Tater Tot Casserole is an incredibly easy dish to make and everyone always loves it!

Layers of tater tots, meat and veggies are covered in a simple sauce and cooked until hot and bubbly.  It’s easy, creamy and oh so yummy!

The best part is, this tater tot casserole is so versatile depending on what is in your fridge!

I love casseroles from Unstuffed Cabbage Roll Casserole to Homemade Mac and Cheese, there’s just something so comforting about a hot and bubbly meal coming out of the oven.  While this easy Tater Tot casserole isn’t the prettiest dish ever, it definitely tastes amazing!

Of all of the versions out there, I definitely think this is the best Tater Tot casserole because it’s so easy to put together yet really delivers on flavor (well, this and of course Mexican Tater Tot Casserole).

I start with a layer of tater tots on the bottom of a slow cooker (I use a 4QT CrockPot for this recipe), and top it with a layer of ground beef.  I use frozen veggies right from the freezer meaning no prep required and then top with another layer of Tater Tots.

A quick and simple sauce is added with a bit of cheese and it all cooks to perfection in the CrockPot.  Easy peazy right?!

Once cooked, this Tater Tot Casserole is absolutely delicious and actually reminds me of a cottage pie (which is the same as Shepherd’s Pie with beef instead of lamb).  Surprisingly enough, cooking this in the slow cooker you still get the crusty bits on the edges (which is one of my favorite parts).

While I use frozen veggies, you can use fresh veggies in this recipe too!     The frozen makes it easy because they don’t require any prep, I just give them a quick rinse in a strainer and pour them into the slow cooker.  If you’re using fresh veggies, there is no need to pre-cook them, just dice them fairly small and they’ll cook along with the rest of the dish.

The whole dish will take you literally just minutes to put into your slow cooker and you can use whatever you have on hand! I’ve added lean ground beef and frozen vegetables into this tater tot casserole but use up any leftover beef, chicken or turkey you might have!

While I most often cook this in the slow cooker, of course Tater Tot Casserole can be baked in the oven to golden perfection as well.  Simply place the beef layer in a 9×13 pan (or any casserole dish will do) and top with veggies and then Tater Tots.  Sprinkle with cheese and sauce and bake at 400°F for about 30 minutes or until golden and bubbly.

This easy Slow Cooker Tater Tot casserole is a complete meal in itself but we usually serve with a nice fresh green salad and some crusty bread!

  1. I made the Tater Tot slow cooker recipe but my tater tots all cooked down so you could not see them. It was still delicious but I would have liked to have whole tots. Is it because I cooked on high?

    1. Hmmm, sounds like they may be overcooked Jolene. Did you cook on high for 3 or 4 hours? You may want to reduce the cooking time closer to 3hrs to see if that helps keep those yummy tater tots intact.

  2. I made this for dinner last night and my whole family loved it- my husband had two huge helpings!
    I was just curious if the serving size and nutrition information is accurate. When I did the math, I got a total calories amount of over 4,000…yours comes to around 2,400. Just want to make sure I’m budgeting for the right amount when eating this :)5 stars

    1. Thank you for letting me know Michelle, there was an error in calculation on our end. I apologize for the mistake, I’ve updated the recipe and it should read correctly now.

  3. My friend is allergic to mushrooms, so would it be ok if I used cream of chicken soup instead of cream of mushroom?

    1. I have only tried this recipe as written, but I am sure it would be delicious with cream of chicken soup. Let me know how it turns out!

  4. My family really enjoyed this meal and it was super easy. I like how you put the calories on the bottom, but not knowing the serving size made it difficult.

  5. Excellent! My family and I are vegetarians so I substituted beef with veggie meat. I also sautéed chopped onion, green pepper and more carrots to add with the frozen vegetables.5 stars

  6. Made two of these in the oven. One shredded chicken and one beef. Big hit, quick, easy, and a crowd pleaser. Thanks you for sharing.5 stars

  7. Why layer? You don’t layer Beef Stew or Chili in a Slow Cooker. I put everything in a mixing bowl, except the cheese, mixed and dumped in a 6 Qt. Slow Cooker. This filled the Slow Cooker to the top. I cannot see this fitting into a 4 Qt. I added the cheese during the last hour of cooking on LOW. It did settle after cooking. Sauce was too watery.
    Next time, I plan on using 2 lbs of ground beef or frozen meatballs and some fried mushrooms, 2 cans of soup with 1/2 cup of milk and some more veggies. Might be a tight fit in my 6 Qt., but I do have an 8 Qt. so it should fit.
    Other than that, this is a keeper.5 stars

    1. I layer because the bottom layer of the slow cooker gets a little bit crispy/crusty. The photos (and video) of this recipe were cooked in a 4qt slow cooker so it does fit in mine (which is round in shape).

      Love the idea of using meatballs, thank you for sharing!

    1. I have seen soy crumbles in the store (which are a beef substitute). I’ve only made this with beef so I can’t say for sure how it would work out for you, please let us know how it goes!
