Easy Cheesy Tater Tot Casserole with Sour Cream

A super easy tater tot casserole that’s extra cheesy with seasoned ground beef, onions, garlic, sour cream, mushroom soup and frozen tater tots. It’s the perfect easy family dinner.

This casserole is just one of those bakes that you can just easily whip together in a short amount of time, but it still tastes amazing and everyone always wants seconds.

It’s basically a different take on the classic tater tot casserole because you’ll add a bit more cheese (who doesn’t love that?) and a bit of sour cream to make it rich and creamy. It’s definitely pure comfort food.

This recipe will make a full 13×9 inch pan full of tater tot casserole goodness. If you need to feed even more people, you could always double it and bake in two 13×9 inch pans.

Kids sometimes like to eat this with ketchup, but you could always pile on some extra sour cream or even add a little drizzle of ranch dressing to make it the best ever.

The good part is that this recipe doesn’t call for green beans like other tater tot casseroles do. Nope, we’ve got none of that happening here.

Don’t get me wrong, you could always add green beans as a side, but I’ve never understood why anyone would want them added and mixed into the casserole though but to each their own.

Ingredient Notes:

Let’s talk a little bit about just some of the ingredients in this casserole. The full list of ingredients will be in the recipe card below.

Ground beef – You can use whatever ground beef you prefer for this, but make sure to drain off the grease once it’s fully cooked.

Chopped onion – I used yellow onion, but you could also use white onion.

Worcestershire sauce – This just gives it a little extra zing. It’s optional, but it really adds a lot of flavor to it.

Cream of mushroom soup – This is a good part of what makes this casserole creamy. In my opinion, it’s best to use the name brand.

Sour cream – This also helps with the creaminess and adds a little flavor and tang. This isn’t in your average tater tot casserole and I really think it makes a big difference.

Shredded cheese – You definitely want cheese in your casserole and you can use really any you prefer, but I’ve found that cheddar or colby-jack cheese works the best.

Frozen tater tots – This is the star of tater tot casserole. Use frozen and in any brand you like. Adding them in a single row on top works best.
