When the craving for something cheesy and crowd-pleasing hits, this Dorito Taco Casserole is the answer. With layers of zesty taco meat, crunchy Doritos, and melty cheese all baked until bubbly, it has never failed to get rave reviews at gatherings or family dinners in my home.

I first made this casserole for a Friday game night and was amazed at how quickly it disappeared. Now it is always requested for birthday parties and makes weeknights feel a little more festive.

Ingredients

  • Ground beef: Choose a fresh and vibrant red beef with a little fat marbling for max flavor
  • Yellow onion: Adds a sweet foundation Always select onions that feel heavy and firm with no green shoots
  • Minced garlic: Fresh garlic brings a pungent depth and aroma to the dish
  • Taco seasoning: Use your favorite or try a low sodium version for more control over saltiness
  • Rotel: This adds a mild heat and tang so grab a can with diced tomatoes and chilies
  • Mexicorn: Delivers a sweet crunch Opt for cans with the least amount of sodium
  • Taco blend cheese: Shredded cheese melts best when freshly grated at home rather than pre bagged
  • Nacho Cheese Doritos: Provides the signature crunch and cheesiness Look for an unbroken bag to get better layer pieces
  • Toppings like sour cream and Pico de Gallo: Brighten up each bite Select the freshest tomatoes and herbs for your Pico

Step-by-Step Instructions

Prepare the Meat:
Heat the ground beef and diced onions gently in a large skillet over medium high until there are no pink bits left The onions will turn soft and fragrant which makes all the difference
Flavor the Filling:
Sprinkle in the minced garlic and let it bloom in the pan for about half a minute until your kitchen smells incredible Drain off most of the grease but keep a tablespoon or so for flavor
Mix in the Veggies and Seasonings:
Pour in the taco seasoning all of the Rotel including the juices and drained Mexicorn Stir it all together so every bite gets coated with those robust flavors
Layer the Casserole:
In a seven by eleven inch baking dish add half of the beef mixture Next scatter a generous layer of cheese then top with half the crushed Doritos Repeat with the remaining ingredients making sure to end with Doritos and cheese on top
Bake to Perfection:
Place the dish in the center of a preheated 350 degree oven Let it bake for fifteen to twenty minutes until the cheese looks melted and golden and the edges are bubbling
Serve with Toppings:
Fresh Pico de Gallo and big dollops of sour cream go on top right before serving They cool down each bite and add brightness

One of my favorite moments was making this casserole with my kids as they crushed the Doritos with such excitement I love how the Rotel lifts the whole casserole with a subtle tang and spice

Storage Tips

This casserole keeps well in the refrigerator for up to three days Just cover it tightly or transfer to an airtight container Reheat in the oven at 300 degrees to restore some crispness to the Dorito topping For longer storage wrap individual slices well and freeze them for up to a month When reheating from frozen I like to add a little fresh cheese on top to keep it extra melty

Ingredient Substitutions

No Mexicorn on hand Mix regular canned corn with a spoonful of diced red peppers or green chilies Veggie crumbles work fine in place of beef for a vegetarian take For a punchier flavor try going half ground beef and half spicy chorizo You can also swap in Cool Ranch Doritos for a different vibe

Serving Suggestions

Serve this casserole alongside a big green salad with creamy avocado slices or fresh lime wedges A platter of extra Pico de Gallo and sliced jalapeños will let everyone customize their plate For parties I break the casserole into individual ramekins and top each with a little extra cheese before baking for a fun single serving option
