1-Getting started: Getting started with this taco casserole is simple and fun, ideal for beginners or those short on time. Begin by preheating your oven to 350°F (175°C) and greasing a baking dish for even cooking. This step ensures your casserole comes out perfectly melted and hot in just 15-20 minutes of baking.

2-First, heat the olive oil in a skillet over medium heat. Add the 1 pound of lean ground beef and the chopped half of a medium onion, cooking until the beef is browned and the onion softens. This creates a flavorful base that ties everything together.

3-Next, stir in the seasonings: 1 tablespoon chili powder, 1/2 teaspoon garlic powder, and 1/2 teaspoon ground cumin. Mix well and cook for a few minutes to let the flavors blend. For added variety, you might try linking to similar recipes, like our chicken taco casserole for a lighter twist.

4-Then, combine the beef mixture with the drained black beans, corn, salsa, and half of the 2 cups shredded cheese. Spread the crushed tortilla chips as the base layer in your baking dish, then add the beef mixture on top. Finally, sprinkle the remaining 1 cup of cheese over everything.

5-Bake uncovered at 350°F (175°C) for 15-20 minutes until it’s hot and the cheese melts beautifully. Let it rest for a moment before serving, and don’t forget those optional toppings like avocado or sour cream for extra flair.
