- 1 can (10.5 oz) cream of mushroom soup: The creamy heart that binds all ingredients beautifully together.
- 1/2 cup whole milk or heavy cream: Gives the casserole a rich, silky texture.
- 1/2 cup sour cream (optional): For added tang and creaminess that elevates the sauce.
- 1 1/2 cups shredded cheddar cheese: A sharp, melty crust that finishes the dish with irresistible flavor.
- 1 tsp salt: Enhances all the flavors you’re about to enjoy.

How to Make Potato Casserole – Cozy & Simple Dinner
Step 1: Preheat and Prepare Your Oven
Start by preheating your oven to 375°F (190°C). This ensures it’s at the perfect temperature so the casserole bakes evenly and develops that golden top everyone loves.
Step 2: Cook the Beef and Onions
In a skillet over medium heat, brown the ground beef along with the chopped onions. Season with salt, black pepper, and paprika as you cook. This combination creates a savory flavor foundation. Make sure to drain any excess fat after cooking so the casserole doesn’t get greasy.
Step 3: Mix the Creamy Sauce
In a separate bowl, whisk together the cream of mushroom soup, whole milk (or heavy cream), and sour cream if you’re using it. This mixture will saturate the potatoes and beef, keeping everything moist and silky while baking.
Step 4: Assemble the Layers
Grease a 9×13 baking dish lightly to prevent sticking. Spread the cooked beef and onion mixture evenly on the bottom. Next, layer the thinly sliced potatoes over the beef to cover it completely. Pour the creamy sauce over the potatoes, making sure it seeps through all the gaps, infusing each slice.
Step 5: Add Cheese and Bake
Sprinkle the shredded cheddar cheese evenly on top for that mouthwatering golden crust. Cover the casserole tightly with foil and bake for 45 minutes. Removing the foil afterward allows the cheese to brown beautifully for an additional 15 minutes. Let the casserole rest for 5–10 minutes once out of the oven to finish setting up before serving.
How to Serve Potato Casserole – Cozy & Simple Dinner

Garnishes
Fresh parsley is an easy and elegant way to brighten up each serving of this rich potato casserole. It adds just the right touch of color and freshness to balance the creaminess and cheese.
Side Dishes
Think light and crisp to complement the hearty casserole. A simple green salad with a tangy vinaigrette, roasted vegetables, or even steamed green beans all pair wonderfully, creating a balanced meal without overwhelming the palate.
Creative Ways to Present
Want to impress friends or family? Serve this casserole in individual ramekins for charming personal portions or top each serving with a dollop of sour cream and chopped chives for extra flair. It’s the same cozy, simple dinner but elevated to restaurant style at your own table.
Make Ahead and Storage
Storing Leftovers
This potato casserole keeps beautifully in an airtight container in the refrigerator for up to 3 days. Allow it to cool completely before storing to preserve the creamy texture and prevent sogginess.
Freezing
You can freeze unbaked assembled casserole by covering it tightly with foil and plastic wrap to avoid freezer burn. It will last up to 2 months frozen. When ready to enjoy, bake it directly from frozen, just add extra baking time and keep it covered until fully hot.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 20–25 minutes or until heated through. Cover with foil at first to prevent over-browning, then uncover for the last few minutes to refresh that cheesy crust. Microwave works too but may make the potatoes softer.
FAQs
Can I use different types of potatoes for this casserole?
Absolutely! Russet and Yukon gold potatoes work best because they become tender without falling apart, but you can experiment with other varieties depending on your texture preferences.
Is sour cream necessary?
Sour cream is optional but highly recommended if you want extra creaminess and slight tang. You can leave it out or substitute with Greek yogurt for a lighter twist.
Can I make this casserole vegetarian?
Yes, simply skip the ground beef and add sautéed mushrooms, lentils, or a mix of your favorite vegetables to keep the dish hearty and satisfying.
What cheese works best if I don’t have cheddar?
Sharp cheddar gives the best flavor, but you can use Monterey Jack, mozzarella, or even a smoked gouda for different taste profiles.
How do I prevent the potatoes from drying out?
Make sure the creamy soup and milk mixture covers the potatoes well so they absorb moisture as they bake, keeping each layer tender and luscious.
