Step-by-Step Instructions: How to Make Ground Beef Taco Casserole
Preparation:
- Preheat the oven to 350°F (175°C).
- Grease a 9×13-inch baking dish with a little olive oil or cooking spray, then set it aside.
Cooking the Base:
- In a large skillet, heat 1 tablespoon of olive oil over medium-high heat.
- Add the ground beef and cook it, breaking it up with a spatula, until it’s browned and cooked through, about 6-8 minutes.
- Transfer the beef to a plate using a slotted spoon, and drain the excess fat from the skillet.
- Reduce the heat to medium, then add the remaining 1 tablespoon of olive oil to the skillet. Once the oil is shimmering, add the onion, red bell pepper, and garlic. Sauté, stirring occasionally, until the vegetables are tender, about 5 minutes.
- Return the cooked ground beef to the skillet. Stir in the pinto beans, tomato paste, chili powder, ground cumin, oregano, kosher salt, and black pepper. Stir everything together and cook for 2 more minutes to let the flavors combine.
- Remove the skillet from the heat and stir in salsa and 3/4 cup of shredded cheese.
Baking and Serving

- Transfer the meat and bean mixture into the prepared baking dish, spreading it evenly.
- Sprinkle the remaining 3/4 cup of cheese over the top.
- Bake in the preheated oven for about 20 minutes, or until the cheese is melted and bubbly.
- Let the casserole sit for 5 minutes before serving.
- Top the casserole with chopped romaine lettuce and diced tomato. Serve with a dollop of Greek yogurt or sour cream on top.

When ready to serve, bake it as directed, adding a few extra minutes if needed to ensure it’s warmed through.
2. Can I substitute the ground beef with another type of meat?
Absolutely! If you prefer a different protein, you can swap the ground beef for ground turkey, chicken, or even a plant-based meat alternative for a vegetarian version. The seasonings in the recipe work well with a variety of proteins, so feel free to adjust based on your preference.
