This easy nacho casserole recipe is a cheesy, hearty, family-friendly dinner loaded with seasoned ground beef, crunchy tortilla chips, melty cheese, and classic taco-inspired flavors. Perfect for busy weeknights, potlucks, or comfort food cravings, this homemade nacho bake is a fun and satisfying meal everyone will love.
Start by heating a large frying pan over medium heat and sautéing the diced onions for about 8 minutes until they become soft, translucent, and lightly golden. Once the onions are softened, add the minced garlic and cook for another minute until fragrant. This flavorful base creates rich depth for your easy nacho casserole recipe. Add the lean ground beef to the pan, then season it generously with salt, black pepper, paprika, and chili flakes. Cook the beef thoroughly, breaking it apart as it browns, until fully cooked through and packed with bold Tex-Mex flavor.
Once the beef is fully cooked, stir in the diced orange pepper, corn, salsa, tomato sauce, jalapeños, and black beans. Mix everything together well and also allow the mixture to heat through completely. This hearty combination creates the perfect cheesy, savory filling for this homemade nacho bake, loaded with texture, spice, and classic nacho-inspired ingredients.
Preheat your oven to 400°F (200°C) and prepare a 9×13 baking dish. Begin layering the casserole by spreading half of the tortilla chips evenly across the bottom of the dish. Top with half of the seasoned beef mixture, followed by a generous layer of shredded cheese. Repeat with a second layer of tortilla chips, beef mixture, and cheese, creating a hearty, satisfying layered casserole. This method ensures every bite of your loaded nacho casserole is packed with crunchy chips, seasoned beef, and gooey melted cheese.
Place the casserole into the oven and bake for about 20 minutes, or until the cheese is fully melted and the beef mixture is bubbling around the edges. Once baked, remove it from the oven and top with freshly diced spring onions for added flavor and freshness. Serve warm with extra tortilla chips, guacamole, sour cream, or your favorite nacho toppings. This family-friendly nacho casserole is perfect for weeknight dinners, potlucks, game day meals, or easy comfort food.
