Key Ingredients and Flexible Substitutions
This dish is wonderfully adaptable to suit different tastes and dietary needs:
- Protein: Lean ground beef is traditional for its rich flavor and texture, but ground turkey is a lighter, equally delicious alternative. For vegetarian options, beans, lentils, or quinoa work great.
- Salsa: Whether store-bought or homemade, salsa adds moisture and a tangy kick.
- Beans and Olives: Ranch-style beans, black beans, or kidney beans add heartiness, while sliced black olives contribute a salty, briny contrast.
- Tortilla Chips: Lightly salted chips provide a crunchy base and absorb the flavorful layers.
- Cheese and Cream: A mix of cheddar and cream cheese creates a creamy, cheesy topping. You can also substitute Greek yogurt for sour cream and try different cheeses like Monterey Jack or Pepper Jack.
- Fresh Produce: Green onions and tomatoes add freshness and balance to the richness.
These ingredients can be mixed and matched to personalize your casserole without losing the authentic taste that defines Mexican cooking.
How to Make Mexican Casserole — Step by Step
- Preheat your oven to 325°F (163°C) to ensure even baking and a bubbly finish.
- Cook the meat: Brown the ground beef or turkey in a skillet over medium-high heat, draining any excess fat.
- Add salsa and beans: Stir in salsa, beans, chopped onion, taco seasoning, cream of chicken soup, and water. Simmer gently until heated through and flavors meld.
- Layer the casserole: Grease a 9×13-inch baking dish. Spread a layer of crushed tortilla chips, then add the meat mixture, followed by a sprinkle of cheddar cheese. Repeat layers until all ingredients are used.
- Bake: Cover with foil and bake for 20-30 minutes until hot and bubbly.
- Broil (optional): Remove the foil and broil for a few minutes to brown the cheese on top.
- Rest before serving: Let the casserole sit 5-10 minutes to set, making it easier to serve.
- Serve: Top with sour cream and salsa for a perfect finishing touch.
Perfect Pairings and Serving Ideas
