Slow Cooker Turkey Breast
Slow cooker turkey breast with garlic herb butter under the skin, cooked on a bed of onion for 6 hours, then broiled to crisp the skin.

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.

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.
