If you have an Instant Pot, I hope you are loving it as much as me. If you don’t have one, I highly recommand getting one this Christmas. Today, I have a recipe for Instant Pot Beef Nacho Casserole.

This meal is seriously ready in 30 minutes. It’s another great Mexican style dinner, so it was a big hit with the family. The actual casserole includes grond beef, onion, taco seasoning, rice, diced tomatoes, corn, and green chilies.

Part of what makes most Mexican dishes delicious is the added topppings. The contrast with what ever you have as a warm base and the cool toppings is part of what makes it delicious. There are two mush have toppings for this dish.

First, crushed Nacho Cheese Doritos. This is a perfect way to use up those chip crumbs that you find at the bottom of the bag. No one ever wants to eat those, that is unless those crumbs are on top of this dish.

Second, you’ve gotta have sour cream. The cool creaminess is a nice complimaent to the crunchy chips and flavorful beefy rice casserole. Chopped cilantro or diced green onion are good to include on top of this Instant Pot Beef Nacho Casserole, but not necessary.
