Turkey breast (3 to 5 pounds): Choose bone-in or boneless—the bone adds extra flavor, but either way, it’s the star of the show.
Unsalted butter (5 to 8 tablespoons): Softened butter carries the garlic and spices, making every bite rich and silky.
Fresh garlic (3 large cloves, minced + 8 sliced cloves): A garlic lover’s dream, giving the turkey a wonderfully fragrant boost.
Onion powder (2 teaspoons): Packs an umami punch and enhances the sweetness of roasted onions.
Ground paprika (1.5 teaspoons): Adds a subtle smoky warmth and beautiful color to the turkey’s crust.
Sea salt (2 teaspoons): A simple seasoning that perfectly balances and intensifies the flavors.
Yellow onions (2 large, sliced): Roasted right in the crock pot, they create an irresistible, caramelized base for the turkey to rest on.
Baby potatoes (1 to 1.5 pounds, optional): Great to add in for a full meal—soft and fluffy, soaking up all the garlicky juices.

How to Make Crock Pot Turkey Breast with Garlic Butter and Roasted Onions Recipe

Step 1: Prep Your Turkey

Start by taking your turkey breast out of its packaging and patting it dry using paper towels. This little step helps ensure the garlic butter will stick nicely and locks in moisture as it cooks. If your turkey has netting and it’s boneless, you can leave it on to keep the roast intact or remove it if you prefer—either way works fine.

Step 2: Make the Garlic Butter Rub

Mix the softened butter with minced garlic, onion powder, paprika, and sea salt in a small bowl. This luscious blend is what gives the turkey its incredible flavor and beautiful color once cooked. Then, rub it all over the turkey breast, spreading it evenly so every inch is coated with that buttery, garlicky goodness.

Step 3: Layer Your Crock Pot

Place the sliced yellow onions and garlic cloves at the bottom of your slow cooker. These not only add flavor but also create a natural roasting rack to keep the turkey elevated and juicy. Then, gently set the butter-rubbed turkey breast on top, no liquid needed because the butter and onions provide plenty of moisture.

Step 4: Slow Cook to Perfection

Put the lid on and cook on low for 5 to 6 hours or on high for 2 to 3 hours, depending on your schedule. Start checking the internal temperature early; you’re aiming for 165 degrees Fahrenheit to ensure food safety and tenderness. This slow, steady heat makes the turkey fork-tender and bursting with flavor.

Step 5: Optional Broil for Crispy Skin

If you’re craving that golden, crispy skin everyone loves, transfer your turkey to a baking sheet and broil for 8 to 10 minutes. Keep a close eye so it doesn’t burn—this step seals in the texture and adds a delightful contrast to the perfectly cooked meat.

Step 6: Rest and Slice

Let your turkey rest for at least 15 minutes once it’s out of the crock pot. This helps the juices redistribute so each slice is juicy and tender. Then, carve it up with a sharp knife and get ready to enjoy some seriously delicious turkey.

Garnishes

A sprinkle of fresh herbs like parsley or thyme adds a lovely burst of color and a hint of freshness that brightens the buttery richness of the turkey breast and onions. You can also drizzle a little bit of the buttery pan juices over each serving for extra moisture and flavor.

Side Dishes

This dish pairs wonderfully with simple sides that soak up those savory juices like creamy mashed potatoes, steamed green beans, or a crisp garden salad. The optional baby potatoes you cooked alongside can be a perfectly tender, flavorful side too, making it easy to create a balanced meal right in your crock pot.

Creative Ways to Present

For a special touch, arrange sliced turkey on a platter with caramelized onions drizzled on top and scattered smashed roasted garlic cloves. Add roasted vegetables or a bread basket on the side to turn this hearty meal into a stunning centerpiece that invites everyone to dig in.

Make Ahead and Storage

Storing Leftovers

Once your turkey breast has cooled, store any leftovers in an airtight container in the refrigerator. It should stay tender and delicious for up to 3 to 4 days, making it easy to enjoy tasty meals without extra cooking.

Freezing

You can freeze cooked turkey breast slices for up to 2 months. Wrap them tightly in plastic wrap and then place in a freezer-safe container or bag. Thaw in the refrigerator overnight when ready to use for quick lunches or easy dinners.

Reheating

To keep the turkey moist when reheating, cover it with a damp paper towel and warm in the microwave or oven on low heat. You can also gently reheat in a skillet with a bit of broth or butter to revive that fresh, homemade flavor.

FAQs

Can I use a boneless turkey breast for this recipe?

Absolutely! Both bone-in and boneless turkey breasts work well. Leaving the netting on a boneless breast helps it maintain shape during cooking, but you can take it off if you prefer.

Do I need to add any liquid to the crock pot?

No liquid is necessary. The butter and onions release enough moisture to cook the turkey perfectly, keeping it tender and flavorful without becoming watery.

How long does the turkey need to rest after cooking?

Resting for at least 15 minutes allows the juices to redistribute throughout the meat, resulting in more tender and juicy slices.

Can I add vegetables like carrots or celery to the crock pot?

Yes! Adding root vegetables like carrots or celery can add extra flavor and make it a one-pot meal, just place them under or around the turkey to cook alongside the onions.

Is there a way to make the skin crispier without broiling?

If you don’t want to broil, you can sear the turkey breast skin-side down in a hot pan with a bit of oil before placing it in the crock pot for a golden brown crust, but broiling post-cooking usually gives the best crispy finish.
