Cheesy Ground Beef & Potato Casserole

Step 1: Preheat the Oven [00:00]

Preheat the oven to 375°F and lightly grease a 9×13-inch baking dish with butter.

Step 2: Prepare the Potatoes [00:30]

Peel the potatoes and slice them into thin, even rounds so they cook uniformly and become tender throughout the casserole.

Step 3: Cook the Ground Beef [01:00]

Heat a large skillet over medium-high heat, add the ground beef, and cook for 6–8 minutes while breaking it into small crumbles.

Step 4: Add Vegetables [01:30]

Add the diced onion and sliced mushrooms to the beef and cook for another 5–6 minutes until the vegetables soften and the beef is nicely browned.

Step 5: Season the Mixture [02:00]

Stir in the minced garlic, paprika, Italian seasoning, salt, and black pepper, then cook for 1 minute until fragrant.

Step 6: Prepare the Creamy Sauce [02:30]

Remove the beef mixture from the skillet and set it aside while preparing the creamy sauce in the same pan. Melt the butter over medium heat, whisk in the flour, and cook for 1 minute to form a smooth roux.

Step 7: Add Liquids [03:00]

Gradually whisk in the beef broth and heavy cream until smooth, then add the Worcestershire sauce and Dijon mustard.

Step 8: Simmer the Sauce [03:30]

Simmer the sauce for 3–5 minutes, stirring constantly, until it becomes thick enough to coat the back of a spoon.

Step 9: Layer the Casserole [04:00]

Arrange one layer of sliced potatoes in the prepared baking dish, slightly overlapping the slices, then season lightly with a little salt and pepper. Spread half of the seasoned ground beef and mushroom mixture over the potatoes, followed by half of the cheddar and mozzarella cheese.

Step 10: Repeat Layers [05:00]

Repeat with the remaining potatoes and beef mixture, then pour the creamy sauce evenly over the entire casserole so it reaches down between the potato layers.

Step 11: Bake Covered [06:00]

Cover the dish tightly with foil and bake for 45–50 minutes, until the potatoes are almost completely tender.

Step 12: Bake Uncovered [07:00]

Remove the foil, sprinkle the remaining cheddar and mozzarella evenly over the top, and bake uncovered for another 20–25 minutes until bubbling, golden, and deeply melted.
