Instructions
Prepare the Herb Butter
In a small bowl, mix softened butter with minced garlic, rosemary, thyme, sage, salt, pepper, and paprika (if using). This mixture will act as a flavor bomb, infusing the turkey with fresh, herbaceous notes while keeping it moist.
Season the Turkey
Pat the turkey breast dry with paper towels—this helps the herb butter stick. Gently loosen the skin (if your breast still has it) and rub about half the herb butter underneath, directly onto the meat. Rub the remaining butter all over the outside of the turkey breast.
Layer the Crockpot
Place the chopped onion, celery, and carrots in the bottom of the crockpot. These not only add flavor but also elevate the turkey slightly, helping it cook more evenly. Pour the chicken broth over the vegetables.
Place the Turkey in the Crockpot
Set the prepared turkey breast on top of the vegetables, skin-side up if applicable. Cover and cook on low for 5 hours, or until the internal temperature reaches 165°F. For a Butterball turkey breast roast or any store-bought variety, be sure to check doneness using a thermometer inserted into the thickest part.
Rest the Turkey
Once fully cooked, carefully transfer the turkey to a cutting board and tent it with foil. Let it rest for at least 10 minutes before slicing. This allows the juices to redistribute.
Make the Gravy
Strain the cooking liquid through a fine mesh strainer into a bowl or measuring cup. Discard solids. In a saucepan over medium heat, melt 2 tablespoons of butter. Add the flour and whisk constantly for about 1 minute to make a roux. Gradually pour in 1½ to 2 cups of the strained cooking liquid, whisking to prevent lumps. Simmer for 5–7 minutes, until thickened to your liking. Season with salt and pepper as needed.
Serve
Slice the turkey breast and pour the gravy over top. Serve hot alongside your favorite sides.
