This one is for you, TNNers.

As a born and bred Maine girl, I honestly had never heard about a tater tot casserole until a few years ago. But after I shared with you all on Instagram stories that I bought some frozen tater tots for my daughter to try, the requests for a veggie-loaded healthier tater tot casserole (often called a hot dish…I learned that) recipe came FLOODING in. So many of you asked for it, so I set to work learning about the midwest classic comfort food and figuring out how to put a veggie-loaded twist on it.

This recipe was a team effort with my pal Heather Staller, who helped test and perfect this seriously delicious casserole recipe. What we created together is a healthier version of the classic tater tot casserole. Loaded with frozen mixed veggies and frozen cauliflower rice to make veggie-loading easy breezy for you all, this tot casserole tastes somewhere between a Shepherd’s pie and a potpie and is allllllll the delicious comfort food you TNNers made it out to be. It is easy to make dairy-free and gluten free and works great as leftovers or to feed a crowd.

Why this Healthier Tator Tot Casserole is amazing….

  • Made with ground turkey. I lightened up the classic tater tot casserole recipe by making this version with ground turkey. If you find ground turkey recipes kinda blah, don’t worry! The seasoning worked into the casserole ensures it is flavorful as well as healthy.
  • Packed with frozen veggies. I love fresh veggies, but sometimes I love to lean on the ease of frozen vegetables when making a meal. This healthier tater tot casserole comes together extra fast since it uses mixed frozen veggies and frozen cauliflower rice….meaning there is next to no veggie prep!
  • Flavorful. A hearty flavor that just screams cozy and comforting.
  • Easy to make. This Healthier Tater Tot Casserole is made from lots of fridge and freezer staples. It is prepped and read to go into the oven with just 15 minutes of work and is done cooking in 20 minutes….making it the perfect veggie-loaded weeknight dinner.
  • Works great as leftovers. Cook once, eat twice. I love making a sizable casserole for dinner and then have the leftovers to enjoy for lunches or another night. This casserole keeps great, though the tater tots need a little crisping up in the oven when you reheat it!
  • It can easily be made gluten free or dairy-free. See the suggested adaptations section below.

Cheese on top? Or under the tots? Both? Maybe not at all?

Thanks to all of you, I learned that there are many, many ways to make a tater tot casserole and where the cheese goes (or if there is cheese at all) is a passionate subject.

And seems to be a personal choice!

Many recipes that I found while researching this recipe have the cheese on top of the tots. This is delicious and melty, but in the TNN version of Healthier Tater Tot Casserole, I opted to put the cheese under the tots so that the tots on top could get all crisp in the oven.

But you can totally place the cheese where YOU and your crew like it best. Put it on the top. Put it under the tots. Or do a little of both. Many of you messaged me that the versions you make don’t have cheese at all….so you can omit if that is what you love or works best for your dietary needs.

Suggested adaptations

Make this with ground beef. Not a fan of turkey? Use a pound of ground beef instead of the ground turkey in this Healthier Tater Tot Casserole. If there is a lot of fat in the pan after sautéing the beef, you can drain that before continuing with the rest of the recipe.

Make this tator tot casserole vegetarian. I have not tried any vegetarian subs for this recipe. However, I think cooked lentils, mushrooms, or a combination of both of those would be a great texture and flavor substitute for the ground meat.

Make it dairy-free. Use all broth instead of adding milk. For the cheese, you can use a dairy-free cheese or leave out the cheese. Many tater tot casseroles don’t use cheese at all!

Use fresh vegetables instead of frozen. Cook a finely diced large carrot with the onion in the beginning of the recipe, then you can add peas and corn if you wish. You can get creative and use whatever vegetables you have on hand: mushrooms, peppers, green beans, and cauliflower would all be great. Just make sure your vegetables are tender before you bake them with the tater tot topping.

Use sweet potato tater tots. Either store bought or homemade!

Make this gluten free by using gluten free tater tots. Tater tots are made from potatoes, but often contain wheat. If you need gluten free, be sure to read the ingredients on the bag and/or check to make sure they are certified gluten free.

Can I make this casserole ahead of time?

Absolutely! I love to make this Healthier Tater Tot Casserole ahead of time. You can prep it the night before and store it covered in your oven until you are ready to bake. Or, cook it ahead of time and enjoy it a little at a time for days to come.

To reheat, I liked to throw the casserole dish into a 325℉ oven covered in foil to warm up for about 15 minutes. Take the foil off, and place back into the oven for another 5 minutes to let the tots crisp a bit.

You can microwave the leftovers of this healthier tater tot casserole, but the tots won’t have a crispness to them like it does fresh from the oven.
