Crockpot Turkey Breast Recipe

Equipment

Crockpot (6-quart size recommended)
Meat thermometer
Small mixing bowl
Basting brush
Sharp carving knife
Cutting board
Baking dish
Silicone tongs

Ingredients

4 lbs bone-in turkey breast
1 onion, sliced
1/4 cup unsalted butter, softened
1 teaspoon poultry seasoning
1 teaspoon salt
1/2 teaspoon black pepper
Fresh thyme
Fresh rosemary

Instructions

Lay the sliced onions on the bottom of the crockpot.
In a small bowl, mix the softened butter, poultry seasoning, salt, and pepper. Carefully spread this mixture under the turkey skin and all over the top.
Sprinkle a bit more salt on the turkey, then place the fresh thyme and rosemary around it for added flavor.
Set the crockpot to low heat and cook for 5–6 hours. Start checking the internal temperature at 5 hours. When the thickest part of the turkey reaches 165°F, it’s done.

Let the turkey rest for 15 minutes before slicing. Enjoy!

Handy Tips For Cooking Crockpot Turkey Breast

Choose Bone-In for Flavor: Bone-in turkey breasts tend to be more flavorful and stay juicier during cooking.
Use Fresh Herbs: Fresh thyme and rosemary make a huge difference in taste. They add an aromatic depth that’s perfect for turkey.
Butter Under the Skin: Spreading butter under the skin helps lock in moisture and infuses the meat with flavor.
Check Temperature Regularly: Turkey can overcook quickly in a slow cooker. Start checking the internal temperature at 5 hours to avoid dryness.
Let It Rest: After cooking, give the turkey breast at least 10–15 minutes to rest before slicing. This keeps the juices from escaping and helps retain moisture.

What To Serve With Crockpot Turkey Breast?

For a balanced and delicious meal, try pairing crockpot turkey breast with sides that complement its savory flavors. Here are a few classic options:

Mashed Potatoes: Creamy mashed potatoes make the perfect side to soak up all those turkey juices.
Roasted Vegetables: Roasted carrots, Brussels sprouts, or green beans add color and flavor to the plate.
Stuffing: Classic stuffing pairs wonderfully with turkey, especially with added herbs like sage or parsley.
Cranberry Sauce: The sweetness and tang of cranberry sauce balance the savory turkey perfectly.
Dinner Rolls: Soft, buttery rolls are ideal for mopping up any leftover sauce or gravy.

How To Store Crockpot Turkey Breast?

To keep your turkey fresh, follow these storage tips:

Refrigerate Promptly: Place any leftovers in an airtight container within two hours of cooking.
Use Within 3–4 Days: Turkey can stay fresh in the fridge for up to four days. Reheat only what you plan to eat, as reheating multiple times can dry out the meat.

Is Cooking A Turkey In A Slow Cooker Safe?

Absolutely. Cooking turkey in a slow cooker is safe, as long as the internal temperature reaches at least 165°F. Here’s what to keep in mind:

Cook on Low for Best Results: Low heat ensures even cooking and prevents the turkey from drying out.
Use a Meat Thermometer: A meat thermometer is key for safety. Insert it into the thickest part of the breast to ensure a temperature of 165°F before serving.

Should I Cover Turkey Breast When Cooking In The Crockpot?

Yes, always cover the turkey breast while it cooks in the crockpot.

The lid traps steam and moisture, which helps keep the turkey juicy and tender.

Lifting the lid releases heat, so keep it closed as much as possible for consistent cooking.

Benefits Of Slow Cooking A Turkey Breast

Slow cooking offers a few advantages over traditional oven roasting:

Moisture-Rich Results: The crockpot’s low, slow heat keeps the turkey juicy and prevents it from drying out.
Hands-Free Cooking: With the crockpot, you can set it and forget it—perfect for busy days.
Even Cooking: Slow cooking gently heats the turkey, helping it cook more evenly without overcooking the outer layers.
Enhanced Flavor: Slow cooking allows flavors from the herbs and seasonings to fully infuse, giving the turkey a deep, rich taste.

How To Reheat Turkey Breast?

Reheating turkey breast so it stays moist and flavorful can be easy with a few simple steps. Here’s how to reheat it perfectly:

In the Oven:
- Preheat the oven to 300°F (150°C).
- Place the sliced turkey in an oven-safe dish and add a splash of broth or water to keep it moist.
- Cover the dish with foil and heat for 20–30 minutes or until warmed through.
In the Microwave:
- Place slices on a microwave-safe plate and cover with a microwave-safe lid.
- Add a little broth or water to prevent it from drying out.
- Reheat in short bursts (30 seconds at a time), checking often to avoid overcooking.
In a Skillet:
- Heat a skillet over medium-low heat and add a splash of broth.
- Place the turkey slices in the skillet, cover, and warm for a few minutes, flipping halfway.

How Long To Cook Turkey Breast In The Slow Cooker?

The cooking time for turkey breast in a slow cooker depends on the size of the turkey and the heat setting you choose. Here’s a simple guide:

For a 4-5 lb turkey breast:
- On Low: Cook for 5–6 hours.
- On High: Cook for 3–4 hours.
For a smaller or boneless turkey breast:
- On Low: 4–5 hours.
- On High: 2–3 hours.

Use a meat thermometer to check the internal temperature of the turkey. When it reaches 165°F (74°C) at the thickest part, it’s fully cooked and safe to eat.
