This tater tot casserole recipe draws on one of the American Midwest’s most enduring comfort-food traditions, and at its core the formula is straightforward: lean ground beef, a cream of mushroom soup base, frozen vegetables, cheese, and a crown of crispy tots baked until the edges bubble. The whole thing is on the table in just over an hour, with only ten minutes of prep.
A Dish With Deeper Roots Than You Might Expect
The hotdish has a longer documented history than its humble ingredients suggest. According to America’s Test Kitchen, the first published recipe for hotdish appeared in a 1930s community cookbook produced by the Grace Lutheran Ladies Aid from Mankato, Minnesota. It was submitted by a Mrs. C.W. Anderson and called for hamburger meat, canned tomato soup, peas, Creamette brand elbow macaroni, and celery. The bones of the modern version (tinned soup, ground meat, vegetables stretched to feed a crowd) are all there.
The dish has since embedded itself so thoroughly in Minnesota culture that, according to America’s Test Kitchen, making hotdish has become a rite of passage for joining Minnesota congress. It is, in other words, more than dinner.
What Goes Into a Tater Tot Casserole Recipe
The recipe below serves eight and starts with a base built for depth. Yellow onion and garlic are cooked down in olive oil over medium-high heat for seven to eight minutes until lightly browned, forming a buttery backbone before the beef goes in.
For the meat, stick with lean ground beef of at least 85%. The casserole carries plenty of richness from the cream of mushroom soup, butter, and cheese, so there is no need for extra fat, and because the beef is not drained after cooking, a leaner cut keeps things balanced.
Once the beef is browned and seasoned, it is set aside while a roux is built in the same pan. Butter is melted, flour is whisked in until the mixture turns bubbly and fragrant, and then three-quarters of a cup of low-sodium chicken broth is added gradually until the sauce thickens and smooths out. A tin of cream of mushroom soup goes in next. Using low-sodium broth matters here: the canned soup carries salt of its own, and seasoning in stages is the safest route.
The assembly layers in Worcestershire sauce, yellow mustard, frozen corn and frozen green beans alongside the meat, then half the grated extra-sharp cheddar. Those two vegetables echo the original Midwestern logic of stretching a pound of beef further. The mixture is poured into a 13-inch by 9-inch baking dish, the remaining cheese goes on top, and then come the tots, arranged in horizontal rows with a small gap between each. The recipe calls for Ore-Ida or any comparable brand, roughly 72 tots for the full dish.
The casserole bakes at 375° for 35 to 40 minutes, until the centre and edges are bubbling and the top is crispy. A scattering of thinly sliced scallions finishes it off, though sour cream and hot sauce are both welcome additions.
Getting Ahead and Storing Leftovers
The base (everything below the tots) can be made up to two days in advance and kept in an airtight container in the refrigerator. When you are ready to bake, transfer it to the dish, add the cheese and tots, and proceed as normal.
Leftovers keep for up to two days in airtight containers once fully cooled. For longer storage, the casserole can be portioned into individual foil packets and frozen for up to a few weeks, making it a practical option for reheating at short notice.
