What Ingredients are in Fiesta Fritos Casserole?
This crowd-pleasing casserole requires just a handful of simple ingredients that you probably already have in your pantry or can easily grab at the grocery store.
- 1 lb ground beef
- 1 can corn, drained
- 1 can Rotel tomatoes
- 1 packet taco seasoning
- 2 cups shredded cheddar cheese
- 1 bag Fritos corn chips
- 1 can cream of chicken soup
- 1/2 cup sour cream
For serving, you might want to keep extra sour cream and some diced green onions on hand as optional toppings, which add a nice cool creaminess and fresh bite to balance the rich, spicy flavors of the casserole.
How to Make this Fiesta Fritos Casserole
Step 1: Brown the Ground Beef
Start by browning 1 pound of ground beef in a large skillet over medium heat, breaking it up with a spoon as it cooks.
Once fully browned, drain off the excess fat—nobody wants a greasy casserole, right?
Step 2: Mix in the Seasonings and Wet Ingredients
Add the packet of taco seasoning to your beef and stir well.
Then mix in the can of Rotel tomatoes (undrained for extra flavor), drained can of corn, cream of chicken soup, and 1/2 cup of sour cream until everything is beautifully combined.
Step 3: Prepare Your Baking Dish
Grab a 9×13 baking dish and get ready for the layering magic.
This is where our casserole starts to take shape, transforming from ingredients to dinner masterpiece.
For dessert after your casserole, consider using a premium brownie set to create the perfect sweet ending to your meal.
Step 4: Create the First Layer
Spread half of your Fritos corn chips across the bottom of the dish, creating a crunchy foundation.
Those little corn chips will soak up some of the flavors while still maintaining a bit of their crunch.
Step 5: Add the Meat Mixture
Spoon your seasoned beef mixture evenly over the Fritos layer.
Make sure to spread it all the way to the edges so every bite has that delicious, savory goodness.
Step 6: Top with Cheese and More Fritos
Sprinkle 2 cups of shredded cheddar cheese over the meat mixture, then top with the remaining Fritos.
The cheese forms that gooey middle layer that holds everything together, while the Fritos on top will get perfectly toasty.
Step 7: Bake to Bubbly Perfection
Pop your casserole into a preheated 350°F oven and bake for 25-30 minutes, or until the cheese is melted and the edges are bubbling.
The kitchen will smell amazing, and you might notice family members mysteriously appearing nearby.
Step 8: Serve with Optional Toppings
Let the casserole rest for about 5 minutes before serving.
For the full experience, offer additional sour cream and diced green onions at the table.
These cool, fresh toppings balance the warm, spicy casserole perfectly.
What to Serve with Fiesta Fritos Casserole
This hearty casserole is a complete dinner star on its own, but a few simple sides can turn it into a proper fiesta!
A crisp green salad with lime vinaigrette cuts through the richness perfectly, while some Mexican street corn (elotes) brings complementary flavors without doubling up on the corn already in the dish.
For beverages, try ice-cold horchata or a tangy margarita for the adults at the table.
I love setting out small bowls of diced avocado, fresh cilantro, and lime wedges so everyone can customize their plate.
And don’t forget warm flour tortillas on the side—they’re perfect for scooping up any stray bits of that cheesy goodness that might escape your fork!
Fiesta Fritos Casserole Substitutions and Variations
- Swap ground beef for ground turkey, chicken, or even plant-based crumbles for a lighter option.
- Make it dairy-free by using dairy-free cheese and coconut cream instead of sour cream.
- No Rotel? Use regular diced tomatoes with a dash of hot sauce or diced jalapeños.
- Try crushed tortilla chips or Doritos instead of Fritos for a different crunch.
- Add a can of black beans or pinto beans for extra protein and fiber.
- Spice it up with a teaspoon of cumin, chili powder, or chipotle powder.
- Create a breakfast version by adding scrambled eggs to the mixture.
- Top with sliced black olives, diced red onion, or fresh jalapeños for extra zing.
- Cream of mushroom soup works beautifully if you’re out of cream of chicken.
- For a fresh twist, fold in chopped cilantro and a squeeze of lime juice just before serving.
- Microwave individual portions for 1-2 minutes, stirring halfway
- Or reheat in a 325°F oven for about 15 minutes to help crisp it back up
- Add a sprinkle of fresh Fritos just before serving for renewed crunch
Leftovers and Storage for this Fiesta Fritos Casserole
This casserole transforms wonderfully into next-day lunch options, though the Fritos will naturally soften over time.
Store leftovers in an airtight container in the refrigerator for up to 3 days—any longer and those textures really start to merge (not always in a good way).
For best results when reheating:
Want to freeze? The base mixture freezes beautifully for up to 2 months, but add fresh Fritos and cheese when reheating for the best texture.
I’ve found the flavors actually deepen overnight, making day-two servings sometimes even more flavorful than the first round.
