Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Place 1.5 lbs chicken thighs in a baking dish, drizzle with 2 tbsp avocado oil, and sprinkle with 4 minced garlic cloves and 1 tbsp chopped rosemary. Rub to coat evenly.
  2. Step 2: Roast for 25 minutes until chicken is golden-brown and internal temperature reaches 165°F.
  3. Step 3: While chicken cooks, heat 1 tbsp unsalted butter in a saucepan over medium heat. Add 2 cups riced cauliflower, 1 tsp lemon zest, 1/2 tsp sea salt, and 1/4 tsp black pepper. Cook for 8 minutes, stirring occasionally, until cauliflower is tender.
  4. Step 4: Stir in 2 tbsp heavy cream and cook for 2 more minutes until mixture thickens and coats the back of a spoon. Remove from heat.
  5. Step 5: Serve roasted chicken over cauliflower mash, spooning any pan juices from the chicken onto the dish.
