Ingredients

Instructions

  1. Step 1: Pat chicken thighs dry with paper towels and season both sides evenly with 1/2 tsp salt and 1/4 tsp black pepper.
  2. Step 2: Heat 2 tbsp avocado oil in a large skillet over medium-high heat until shimmering. Place chicken skin-side down and cook undisturbed for 10 minutes until skin is deep golden brown and crispy.
  3. Step 3: Flip chicken and cook for 8 minutes more, until internal temperature reaches 165°F (use a meat thermometer for accuracy).
  4. Step 4: Remove chicken and set aside. Add minced garlic to the same skillet and sauté for 1 minute until fragrant but not browned.
  5. Step 5: Pour in 1/4 cup heavy cream and 1 tbsp Dijon mustard, stirring constantly until the sauce simmers and thickens slightly (about 2 minutes).
  6. Step 6: Stir in 1 tsp fresh rosemary, then return chicken to the skillet, spooning sauce over the top. Cook for 2 more minutes to reheat and absorb flavors.
