Cheesy Ground Beef and Potato Casserole

A comforting, budget-friendly casserole with layers of potatoes, seasoned ground beef, creamy soup, and bubbling cheddar.

Ingredients

  • 1 lb ground beef (85/15)
  • 4 medium potatoes, thinly sliced (Yukon Gold or Russet)
  • 1 onion, chopped
  • 2 cups shredded cheddar cheese
  • 1 can cream of mushroom soup (10–11 oz)
  • 1 cup milk (whole or 2%)
  • Salt and pepper to taste
  • Olive oil for cooking

Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×13 casserole dish with olive oil.
  2. Heat a drizzle of olive oil in a skillet over medium heat. Add the chopped onion and cook until translucent, about 4–5 minutes.
  3. Add the ground beef, breaking it up with a spoon. Cook until no pink remains. Season with salt and pepper. Drain excess fat if desired.
  4. In a large bowl, whisk together the cream of mushroom soup and milk until smooth. Taste and adjust seasoning.
  5. Layer half of the potato slices in the prepared dish in an even layer. Top with half of the beef mixture and half of the cheddar cheese. Pour half of the soup mixture evenly over the layers.
  6. Repeat with the remaining potatoes, beef, cheese, and soup mixture, finishing with cheese on top.
  7. Cover the casserole tightly with foil and bake for 45 minutes.
  8. Remove the foil and bake an additional 15 minutes, until the potatoes are tender and the cheese is bubbly and starting to brown.
  9. Let the casserole rest for 5–10 minutes before slicing and serving.

Notes

Substitutions: Use ground turkey or chicken for a lighter version. For a creamier base, swap half-and-half for milk.
