Ingredients

  • 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)

Instructions

  1. Preheat the oven to 350°F (175°C). Remove the turkey breast from the refrigerator 30–60 minutes before cooking to bring it closer to room temperature.
  2. In a small bowl, mix the softened butter, garlic paste, rosemary, sage, thyme, salt, and black pepper until well combined.
  3. Pat the turkey breast dry with paper towels and place it on a wire rack set inside a rimmed baking sheet or shallow roasting pan.
  4. Rub the herb butter mixture evenly over the entire turkey breast, coating the top and sides.
  5. Pour the water into the bottom of the roasting pan to prevent drippings from burning.
  6. In a small saucepan, combine the keto maple syrup, mustard, Worcestershire sauce, and tamari. Bring to a gentle boil, then reduce heat and simmer for 10–15 minutes until slightly thickened.
  7. Place the turkey in the oven and roast for about 1 hour, approximately 20 minutes per pound.
  8. After 30 minutes of roasting, brush half of the maple mustard glaze over the turkey.
  9. At about 45 minutes of cooking time, brush the remaining glaze over the turkey.
  10. Continue roasting until the internal temperature reaches 160°F (71°C) in the thickest part.
  11. Remove the turkey from the oven and loosely cover with foil. Let it rest for 10–20 minutes before slicing.
  12. Slice the turkey breast and serve warm.

Notes

  • Allowing the turkey to rest after roasting keeps the meat juicy and tender.
  • If using dried herbs, substitute 1 teaspoon dried herbs for each tablespoon of fresh herbs.
  • Bone-in turkey breast can be used but may require additional cooking time.
  • Placing sliced onions or carrots under the turkey can replace a roasting rack if needed.
  • Leftover turkey works well in sandwiches, salads, wraps, or low-carb bowls.
