This Mexican Tater Tot Casserole is made for busy nights when you want all the comfort of a classic casserole with the punchy flavors of taco night. The crispy tater tot layer, savory beef and veggie filling, and plenty of melty cheese mean there will never be leftovers for long. My family started requesting this one regularly after I threw it together for a potluck and it came home wiped clean.
I first made this for a casual game night and every single person begged for seconds before the final whistle. Now it is my go-to for chilly nights when we want a fun twist on the usual taco casserole.
Ingredients
- Ground beef: brings hearty and rich flavor, look for good marbling and freshness
- Onion: for sweetness and aromatic depth choose yellow onions for balance
- Taco seasoning mix: delivers classic Mexican spice, homemade or store bought both work well
- Green chili: adds mild spice and brightness canned diced green chilies are easy to use
- Black beans: pack fiber and softness rinse well and pick no-salt-added if possible
- Frozen corn: brings bursts of sweetness and color use supersweet or fire roasted for variety
- Red enchilada sauce: creates warmth and moisture pick a flavorful brand you love
- Shredded cheddar cheese: for classic melt and tang use sharp cheddar for best taste
- Tater tots: get golden and crispy on top choose a brand that browns well
- Cilantro: for a pop of freshness always chop right before serving
- Sour cream: to cool and finish the casserole aim for thick and creamy varieties
Instructions
- Preheat and Prep:
- Preheat your oven to 375 degrees Fahrenheit and grease a nine by thirteen inch baking dish thoroughly to prevent sticking later
- Brown the Beef and Onion:
- In a large skillet set over medium heat, add the ground beef and diced onion. Break the beef apart as it cooks. Continue stirring and browning until the onion is translucent and the beef is completely cooked through. Drain off any excess fat and return the meat mixture to the pan.
- Build the Filling:
- Stir in taco seasoning, green chili, black beans, frozen corn, and enchilada sauce into the skillet with your cooked beef and onion. Mix until everything is evenly coated. Let this mixture cook for about eight to ten minutes so the flavors can meld and the ingredients are heated through.
- Add Cheese:
- Fold in two cups of shredded cheddar cheese now, mixing gently so the cheese melts slightly and the filling turns creamy and cohesive.
- Fill the Baking Dish:
- Pour your cheesy beef and bean mixture from the skillet into your prepared baking dish. Use a spatula to spread it out in an even layer so the topping cooks uniformly.
- Arrange the Tater Tots:
- Carefully place tater tots in rows across the top of the filling, making sure they cover the entire surface. This helps them bake evenly and get extra crisp.
- Bake:
- Slide the casserole into the oven and bake uncovered for thirty five to forty minutes, until the tater tots are deeply golden and crispy all over. The filling will be bubbling underneath.
- Add Final Cheese Layer:
- Sprinkle the remaining cup of shredded cheddar over the hot tater tots as soon as the casserole comes out of the oven. Return it to the oven for another five minutes, just until the cheese is melted and starting to brown.
- Garnish and Serve:
- Remove the casserole from the oven. Sprinkle freshly chopped cilantro across the top and add dollops of sour cream right before serving for a creamy finishing touch.

My favorite ingredient here has to be the tater tots. My dad used to jokingly call this recipe breakfast for dinner because of those crisp potato bites on top. The best memory I have is the kids building their own mini piles of tots before sharing the casserole around the table.
Storage Tips
Let the casserole cool completely before covering tightly with foil or transferring to airtight containers. It keeps well in the fridge for up to four days. For best results when reheating, use the oven or toaster oven to re-crisp the tater tots. You can also freeze baked or unbaked casserole for up to three months. Thaw overnight and bake until hot and bubbly.
Ingredient Substitutions
Try ground turkey or chicken for a lighter option. Vegetarian protein crumbles or cooked lentils make this dish meatless. Pepper Jack or a Mexican cheese blend adds even more zing. No enchilada sauce available Mix a bit of salsa with tomato sauce for a similar effect.
Serving Suggestions
Serve with a side of crisp lettuce, sliced radishes, or a crunchy cabbage slaw to balance the hearty casserole. A squeeze of lime over the top brightens everything right before serving.
Cultural Context
While tater tot casserole is classic Midwest American fare, this version borrows flavors from Mexican dinners. It is a fusion dish that fits right in on Taco Tuesday as easily as on a cozy Sunday evening.
Seasonal Adaptations
Add diced fresh bell peppers or zucchini in the summer for extra color In fall, stir in a cup of roasted sweet potato for warmth Try fire roasted corn or fresh tomatoes when in season
Three Helpful Notes
Let the casserole rest for five minutes before serving so the filling can set You can use pickled jalapeños for added heat on top before baking Leftovers make a great wrap filling or breakfast hash the next day
Success Stories
I sent this casserole to my neighbor when she had a new baby and she still tells me it is her most requested comfort food. It is my reliable pick when someone needs a meal that is both fun and familiar.
Freezer Meal Conversion
Prepare as directed but stop before baking. Cover the assembled but unbaked casserole in a couple layers of foil and freeze. Bake from frozen at 350 degrees Fahrenheit for about an hour or until bubbling and golden.

This is my family’s most-requested comfort food and always gets devoured. Give it a try for your next potluck or weeknight dinner!
