How to Make Walking Taco Casserole (Step-by-Step)

Step 1: Brown the Beef

In a large skillet over medium heat, cook 1 lb of ground beef, breaking it apart with a wooden spoon until browned and no longer pink. Drain excess fat.

Step 2: Add Seasoning & Ro-Tel

Add 1 packet taco seasoning and 1 can of Ro-Tel (undrained) to the beef. Stir to coat evenly. Let it simmer for 5 minutes to allow the flavors to meld and moisture to reduce slightly.

Step 3: Layer the Casserole

In a 9×13-inch baking dish:

Spread half the Fritos across the bottom.
Add half of the beef mixture on top.
Sprinkle half the cheese over the meat.
Repeat: remaining Fritos → beef mixture → cheese.

Pro Tip: Use a light hand with the chips on the bottom layer to avoid sogginess. Save a handful to sprinkle on after baking for added crunch.

Step 4: Bake

Preheat oven to 350°F (175°C).
Bake uncovered for 15–20 minutes, or until the cheese is melted, bubbly, and golden around the edges.

Step 5: Top and Serve

Immediately after baking, top with:

Shredded lettuce
Diced tomatoes
Onions (raw or sautéed)
And any additional toppings you love

Serve hot and let the fiesta begin!

Recipe Tips & Variations

Customize Your Crunch

Fritos work best for classic flavor.
Try Doritos, Tostitos, or tortilla strips for a fun twist.
To avoid sogginess, sprinkle some fresh chips on top after baking.

Cheese Choices

Freshly grated cheese melts better than pre-shredded (which has anti-caking agents).
Mix cheddar with Monterey Jack, Pepper Jack, or Queso Blanco for extra flavor.

Add More Heat

Add a dash of cayenne to the beef mix.
Stir chipotle peppers in adobo into the Ro-Tel layer.
Swap cheddar for spicy Pepper Jack.

Add More Nutrition

Stir in black beans, frozen corn, or diced bell peppers for extra fiber and color.
Use ground turkey or plant-based meat as a leaner alternative.

Serving Suggestions

Plate the casserole as-is or serve with extra chips for scooping.
Pair with Mexican rice, refried beans, or street corn salad.
Hosting a party? Turn it into a dip by skipping the lettuce and serving with tortilla chips.
Storage & Reheating

Refrigeration:

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

Reheating:

Microwave individual portions for 1–2 minutes.
Oven method: Reheat at 300°F for 10–15 minutes to restore some crunch.

Freezer?

Best enjoyed fresh. If freezing, do so before baking and without toppings.
