Ingredients
  

For the Casserole
  • 1 tablespoon cooking spray Prevents sticking; use any non-stick spray.
  • 1 lb boneless, skinless chicken (cooked and diced) Main protein source; can substitute rotisserie chicken for easy prep.
  • 2 teaspoons chili powder Adds heat and flavor; adjust according to spice preference.
  • 0.5 teaspoon ancho chili powder Provides a smoky depth; substitute with more chili powder for a milder taste.
  • 1.5 teaspoons garlic powder Enhances savory taste; optional fresh garlic can be used for more punch.
  • 1 teaspoon ground cumin Adds earthy flavor; essential for authentic Tex-Mex experience.
  • 0.5 teaspoon onion powder Supplements savory notes; fresh onion is a great alternative if you prefer.
  • 0.5 teaspoon dried oregano Adds herbal flavor; consider substituting with Italian seasoning for a twist.
  • 0.5 teaspoon smoked paprika Provides a smoky flavor; use regular paprika for a milder option.
  • 1 teaspoon fine salt Balances flavors; feel free to adjust based on dietary needs.
  • 0.5 cup dry quinoa (uncooked) Nutrient-dense grain that provides filling substance; remember to rinse it first.
  • 1 14-oz can fire-roasted canned tomatoes Contributes moisture and flavor; diced fresh tomatoes are a lovely alternative!
  • 1 8-oz can tomato sauce Adds richness; homemade tomato sauce can be a delightful swap.
  • 1 cup water or low-sodium chicken broth Use broth for enhanced flavor; it really elevates the dish.
  • 1 medium bell pepper (diced) Brings sweetness and crunch; any color will work beautifully.
  • 1 jalapeno diced, seeds removed Adds a kick; omit for a milder casserole.
  • 1 10-oz bag frozen cauliflower rice A low-carb option; can be replaced with regular rice or skipped altogether.
  • 1 15-oz can black beans (drained and rinsed) Provides protein and fiber; cooked lentils make a great substitute!
  • 1.5 cups frozen corn Adds sweetness and texture; fresh corn can be fantastic in season.
  • 1 4-oz can diced green chiles Offers mild heat; can be left out if you prefer less spice.
  • 8 oz shredded colby jack or cheddar cheese (divided) Adds creaminess; opt for dairy-free cheese for a lactose-free option.
Optional Toppings
  • sour cream Adds cool creaminess; perfect for balancing the spices.
  • salsa A flavorful addition; fresh or jarred works well.
  • cilantro Brightens the dish with freshness; a sprinkle is all you need.
  • green onion Adds crunch and flavor; slice thinly for the best effect.
  • jalapeño slices For those who want to kick up the heat further.
  • lime wedges A squeeze of lime lifts the flavors beautifully.
  • avocado Creamy avocado complements the casserole superbly; a must-try!
