TATER TOT CASSEROLE WITH GREEN BEANS

Unlike the others, this champ features a creamy homemade cream of mushroom sauce that comes together quick and easy.

TATER TOT CASSEROLE INGREDIENTS
- Tater Tots – You will need a package of frozen tater tots — just about any 28-32 ounce package is fine. You can add them to the casserole thawed or frozen, but remember, you’ll be adding them in two separate additions. If you like your tater tots extra crispy, snag a bag of Ore-Ida’s Extra Crispy Tater Tots. That’s our fave.
- Cheddar Cheese – If you’re short on time, feel free to use a high-quality bag of shredded Cheddar cheese. However, if time allows, freshly grated cheese is always best as far both texture and flavor are concerned.
- Ground Beef – You can use 80/20 or lean ground beef. Just be sure to rid of the grease before adding it to the casserole, especially if you’re using the same pan to make the cream of mushroom sauce.
- The Produce – Tater Tot Casserole is a full dinner with vegetables included! It features a combination of the following produce: yellow onions, fresh button mushrooms, and frozen green beans. Frozen green beans retain better flavor and texture than those from in a can, however, if you’d prefer to use canned green beans, feel free to do so.
- Flour – You will need all-purpose flour to thicken the sauce.
- Chicken Broth – The chicken broth is used to make up the body of the sauce for your Tater Tot Casserole. Be sure to buy unsalted or low sodium chicken broth or your casserole will likely be far too salty.
- Half-and-Half – For an extra decadent cream of mushroom sauce, bring on the half-and-half. You could use cream or whole milk in its place if desired.
- Seasoning – Kosher salt, black pepper, garlic powder, onion powder, and soy sauce are items you’ll want to have on hand to add big flavor to your Tater Tot Casserole! Soy sauce may seem like a strange ingredient, but you will find it brings out the umami flavor of the mushrooms and makes for one deliciously savory addition to the sauce.
HOW TO MAKE TATER TOT CASSEROLE
- Cook the Ground Beef – Add the beef, salt, and pepper to a large pan, break it apart, and cook it until no longer pink. Then, transfer the beef to a colander and wipe the pan clean.
- Make Cream of Mushroom Sauce – To make the homemade cream of mushroom sauce for your Tater Tot Casserole, you’ll begin by adding butter to the pan, along with the chopped onions and mushrooms and cook through. Sprinkle over the flour and add the chicken broth one big splash at a time, stirring well after each addition. Stir in all of the half-and-half and simmer briefly, until slightly thickened. Add just under half of the Cheddar, as well as the remaining seasoning to finish off the sauce.
- Assemble Casserole – Add the green beans, half of the tater tots, and the strained ground beef to the sauce and transfer to a greased casserole dish and scatter the remaining tater tots across the top.
- Bake – Bake for 25 minutes, then remove the casserole dish from the oven, add the remaining Cheddar cheese and bake for an additional 10 minutes.
HOW LONG TO COOK TATER TOT CASSEROLE
The best part of Tater Tot Casserole just might be the layer of crispy tater tots hiding beneath a sea of stretchy, creamy Cheddar Cheese. However, if you want those tater tots to actually end up crispy, you’ll have to cook them for a stint in the oven before you add the cheese.
Make sure the oven has been preheated to 375°, then add the casserole uncovered and bake for 25 minutes. After the time is up, pull the casserole from the oven, add the cheese and bake for an additional 10 minutes. This gives you a grand total of 35 minutes of cook time for Tater Tot Casserole.
CAN I MAKE TATER TOT CASSEROLE AHEAD OF TIME?
If you’d like to get a jump start on dinner, assemble the Tater Tot Casserole almost completely, leaving out only the last layer of cheese. Then, just cover and refrigerate up to a day in advance.
Since the casserole will likely be going into the oven cold, you will need to add 10-15 minutes to the initial cook time. Once you see the sides of the casserole are bubbling, the center is warm, and the tots are looking crispy, you can top it with the remaining cheese and finish cooking as directed.
