Ingredients
1½ pounds ground beef
1 tablespoon olive oil
1 medium onion, finely chopped
3 cloves garlic, minced
1½ cups mushrooms, sliced
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon paprika
1 teaspoon Italian seasoning
½ cup diced tomatoes (canned or fresh)
4 medium potatoes, peeled and thinly sliced
1 cup beef broth
½ cup heavy cream (or milk, for a lighter option)
1½ cups shredded cheddar cheese
1 cup shredded mozzarella cheese
Fresh parsley, chopped (for garnish)
Instructions
Preheat and prep.
Preheat your oven to 375°F (190°C). Lightly grease a rectangular baking dish and set it aside.Brown the beef.
Heat olive oil in a large skillet over medium heat. Add the ground beef and cook until browned, breaking it apart as you go. Drain excess fat if needed.Add the veggies and flavor.
Stir in the chopped onion and cook for 3–4 minutes until softened. Add the garlic and mushrooms and cook another 2–3 minutes, until the mushrooms start to shrink and smell earthy and rich.
Season with salt, pepper, paprika, and Italian seasoning. Stir in the diced tomatoes, then take the skillet off the heat.Start layering.
Arrange half of the sliced potatoes in an even layer in your baking dish. Try to overlap them slightly, like shingles — it helps everything bake evenly.Add the first beef layer.
Spread half of the beef and mushroom mixture over the potatoes.Repeat the layers.
Add the remaining potatoes, then top with the rest of the beef mixture.Pour in the liquids.
Slowly pour the beef broth and heavy cream (or milk) evenly over the casserole. This is what helps the potatoes soften and soak up all that savory goodness.Add the cheese blanket.
Sprinkle the cheddar and mozzarella evenly over the top. Don’t be shy — this is the cozy part.Bake until tender and bubbly.
Cover with foil and bake for 45 minutes. Remove the foil and bake for another 15 minutes, until the cheese is melted, bubbling, and lightly golden.Rest, then slice.
Let the casserole rest for about 10 minutes before cutting. This helps it set up so the layers stay nice and neat.
Presentation
For that “straight from the oven” wow factor, bring the baking dish right to the table and sprinkle fresh parsley over the top. The green pop against the melted cheese is simple but pretty. If you want it to feel extra cozy, serve it with a crisp side salad or some steamed green beans — something fresh to balance the richness. And when you slice it, use a wide spatula so you get those layers of potato, beef, and cheese all in one dreamy scoop.
