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.

    Very easy directions and OH SO YUMMY. I love this version however I did add a layer of tots to the bottom of the dish. I have a large family to feed. But I do love this version best of all.

    I’ve been making this version of Tater Tot Casserole for some years now. the only difference is I use canned cheddar cheese sauce ( Not cheddar cheese soup), the kind you can use for nachos. About a half of a can cheddar sauce, instead of the sprikle cheese in with the ground beef mixture. And about half a teaspoon of Montreal Steak seasoning. It’s the BEST TATER TOT CASSEROLE recipe ever. I usually make a double batch, hubby likes like to take for lunches and son likes it for snacks. Because it reheats soo well.

    • Hi Theo, thanks so much for your review and comment! I LOVE canned cheddar sauce and never really thought to add it to this. What a great idea! I’m definitely going to try it as well as the Montreal steak seasoning the next time I make this!
