1. Crank your oven to 375°F and let it preheat while you build your casserole. Grease a 9×13 inch baking dish with cooking spray or butter.
2. In your largest skillet, cook the ground beef over medium heat for 6-8 minutes, breaking it up with a wooden spoon, until it’s browned and no longer pink. Drain most of the fat, but leave about a tablespoon for flavor and moisture.
3. Add your diced onion, red bell pepper, and minced garlic to the beef. Cook for about 5 minutes, stirring occasionally, until the vegetables are soft and the onion is translucent and starting to smell amazing.
4. Stir in the drained black beans, drained corn, diced tomatoes with their juice (important—don’t drain these), green chilies, chili powder, cumin, salt, and pepper. Let this mixture simmer for about 5 minutes so all the flavors meld together. Taste it now and adjust the seasoning—it should be boldly flavored since the tortillas and cheese will mellow it out.
5. Here’s the layering technique: spread about 1 cup of the meat mixture on the bottom of your prepared baking dish—this prevents the bottom tortillas from drying out. Arrange 4 corn tortillas over the meat, tearing them as needed to cover the surface completely with slight overlaps. Don’t leave gaps where filling can seep through.
6. Spread half of the remaining meat mixture evenly over the tortillas, then sprinkle with about 2/3 cup of the shredded cheese. Add another layer of 4 tortillas, arranged the same way. Spread the remaining meat mixture over these tortillas, then sprinkle with another 2/3 cup of cheese.
7. Finish with a final layer of 4 tortillas on top, then cover generously with the remaining cheese—about 2/3 cup or more if you’re feeling extra cheesy.
8. Cover the entire dish tightly with aluminum foil and bake for 25 minutes. This covered time steams the tortillas and melds everything together. Remove the foil and bake for an additional 10 minutes until the cheese on top is bubbly, golden, and starting to brown in spots.
9. Let the casserole rest for 10-15 minutes before cutting—this crucial step helps everything set up so your slices hold together instead of falling apart. Garnish with fresh chopped cilantro and serve with your favorite toppings. If you can wait that long, dig in and enjoy this layered perfection.

Notes:

• Don’t drain the diced tomatoes—that juice keeps everything moist during baking
• Slight overlapping of tortillas prevents dry spots where filling shows through
• The resting time after baking is crucial for clean, neat slices that hold together
• Covering with foil for the first 25 minutes steams the tortillas so they soften properly
• Taste and season the filling boldly before layering—this is your only chance

Storage Tips:

Refrigerator: Store covered for up to 4 days. Reheat individual portions in the microwave or the whole casserole covered with foil at 350°F for 20-25 minutes until heated through.

Freezer: Freeze the assembled unbaked casserole tightly wrapped in plastic wrap then foil for up to 3 months, or freeze baked leftovers for up to 2 months. Thaw overnight in the refrigerator before baking or reheating.

Make-Ahead: Assemble completely up to 24 hours ahead, cover tightly, and refrigerate. Add 10 minutes to the covered baking time since it’s starting cold.

Serving Suggestions:

• Complete meal: Serve with Mexican rice and refried beans for the full enchilada plate experience
• Fresh toppings: Top with sour cream, diced avocado, sliced jalapeños, and fresh salsa
• Light side: Pair with a simple green salad with lime vinaigrette to balance the richness
• Festive spread: Make it the centerpiece of Taco Tuesday with chips, guacamole, and margaritas

Mix It Up (Recipe Variations):

Chicken Enchilada Casserole: Substitute 3 cups shredded rotisserie chicken for ground beef—just mix with the cooked vegetables, no browning needed.

Extra Spicy: Add diced jalapeños with the vegetables and use pepper jack cheese instead of Mexican blend for serious heat.

White Enchilada Casserole: Make a quick sauce with 1 cup sour cream, 1 can green enchilada sauce, and cumin, then layer like lasagna for creamy white version.

Vegetarian: Skip the meat entirely and double the beans, adding diced zucchini and extra bell peppers for a hearty meatless version.
