Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Place 8 oz boneless, skinless chicken thighs on a baking sheet, drizzle with 1 tbsp olive oil, and season with 1 tsp chopped rosemary, 1 tsp chopped thyme, 1/4 tsp salt, and 1/8 tsp black pepper. Toss to coat evenly.
  2. Step 2: Bake for 22-25 minutes until golden and cooked through, flipping halfway. Remove from oven and let rest.
  3. Step 3: While chicken bakes, combine 1.5 cups chopped cauliflower, 1 clove minced garlic, 1/4 tsp salt, and 1/4 cup water in a saucepan. Bring to a boil, then reduce heat to low and simmer for 15 minutes until very tender.
  4. Step 4: Drain cauliflower, then return to pan with 1 tbsp unsalted butter and 2 tbsp heavy cream. Mash until smooth, adding a splash of water if too thick. Season with salt and pepper to taste.
  5. Step 5: Slice rested chicken and serve with cauliflower mash.
