Vegetarian Tater Tot Casserole Hotdish
What’s this casserole called a hotdish? Have you heard of them?
I didn’t even know it existed until I’d been blogging for a while. Seeing variations of this Midwestern casserole on Pinterest and Instagram had me exploring ways to create my own sort with a bit of my Texas roots spin
A hotdish is a casserole baked in one dish, served hot and generally consists of a starch, meat, vegetables and canned soup. While this vegetarian tater tot casserole doesn’t fully fit the traditional definition of a hotdish, there are so many ways and variations, I figured I could get by squeezing one more in.
Where I grew up in Texas, we always called these types of recipes casseroles, but still, I’d yet to see any tater tot casserole, without meat, of my childhood covered in tater tots. This is something I’d never forget.
If you enjoy homemade chili, soups and stew recipes, you’ll enjoy this cozy chili recipe.

The Best Ingredients
This easy gluten free vegan or vegetarian chili tater tot hotdish relies heavily on spices to create its hearty and mouthwatering flavors. A must in any chili recipe is high-quality chili powder. Frontier Co-op’s Organic, Non-GMO Chili Powder is a blend of spices including chili pepper, cumin, oregano, coriander, and garlic, to create a robust yet balanced flavor that’s not too spicy. I use it in all my chili recipes, and then some.
To take the spicy up in this vegetarian tater tot casserole, I’ve saved that job for jalapeños – as always, add more to taste or pile fresh or pickled on top!

Quick Guide: How To Make Chili Tater Tot Casserole Hotdish
This recipe comes together in one pan! Could it get any easier? In summary, here’s how to make it (see recipe card below for details):
- First, start by making the quick and easy vegetarian chili base in a cast iron skillet, sautéing flavor builders like onions, garlic, jalapeños and spices.
- Next, add the beans and broth then top with cheese and tater tots. For an easy vegan chili casserole, simply leave the cheese off.
- Last, pop it in the oven for about 30 minutes and what emerges is a completely mouthwatering vegetarian casserole (just bury me in tater tots… mmmK?).
A hearty gluten free chili underneath melty cheddar and crispy tater tots. Omit the cheese and this recipe easily becomes a fabulous vegan chili tater tot casserole. Serve with a variety of toppings to make it your own, like green onions, cilantro, avocado, jalapeños, pepita crema and/or sour cream.
I know what you may be thinking…. more cheese on top?Â


Pro Tips
- The Beans: Black beans are also lovely in this dish. Sub black beans for kidney or pinto for a delicious variation. While canned beans are so convenient, you can use Home Cooked Black Beans and/or Pinto Beans in this recipe.Â
- Freezer Friendly? Yes Please! This vegetarian tater tot casserole makes excellent leftovers and is freezer friendly.
- Vegan Friendly? You got it! Omit the cheese or use your favorite plant based cheese to make this a vegan chili tater tot casserole. You can make it 1/2 n 1/2 for cheese lovers and cheese avoiders!
- While the ingredient list looks long, it’s mostly pantry staples. Do not let it deter you!Â

