Step‑by‑Step Instructions for Easy Taco Casserole
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Easy Taco Casserole bakes evenly and thoroughly. While the oven warms up, take a moment to gather your ingredients and equipment, including a large skillet and a casserole dish.
Step 2: Brown the Meat
In a large skillet over medium heat, add 2 pounds of lean ground beef. As it cooks, use a spatula to break it apart, allowing it to brown evenly, about 7–10 minutes. Once the meat is nearly cooked through, add 2 tablespoons of minced garlic and 1 diced medium white onion, stirring until they soften and become fragrant, about 3–4 minutes more.
Step 3: Combine the Vegetables
In a large casserole dish, combine 2 diced green peppers, 2 diced medium russet potatoes, 3/4 cup of salsa, 1 can of mild green chiles, 1 can of sliced black olives, and 1 can of drained diced tomatoes. Stir the mixture well, ensuring all the vegetables are mixed evenly for a vibrant base that complements the savory meat.
Step 4: Mix in the Beef and Spices
Once the beef is browned and the onion is translucent, drain any excess grease from the skillet. Add the beef mixture into the casserole dish, folding in 2 teaspoons of chili powder, 1.5 teaspoons of cumin, 2 teaspoons of garlic powder, 1 teaspoon of paprika, 1/2 teaspoon of salt, and 1/2 teaspoon of black pepper. Combine thoroughly, ensuring the spices coat the ingredients evenly.
Step 5: Add Bind and Bake
Transfer the mixture back to the casserole dish, and pour in 2 beaten eggs to help bind everything together. Stir until the eggs are distributed throughout the mixture. Cover the dish with foil to keep in moisture, then place it in the preheated oven to bake for 45 minutes to 1 hour, or until the potatoes are tender and cooked through.
Step 6: Serve and Enjoy
Remove the foil during the last 10 minutes of baking for a crispier top, if desired. Once the casserole is done, let it cool slightly before serving. This hearty Easy Taco Casserole is delicious on its own or served on a bed of greens, topped with your favorite toppings like avocado, guacamole, or dairy-free sour cream!

How to Store and Freeze Easy Taco Casserole
