How to Make Southwest Chicken Quinoa Casserole

  1. Preheat Oven: Begin by preheating your oven to 375°F (190°C). This ensures a hot environment for evenly cooking your casserole.

  2. Prep Baking Dish: Spray a 9x13-inch baking dish with cooking spray. This helps prevent sticking and makes cleanup a breeze after your savory creation is enjoyed!

  3. Combine Ingredients: In the prepared baking dish, mix together the diced chicken, spices, quinoa, tomatoes, sauce, water or broth, bell pepper, jalapeño, cauliflower rice, black beans, corn, green chiles, and 1 ¼ cups of cheese. Stir until everything is well combined.

  4. Cover and Bake: Tightly cover the dish with aluminum foil and bake it in your preheated oven for 50-60 minutes. This will cook the quinoa until it is tender and absorbent.

  5. Add Cheese Topping: After baking, carefully remove the foil. Sprinkle the remaining cheese on top, then return the dish to the oven and bake uncovered for an additional 3-5 minutes. You’re looking for the cheese to melt into a gooey delight!

  6. Cool and Serve: Allow your casserole to cool for about 15 minutes before serving. This resting time lets everything settle and makes serving easier—then add your favorite toppings!

Optional: Top with fresh avocado slices or a squeeze of lime for extra flavor!

Southwest Chicken Quinoa Casserole Recipe FAQs
