This is my go-to hamburger potato casserole recipe, and it never lets me down.

This casserole is exactly the kind of dinner I grew up eating, ground beef, potatoes, and cheese, layered together and baked until everything is tender and bubbling. There’s nothing fancy about it, and that’s really the whole point.

I still make this on cold nights when I want something genuinely filling and familiar. It feeds a crowd, reheats beautifully, and never fails to disappear fast.

Why You’ll Love This Recipe

A few reasons this stays a family favorite.

Genuinely filling: beef and potatoes make this a real dinner.
Familiar, comforting flavor: nothing complicated here.
Feeds a crowd: perfect for a hungry family.
Great for meal prep: reheats well for leftovers.

Why This Works

Slicing the potatoes thin and even, rather than leaving them thick or irregular, is what ensures they cook through fully in the same time as the beef and cheese on top. Thick or unevenly cut potatoes end up with a raw, hard center by the time the top layer is already golden and bubbling.

Step-by-Step

Brown the ground beef with the chopped onion in a skillet over medium heat, breaking it apart as it cooks. Season with salt, pepper, and garlic powder, then drain excess fat.

Ground beef and onion browning in a skillet — Brown the beef fully and drain excess fat before layering.

Slice the potatoes thin and even, about an eighth of an inch thick, a mandoline makes this fast and consistent. Layer half the sliced potatoes in the bottom of a greased baking dish.

Spread the seasoned beef evenly over the potatoes, then top with the remaining potato slices. Pour the beef broth evenly over the top, this keeps the potatoes from drying out as they bake.

Sliced potatoes and beef layered in a baking dish — Slice the potatoes thin and even for the best texture.

Cover tightly with foil and bake at 375 degrees for 50 minutes, until the potatoes are fork-tender. Remove the foil, top with shredded cheddar, and bake uncovered for another 10 minutes, until melted and golden.

Let the casserole rest for 10 minutes before serving, this helps it hold together when scooped.

Frequently Asked Questions

Can I use pre-sliced potatoes to save time?

Yes, though slicing them yourself lets you control the thickness, which matters for even cooking.

Why are my potatoes still hard after baking?

They were likely sliced too thick, aim for about an eighth of an inch for potatoes that cook through fully.

Can I make this ahead and freeze it?

Yes, assemble without the final cheese layer, freeze, then thaw and add cheese during the last 10 minutes of baking.
