Simple Freezer Mexican Casserole

This Mexican Casserole is perfect for Taco Tuesday! Simple ingredients, easy to put together, and freezer friendly!

It doesn’t have to be Taco Tuesday to enjoy this Mexican Casserole!

Mexican food is probably my favorite style of food. I think it’s because I can take pretty much any form of a Mexican dish and turn it into a salad, which means more vegetables!

I mean if you think about it… ground meat, rice, beans, and corn can totally go in a salad.

What I love about this recipe is how easily it comes together. Once the rice and meat is cooked, you literally just mix everything together and either bake it right away or freeze it. And the serving sizes are huge!

What can you serve with this casserole?

I roasted some zucchini on the side for this. But I also threw all of this on top of lettuce for a huge salad! Top it with some sour cream and hot sauce, and you’ve got perfection.

Can you make this ahead of time?

You can assemble the casserole ahead of time and either put it in the fridge, or in the freezer if you plan to eat it way later. And since this doesn’t use a lot of ingredients, you could easily double the recipe- eat one now, and one later!

Can I make this vegetarian?

Sure! Instead of the ground meat, I’d add an extra can of beans for protein.
