This past weekend we (finally) had some cooler weather. I’m taking it as a sign that it’s nearly my favorite time of year. The Fall weather also brings a back-to-school season which, itself, brings more hussle and bussle. Despite our new school year being remote, I still expect our weeknights to be very chaotic. So in an effort to streamline dinnertime and make something that everyone will love, I made this super easy Instant Pot Mexican Casserole recipe.

Why the Instant Pot
My husband has been using a pressure cooker for years. I’ve always hated the traditional pressure cookers because I think they are scary (and, quite honestly, I just don’t trust that I can use one properly). But if you’re holding out because you think the Instant Pot isn’t worth it — you’re oh so wrong!
I use my Instant Pot for literally everything: eggs, rice, spaghetti and meat sauce, and even yogurt! You can grab one here for a great price. Honestly, it’s an amazing investment. It saves me so much time when preparing meals for my family.
What you’ll need for Instant Pot Mexican Casserole
Besides an Instant Pot, you’ll need the following:

- 1 pound of ground beef
- 2 cups red enchilada sauce
- 3 cups cheddar cheese grated (divided)
- 10 corn tortillas cut into strips
- Sour cream (optional garnish)
- Cilantro (optional garnish)
- Black olives (optional garnish)
I know that many people feel differently, but we are Team Cilantro and Team Black Olives over here! So we definitely use them as a delicious garnish.

The recipe itself takes only a few minutes of prep. This is a one-pot meal, so you brown the ground beef right in the Instant Pot itself! Just use saute mode to brown the beef, then add all of your ingredients to the pot! Super easy!

Any tips for when it says food burn when cooking on high to melt the cheese? Thanks
When is the food burning? It shouldn’t burn at all. If you want to add the cheese at the end, cook without the cheese. Then release the pressure, remove the lid, add the cheese, and place the lid back for three minutes (it will melt without being turned on).
