- 1 (15-oz) can black beans, drained and rinsed (or substitute 1 ½ cups cooked lentils)
- 1 ½ cups frozen corn
- 1 (4-ounce) can diced green chiles
- 8 ounces (one block or bag) shredded colby jack or cheddar cheese (2-2 ½ cups), divided
- 2 teaspoons chili powder
- ½ teaspoon ancho chili powder (or an additional ½ teaspoon chili powder for less heat)
- 1 ½ teaspoons garlic powder
- 1 teaspoon ground cumin
- ½ teaspoon onion powder
- ½ teaspoon dried oregano
- ½ teaspoon smoked paprika (or regular paprika)

- Sour cream
- Salsa
- Chopped fresh cilantro
- Green onion
- Jalapeño slices
- Fresh lime wedges
- Sliced or diced avocado
How to Make Southwest Chicken Quinoa Casserole Recipe Step-by-Step
- Step 1: Preheat your oven to 375℉. Lightly coat a 9×13-inch glass baking dish with cooking spray to prevent sticking and set it aside for assembling the casserole.
- Step 2: In the prepared baking dish, add the cooked and diced chicken along with all the seasonings—chili powder, ancho chili powder, garlic powder, cumin, onion powder, oregano, smoked paprika, and salt. Then add the uncooked quinoa, fire-roasted tomatoes, tomato sauce, water (or chicken broth), diced bell pepper, jalapeno, black beans, frozen cauliflower rice, corn, diced green chiles, and about 1 ¼ cups of the shredded cheese. Stir everything thoroughly to ensure the spices and ingredients are well combined.
- Step 3: Cover the baking dish tightly with aluminum foil to trap moisture. Bake in the preheated oven for 50 to 60 minutes, or until the quinoa is tender and fully cooked through.
- Step 4: Remove the foil and sprinkle the remaining cheese evenly over the casserole. Return to the oven and bake uncovered for an additional 3 to 5 minutes, just until the cheese melts and becomes bubbly. Once done, remove from the oven and allow the casserole to rest for 15 minutes before serving, which helps it set and makes serving easier.
- Step 5: Serve the casserole warm with your choice of optional toppings such as sour cream, salsa, chopped fresh cilantro, green onions, jalapeño slices, fresh lime wedges, or sliced avocado to add freshness and extra flavor.
- Step 6: Store any leftover casserole in an airtight container in the refrigerator for up to 4 days. It also freezes well for longer-term storage—just thaw and reheat when ready to enjoy.
