Step-by-Step Cooking Instructions

Step 1: Prepare Your Ingredients
Start by gathering and preparing all your ingredients. Dice the onion and garlic, measure out the spices, and drain and rinse the beans and corn. Preheat your oven to 375°F (190°C).
Step 2: Cook the Ground Meat
In a large skillet, heat the olive oil over medium heat. Add the ground beef (or turkey) and cook until browned, breaking it up with a spoon as it cooks. Drain any excess fat from the skillet.
Step 3: Sauté the Vegetables
Add the diced onion to the skillet with the cooked meat. Sauté for about 5 minutes, until the onion is softened. Add the minced garlic and cook for another minute until fragrant.
Step 4: Add the Beans, Corn, and Spices
Stir in the black beans, corn, diced tomatoes with green chilies, tomato sauce, salsa, taco seasoning mix, ground cumin, chili powder, salt, and pepper. Mix everything together until well combined and heated through.
Step 5: Layer the Casserole
In a greased 9x13-inch casserole dish, spread a thin layer of the meat and vegetable mixture. Place a layer of tortillas on top, followed by more of the meat mixture and a layer of cheese. Repeat the layers, ending with a generous layer of cheese on top.
Step 6: Bake the Casserole
Cover the casserole dish with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbly.
Step 7: Garnish and Serve
Remove the casserole from the oven and let it sit for a few minutes before serving. Garnish with chopped fresh cilantro if desired. Serve hot with sour cream and sliced jalapeños on the side.
How to Cook Tex-Mex Casserole: A Step-by-Step Guide
Making Tex-Mex casserole is easy if you follow these detailed steps:
- Brown the Meat: Ensure the ground meat is fully browned and crumbled before adding the vegetables.
- Sauté the Vegetables: Cook the vegetables until they are tender but not mushy to retain some texture.
- Combine Ingredients Thoroughly: Mix all ingredients well to ensure even distribution of flavors.
- Layer Carefully: Layering the ingredients ensures that each bite has a balanced mix of flavors and textures.

- Not Letting it Rest: Allow the casserole to rest for a few minutes after baking to set and make serving easier.
