The Classic Tater Tot Casserole

Tater Tot Casserole is a classic dish for busy weeknights and potluck dinners, but this recipe takes it up a big, delicious notch by using a homemade sauce.

Many of us have fond childhood memories of tater tot casserole (or as we call it, “hot dish“). Whether it reminds you of the busy weeknights when your mom needed a quick and easy dish to throw together to get dinner on the table or church potlucks that were never complete without so-and-so’s “famous” hot dish, tater tot casserole is a comforting dish that takes many of us straight back to childhood.

Really, what’s not to love about tater tot casserole? We’re talking about creamy hamburger gravy topped with gooey, melted cheese and perfectly golden and crisp tater tots, after all.

Oh yeah. There’s the fact that the star ingredient of classic tater tot casseroles (aside from the tots, of course) is canned condensed soup. And while there’s nothing wrong with taking a shortcut in the kitchen to get dinner on the table quickly, making your own sauce is super easy. And if you’re making your own sauce instead of using condensed soup, you can also make Homemade Tater Tots with our tasty recipe before building your casserole.

We can totally do this, can’t we? Yes, we absolutely can. Your family is gonna love this Ultimate Tater Tot Casserole because it tastes even better than the casserole of your childhood memories.

We’re going to do this by scratch-making a quick creamy mushroom pan sauce, which is loaded with baby portabellas, fresh herbs and garlic. It’s a seriously easy step that takes no more than 10 minutes from start to finish, but the difference in flavor that it gives to the casserole is astounding.

The mushrooms taste so much fresher and juicier than canned cream soup counterparts, and the flavor is enhanced by the hearty flavor of fresh rosemary and thyme. It sure isn’t your grandma’s hot dish, but we guarantee she’ll be obsessed with it too.

Instructions

1. Preheat the oven to 425ºF. Heat a medium (10-inch), oven-safe skillet over medium-high heat. Line a plate with paper towel and set aside. Place the ground beef in the skillet and brown, breaking apart the beef into bite-sized pieces with a wooden spoon as it cooks. Cook for 5 to 7 minutes, until the beef is cooked through. Using a slotted spoon, transfer to the paper towel-lined plate to drain any excess grease off of the beef. Set aside.
2. Add the onion and mushrooms to the skillet and season with the salt and ground pepper. Stir to coat the onions and mushrooms in the residual grease in the skillet. Cook, stirring occasionally, for 5 to 7 minutes, until the onions are translucent and the mushrooms appear juicy. Add in the rosemary, thyme and garlic. Stir to combine. Cook for another 1 to 2 minutes, until the garlic is golden and the herbs are fragrant. Add the browned beef back into the skillet, stirring to combine.
3. Sprinkle the flour over the beef, onions and mushrooms, stirring to combine. Cook for 2 minutes, until the flour smells toasty and is no longer white. While stirring, slowly add in the milk. The milk will bubble violently at first, so take care to use your wooden spoon to scrape the brown bits up off of the bottom of the skillet as you add the milk – this is where the flavor is! Reduce the heat to low and cook, stirring occasionally, for 5 minutes, until the sauce is thickened and creamy. Add the corn and peas, stirring to combine. Taste and season with additional salt and pepper as desired.
4. Turn the heat under the skillet off and top the beef and mushroom sauce with the shredded cheddar. Add the tater tots, one at a time, arranging them in a single layer that covers the top of the casserole completely.
5. Bake the tater tot casserole for 30 minutes, until the tater tots are golden brown. Cool for a few minutes before serving.
