LOW is usually the better choice because it gives the meat a gentler cooking process and a wider time window. HIGH can work when the product instructions allow it, but use a thermometer rather than relying on a fixed time.
Do I need to brown the turkey first?
No. Browning is optional. It adds color and roasted flavor but does not make the turkey safer or guarantee that it will stay moist.
Can I cook vegetables with the turkey?
Yes. Onion, carrot, celery, garlic, and potatoes can cook with the turkey. Cut dense vegetables into similar-size pieces and place them beneath or around the roast.
How long does cooked turkey roast last in the refrigerator?
Use refrigerated leftovers within 3 to 4 days. Store the turkey in shallow, covered containers and refrigerate it within 2 hours of cooking.
Can I use the slow cooker to reheat turkey?
You can use a slow cooker for some reheating tasks, but it may heat leftovers slowly and unevenly. Reheat turkey to 165°F, and use an oven, stovetop, or microwave when you need faster, more even heating.
Key Takeaways
- Use a thawed 2- to 3-pound turkey roast.
- Add about 1 cup of broth to a 4- to 6-quart slow cooker.
- Cook on LOW for about 4 to 6 hours.
- Check the thickest part with a thermometer.
- Remove the turkey when it reaches 165°F.
- Rest it for about 15 minutes before slicing.
- Refrigerate leftovers within 2 hours and use them within 3 to 4 days.
Conclusion
A slow cooker makes turkey roast simple: season the thawed roast, add a small amount of broth, cook it on LOW, and check the center with a thermometer. The key decision is not the clock. It is reaching 165°F without leaving the lean turkey in the cooker long enough to dry out.
For the best result, start checking early, rest the roast before slicing, and serve it with the cooking juices or gravy.
