Mexican vegetarian tater tot casserole is a delightful dish that the whole family will enjoy. Add some excitement to taco night by serving this flavorful, meatless twist on a classic favorite.

Vegetarian Mexican Tater Tot Casserole Recipe
Depending on where you live, you might want to call this Mexican tater tot casserole recipe a hot dish instead of a casserole. “Vegetarian Tater Tot Hotdish” has a certain ring to it that I like! The traditional tater tot hot dish comes from the Midwest, specifically Minnesota.
There, a hotdish would include tater tots, ground beef, and a vegetable. This hot dish is, of course, vegetarian, and gets its protein from black beans instead of meat.
Tater Tots never go out of style on the dinner table. Did you know that? It's true! You can dress up a tater tot in so many ways. For this vegetarian tater tot casserole recipe, we decided to put a Mexican spin on our tots, so we created a Mexican-Style Tater Tot Casserole.
What I love about this tater tot hotdish recipe is that it’s classic comfort food. It’s a simple vegetarian recipe without beef, and it has such a delicious flavor. (If you wanted to add in meat to brown the ground beef up, you could, we just don’t eat meat in our home)
This tater tot casserole with cheese is seriously going to be a favorite in your home.
For a fun Mexican meal, make these easy Mexican Sugar Cookies for dessert!

Our entire family loves the tots, from adults to kids. This recipe elevates the flavor with a Mexican-inspired flair.
What's In Vegetarian Mexican Tater Tot Casserole?
The base of this recipe is packed with tasty and filling vegetables. We mixed:
Tater Tots - shredded potatoes are a must for this casserole. Frozen tater tots do the job perfectly. Always check ingredients to ensure the bag does not contain allergens.
Sauteed Onions - These give a warm, home-cooked base flavor to the casserole. We love Vidalia onions for their sweetness. Yellow onion also works.
Black Beans - Black beans are our vegetarian protein for this dish. Use canned beans to save time.
Corn - Frozen corn is one of my favorite ingredients to have on hand. It's just as delicious as fresh corn, but much less expensive and easier to work with.
Traditional Mexican Taco Fillings - I'm using shredded Mexican cheese blend, black olives, and cilantro.
Gluten Free Enchilada Sauce - Adds tons of flavor as the top layer of the casserole.

HOW TO MAKE MEXICAN TATER TOT CASSEROLE

These numbered steps match the numbered photos above and are for illustration purposes. For the complete list of ingredients and instructions, please see the recipe below.

VEGAN MEXICAN TATER TOT CASSEROLE
Make this recipe vegan by swapping out the cheese for a non-dairy cheese. I like Daiya or Violife shredded cheese. You could also leave out the cheese entirely, and this meatless tater tot casserole would still be delicious.
What sides go with this meatless tater tot casserole?
This really can be a meal on its own. But if you want a side dish to go with this Mexican vegetarian tater tot casserole, a salad or other veggie-packed side dishes go great with it.
You could serve this Caesar salad or a Fruit Salad to lighten things up a bit.
Can I freeze this vegetarian tater tot casserole?
I haven't tried freezing this recipe, but I think it would work well. It would be a delicious make-ahead meal that you could pop in the oven. I would, however, package the cheese, olives, and cilantro in their own container, since you add those ingredients at the end.
Do I need to thaw the tater tots for this casserole?
Nope! And actually, I wouldn’t recommend it. The tots would get mushy and start to fall apart if you let them thaw too much. Just put them in the freezer. They will cook that way perfectly.

I've never heard of a recipe like this but it sounds tasty! Thank you for sharing!
I agree with some of the other comments about putting in fajitas veggies. I also thought you could change it up and use rotel tomatoes with green chili's instead of the enchilada sauce. Just a thought! Looks yummy as is too!
This looks great. I'll definitely add it to my to-try list!
