How to Make Cheesy Tater Tot Casserole
Step 1: Preheat and Prepare Your Pan
Start by preheating your oven to 375°F. Lightly grease a 9×13-inch baking dish with cooking spray—this little step ensures nothing sticks and makes cleanup a breeze.
Step 2: Brown the Ground Beef
In a large skillet over medium-high heat, brown the ground beef, seasoning it with salt, pepper, and that flavorful tablespoon of Worcestershire sauce. Once cooked through, drain excess fat and evenly spread the beef across the bottom of your prepared baking dish. This rich, meaty layer is the foundation of your casserole.
Step 3: Sauté the Veggies
Using the same skillet, toss in the diced onions and sliced mushrooms. Sauté for 4 to 5 minutes until they turn translucent and tender. Add the minced garlic and cook for another minute, stirring frequently to release its aromatic goodness. Don’t forget to season with salt and pepper to bring out their flavors.
Step 4: Make the Creamy Sauce
Sprinkle the flour over the cooked veggies in the skillet, stirring constantly to form a roux that will thicken your sauce. Slowly pour in the heavy cream, mixing as you go to combine everything smoothly. Let this simmer for about a minute while tasting and adjusting the seasoning. Then, reduce the heat and stir in the sour cream, creating a rich and tangy sauce that will coat each bite with creamy goodness.
Step 5: Layer Your Casserole
Pour the creamy mixture over the ground beef in the baking dish, spreading it evenly. Sprinkle two cups of shredded cheddar cheese over the top, then add the drained green beans in an even layer. Cover these veggies with the remaining two cups of cheddar cheese, making sure the cheese is distributed well for that perfect melt.
Step 6: Add the Tater Tots and Bake
Finally, arrange the frozen tater tots side by side over the top of the casserole, covering the surface completely. Pop the dish into your preheated oven and bake for 35 to 40 minutes until the tater tots are crispy and golden brown and the cheese beneath is bubbling with melty delight.
Step 7: Ready to Serve
Once baked, take your Cheesy Tater Tot Casserole out of the oven and let it rest for a few minutes before serving. This allows the layers to set slightly, making it easier to scoop out hearty portions that showcase all the delicious textures and flavors.
How to Serve Cheesy Tater Tot Casserole

Garnishes

Make Ahead and Storage
Storing Leftovers
Store any leftover Cheesy Tater Tot Casserole in an airtight container in the refrigerator. It will stay fresh for up to 3 days, making it a perfect meal prep or quick dinner option.
Freezing
To freeze, assemble the casserole but do not bake it. Cover tightly with foil and plastic wrap, then freeze for up to 3 months. When you’re ready, bake it straight from the freezer—just add extra baking time to ensure it’s heated through and bubbly.
Reheating
Reheat leftovers in the oven at 350°F for about 15-20 minutes until warmed through, or use the microwave for a quicker option. Adding a sprinkle of extra cheese before reheating can help revive that fresh, gooey feel.
FAQs
Can I use frozen green beans instead of canned?
Absolutely! Just be sure to thaw and drain them well before layering to avoid extra moisture that could make the casserole soggy.
What cheese works best for Cheesy Tater Tot Casserole?
Sharp cheddar is classic and gives the best flavor, but feel free to mix in mozzarella or Monterey Jack for extra meltiness and gooey texture.
Can I make this vegetarian?
Yes! Substitute the ground beef with cooked lentils or a plant-based meat alternative, and use vegetable broth or seasoning to maintain flavor in the creamy sauce.
How spicy is this recipe?
This casserole is mild and comforting as written, but you can add some crushed red pepper flakes or cayenne for a little kick if that’s your style.
Can I prepare this dish in advance?
Definitely! You can assemble the casserole a day ahead, cover it, and store it in the fridge. Just bake it fresh right before serving for the best results.
