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.

How to Make the Best Tater Tot Casserole with Green Beans
Like nearly every great comfort casseroles, this hotdish is prepped in only a matter of minutes, and is on the table in under an hour.
Follow these easy 5 steps to prepare a satisfyingly cheesy cowboy casserole with tater tots:
- Preheat the oven to 375 degrees Fahrenheit.
- Cook the ground beef in a large skillet, stirring frequently until browned throughout. Add the green beans, onion, and garlic. Continue to saute and stir until the onion becomes translucent.
- Next, stir the canned soup into the beef and veggie mixture. Transfer to a large casserole dish. Or, if you are making as a complete one skillet meal, simply keep everything in the pan and move on to step #4.
- Sprinkle the shredded cheese evenly over the mixture. Then add a single layer of frozen tater tots to the top.
- Bake the casserole uncovered for 30 minutes. The tots should be golden brown and the cheese bubbly. Let the cowboy tater tot casserole rest for 5 minutes before serving hot.
How to Make Ahead and Freeze
This casserole recipe is perfect to prepare either as a full make ahead meal, or you can even prep two pans at the same time. That way you can enjoy one casserole hot for dinner that night, and freeze the second to have ready for meal trains, holidays, family gatherings, potlucks, or anytime you need a dish to share.
Tip: If you are making ahead to freeze, I recommend that you prepare in a foil pan. That way the casserole can go straight from the freezer to the oven!
Simply put together the tater tot hotdish per the recipe but do not bake. Cover with a layer of aluminum foil (double wrap with foil if freezing). Then either keep in the refrigerator for up to 3 days before baking and serving, or freeze for up to 3 months.
Tips for Reheating Frozen Tater Tot Casserole
There’s no need to defrost the dish before baking! Preheat the oven to 375 degrees, and place the uncovered foil pan in the oven.
You want to add 15 minutes to the regular cook time, so the casserole will need to bake for about 45 minutes. But keep an eye on it after 30 minutes to make sure it doesn’t get too browned.
What to Serve with Cheesy Cowboy Casserole
Garnish this hot dish casserole with sour cream, sliced green onions or parsley. And cooked chopped bacon for an even heartier and more savory dish.
