Ground Beef Potato Casserole

🥔 Ingredients

• 1 can (10.5 oz / 298 g) condensed cream of mushroom soup
• 1 cup sour cream
• ½ cup milk
• 1 tablespoon Worcestershire sauce
• 1 teaspoon paprika
• 1 teaspoon dried parsley
• ½ teaspoon dried thyme
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• 1 teaspoon salt, divided
• ½ teaspoon freshly ground black pepper
• 2 tablespoons olive oil or butter

Optional additions

• 1 cup sliced mushrooms
• ½ cup diced bell pepper
• ½ teaspoon smoked paprika
• 2 tablespoons chopped fresh parsley
• ¼ cup crispy fried onions for the topping
• A pinch of red pepper flakes for a little heat

🥣 Creamy Sauce

In a bowl, combine:

• Cream of mushroom soup
• Sour cream
• Milk
• Worcestershire sauce
• Garlic powder
• Onion powder
• ½ teaspoon salt
• Black pepper

Whisk everything together until smooth and creamy.

👩‍🍳 Instructions

1. Prepare the potatoes

Preheat your oven to 375°F (190°C).

Wash and thinly slice the Yukon gold potatoes. Aim for slices around ⅛ inch thick so they cook evenly.

You can peel them if you prefer, but leaving the skins on gives the casserole extra rustic flavor and texture.

Place the sliced potatoes in a bowl and toss gently with a little olive oil, paprika, thyme, and the remaining salt.

2. Brown the beef

Heat a large skillet over medium-high heat.

Add the ground beef and cook for about 6–8 minutes, breaking it apart with a spoon as it browns.

Add the diced onion and cook for another 3–4 minutes, until softened.

Add the minced garlic and cook for about 30 seconds.

Drain excess grease if necessary.

Stir in the Worcestershire sauce, paprika, dried parsley, black pepper, and optional smoked paprika.

Taste and adjust the seasoning.

3. Build the casserole

Lightly grease a 9 × 13-inch baking dish.

Arrange approximately half of the sliced potatoes across the bottom.

Spread half of the seasoned ground beef over the potatoes.

Spoon half of the creamy sauce over the beef.

Sprinkle with about half of the cheddar and Monterey Jack cheese.

Repeat the layers:

Potatoes → beef → creamy sauce → cheese

Finish with a generous layer of cheese on top.

4. Cover and bake

Cover the baking dish tightly with aluminum foil.

Bake at 375°F (190°C) for approximately 50–60 minutes.

The foil traps steam, helping the potatoes become tender without allowing the cheese to brown too quickly.

5. Finish uncovered

Remove the foil and continue baking for another 15–20 minutes, until the potatoes are completely tender and the cheese is melted, bubbling, and lightly golden.

For an extra-golden top, you can place the casserole under the broiler for 1–2 minutes, watching carefully so it doesn’t burn.

6. Rest before serving

Remove the casserole from the oven and let it rest for 10–15 minutes.

This short resting period allows the creamy sauce to settle and makes the casserole much easier to serve.

Sprinkle with fresh parsley if desired.

🍳 Cooking Method

The secret to this casserole is layering and slow baking.

The thinly sliced potatoes absorb the savory juices from the beef while baking. Meanwhile, the creamy sauce moves between the layers, creating a rich texture throughout the dish.

Browning the beef first is important because it develops deeper flavor and prevents the casserole from becoming watery.

The final uncovered baking stage allows excess moisture to evaporate and gives the cheese that delicious golden finish.

🕰️ A Little History

Potato-and-meat casseroles belong to a long tradition of practical home cooking. Across many countries, cooks have combined inexpensive potatoes with ground meat, onions, dairy, and cheese to create filling meals that could feed an entire family.

American-style casseroles became especially popular as convenient pantry ingredients and condensed soups became common in home kitchens during the 20th century.

This version brings together those classic ideas: humble potatoes, seasoned beef, creamy sauce, and melted cheese.

❤️ Why Everyone Loves It

There is something especially comforting about a bubbling casserole coming out of the oven.

The potatoes are soft and buttery, the ground beef is savory and flavorful, and the melted cheese creates a delicious golden layer on top. It’s also easy to customize according to whatever you have in the refrigerator.

Want more vegetables? Add mushrooms, peas, carrots, or bell peppers.

Want extra cheesiness? Add another handful of cheese.

Want a little spice? Add chili flakes or diced jalapeños.

🍽️ Serving Ideas

Serve this casserole with:

• A fresh green salad
• Steamed broccoli
• Roasted carrots
• Green beans
• Corn
• Garlic bread
• Crusty dinner rolls
• Pickles or a simple cucumber salad

For a cozy family meal, spoon generous portions onto plates and serve immediately while the cheese is still warm and stretchy.

🧊 Storage and Reheating

Allow leftovers to cool before covering and refrigerating.

Store in the refrigerator for up to 3–4 days.

To reheat, place individual portions in the microwave until hot, or cover the casserole with foil and warm it in a 350°F (175°C) oven until heated through.

The casserole can also be frozen in an airtight, freezer-safe container. For best texture, thaw it overnight in the refrigerator before reheating.
