This casserole is the kind of dish that wraps you in a warm hug. It’s built on layers of savory ground beef, thinly sliced potatoes, and a rich, velvety mushroom soup sauce—all crowned with bubbling cheddar cheese. Whether you’re feeding a hungry family, prepping for a potluck, or just craving something cozy, this one-pan wonder delivers. It’s simple, satisfying, and steeped in tradition, just like grandma used to make.


🧂 Ingredients (Serves 6–8):

  • 1 lb lean ground beef
  • 1 medium onion, finely chopped
  • 3–4 large russet potatoes, peeled and thinly sliced
  • 1 can (10.75 oz) condensed cream of mushroom soup
  • ½ cup milk
  • 1½ cups shredded cheddar cheese (divided)
  • 1 tsp garlic powder
  • ½ tsp black pepper
  • ½ tsp salt
  • 1 tbsp butter (optional, for greasing)
  • Fresh parsley for garnish (optional)

🔥 Instructions:

Step 1: Prep the Ingredients

  1. Preheat your oven to 375°F (190°C).
  2. Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
  3. In a large skillet over medium heat, cook the ground beef until browned and crumbly. Drain excess fat.
  4. Add chopped onion to the skillet and sauté until soft, about 3–4 minutes.
  5. Season the beef mixture with garlic powder, salt, and pepper. Set aside.

Step 2: Mix the Sauce

  1. In a bowl, whisk together the cream of mushroom soup and milk until smooth.
  2. Stir in ½ cup of shredded cheddar cheese for extra creaminess.

Step 3: Assemble the Casserole

  1. Layer half of the sliced potatoes evenly across the bottom of the baking dish.
  2. Spoon half of the beef mixture over the potatoes.
  3. Pour half of the soup mixture over the beef.
  4. Repeat the layers: potatoes, beef, soup.
  5. Cover the dish tightly with foil.

Step 4: Bake

  1. Bake covered for 45–50 minutes, or until the potatoes are fork-tender.
  2. Remove foil and sprinkle the remaining 1 cup of cheddar cheese over the top.
  3. Return to oven uncovered and bake for an additional 10–15 minutes, until the cheese is melted and bubbly.

Step 5: Serve

  1. Let the casserole rest for 5–10 minutes before serving.
  2. Garnish with chopped parsley if desired.
  3. Serve warm with a side of crusty bread or a fresh green salad.

🍽️ Tips & Variations:

  • Add veggies: Mix in frozen peas, corn, or green beans for extra color and nutrition.
  • Make it tropical: Add a hint of nutmeg or swap cheddar for Monterey Jack with pineapple salsa on the side.
  • Sugar-free twist: Use unsweetened almond milk and homemade mushroom sauce for a lighter version.
  • Make-ahead magic: Assemble the casserole a day ahead and refrigerate. Just bake when ready to serve.

This dish is more than just dinner—it’s a memory, a tradition, and a guaranteed crowd-pleaser.
