Frito Pie Casserole just took your ordinary bag of Fritos to the land of deeply delicious, where everyone who asks “What’s for dinner” walks away with a smile on their face.

I guess you could sort of also describe it as a taco casserole, but that does not do it justice. Because those Fritos make it more like a party in a casserole dish.

Easy and quick Frito casserole

With easy Frito Pie Casserole, you essentially prepare a super easy chili to layer in with the Fritos, and of course add a layer of cheese to melt in too. The dish is mostly cooked in a pan, then baked just long enough to set everything up and melt that cheese layer.

Can I make it ahead of time?

If you want to make a Frito casserole ahead of time, then no problem. Go ahead and make all the layers except for the last top layer of cheese and Fritos. Adding those right before going into the oven keeps your Fritos on top nice and crunchy.

Can I freeze a Frito pie casserole?

Storing Frito casserole in the freezer to serve later is ok. You can store it for up to 30 days like that. However, I recommend adding a layer of fresh Fritos and more shredded cheese on top when you reheat it.

How to reheat

You can reheat the frito pie casserole from the fridge or if it is frozen a few ways.

  • Use a microwave safe dish and heat on a medium setting for about a minute and half if not frozen. For frozen, you need about five minutes depending on the size of the piece, but make sure to give a half turn to it about halfway through.
  • Reheating it in the oven is best. That helps restore the crunch to the Fritos, but you can also add fresh Fritos and more cheese too.
  • You can use a frying pan to heat up your leftovers too. Another way to sneak in more cheese and Fritos too.

What are ranch style beans?

Ranch style beans are beans that are typically seasoned with taco seasoning blends. Those seasonings include cumin, some chili powder, smoky paprika, garlic powder, and salt and pepper.

If you don’t have seasoned ranch style beans handy, then you can season some pinto beans (and even seasoned black beans) as well.

Storage:

For the refrigerator or the freezer, store in an airtight container. In the fridge, you can store it up to a few days, and in the freezer you can store it for about a month.

My only recommendation is to use some fresh Fritos and a bit more shredded cheese for the top when you reheat it. That way you capture all the fun of when it was first served.

Best Casserole Tips

  • You can easily make this ahead of time but save adding the last layer of Fritos and cheese for just before it goes in the oven. That keeps the crunch in the chips best.
  • If the meat is too soupy after you cook it and and the other ingredients, then drain a bit more of the liquid first. Baking the frito pie casserole tightens everything up though, so don’t take out too much liquid, just a quarter or half cup at most.
  • Let the melted cheese on top be your guide to doneness. Since all the ingredients are cooked ahead of adding it into the casserole dish, you are just looking for the cheese to melt and slightly brown those Fritos on top.
  • Use a proper casserole dish, glass or enamel ones are best but tin will do too. The larger the casserole dish, the more quickly it cooks.
  • Spraying some cooking oil on the inside of the baking dish makes clean up after serving a lot easier. Just a light coat to prevent sticking. You don’t need to deep fry it in lots of extra oil.
