• 1 teaspoon garlic, minced: Fresh garlic enhances the flavor, but jarred minced garlic works too.
• ½ teaspoon garlic salt: Provides seasoning while complementing the taco seasoning.
• 2 tablespoons taco seasoning: Use your favorite brand or make a homemade blend for more control over the flavors.
• 1 (4-ounce) can green chilies: Adds a mild kick to the casserole.
• 1 (15-ounce) can black beans, drained and rinsed: A healthy and protein-rich addition.
• 1 cup frozen corn: Sweet and crunchy, it balances the savory elements.
• 2 cups sour cream: Creamy and tangy, it ties the layers together.
• 1 (24-ounce) jar salsa: Pick your preferred style—chunky, smooth, mild, or spicy.
• 1 (9.25-ounce) bag corn chips: Adds crunch and texture. Reserve ½ cup for topping if desired.
• 2 cups cheddar cheese: Shredded cheese creates a gooey, irresistible topping.

Optional Toppings

• Sliced olives
• Chopped tomatoes
• Shredded lettuce
• Green onions
• Additional sour cream
• Crushed corn chips

Ingredient Substitutions and Flexibility

• Protein: Swap ground beef for ground chicken, turkey, or a plant-based alternative for a vegetarian version.
• Cheese: Use Monterey Jack, Colby, or a Mexican cheese blend if you prefer a different flavor.
• Beans: Replace black beans with pinto beans, kidney beans, or chickpeas.
• Sour Cream: Greek yogurt works well as a healthier alternative.
• Corn Chips: Tortilla chips or crushed tostadas can be used instead.

Step-by-Step Instructions

Follow these simple steps to create your own Mexican Casserole:

1. Preheat the Oven
   Preheat your oven to 350°F (175°C). This ensures even cooking and melts the cheese perfectly.
2. Cook the Ground Beef Mixture
   • In a large skillet over medium heat, brown the ground beef with chopped onions and minced garlic. Stir occasionally until the beef is cooked through and the onions are soft.
   • Drain any excess grease to keep the casserole from becoming too oily.
   • Mix in the garlic salt and taco seasoning, stirring well to coat the beef evenly.
3. Add Veggies and Chilies
   • Stir in the black beans, frozen corn, and green chilies. Heat the mixture until everything is warmed through, then set aside.
4. Prepare the Baking Dish
   • Spray the bottom of a 9×13-inch baking dish with nonstick cooking spray.
   • Spread a layer of corn chips evenly across the bottom of the dish. This forms the crunchy base of the casserole.
5. Layer the Ingredients
   • Spoon the beef mixture over the corn chips, spreading it out evenly.
   • Drop spoonfuls of sour cream over the meat layer, then spread it gently with a spatula.
   • Pour the salsa evenly over the sour cream.
   • Finish with a generous layer of shredded cheddar cheese.
6. Bake the Casserole
   • Place the dish in the preheated oven and bake for 30 minutes or until the cheese is fully melted and bubbling.
   • Let the casserole rest for 10 minutes before serving to allow the layers to set.

Beginner Tips and Notes

• Avoid Soggy Chips: To maintain a crunchy base, use thick, sturdy corn chips and serve immediately after resting.
• Checking Doneness: The casserole is ready when the cheese is melted and golden, and the edges are bubbling.
• Spice Level: If you prefer milder flavors, use mild salsa and skip the green chilies. For more heat, add a pinch of cayenne pepper to the beef mixture.
• Efficient Prep: Chop the onions and gather all ingredients before you start cooking to streamline the process.

Serving Suggestions

This casserole is a complete meal on its own, but you can elevate it with these sides and toppings:

• Sides: Serve with a simple green salad, Mexican rice, or refried beans for a more filling meal.
• Toppings: Let everyone customize their plate with chopped tomatoes, shredded lettuce, olives, or green onions.
• Sauces: Add a dollop of guacamole, a drizzle of hot sauce, or a squeeze of lime juice for extra flavor.

Storage and Reheating Tips

• To Store: Transfer leftovers to an airtight container and refrigerate for up to 5 days.
• To Freeze: Place the casserole in a freezer-safe container, label it, and freeze for up to 3 months. Thaw in the fridge overnight before reheating.
• To Reheat: Warm leftovers in the oven at 350°F or microwave individual portions until heated through.
