Ingredients

For the Casserole

• 2–3 cups corn chips, such as Fritos
• 1½ lb (680 g) ground beef
• 1 small yellow onion, diced
• 1 packet taco seasoning
• 3 oz (85 g) cream cheese, softened
• 1 can (4 oz) diced green chiles, drained
• 1 cup Mexican-blend shredded cheese

For Topping

• 1–2 cups iceberg lettuce, finely shredded
• 1 Roma tomato, diced
• Sour cream, for serving
• Salsa, for serving

Optional Toppings

• Sliced jalapeños
• Diced avocado
• Green onions
• Black olives
• Pickled onions
• Extra shredded cheese
• Cilantro
• Guacamole

Instructions

1. Preheat the oven

Preheat your oven to 375°F (190°C).

Lightly grease an 8×8-inch or similar 2-quart baking dish.

2. Brown the beef

Place a large skillet over medium-high heat.

Add the ground beef and diced onion. Cook for 6–8 minutes, breaking the beef apart with a wooden spoon, until the beef is browned and the onion is tender.

Drain any excess grease.

3. Season the beef

Return the skillet to the stove over medium heat.

Add the taco seasoning according to the packet directions, usually along with about ¾ cup water.

Stir well and simmer for 3–4 minutes, allowing the seasoning to coat the beef and the mixture to thicken.

4. Make it creamy

Reduce the heat to low.

Add the softened cream cheese and stir until completely melted into the seasoned beef.

Fold in the drained green chiles.

Cook for another 1–2 minutes, until the mixture is creamy and evenly combined.

5. Layer the casserole

Spread about 1 cup of corn chips across the bottom of the prepared baking dish.

Spoon the creamy taco beef mixture evenly over the chips.

Sprinkle the Mexican-blend cheese over the top.

6. Bake

Place the casserole in the preheated oven.

Bake uncovered for 15–20 minutes, until the cheese is completely melted and bubbling around the edges.

7. Add the fresh toppings

Remove the casserole from the oven and let it rest for about 5 minutes.

Scatter the shredded iceberg lettuce and diced Roma tomato over the top.

Drizzle with salsa and add dollops of sour cream.

For the crunchiest result, sprinkle the remaining corn chips over individual servings rather than baking all of them into the casserole.

8. Serve

Scoop generous portions onto plates and serve immediately.

For the full walking taco experience, spoon the hot taco casserole into individual bowls or bags of corn chips and pile on your favorite toppings.

Chef’s Tips

• Keep the lettuce and tomatoes out of the oven. Adding them after baking keeps them fresh and crisp.
• For maximum crunch, reserve some corn chips for topping each serving.
• Soften the cream cheese before adding it so it melts smoothly into the beef.
• If your ground beef is very lean, you may not need to drain it.
• Don’t oversalt the beef—the taco seasoning and cheese already contain plenty of seasoning.
• Let the casserole rest for a few minutes before serving so the layers are easier to scoop.

Easy Variations

Chicken Walking Taco Casserole

Replace the ground beef with 1½ lb shredded cooked chicken. Warm it with the taco seasoning, cream cheese, and green chiles before assembling.

Extra Cheesy

Add another ½–1 cup shredded Mexican-blend cheese and sprinkle some between the beef and the final cheese layer.

Spicy Walking Taco

Add diced jalapeños, hot salsa, or ½ teaspoon cayenne pepper to the beef mixture.

Bean & Beef

Stir 1 can (15 oz) drained black beans or pinto beans into the seasoned beef for extra bulk and fiber.

Loaded Walking Taco

Top individual servings with lettuce, tomato, sour cream, salsa, avocado, jalapeños, olives, cilantro, and crushed corn chips.

Make-Ahead

Prepare the beef mixture up to 1 day ahead and refrigerate it in an airtight container.

When ready to bake, assemble the casserole and bake until heated through and the cheese is melted.

For the best texture, add the corn chips and fresh toppings shortly before serving.

Storage

Refrigerate leftovers in an airtight container for up to 3 days.

The lettuce and other fresh toppings are best stored separately.

Reheating

Reheat the beef and cheese portion in the microwave or a 350°F oven until hot.

Add fresh lettuce, tomato, sour cream, salsa, and crunchy corn chips after reheating.

The Result

You get creamy, cheesy, taco-seasoned beef with a crunchy corn-chip base and fresh, cool toppings in every bite. It’s essentially all the best parts of a walking taco transformed into an easy, scoopable casserole.
