Slow Cooker Turkey Breast
01Why this one

Cooking a turkey breast in the slow cooker frees up the oven when you need it most. Garlic and herb butter goes under the skin, the breast sits on a bed of onions, and six hours later it is juicy all the way through.

A few minutes under the broiler at the end crisps the skin, which the slow cooker cannot do. It is naturally keto at about 2g net carbs per serving.

Why You’ll Love This Slow Cooker Turkey Breast

  • Juicy turkey with no oven needed.
  • Herb butter under the skin keeps it moist.
  • Perfect for smaller holiday gatherings.
  • Leftovers for days.
02Before you cook

What You’ll Need

Bone-in turkey breast
About 4 lb, which gives roughly 2.8 lb of meat and skin.
Butter
Softened and mashed with herbs.
Rosemary, thyme and sage
Classic turkey herbs.
Onion
Acts as a rack to lift the turkey out of the liquid.
Chicken broth
Keeps it moist and makes a gravy.

How This Recipe Comes Together

Herb butter goes under and over the skin, then the breast sits on thick onion slices in the slow cooker with broth poured around. It cooks on low for six hours until the thickest part reaches 165F. A quick broil crisps the skin before resting and carving.
