How to Make Tex Mex Casserole

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

Step 2: Cook the Beef

Heat a skillet over medium-high heat. Add ground beef, breaking it apart as it cooks. Season with salt and pepper. Cook for about 5–7 minutes until browned. Drain excess fat and set beef aside.

Step 3: Sauté Aromatics

In the same skillet, add diced onion and cook for 3–5 minutes until softened. Stir in minced garlic and cook for about 60 seconds until fragrant.

Step 4: Build the Base

Return the cooked beef to the skillet. Add tomato paste, chopped tomatoes, and salsa. Stir well to combine into a rich, flavorful mixture.

Step 5: Add Beans and Rice

Mix in black beans and cooked basmati rice. Stir until everything is evenly combined and coated in sauce.

Step 6: Assemble the Casserole

Transfer the mixture into the prepared baking dish. Spread evenly, then top with shredded cheddar cheese. Sprinkle diced green bell pepper over the top.

Step 7: Bake and Finish

Bake uncovered for 25 minutes. Then broil for 2–3 minutes until the cheese is golden and bubbly.
