Hearty Casserole

A filling casserole with ground beef, potatoes, and cheese, ready in under an hour. Perfect for busy nights.

This casserole starts with ground beef browned in the same pan you bake it in. Less washing up, more flavor.

The potatoes soak up the beef juices as they cook. You want them thin so they soften in time.

It's done when the cheese bubbles and the edges turn golden. Let it sit five minutes before serving so it holds together.

About the Ingredients

1 lb (450g) ground beef

80% lean works best. Turkey works if you drain the fat well.

3 medium potatoes (about 1.5 lbs/680g)

Slice them 1/4 inch thick. No need to peel unless you prefer it.

1 cup (120g) shredded cheddar

Pre-shredded melts fine, but block cheese gives a creamier texture.

1 onion, diced

Yellow or white. Swap for a teaspoon of onion powder in a pinch.

1 can (10.5 oz/298g) condensed cream of mushroom soup

The liquid helps cook the potatoes. Celery or chicken soup works too.

1/2 cup (120ml) milk

Whole milk makes it richer. Water thins the sauce too much.

Frequently Asked Questions

Q: Can I use fresh mushrooms instead of soup?

Yes, but sauté them first with the beef. Add 1/2 cup broth to replace the soup’s liquid.

Q: Why are my potatoes still hard?

Slice them thinner—no more than 1/4 inch. They need direct contact with the sauce to soften.

Q: Can I make it ahead?

Assemble it the night before. Add 10 minutes to the baking time if starting cold.

Q: What’s the best cheese substitute?

Swiss melts well, or skip cheese and stir a cup of sour cream into the sauce instead.

Step-by-Step Instructions

1. Brown the beef

Cook beef and onion in a large skillet over medium heat until no pink remains, about 8 minutes. Drain fat but leave a tablespoon for flavor.

2. Mix the sauce

Stir in soup and milk until combined. This thins the soup into a sauce that coats everything.

3. Layer potatoes

Arrange potato slices evenly over the beef. They’ll steam in the sauce as it bakes.

4. Top with cheese

Sprinkle cheese evenly over the top. It’ll melt into gooey pockets.

5. Bake covered

Cover with foil and bake at 375°F (190°C) for 25 minutes. The foil traps steam to cook the potatoes.

6. Bake uncovered

Remove foil and bake another 10 minutes until the cheese bubbles and browns at the edges.

Tips & Tricks

  • Pat the beef dry before browning so it sears instead of steaming.
  • Layer potatoes evenly so they cook through. Overlapping is fine.
  • Cover with foil the first 25 minutes to steam the potatoes, then uncover to brown the top.

Delicious Variations

  • Swap half the potatoes for frozen mixed veggies
  • Add a teaspoon of smoked paprika to the beef
  • Top with crushed crackers for extra crunch
