This Walking Taco Casserole brings together all the fun of classic walking tacos in a hearty, family-friendly dish! With layers of seasoned beef, crunchy Fritos, gooey cheese, and your favorite toppings, it's an easy, customizable meal that's perfect for any weeknight or party.
In a skillet cook the chopped onion and ground beef over medium-high heat until no longer pink. Add the green chilies, salsa, taco seasoning, and sour cream to the beef, stirring until combined.
Spray a 9x13 baking dish with nonstick spray and add a layer of Fritos. Top the chips with the meat mixture then sprinkle the shredded cheese on top.
Bake the casserole at 350 degrees for 15-20 minutes or until the cheese is melted.
Remove from the oven and top individual servings with shredded lettuce, diced tomatoes, salsa, and sour cream.
