Step by Step Instructions
- Prepare Your Oven and Dish:
- Heat your oven to three hundred fifty degrees Fahrenheit Spray your baking dish lightly to prevent sticking and set aside
- Cook the Meat and Onion:
- In a large skillet combine ground beef and diced onion Cook gently over medium heat stirring often until the beef loses its pink color and the onion softens Fully cooking at this stage helps everything meld later
- Add Garlic and Seasoning:
- Stir in the minced garlic letting it sizzle and release aroma for about a minute Sprinkle in taco seasoning then pour in water Stir very well so each bit of meat is coated and the flavors begin to soak
- Mix in Beans and Tomatoes:
- Pour in the diced tomatoes with all their juice plus the green chiles and black beans Stir to blend evenly Heat through until the mix is bubbling slightly letting the tomatoes infuse the meat
- Layer the Casserole:
- Arrange six corn tortillas in the bottom of the prepared dish overlapping to make a complete layer Top with one third of your meat mixture then scatter two cups of cheese over everything Repeat this layering twice more for three total layers ensuring even coverage each time
- Bake:
- Cover your casserole snugly with aluminum foil Transfer to the oven and bake thirty to forty minutes until bubbly and the cheese is thoroughly melted This gentle bake allows flavors to mingle
- Rest and Serve:
- Remove from the oven but let the casserole sit uncovered for ten full minutes before cutting This rest time firms up the layers making clean slices Top with diced tomatoes and green onions and dollop each serving with sour cream
