Taco Doritos Casserole is the ultimate comfort food to bring excitement to a weeknight dinner. With layers of seasoned ground beef, sweet corn, creamy cheese, and crunchy Doritos, this dish becomes a crave-worthy classic. A hint of spice from taco seasoning and green chiles brings it all together, making every bite loaded with bold flavor and texture.
When I served this for a movie night my family polished off the whole casserole before we could even decide on what to watch Everyone raved about how fun and filling it was
Ingredients
- Lean ground beef: Adds protein and absorbs all those taco spices Choose eighty five to ninety percent lean for the best balance of flavor and less grease
- Yellow onion: Gives a sweet and mellow base Select onions that feel firm with dry skin
- Minced garlic: Infuses aromatic punch Use fresh for the boldest flavor
- Taco seasoning: Brings all the classic taco flavors from chili to cumin Opt for your favorite brand or homemade blend if you like more control over the spice level
- Frozen corn: Brings sweetness and a pop of texture Pick bright yellow kernels with no ice crystals for freshness
- Petite diced tomatoes with green chilies: Deliver mild heat and savory tang Choose brands without heavy additives for the best taste
- Sour cream: Makes the filling creamy and tangy Full fat is best for the richest casserole
- Crushed Doritos: Give layers of crunch and cheesy flavor Use nacho cheese flavor and crush by hand for a mix of fine and chunky bits
- Mexican blend cheese: Brings meltiness and extra richness Pre shredded works but shredding your own gives the best melt
- Black beans: Optional for extra heartiness Choose canned beans drained and rinsed for convenience
- Garnishes: Like green onions diced tomatoes lettuce avocado and extra sour cream add freshness and color Use whatever is in season or on hand
Step by Step Instructions
- Preheat the Oven:
- Set your oven to three hundred fifty degrees and let it heat while you prep the ingredients This ensures even baking
- Prepare the Doritos:
- Gently crush the chips in a large bag Two cups should be smashed fine like breadcrumbs This helps soak up flavor in the filling Keep one cup in bigger chunks for that crunchy topping at the end
- Cook the Beef and Onions:
- Heat a large skillet over medium Cook the ground beef and chopped onions slowly until beef is browned and onions soften about eight minutes Drain off any extra grease to keep the casserole from getting soggy
- Add the Flavor Makers:
- Stir in minced garlic and sauté for another minute to let it bloom Toss in the frozen corn taco seasoning tomatoes with green chilies and two cups of the finely crushed Doritos Stir it all to combine and warm everything through
- Creamy Mix In:
- Remove skillet from heat Fold in the sour cream and two cups of Mexican blend cheese until everything is evenly combined Sour cream melts and adds creaminess while cheese ensures every bite is gooey
- Assemble and Bake the Casserole:
- Coat a nine by thirteen casserole dish with nonstick spray Pour in the meat and veggie mixture and spread evenly Bake for five minutes just to heat it through This step fuses all the flavors
- Cheesy and Crunchy Topping:
- After five minutes open your oven Sprinkle the remaining one cup of cheese and scatter one cup of the loosely crushed Doritos over the top Return to oven for five more minutes This melts the cheese and creates a golden crust
- Serve and Garnish:
- Remove from oven Let cool slightly then serve hot For freshness top each portion with green onions diced tomatoes lettuce avocado and an extra dollop of sour cream if desired

My favorite part is the mix of textures especially those chunky Dorito pieces on top They remind me of childhood family gatherings when my cousins and I would sneak extra chips onto our plates and fight over the last crunchy bits
Storage Tips
Wrap leftovers tightly in foil or move to an airtight container The casserole keeps well in the fridge for up to three days For longer storage freeze portions and reheat in the oven to keep the topping crisp I love doubling the recipe and freezing half for lazy weeknights
Ingredient Substitutions
You can make this with ground turkey or even a vegetarian meatless crumble for a lighter result Swap the Mexican blend cheese for cheddar or pepper jack if you want more kick If you avoid corn use a mix of red peppers and peas for another layer of sweetness
