If you're craving a dish that combines all your favorite taco flavors into one easy-to-make meal, this Authentic Taco Casserole is for you. It's perfect for busy weeknights or casual gatherings, bringing comfort and satisfaction to the table with every bite.
Ground beef is the hearty base of this casserole, providing protein and rich flavor. Taco seasoning adds the essential spices that make this dish taste like your favorite Mexican meal. Onion and garlic are sautéed to build a flavorful foundation. Black beans and corn introduce texture and a touch of sweetness, while salsa brings moisture and zest. Shredded cheddar cheese melts into a gooey, irresistible topping. Crushed tortilla chips add a satisfying crunch. Sour cream, black olives, green onions, and diced tomatoes finish the dish with fresh, creamy, and tangy notes.
This casserole pairs perfectly with a simple green salad dressed with lime vinaigrette. You can also serve it with a side of guacamole or extra salsa for dipping. If you're hosting, consider offering a toppings bar with items like chopped cilantro, diced avocados, or sliced jalapeños for guests to customize their plates.
Start by preheating your oven to 350°F (175°C). While the oven heats, grab your trusty skillet and drizzle in a tablespoon of olive oil over medium heat. Toss in the diced onion and minced garlic, letting them sauté until the onion turns translucent, about 3-4 minutes. This step builds a fragrant base for your casserole.
Next, add the ground beef to the skillet. Break it up with a spatula as it cooks, ensuring it's evenly browned. Once the beef is cooked through, drain any excess fat to keep the dish from becoming greasy.
Sprinkle in the taco seasoning, then stir in the black beans, corn, and half of the salsa. Let this mixture simmer for about 5 minutes, allowing the flavors to meld together nicely.
Now, take your 9x13 inch baking dish and spread half of the crushed tortilla chips evenly across the bottom. Pour the beef mixture over the chips, spreading it out to cover all edges. Top it off with the remaining chips, creating a crunchy layer.
Pour the rest of the salsa over the chips and sprinkle the shredded cheddar cheese evenly on top. Place the dish in your preheated oven and bake for about 20 minutes, or until the cheese is melted and bubbly.
Once baked, let the casserole cool for a few minutes. Just before serving, add dollops of sour cream, sprinkle on the black olives, green onions, and diced tomatoes for a fresh finish.
