Mexican Ground Beef Casserole Recipe

Warm ground beef, hearty potatoes and of course melty cheese make this the ultimate Mexican casserole!

Mexican food is my love language. I’m pretty sure in a previous life I was talking Spanish and whipping up homemade corn tortillas every night of the week ending with “y”.

In reality, I took four years of Spanish and remember some random verb conjunctions and lots of vocab. Hey, it’s something, right??

Anyway, this easy peasy recipe is a cross between a tater tot casserole and a taco casserole.

Translation: It’s an easy weeknight meal your family will love!

Ingredients in Easy Mexican Ground Beef Casserole

ingredients in mexican beef casserole
  • breakfast potatoes – I used cubed breakfast potatoes but you could also use hash browns
  • ground beef 
  • Salsa – pick your favorite jarred salsa or make some of my restaurant style salsa. I usually go with a medium salsa on the spice-o-meter.
  • sweet corn kernels – you can use fresh, frozen or canned corn
  • shredded cheese – is there really such a thing as a wrong cheese? (short pause). I didn’t think so. I used shredded cheddar cheese but a Mexican cheese blend would be downright delicious!
  • green onions – these add a nice bit of color and some fresh flavor on top of the casserole

What to serve with this Mexican Ground Beef Casserole Recipe

Of course, I am here cheering you on as you add your favorite taco toppings. I’m thinking a dollop of sour cream or Greek yogurt for some creamy tang, maybe some sliced black olives over the top.

Ooooh, and if you’ve got an avocado or two, you should totally add some homemade guacamole!

I get excited, what can I say?!? Whatever you’d add to a taco, you can add to the top of this Mexican casserole.

On the sides, let’s take the vegetarian refried beans route. My recipe uses a can of refried beans and is seriously easy so no worries there.

Or, add some canned, drained and rinsed beans like black beans or pinto beans. And of course a side of tortilla chips with salsa or homemade pico de gallo.

Basically, they’re always included because my family would be lost on taco night without them.

Variations and Tips

If you’re out of salsa? No worries, you could substitute a can of rotel tomatoes with green chiles.

If you forgot to thaw your ground beef, no worries! You can easily thaw and cook ground beef in your Instant Pot.

How to store leftovers

Leftovers can be stored in an airtight container in the refrigerator.

To make this as a freezer meal, you can assemble the casserole and freeze, unbaked, in the freezer for 3-4 mounts.

    I have a bunch of regular fresh potatoes to use up. Could I use them in this recipe? Would I need to precook them?

    Hi Rachel, I haven't tried it, but if it were me, I'd add the potatoes to the casserole dish and cook them for 20 minutes, then add the rest of the ingredients as outlined and follow the recipe. Let me know!!
