4-Ingredient Hamburger Potato Casserole with Cheddar Soup

This oven-baked hamburger and potato casserole turns four pantry-friendly ingredients into a hearty family dinner. Thin potato slices soften beneath seasoned-by-the-soup ground beef, while cheddar soup makes the layers creamy and shredded cheese gives the top a golden finish. The key is to slice the potatoes thinly and keep the dish covered until they are nearly tender.

What you need

This recipe serves 6 to 8. Set out a 9 × 13-inch glass casserole dish, a large skillet, foil, and a sharp knife or mandoline.

• 2 pounds russet potatoes, sliced about 1/8 inch thick
• 1 pound ground beef
• 1 can (10.5 ounces) condensed cheddar cheese soup
• 1 1/2 cups shredded cheddar cheese

The cheese soup supplies the sauce and saltiness, so no additional seasoning is required for the four-ingredient version. If you prefer a more pronounced flavor, see the optional ideas below.

Before you start

Preheat the oven to 375°F (190°C). Lightly grease the glass dish. Peel the potatoes if you prefer a smoother texture, then cut them into even, thin rounds. Thick slices can stay firm after the cheese has browned, so aim for roughly 1/8 inch throughout.

How to make hamburger potato casserole

1. Brown the beef

Place the ground beef in a large skillet over medium heat. Break it into small crumbles as it cooks. Continue until no pink remains, then drain any excess fat. Let the beef cool briefly while you arrange the first layer of potatoes.

2. Build the layers

Arrange half of the potato slices across the bottom of the prepared dish, overlapping slightly. Spread half of the cooked beef over them. Dot half of the condensed cheddar soup across the beef; use the back of a spoon to spread it as evenly as possible. Scatter over half of the shredded cheese. Repeat with the remaining potatoes, beef, soup, and cheddar. An even top layer helps the casserole cook and brown uniformly.

3. Bake covered, then uncovered

Cover the dish tightly with foil and bake for 60 minutes. Carefully remove the foil, keeping your hands away from the hot steam. Bake for another 20–30 minutes, until a knife slides easily through the center potatoes and the cheese is bubbling and lightly golden. If the top darkens before the potatoes soften, cover it loosely again and continue baking.

4. Rest and serve

Let the casserole stand for 10–15 minutes. Resting helps the creamy layers settle so the portions lift more neatly. Cut into six or eight servings and offer a crisp green salad, green beans, or peas alongside.

Variations & Tips

• Choose the potatoes: Russets soften into a tender, creamy bake. Yukon Gold potatoes also work and hold their shape a little better.
• Use sharp cheddar: It adds a tangier finish without increasing the ingredient count.
• Add onion if desired: Cook one small chopped onion with the beef. This makes it a five-ingredient dish.
• Watch the top: Glass dishes can continue to brown the edges after the foil comes off. Cover loosely if needed.
• Check the center: Test the middle with a knife rather than judging by the bubbling edges.

Make-ahead and leftovers

For a head start, brown the beef up to a day ahead and refrigerate it in a covered container. Slice the potatoes close to assembly so they do not discolor. Refrigerate leftovers promptly in an airtight container for up to 3–4 days. Reheat until hot throughout; add a splash of water if the sauce has thickened.

Frequently asked questions

Do I dilute the condensed soup?

No. Use it straight from the can for this version; the potatoes release moisture as they bake and the covered dish retains steam.

Why are my potatoes still firm?

The slices may be too thick or the foil may not have sealed well. Cover the dish again and bake until the center is easily pierced.

Can I use a different cheese soup?

Yes, but check its saltiness and thickness. The sauce and final texture can vary by brand.
