Ingredients List
Here’s what you’ll need to create this delightful easy Mexican casserole. Make sure to have everything prepped and ready to go!
- 1 lb ground beef: Use lean ground beef for a healthier option, but don’t skimp on flavor!
- 1 can black beans: Make sure to drain and rinse these to keep things from getting too mushy.
- 1 can corn: Again, drain it well to avoid excess liquid in the casserole.
- 1 can diced tomatoes: No need to drain this one; the juices will add extra flavor!
- 1 packet taco seasoning: Feel free to use your favorite brand or even make your own if you’re feeling adventurous!
- 2 cups shredded cheese: I love using a Mexican blend, but feel free to use cheddar or whatever cheese you prefer.
- 1 cup tortilla chips: These will add a nice crunch, so don’t skip this step! Crush them slightly for better layering.
- 1/2 cup chopped onions: I usually stick with yellow or white onions for a mild flavor.
- 1/2 cup chopped bell peppers: Mix up the colors for a vibrant look—red, green, or yellow all work beautifully!
How to Prepare Instructions
- First things first, preheat your oven to 350°F (175°C). This step is crucial for getting that cheesy goodness nice and bubbly!
- While the oven heats up, grab a skillet and brown the 1 lb ground beef over medium heat. Add in the 1/2 cup chopped onions and 1/2 cup chopped bell peppers and cook until the beef is no longer pink and the veggies are tender, about 5-7 minutes. Oh, the aroma is heavenly!
- Now, it’s time to mix in the good stuff! Stir in the 1 can black beans (drained), 1 can corn (drained), 1 can diced tomatoes, and the 1 packet taco seasoning. Make sure everything is well combined and let it simmer for a few minutes. This step really allows those flavors to meld together.
- Grab a baking dish and start layering! First, spread half of the beef mixture evenly on the bottom. Then, add a layer of 1 cup tortilla chips, followed by a generous sprinkle of 2 cups shredded cheese.
- Repeat the layers with the remaining beef mixture, tortilla chips, and finish off with the rest of the cheese on top. You want that gorgeous cheesy layer to melt beautifully!
- Pop the dish into the preheated oven and bake for 25-30 minutes, until the cheese is melted and bubbly. You’ll know it’s done when you can’t resist peeking inside!

Tips for Success
To really nail this easy Mexican casserole, here are some of my top tips! First, be sure to drain all canned ingredients thoroughly; excess liquid can make your casserole soggy, and nobody wants that! When browning the beef, don’t rush it—letting it cook until it’s nicely browned adds depth of flavor. If you like a bit of heat, consider adding some diced jalapeños or a sprinkle of cayenne pepper to the beef mixture; it amps up the flavor beautifully!
Also, feel free to mix up the cheeses! A combination of Monterey Jack and cheddar gives a lovely meltiness. And for an extra layer of flavor, try adding some fresh cilantro or a squeeze of lime juice right before serving. Trust me, those little touches can take your casserole from good to absolutely fabulous!
Variations
One of the best things about this easy Mexican casserole is how adaptable it is! If you’re in the mood for something different, try swapping out the ground beef for ground turkey or even shredded chicken for a lighter option. You can also go vegetarian by leaving out the meat entirely and adding more beans or some sautéed mushrooms for that hearty texture.
Feeling adventurous? Toss in some diced zucchini or corn to add extra veggies, or spice things up with a packet of chipotle seasoning instead of taco seasoning for a smoky kick. You can even customize the cheese—feta or pepper jack will give it a unique twist! And don’t forget, you can always play with the toppings; a sprinkle of fresh avocado or a dollop of salsa can really elevate the dish. The possibilities are endless, so feel free to make it your own!
Serving Suggestions
When it comes to serving this easy Mexican casserole, I love to keep things simple yet delicious! It pairs perfectly with a dollop of sour cream on top—trust me, the creaminess cuts through the spices beautifully. If you’re feeling fancy, a sprinkle of chopped fresh cilantro adds a lovely pop of color and flavor.
On the side, I recommend some guacamole for that creamy goodness and maybe some pico de gallo for a fresh, zesty kick. A simple green salad with a light vinaigrette also complements the richness of the casserole perfectly. And don’t forget the tortilla chips! They’re great for scooping up every last bit of cheesy goodness. This meal is sure to please everyone at the table!
