Ingredients

This recipe makes 6 servings in a 9-by-13-inch baking dish.

• 1 tablespoon olive oil
• 1 1/2 pounds lean ground beef
• 1 medium yellow onion, diced
• 2 garlic cloves, minced
• 2 tablespoons tomato paste
• 1 packet taco seasoning, or 2 tablespoons homemade seasoning
• 1 cup salsa
• 1 can black beans, 15 ounces, drained and rinsed
• 1 cup frozen corn
• 1/2 cup beef broth or water
• 1 1/2 cups shredded cheddar or Mexican-blend cheese
• 4 cups corn chips, such as plain tortilla chips or snack-size corn chips
• 1 cup shredded lettuce
• 1 cup diced tomatoes
• 1/2 cup sour cream
• 1/2 cup guacamole or sliced avocado
• 1/4 cup chopped cilantro or green onions
• Lime wedges and hot sauce, for serving

Choose a chunky salsa if you like pieces of tomato and pepper in the filling. A smooth salsa creates a softer, more cohesive casserole. For extra heat, use a spicy salsa or add one diced jalapeño with the onion.

How to Make It Step by Step

1. Heat the oven. Set the oven to 375°F and grease a 9-by-13-inch baking dish. Keep the corn chips out of the oven so they stay crunchy for serving.
2. Brown the beef. Heat the olive oil in a large skillet over medium-high heat. Add the beef and cook for 6 to 8 minutes, breaking it into small crumbles, until no pink remains. Drain excess grease if needed.
3. Add the aromatics. Stir in the onion and cook for 3 to 4 minutes, until softened. Add the garlic and tomato paste and cook for 1 minute. The tomato paste should darken slightly and coat the beef.
4. Simmer the filling. Stir in the taco seasoning, salsa, black beans, corn, and broth. Reduce the heat to medium-low and simmer for 8 to 10 minutes, stirring occasionally, until thick and spoonable. Taste and add salt only if needed.
5. Layer the casserole. Spread the beef mixture in the baking dish. Sprinkle the shredded cheese evenly over the top. Bake for 15 to 18 minutes, until the cheese is melted and the edges are bubbling.
6. Rest briefly. Let the casserole stand for 5 minutes. This gives the filling time to settle and makes it easier to scoop without leaving a watery layer in the dish.
7. Serve walking-taco style. Spoon the hot filling into bowls, then add a handful of corn chips, lettuce, tomatoes, sour cream, guacamole, cilantro, lime, and hot sauce. Serve immediately.

Tips and Variations

Keep the chips crunchy

Do not mix the corn chips into the casserole before baking. They absorb moisture and lose their signature crunch. Put them on the table in a bowl or add them to each serving just before eating. If you are packing lunches, keep the chips in a separate small bag.

Make it with another protein

Ground turkey, shredded chicken, or leftover pulled pork all work well. For a vegetarian version, replace the beef with another can of beans and 1 cup chopped mushrooms. Cook the mushrooms until their moisture evaporates, then continue with the salsa and seasoning.

Add more vegetables

Stir in diced bell pepper with the onion, or add chopped zucchini, roasted poblanos, or spinach to the skillet. Keep the mixture thick by cooking watery vegetables until their liquid has evaporated before adding the salsa.

Set up a topping bar

Arrange toppings in small bowls so everyone can build their own serving. Add easy guacamole, fresh lime, jalapeños, shredded cheese, pickled onions, and cilantro. For another hearty Mexican-inspired option, serve a cup of easy taco soup alongside the casserole. Layered Mexican dip makes a fun starter, while comforting tater tot casserole is a good alternative for a different kind of family night.

Storage and Reheating

Store the cooked filling and toppings separately in airtight containers. Refrigerate the casserole for up to 4 days. Keep corn chips sealed at room temperature. Reheat the filling in a covered skillet over medium-low heat, adding a splash of broth if it has thickened, or microwave it in 60-second intervals.

Freeze the filling before adding cheese for up to 2 months. Thaw it overnight in the refrigerator, spread it in a baking dish, top with fresh cheese, and bake at 375°F until hot and bubbling. Fresh chips and toppings should always be added after reheating. Ground beef should be cooked thoroughly; the USDA lists 160°F as the safe minimum internal temperature for ground meat in its safe temperature chart.

For an even more festive presentation, place the toppings in colorful bowls and let everyone choose a mix of creamy, crunchy, and fresh ingredients. A squeeze of lime just before eating keeps the savory filling lively. If you are serving children, offer plain cheese, mild salsa, and sour cream first, then keep the spicy toppings on the side for adults.

Leftover filling also makes a quick lunch: spoon it over rice, fold it into a quesadilla, or pile it onto baked potatoes. Add a little shredded cheese while reheating so the mixture becomes creamy again.

Frequently Asked Questions

What is a walking taco casserole with corn chips?

It is a baked taco filling served with crunchy corn chips and fresh toppings, inspired by walking tacos that are assembled directly in a chip bag. Baking the filling separately makes it easier to serve to a family or a crowd.

Can I add the corn chips before baking?

You can sprinkle a small amount over the cheese for a toasted topping, but most of the chips should be added after baking. That keeps them crunchy instead of soft.

Can I make this casserole ahead of time?

Yes. Cook the filling up to 2 days ahead and refrigerate it. Spread it in the baking dish, add the cheese, and bake when you are ready. Add about 5 extra minutes if the mixture is cold from the refrigerator.

How do I make it less spicy?

Use mild salsa and taco seasoning, skip the jalapeños, and serve hot sauce on the side. Sour cream, avocado, and shredded lettuce also soften the heat in each bite.

Can I make it gluten-free?

Use certified gluten-free taco seasoning and corn chips, then check the labels on salsa, broth, and any packaged toppings. The basic beef, bean, vegetable, and cheese ingredients are naturally gluten-free, but packaged seasonings can vary.
