Step‑by‑Step Instructions for Creamy One-Pot Beef and Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This warm temperature is essential for achieving a perfectly baked creamy one-pot beef and potato casserole. While the oven heats up, you can prepare your other ingredients, ensuring everything is ready for the cooking process ahead.
Step 2: Brown the Beef
In a large skillet over medium-high heat, add your ground beef along with the chopped onion, salt, black pepper, and paprika. Cook for about 7-10 minutes, stirring frequently, until the beef is browned and the onions are translucent. Drain any excess fat to keep the dish from becoming greasy, creating a flavorful base for your casserole.
Step 3: Make the Creamy Sauce
In a mixing bowl, combine the cream of mushroom soup, whole milk (or heavy cream), and sour cream. Whisk these ingredients together until they form a smooth and creamy mixture. This sauce will enrich your creamy one-pot beef and potato casserole, adding moisture and flavor, so make sure there are no lumps.
Step 4: Layer the Casserole
Grease a 9×13-inch baking dish to prevent sticking. Spread the cooked beef and onion mixture evenly along the bottom of the dish. Next, layer the thinly sliced potatoes on top of the beef, as this will help them cook evenly, absorbing all those wonderful flavors. Pour the creamy sauce over the potatoes, ensuring it covers everything generously.
Step 5: Add Cheese
Generously sprinkle the shredded cheddar cheese over the top of the layers. This added cheese will melt beautifully as it bakes and create that deliciously gooey texture we all love in a creamy one-pot beef and potato casserole. Be sure to cover all the potatoes for maximum cheesiness!
Step 6: Cover and Bake
Cover your baking dish tightly with aluminum foil to trap the moisture inside. Place the casserole in the preheated oven and bake for 45 minutes. This step allows the potatoes to cook through and absorb the flavors from the beef and creamy sauce. Keep an eye on it to ensure it doesn’t overbake.
Step 7: Uncover and Finish Baking
After 45 minutes, carefully remove the foil from the casserole, and return it to the oven. Bake uncovered for an additional 15 minutes until the top is golden and bubbly. This step will ensure a delightful crispness on the cheese while keeping the layers creamy beneath.
Step 8: Rest Before Serving
Once removed from the oven, let the creamy one-pot beef and potato casserole sit for about 5-10 minutes before serving. This brief resting period will help the layers set slightly, making it easier to dish out and ensuring you get all that delicious goodness in every serving.
