What’s in Tortilla Chip Casserole?

Fritos corn chips are the star of this delicious baked casserole recipe! They make it a super crunchy and fun variation of your average Mexican-style casserole. 

  • Olive Oil: Used for sautéing the onions and garlic, adding flavor and helping to cook them evenly.
  • White Onion: Provides a savory and slightly sweet flavor to the dish. It adds depth and aroma to the casserole.
  • Garlic: Adds a rich and aromatic flavor to the dish. It enhances the overall taste and complements the other ingredients.
  • Cumin + Chili Powder: These spices contribute a warm and earthy flavor with a hint of smokiness. They are commonly used in Mexican cuisine and provide a traditional taste to the casserole.
  • Black Beans: They add protein, fiber, and a creamy texture to the dish. Black beans also contribute to the overall heartiness of the casserole.
  • Corn: Adds a touch of sweetness, texture, and color to the casserole. It complements the other ingredients and adds a burst of freshness.
  • Diced Green Chilies: These provide a mild to medium level of heat and add a slight tangy flavor. They enhance the overall taste and give a nice kick to the casserole.
  • Cooked Chicken: Adds protein and substance to the dish. I like to use shredded chicken.
  • Cream of Chicken Soup: Creates a creamy and rich texture while adding flavor to the casserole. It serves as a binding agent and helps to create a cohesive dish.
  • Rotel: Adds a spicy kick and tanginess to the casserole, providing a burst of flavor.
  • Sour Cream: Adds creaminess and tanginess to the casserole. It helps to balance the flavors and provides a smooth texture.
  • Cream Cheese: Contributes to the creamy and rich consistency of the casserole. It adds depth of flavor and richness.
  • Fritos: These corn chips provide a crunchy and savory texture to the casserole. They add a fun element and are often used as a topping.
  • Mexican Cheese Blend: Typically a mixture of cheeses like cheddar, Monterey Jack, and/or queso quesadilla. It melts well and adds a cheesy, gooey element to the casserole.
  • Cilantro: Adds a fresh and herbaceous flavor to the dish. It serves as a garnish and provides a pop of green color. The flavor of cilantro can vary, and some people may choose to omit it if they don’t enjoy the taste.

Pro Tip: Feel free to increase or reduce the amount of chili powder based on your spice preferences.

Variations on Corn Chip Casserole

This casserole is easy to customize to your personal tastes.

  • For a spicier casserole, add some diced jalapeños. You could also double up on the diced green chilies for a more pronounced flavor.
  • For a milder casserole, you can swap out the Rotel for a can of diced tomatoes and add diced bell peppers.
  • For a vegetarian casserole, omit the chicken and add extra veggies, like zucchini or bell peppers. Use vegetable broth instead of chicken broth, and use cream of mushroom. or cream of celery soup instead of cream of chicken.
  • Take this casserole up a notch by using BBQ shredded chicken, and swap out the Mexican cheese for cheddar. Yum!

What is Frito casserole?

Frito casserole is a hearty casserole consisting of sautéed onions, garlic, and Mexican spices mixed with corn, beans, green chilies, Fritos, and shredded chicken in a creamy, cheesy sauce.

Can I make Frito casserole with a different kind of corn chip?

Absolutely! Feel free to use Doritos or tortilla chips instead of Fritos.

How can I make Frito casserole less spicy?

There are quite a few opportunities to reduce (or increase!) the spice in this recipe. First, you can reduce the amount of chili powder down to as low as ⅛ teaspoon. You can also choose to omit the spicy diced green chilies. Finally, you can choose the original Rotel or Rotel Hot to play with the spice even more. If original Rotel is too hot for you, simply sub in diced tomatoes!

How to Make Ahead and Store

You can make this dish without the Fritos up to 1 day in advance and then assemble as you serve. Store the casserole tightly wrapped in plastic wrap in the refrigerator until ready to serve. Just put a handful of Fritos on the plate and serve a large spoon of the casserole over the Fritos.

Store leftover Frito casserole in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F oven for 10-15 minutes or in the microwave for 30-60 seconds, until hot.

How to Freeze and Reheat

Freeze Frito casserole baked or unbaked tightly wrapped in 2 layers of plastic wrap and 1 layer of aluminum foil for up to 3 months. If frozen baked, let thaw overnight in the refrigerator before reheating. If frozen unbaked, bake directly from frozen in a 350°F oven for about 50-60 minutes.

Serving Suggestions

This casserole pairs perfectly with rice, roasted veggies, salsa or guacamole, cornbread, or a fresh Southwest salad.
