Step‑by‑Step Instructions for Creamy One-Pot Beef and Potato Casserole

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). Meanwhile, gather a large skillet and heat it over medium-high heat. As the skillet warms, this is a great time to finely chop your onion, preparing it for the sautéing process that will build the dish’s flavor foundation.

Step 2: Sauté the Beef and Onion
Add the ground beef and chopped onion to the hot skillet, using a wooden spoon to break up the meat as it browns. Sprinkle in salt, black pepper, and paprika, cooking for about 5-7 minutes until the beef is no longer pink and the onions are soft and translucent. Drain any excess fat before moving on to the next step.

Step 3: Create the Creamy Mixture
In a mixing bowl, combine the cream of mushroom soup, whole milk (or heavy cream), and sour cream if using. Whisk these ingredients together until smooth and creamy, ensuring there are no lumps. This velvety mixture is going to infuse the casserole with rich flavors in the next steps.

Step 4: Assemble the Casserole
Spread the browned beef and onion mixture evenly in a greased 9×13 baking dish, forming the first layer of your Beef and Potato Casserole. This will create a hearty base for the casserole. Ensure the beef mixture is distributed uniformly for optimal flavor in every bite.

Step 5: Layer the Potatoes
Next, take your thinly sliced potatoes and layer them evenly atop the beef mixture. Overlapping the slices slightly is perfectly fine; aim for a visually appealing look. The potato layer will add a comforting texture, giving the casserole its signature heartiness.

Step 6: Pour the Creamy Sauce
Gently pour the creamy mixture you prepared earlier over the layered potatoes, making sure to cover them completely. A spatula can help spread the sauce for even coverage, creating a luscious base that melds all the flavors together beautifully as the casserole bakes.

Step 7: Add Cheese Topping
Generously sprinkle shredded cheddar cheese on top of the casserole, allowing it to create a golden, melty layer as it cooks. This layer not only enhances the savory goodness but also provides a delightful contrast to the creaminess beneath.

Step 8: Bake with Foil
Cover the assembled casserole with aluminum foil to retain moisture during baking. Place it in the preheated oven and bake for 45 minutes. This initial baking time allows the flavors to develop and the potatoes to soften beautifully.

Step 9: Uncover and Finish Baking
After 45 minutes, carefully remove the foil and return the casserole to the oven. Bake it for an additional 15 minutes, allowing the cheese to bubble and turn a delicious golden color. You’ll know it’s ready when the cheese has melted and appears irresistibly inviting.

Step 10: Rest and Garnish
Once the casserole is bubbly and golden, take it out of the oven and let it rest for 5-10 minutes before serving. This step helps the layers set, making it easier to serve. Sprinkle with fresh parsley for a pop of color and a hint of freshness to this comforting Beef and Potato Casserole.

What if my potatoes are not cooking evenly in the casserole?
If you notice that the potatoes aren’t cooking uniformly, it’s often due to uneven slicing. Make sure they’re cut about 1/8 inch thick for even cooking.
