Ingredients

• Ground beef or turkey: choose fresh lean meat for juicy flavor also works wonderfully with ground chicken
• Small onion: gives sweetness and depth pick a firm onion with no bruises
• Garlic: adds punchiness fresh cloves are best but jarred works in a pinch
• Black beans: provide fiber try low-sodium canned versions and rinse well
• Corn kernels: deliver texture and a hint of sweetness fresh or canned both taste great
• Diced tomatoes: use tomatoes with green chilies for a subtle kick
• Taco seasoning: this is your flavor powerhouse make your own for more control over salt and spice
• Shredded Mexican cheese blend: melts beautifully choose from pre-shredded bags or shred your own for best texture
• Salsa: medium or mild brings zest and moisture use a salsa you love to eat with chips
• Corn tortillas: form the hearty casserole base fresh tortillas soak up sauce nicely
• Salt and pepper: fine sea salt and cracked pepper highlight all the other flavors
• Optional toppings: like sour cream avocado cilantro or lime wedges provide cooling creamy or citrusy notes

Step-by-Step Instructions

Preheat Oven:

Place your oven rack in the center and heat to 375 Fahrenheit Set aside a 9 by 13 inch casserole dish lightly greased so nothing sticks this ensures easy serving later

Cook the Filling:

In a large skillet over medium heat crumble and cook the beef or turkey until it is fully browned and no pink spots remain Use a wooden spoon to break it up evenly Scatter in the diced onion and minced garlic then cook for around three minutes stir often until the onion is translucent and the garlic smells fragrant Mix in black beans corn diced tomatoes salsa and taco seasoning Continue stirring and allow the mixture to simmer gently for up to seven minutes or until the mixture reduces and thickens slightly Season with a pinch of salt and a dash of pepper to taste

Layer the Casserole:

Arrange half the tortilla pieces on the bottom of the casserole dish so they overlap and fully cover the dish Pour over half the meat mixture distributing evenly so every bite has beans and veggies Sprinkle one cup of shredded cheese across the top Repeat with the remaining tortillas meat and end with the last cup of cheese so you get beautiful golden bubbles on top

Bake:

Cover your casserole with foil to trap steam and place in the oven Bake for twenty minutes so the flavors meld together and the cheese melts Remove foil and continue baking for an extra ten minutes until the top is golden bubbly and irresistible

Garnish and Serve:

Take the baking dish out of the oven and let it rest on a trivet for around five minutes Fresh garnish choices make the dish pop visually and add vibrant flavor Scatter chopped cilantro arrange a few avocado slices right on top and finish with a generous scoop of sour cream For special occasions I love to serve this on wood boards or colorful plates to keep that festive vibe

Save

My absolute favorite part is the bubbling golden cheese on top The smell takes me straight back to family movie nights when my kids hovered around the oven until I gave the all clear to dig in

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to three days If reheating individual portions microwave them until hot all the way through For best taste use the oven to refresh the entire casserole covered at 350 Fahrenheit until warmed through To freeze let the casserole cool completely then wrap tightly with foil For reheating from frozen bake covered at 350 Fahrenheit until piping hot

Ingredient Substitutions

Feel free to swap ground beef with ground turkey chicken or even plant based crumbles for a vegetarian version Black beans could be exchanged for pinto beans or kidney beans Add extra veggies like bell peppers for more color and nutrition If you choose flour tortillas be aware they will give a softer texture

Serving Suggestions

Offer the casserole with crisp green salad fresh guacamole or a big bowl of pico de gallo Sliced jalapenos or hot sauce bring extra spice Cornbread or tortilla chips pair perfectly for crunch I love setting up a topping bar so everyone can customize their plate with favorites like chopped scallions lime wedges or extra salsa