Vegetarian Chili Tater Tot Hotdish
Ingredients
- 1 1/2 tsp Vegetable Oil, I like coconut or olive oil
- 1 1/2 C (190g) Purple Onion, chopped, about one medium
- 1 C (125g) Green Bell Pepper, chopped, about one medium
- 1 Tbs Pickled Jalapenos, diced small
- 1 Tbs Garlic, minced
- 1 1/2 Tbs Chili Powder, I use Frontier Co-op, organic
- 2 tsp Black Pepper, ground
- 1/2 tsp Fine Sea Salt
- 1 1/2 Tbs Masa Harina, *see note for sub and more info
- 2 Tbs Tomato Paste
- 1 C (245g) Fire Roasted Tomatoes + juice, diced, freeze the leftovers
- 1 1/4 C (280g) Vegetable Broth
- 1 Tbs Dried Oregano
- 2 C (425g) Pinto Beans** (see note), cooked, drained (one can)
- 2 C (425g) Kidney Beans, cooked, drained (one can)
- 20 oz (567g) Prepared Tater Tots
- 1 1/2 C (115g) Cheddar Cheese, shredded, optional
Instructions
- Preheat oven to 400F (205c). Set oven rack in center of oven.
- Into an oven safe 10" (25cm) skillet (I use cast iron), add the oil and heat until shimmering. Add the onions and bell peppers. Cook on medium-low for about 9-10 minutes, or until softened, stirring occasionally. Charring is good.Â
- To the skillet, stir in the jalapeños and garlic. Sprinkle in the chili powder, ground black pepper, salt and masa harina. Stir to coat vegetables, about one minute. Stir in the tomato paste, tomatoes, broth, oregano, and beans. Warm to a simmer, then remove from heat. Taste for salt adjustment, reseason if needed.
- Sprinkle the cheese over the top if using (or 1/2 the amount for those who may not want cheese), then arrange the tater tots on top of the cheese (or over the chili) in a circular pattern. Bake in a 400F preheated oven for 30 minutes, until tater tots are golden and crisp and the chilly is bubbling underneath.
- Serve with avocado, jalapeños, cilantro, green onions, and/or sour cream. Store in a lidded container in the refrigerator for up to three days. Freeze for up to two weeks.

I loved this recipe! It was easy to make and of course, had left overs. That’s always a win! I had to make a couple of changes because of ingredients I did and did not have. I had red pepper not green. No jalapeños so I used another pepper I had. Great weeknight meal!
Hi Joy! Thank you for your note and sharing your tips about using what you had on hand. Leftovers FTW! So happy to hear you enjoyed the hotdish!
LOVE THIS! Have made 2 weeks in a row, and I claim all of the leftovers for my lunch the next day 😂
I never found the masa harina, but I only add a T or 2 of broth and it’s perfect.
Hii Autumn! Thank you so much for your note and rating! So happy to hear you’re enjoying the recipe, even without the masa! Hooray!
Made this tonight and it was great. I used sweet potato tater tots which were delicious.
SO happy to hear Cathy! Thank you for your note, rating and giving the recipe a go! Hooray for sweet potato tater tots!
Hi. What can you sub for the masa harina? I don’t want to buy a whole bag just to use a little bit here. Any suggestions?
Hello M! Unfortunately there’s really no sub as it has a very unique flavor. If you like, you can try grinding down corn chips in a food processor or blender (although I’ve not tried it), it’ll offer some of the flavor and thickening power missing from Masa Harina. If you’re not sure how you would use the masa harina in other recipes, you can try my Corn and Zucchini Fritters, and my Tofu Tacos. It lasts for a long time, and because it adds so much flavor and thickening, I keep it as a pantry staple. I hope this helps!
Hello, I frequently take a white or yellow corn tortilla and pulverize it in a food processor or mini prep processor. Then follow the recipe measure.
Hi Joanna! That’s a great tip! Thank you for sharing.
Loved it! So good. Thank you for such a great recipe. It will definitely go into the rotation.

Family loved it tonight and our skillet was empty! Easy and so tasty. Thanks for another great recipe.
Hooray! Thank you so much for your note Karen! So happy to read this!
This was excellent! Received rave reviews from my roommates. Loved the quick chili and how you can easily adapt spices, veggies, beans, etc for your own tastes and what you have in the pantry. Served with avocado, greek yogurt (in place of sour cream), cilantro, and lime wedges. The crispy & cheesy tots on top were delicious with the chili. Thanks for the recipe; this one’s getting saved in my recipe box.
Hooray! Thank you so much for your note Becky! Lucky roommates! The avo and greek yogurt sounds fabulous… and I’m SO with you on the crispy & cheesy tots on top (OMGeeee). So happy y’all enjoyed it!
