Vegetable Tater Tot Casserole

Jump to Recipe
Spread the love

This vegetable tater tot casserole is the epitome of comfort food. Styled as a “chicken pot pie” it has all the flavor without the meat.

Casseroles are pretty much standard comfort food, and a midwest staple I have been informed by my friend Amanda over at Midwest Nice. Casseroles tend to have meat in them (from what I have seen), so, as I live with a pescetarian, I decided to make this comfort food classic safe for vegetarians. I now introduce you to the vegetable tater tot casserole.

What do you need for a vegetable tater tot casserole?

You will need the following for your cassrole:

  1. 4 celery stalks (chopped up finely)
  2. 1 small onion chopped finely (a yellow sweet onion is best)
  3. 1.5 cup mushrooms - cremini are fine (sliced up)
  4. 5 tablespoon gluten free flour (or regular flour, this is a 1:1 recipe)
  5. 3 tablespoon butter
  6. 2 tablespoon olive oil
  7. 4 large carrots chopped up or a bag of shredded carrots
  8. 1 tablespoon vegetable bouillon (this is my fave brand)
  9. 2.5 cups milk (I used 2% for a richer and heavier casserole, you can use whole milk- or for a less rich you can use 1 %)
  10. 3 or 4 thyme sprigs
  11. Enough tater tots to cover the top of the vessel you are using to bake your casserole in. You can use a cast iron pan (as I have here) or a baking dish. Your choice!

How do you make your vegetable tater tot casserole?

To begin:

  1. Set your oven to 400°F
  2. Chop up all of your vegetables and put them into a bowl. In the meantime, melt your butter and oil together in a pot.
  3. Once the butter has melted, add your vegetables to the put, stir to make sure that they have all been covered with the butter. As soon as they have, cover the pot with a lid.
  4. Check every few minutes to stir but you are going to sweat your veggies for about 10-15 minutes. You want to make sure that they are really soft.
  5. You will then add your flour, make sure to coat all of your vegetables.
  6. Add half of your milk, and stir your vegetables. It will begin to thicken. Once thick, add the rest of your milk.
  7. Once you have stirred your mixture and it appears to be thickening, add your vegetable bouillon. You also now want to add the thyme, and any salt or pepper you wish to add.
  8. Allow this mixture to sit on medium for about 10 minutes.
  9. Transfer to the dish in which you will cook it in, and cover with tater tots.
  10. Place your vegetable tater tot casserole in the oven and bake for 30 minutes.
  11. When done, remove from oven and allow to stand for 5-10 minutes prior to serving.

Why should you make this?

Whether it is cold or warm outside, if you are craving comfort food, this is it. The creaminess of the filling along with the crisp top of the tots makes this vegetable tater tot casserole an instant classic. The best part? If you are having dinner guests, it is super easy and can accommodate gluten free, vegetarian, and pescetarian diets. As Michael Scott would say, a win win win.
