Tater Tot Casserole
Updated September 2026 with safe cooking times, a dairy-free guide, variations, and answers to common questions.
I have got to get a camera to post pictures until that day, you’ll just have to imagine.
Tater Tot Casserole
Borrowed from Ashley Shelton’s Dad
Ingredients:
- One can cream of mushroom (or use this great recipe from Must Follow Recipes if you’re dairy free like me!)
- Two cans of french cut green beans
- 1 lb of ground beef
- 1 bag of tater tots
- Salt and pepper, garlic powder, cajun powder
- Optional: Cheese (if you’re not lactose intolerant)
Instructions:
- Preheat oven to 400. Grab a 13x9 in glass pan.
- Take ground beef and smash it into the bottom. No need to cook. We’ll cook it long enough for it to get cooked. If you would like to cook it before hand, that would just make it faster. Add some cajun powder, garlic powder, and pepper.
- Then take your cream of mushroom and spread that across.
- Open the can of green beans and spread those across. Add pepper and salt.
- Open the bag of tater tots and lay those across. Add salt.
- Add cheese if you’re not lactose intolerant.
I cooked it for about 30 minutes or so. I would go by whatever that tater tot bag says and check the middle of the ground beef. If it’s brown, you’re good.
Enjoy! I love to add ketchup to mine.
Cooking time and food safety
Here’s the one thing I’d add today. If you put the ground beef in raw, it needs more time than the tater tot bag says. The beef is on the bottom under a layer of soup, green beans, and frozen tots, so it heats slowly. Plan on 45 minutes to an hour at 400º, and check the center.
The most reliable way to check is an instant-read thermometer. Ground beef is safe at 160º F. If you don’t have one, cut into the very center of the pan and make sure there’s no pink and the juices look clear. If the tots are browning before the beef is done, lay foil over the top and keep baking.
If you want dinner on the table faster, I recommend browning and draining the beef in a skillet first. Then the casserole only needs about 30 to 35 minutes, just long enough to heat through and crisp the tots.
Yield and pan size
A 13x9 pan with one pound of beef and a standard bag of tots serves about 6 people. Let it rest for 5 minutes before serving so the soup layer thickens up a bit.
Easy variations
- Veggies: Swap the green beans for mixed vegetables, corn, or peas and carrots.
- Soup: Cream of chicken or cream of celery works in place of cream of mushroom.
- Meat: Ground turkey or sausage both work. Brown sausage first.
- Onion: Brown a diced onion with the beef for more flavor.
- Cheese: Cheddar is the classic choice. If you’re dairy-free, skip it or use a dairy-free shred.
Making it dairy-free
Cream of mushroom soup has milk in it, so it’s the main thing to change if you’re lactose intolerant or dairy-free. You have two good options. Look for a dairy-free condensed soup at the store, or make a quick one at home: cook sliced mushrooms in a little oil, stir in a couple tablespoons of flour, and slowly whisk in broth and unsweetened plant milk until it’s thick. Season with salt, pepper, and garlic powder.
What to serve with it
This is a full meal in one pan, so you don’t need much. A simple green salad or sliced fruit is plenty. And yes, ketchup on the side is still my recommendation. If you like this, try my Mexican cornbread casserole for another easy weeknight dinner.
Frequently asked questions
Do I have to brown the ground beef first for tater tot casserole?
No, but it helps. Raw beef pressed into the pan will cook in the oven, it just takes longer, often 45 minutes to an hour at 400 degrees F. Browning and draining it first cuts the bake time to about 30 to 35 minutes, until the tots are crisp, and gets rid of extra grease. Either way, the beef should reach 160 degrees F.
How do I make tater tot casserole dairy-free?
Use a homemade or store-bought dairy-free cream of mushroom soup, or thicken a cup of broth and a little unsweetened plant milk with flour and cook in sauteed mushrooms. Leave off the cheese or use dairy-free shreds. Check the tater tot bag too, since most plain tots are dairy-free but some seasoned ones are not.
Can I make tater tot casserole ahead of time?
Brown the beef and assemble the beef, soup, and green bean layers up to a day ahead, cover, and refrigerate. Add the frozen tots right before baking so they stay crisp, and give it a few extra minutes in the oven since the pan starts cold. Don't assemble it ahead with raw beef.
How long do leftovers last?
Refrigerate leftovers within two hours in a covered container and eat them within three to four days. Reheat in a 375 degree F oven or air fryer to bring back some crunch, since the microwave makes the tots soft.
