Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 boneless skinless turkey breast (about 3 pounds)

1/4 cup butter, softened

2 tablespoons garlic paste or minced garlic (about 6 cloves)

1 tablespoon fresh rosemary, finely chopped

1 tablespoon fresh sage, finely chopped

1 tablespoon fresh thyme, finely chopped

2 teaspoons pink sea salt

1/2 teaspoon freshly ground black pepper

1/3 cup keto maple syrup

3 tablespoons stone ground mustard or Dijon mustard

2 tablespoons Worcestershire sauce

2 tablespoons tamari or coconut aminos

1/2 cup water (for roasting pan)

Directions

Preheat the oven to 350°F (175°C). Remove the turkey breast from the refrigerator about 30 to 60 minutes before cooking so it can come to room temperature.

In a small bowl, combine the softened butter, garlic paste, rosemary, sage, thyme, salt, and black pepper. Mix until well blended and fragrant.

Pat the turkey breast dry using paper towels. Place it on a wire rack set inside a rimmed baking sheet or shallow roasting pan.

Rub the herb butter mixture evenly over the entire turkey breast, coating the top and sides.

Pour the water into the bottom of the roasting pan. This helps prevent the drippings from burning during cooking.

In a small saucepan, combine the keto maple syrup, mustard, Worcestershire sauce, and tamari. Bring the mixture to a gentle boil, then reduce the heat and simmer for 10 to 15 minutes until slightly thickened. Remove from heat and set aside.

Roast the turkey breast in the oven for about 1 hour, or approximately 20 minutes per pound.

After the turkey has roasted for 30 minutes, brush half of the maple mustard glaze over the surface of the turkey.

At about 45 minutes of cooking time, brush the remaining glaze over the turkey.

Continue roasting until the internal temperature reaches 160°F (71°C) in the thickest part of the meat.

Remove the turkey from the oven and loosely cover it with foil. Allow it to rest for 10 to 20 minutes before slicing so the juices redistribute throughout the meat.

Slice and serve warm.
