Ingredient notes
Ground beef – Choose lean ground beef for less grease, or substitute ground turkey. Thinly shaved steak can also be used for an even closer cheesesteak flavor.
Bell peppers – Green bell pepper is classic, but red, yellow, or orange peppers add color and sweetness.
Cheese – Shredded mozzarella melts nicely; provolone or cheddar are great alternatives depending on the flavor you want.
Tater tots – Use frozen tater tots for convenience. Shredded hash browns are an acceptable swap if you prefer.

How to make Philly cheesesteak tater tot casserole
- Preheat the oven to 425°F. In a large skillet over medium-high heat, melt butter and add the ground beef. Brown the beef until it is nearly cooked through.
- Stir in the diced sweet onion, bell pepper, and sliced mushrooms. Cook until the vegetables are softened and fragrant.
- Add the beef broth and a packet of brown gravy mix. Stir to combine and let the mixture thicken slightly.
- Spread the meat and vegetable mixture in the bottom of a greased 9×13-inch baking dish.
- Top the meat mixture with shredded cheese, then arrange frozen tater tots in a single layer across the surface.
- Bake at 425°F for about 30 minutes, or until the casserole is bubbling, the cheese is melted, and the tater tots are golden and crispy. Remove from the oven, garnish with chopped fresh parsley, and serve.

Serving suggestions
This casserole is a complete meal on its own, but it pairs nicely with a simple green salad and crusty bread. For extra vegetables, serve roasted carrots or Brussels sprouts on the side.
Storage
Refrigerate leftovers in an airtight container for 3–4 days. Reheat in a 350°F oven until warmed through or microwave in 1-minute intervals until hot.
How to freeze
Cool the baked casserole completely, then wrap tightly in plastic wrap and aluminum foil, or place in an airtight freezer container. Freeze up to 2–3 months. Thaw overnight in the refrigerator and reheat in a 350°F oven for 15–20 minutes or until the internal temperature reaches 165°F.

Frequently asked questions
Why is my tater tot casserole soggy?
Make sure you bake it long enough so excess moisture evaporates and the tots crisp. If needed, broil the top for a couple of minutes at the end to get extra browning.
Is tater tot casserole a Midwest thing?
Tater tot casseroles, often called “hot dishes,” are closely associated with Midwestern cooking, though they are popular across the country now.
Recipe tips & tricks
- Brown and season the ground beef well, then drain excess fat to prevent a greasy casserole.
- Cook the vegetables until just tender so they finish cooking in the oven without becoming mushy.
- Enhance flavor with a pinch of onion powder or a splash of Worcestershire sauce.
- For a creamier texture, stir in a bit of cream cheese or sour cream, or use cream of mushroom soup in place of fresh mushrooms.
- Try provolone slices instead of shredded mozzarella for a more authentic cheesesteak profile.
- If the top browns too quickly, tent with foil and remove it for the last few minutes of baking. Let the casserole rest 5 minutes before serving.
