If you're looking to spice up your dinner routine, this Mexican Fiesta Casserole is just the ticket. It's a hearty, flavor-packed dish that's perfect for feeding a crowd or making ahead for a busy weeknight. Let's dive into this vibrant, satisfying meal that brings a little fiesta to your table!
The heart of this dish is the combination of ground beef and fresh vegetables—onion, garlic, red bell pepper, and green bell pepper—providing a hearty, savory base. Black beans add a creamy texture and protein boost, while corn contributes a touch of sweetness. The diced tomatoes with green chilies bring a juicy, spicy kick. Cumin and chili powder are your go-to spices here, adding depth and warmth. And who can resist the gooey, melty goodness of shredded cheddar cheese? Finally, the tortilla chips on top provide a delightful crunch that contrasts with the softness of the casserole.
This casserole pairs beautifully with a simple side salad dressed with lime vinaigrette. For a complete Mexican feast, serve it with a side of refried beans and some fresh guacamole. A dollop of sour cream on top of each serving can also balance the spiciness perfectly.
To start, preheat your oven to 375°F (190°C). This step ensures your oven is ready when you are. In a large skillet, heat olive oil over medium heat. Add chopped onion and minced garlic, sautéing until the onions turn translucent. This creates a fragrant base for your casserole.
Next, add the ground beef to the skillet. Cook it until it's browned, stirring occasionally to break it up. Once browned, mix in the red and green bell peppers. These should cook for about 3–4 minutes until they begin to soften.
Stir in the black beans, corn, diced tomatoes with green chilies, cumin, chili powder, salt, and pepper. Let this mixture simmer for about 10 minutes, allowing the flavors to meld beautifully.
Transfer the mixture into a 9x13 inch baking dish. Top it with the shredded cheddar cheese and crushed tortilla chips. The cheese will melt into a gooey layer, while the tortilla chips will provide a satisfying crunch.
Bake in your preheated oven for 20–25 minutes. You'll know it's ready when the cheese is melted and bubbly. Let the casserole cool for a few minutes before serving. Trust me, the wait is worth it!
