What are tater tots?
If you are in the United States you are probably familiar with what tater tots are, but other regions have asked me many questions about tater tots.
- Tater tots are a potato product that is crunchy on the outside and tender on the inside. They are made from grated potato that is shredded and formed into a cylinder shape and deep fried.
- In the UK, tater tots may be called Potato Crunchies or Mini Hashbrowns.
- In Canada, you may find them labeled as Spud puppies or Tasti Taters.
- In Australia or New Zealand, they may be called Potato Gems or Potato Royals.
Regardless of where you’re from or what you call them, they are absolutely delicious and the highlight of any tater tot casserole recipe.
What you need:

- Ground Beef: Go for a leaner beef if you want less fat content.
- Tater Tots: All you need is a bag of frozen tater tots. We use this same bag in our slow cooker breakfast tater tot casserole.
- Green Beans: Adds a hearty touch to the casserole.
- Cheddar Cheese: Shredded and sprinkled on top for a cheesy finish.
- Condensed Cream of Mushroom Soup: Provides a creamy and tasty texture to the dish.
- Milk: Added with the mushroom soup to thin out the sauce.
- Onion: A small diced onion is added for enhanced flavor and heartiness.

How to make slow cooker tater tot casserole:






Step One – Brown ground beef and onion in a skillet and drain the fat.
Step Two – Add cream of mushroom soup, milk, salt and pepper to the beef. Stir. Set aside.
Step Three – Add half a bag of frozen tater tots to the bottom of the slow cooker.
Step Four – Then add green beans.
Step Five – Now add the remaining tater tots.
Step Six – Pour the ground beef mixture over the tots and spread out to an even layer. Sprinkle over the cheese. Cover and cook on low for 5 hours without opening the lid during the cooking time.

Variations
This recipe is great as-is, but here are some great ideas for making it your own.
- Although this recipe calls for cream of mushroom soup, you can also use cream of chicken soup or cream of cheddar soup.
- Ground chicken and ground turkey are great substitutions and taste just as delicious.
- Canned green beans or frozen can be used instead of fresh. You can add other vegetables instead of green beans such as corn, frozen peas, carrots or mushrooms.
- Other cheese options are mozzarella or pepperjack cheese.

My Serving Suggestions
Here are my favorite ways to serve this wonderful casserole.
- This easy tater tot casserole is served perfectly as is. Simply scoop a nice helping into bowl and enjoy.
- This can be topped with extra cheese, hot sauce, chives, and/or sour cream. We are guilty of topping ours with ketchup! It’s so good.
- If you want to add more to the meal consider adding a green salad and dinner rolls.

Recipe FAQs
Yes, though you will find the texture is great. The potatoes break down into little bits, creating a wonderful texture to the casserole. If you are on the fence about trying this, just try it once; it’s one of the best meals you will make in the slow cooker.
Any remaining casserole can be stored in an airtight container and kept in the fridge for up to 4 days.
On my blog, I have a version of this made with hash browns (not fried) and that really lightens up the recipe. You can find that recipe here: Slow Cooker Lightened Up Tater Tot Casserole.

The flavors all come together after slow cooking. Try this recipe out this week and leave a comment on what you thought. Enjoy!

I mix rotel tomatoes & green chili and Cambell’s Fiesta Nacho Cheese Soup with the meat and pour it over cooked tator tots in a cake pan and put it in the oven with shredded cheese on top. My family LOVES it. You can fry the tator tots or cook them in the oven. The crock pot idea would work too.
Do you drain your beef after browning? Or is the extra grease needed for the recipe, I would drain normally.
I would drain James! Great question!
I grew up on this stuff and cook it regularly. I do it all different though. I use cream of mushroom soup and cream of celery mixed with the browned hamburger. Put all that in a casserole dish and top with a solid layer of tater tots. place in oven on 350 degrees for about 30mins or until the tater tots are golden brown then take out of oven, spread out a layer of shredded cheddar cheese and place back in oven. Let it cook until the cheese is melted then it’s ready to eat!!
I just put all of the mixture in the Crock Pot. It only took me 30 minutes! Awesome! And it looks amazing! Thanks for a great recipe!
Danielle do you cook the hamburger before putting everything in the crock pot or mix it raw with everything
My husband was just asking me to make this the other day! Now I have a great recipe to make – thank you, looks and sounds delish!
I’ve heard of tater tot casserole, but in the slow cooker I will have to try!
This sounds so good!I never thought to make it in the slow cooker!
I love tater tots! This is a rocking recipe! I think it’d be great at a potluck or even for a brunch. Thanks!
I cannot stomach tater tots so cut up potatoes into cubes and used Vegan Meat Crumbles for the ground beef and it turned out amazing too.
No…
My family is picky and doesn’t like mushrooms or green beans. I fried 1 lb hamburger, mixed with 2 cans creamed corn, then poured over 4 cups tater tots. 4 hours later (on low) it was amazing. Serves 3-4 people. I didn’t add any cheeses or milk.
Kim- That is such a great idea, dairy and gluten free!
Did you not add any soups either?
Easy to make and it tasted great loved it will make it again
