What is Tater Tot casserole?

Growing up most of our meals were made in the slow cooker or quick skillet meals mostly from scratch. I recall filling meals like pan-seared chicken with boiled potatoes and a green salad. Or, a crock pot pot roast or beef stew.

My husband, however, grew up loving delicious comfort meals with mashed potatoes and gravy and smothered chicken or pork chops.

So, when I saw first saw tater tot casseroles or hotdish recipes as they’re called in the upper Midwest, I knew it was something my husband would love. Not only is he from Michigan, but he loves a good cheesy potato dish!

This deliciously easy casserole recipe, also known as cowboy tater tot casserole, is made with simple ingredients that many families consider staples. It includes ground beef, milk, cheddar cheese, green beans, onion, cream of mushroom soup, and tater tots. So it’s truly a complete dinner baked in just one pan!

Tip: Turn this tater tot casserole into a one skillet meal using an oven-safe skillet, like a cast iron skillet.

Ingredient Notes and Substitutions

  • Ground beef – Lean is best, I recommend 85% lean ground beef. Make a leaner hot dish by using ground turkey or ground chicken in place of ground beef.
  • Green beans – frozen, fresh, or canned
  • Aromatics – We used onion and garlic for this recipe.
  • Cream of mushroom soup – You can also use cream condensed soup. If you want an even cheesier cheesy tater tot casserole, use condensed cheddar cheese soup instead of cream of mushroom.

    If you’re not a mushroom fan, you can also try cream of celery soup or cream of asparagus soup.
  • Cheddar cheese – freshly shredded or grated is ideal for this recipe. For a spicy recipe to really put a kick in your spurs, use shredded pepper jack in place of cheddar cheese.

    Or do a half and half blend. You can even add a dash of Frank’s Red Hot to your plate if you are a spicy lover.
  • Tater tots – Frozen tater tots are the perfect topping for this dish.
