It began on a Tuesday. A night I’d promised tacos. Taco Tuesday. A dish we love, but rarely have on Tuesdays. But it had been a busy week, and I was up for something… different.

And for some strange reason, I’d been thinking about Tater Tots.

We rarely ever have Tater Tots. At least a year, perhaps even more. Which is strange in a house with teens and their friends.

You know how minds can ramble when considering, “What to serve for dinner.” I wondered if anyone would be terribly disappointed if Tuesday’s tacos became taco tater tot casserole?

If I served them with corn tortillas, they could stuff the casserole into the tortillas… and it would be like a taco, right?

So that Tuesday became Mexican Taco Tater Tot Casserole Tuesday. The result? No disappointments that night! And sadly, no leftovers either.

Frequently Asked Questions

Can I make this Tater Tot casserole ahead?

Yes! Just assemble it ready to bake and stash it in the fridge up to a day ahead. It won’t matter that the Tater Tots thaw in this time. The leftovers – without the fresh toppings – will reheat well too, if there even are any!

Can I switch out the ground beef?

Sure! Turkey and pork would also work well, and while I’ve not tried it I think quoin mince would also make a pretty good vegetarian version. Do let me know if you give it a go!

  • 1 pound lean ground beef I use 7%
  • 1/2 medium onion chopped
  • 2 cloves garlic minced
  • 2 tablespoons taco seasoning or 1 packet
  • 1 teaspoon chili powder
  • 1/2 teaspoon cumin
  • 4- oz can of diced green chiles
  • 1 cup frozen corn
  • 15- oz can black beans
  • 2 tomatoes diced and divided
  • 8- ounce can tomato sauce
  • 1/3 cup salsa
  • 1 2.5 oz can sliced olives
  • 2 cups Mexican shredded cheese divided
  • 1 16 oz bag frozen tater tots

Topping Ideas:

  • Diced Tomatoes
  • Sliced Scallions
  • Sliced Olives
  • Sour Cream
  • Sliced Avocado


  • Preheat the oven to 400°.
  • Brown the ground beef, onion, and garlic in a large skillet. Drain the fat.
  • Stir in the taco seasoning, chili powder, and cumin. Add the chiles, corn, black beans, 1 chopped tomato, tomato sauce, salsa, and 1/2 of the canned olives. Cook until thickened, about 2 minutes or so.
  • Transfer meat mixture to a 9×13 inch baking pan and smooth evenly. Spread 1 cup Mexican shredded cheese over the meat mixture and place tater tots in a single layer on top.
  • Bake in a 400° oven for 30 minutes. Remove from oven and top casserole with remaining chopped tomato, remaining 1 cup shredded cheese, remaining sliced olives, and sliced scallions. Bake for an additional 10 minutes until the cheese is melted and casserole is bubbling.
  • Serve with additional topping ideas suggested above.


If you like your tacos with a bit of heat, choose “medium” or “hot” spiced salsa and green chiles instead of “mild.”
