Your new go-to for busy nights! This cheesy, layered casserole is like a taco and a lasagna rolled into one easy, crowd-pleasing dish. It’s pure comfort food that’s ready in about 30 minutes.

Ingredients

Scale
  • 1 lb ground beef (85/15 lean is great)
  • 2 tbsp taco seasoning
  • 1 can (15 oz) chili beans (do not drain)
  • 1 can (10 oz) Rotel (diced tomatoes & green chilies)
  • 1 can (15 oz) crushed tomatoes
  • 1216 corn tortillas, cut into quarters
  • 1 cup sour cream
  • 2 cups shredded Cheddar cheese (shred your own for the best melt!)

Instructions

  1. Prep: Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch casserole dish.
  2. Cook Beef: In a large skillet over medium-high heat, brown the ground beef, breaking it apart as it cooks. Drain off any excess grease.
  3. Make Filling: Reduce heat to medium. Stir in the taco seasoning, followed by the undrained chili beans, Rotel, and crushed tomatoes. Let the mixture simmer for 5 minutes to allow the flavors to combine.
  4. First Layer: Arrange a single, overlapping layer of quartered tortillas on the bottom of your prepared dish. Top with half of the beef mixture.
  5. Second Layer: Sprinkle 1 cup of the shredded cheese over the beef. Top with another layer of tortillas.
  6. Final Layer: Spread the remaining beef mixture over the tortillas. Spoon the sour cream on top and gently spread it into an even layer.
  7. Bake: Top with the remaining 1 cup of cheese and bake for 20 minutes, or until the cheese is melted and bubbly. Let it rest for 5 minutes before serving.

Notes

  • Serving Suggestions: This dish is fantastic on its own or topped with guacamole, fresh cilantro, or a dollop of sour cream. Serve with a side of tortilla chips or a simple green salad.
  • Pro Tip: For the best texture, don’t skip the cheese layer in the middle! It separates the tortilla layers and creates a delicious, cheesy center.
  • Storage & Reheating: Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave or the entire casserole in a 350°F oven until warmed through. This recipe also freezes beautifully before baking.
