Instructions

  1. Step 1: Preheat oven to 375°F. Cut 1.5 pounds boneless skinless chicken thighs into 1-inch pieces and toss with 1 teaspoon salt, 1/2 teaspoon black pepper, and 1 teaspoon dried thyme.
  2. Step 2: Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Add 3 cloves minced garlic and 1 medium diced yellow onion, sauté for 2-3 minutes until fragrant and translucent.
  3. Step 3: Add chicken pieces to the skillet and brown for 4-5 minutes, stirring occasionally until edges are golden but chicken is not fully cooked.
  4. Step 4: Stir in 3 cups broccoli florets and 2 cups cauliflower rice, sautéing for 3 minutes until broccoli is crisp-tender.
  5. Step 5: Pour in 1 cup chicken broth and 2 tablespoons coconut aminos, stirring to combine and deglaze the pan.
  6. Step 6: Transfer everything to a greased 9x13 inch baking dish and drizzle remaining 1 tablespoon olive oil on top.
  7. Step 7: Bake uncovered for 20-25 minutes until chicken is cooked through and casserole is bubbling.
  8. Step 8: Remove from oven and let rest for 5 minutes before serving to allow flavors to meld.
