This Sour Cream and Onion Smashed Potato Casserole is not only delightful in flavor but sets a warm tone at your family gatherings and dinners! Step‑by‑Step Instructions for Sour Cream and Onion Smashed Potato Casserole Step 1: Preheat the Oven Begin by preheating your oven to 375°F (190°C). This ensures that your Sour Cream and Onion Smashed Potato Casserole bakes evenly and develops a beautifully golden topping. While the oven warms up, gather your ingredients and prepare the potato mixture. Step 2: Prepare the Potatoes Peel and chop the russet potatoes into equally sized chunks. This will help them cook uniformly. Place them in a large pot of salted water and bring it to a boil. Allow the potatoes to cook for about 15–20 minutes, or until fork-tender. Drain the potatoes well and return them to the pot. Step 3: Mash the Potatoes Using a potato masher, mash the drained potatoes until smooth and creamy. Mix in the butter, sour cream, and a generous pinch of salt and pepper. The mixture should be velvety with a hint of tang from the sour cream. For added flavor, fold in the chopped green onions, which will brighten up your casserole. Step 4: Assemble the Casserole Transfer the creamy mashed potato mixture into a greased 9×13-inch casserole dish, smoothing the top with a spatula. If desired, sprinkle additional cheddar cheese evenly over the surface for an extra layer of richness. This layer will melt beautifully during baking, creating a satisfying crust. Step 5: Bake Until Golden Place the casserole in the preheated oven and bake for 25–30 minutes. Keep an eye on it; you want the top to turn a delightful golden brown, signaling that the cheese is bubbly and the flavors have melded together perfectly. This will enhance the savory notes of the Sour Cream and Onion Smashed Potato Casserole. Step 6: Cool Before Serving Once baked, remove the casserole from the oven and let it cool for about 5 minutes. This resting period helps the casserole set, making it easier to serve. Enjoy the warmth and comforting aroma filling your kitchen while preparing to dive into this delicious dish. Make Ahead Options These Sour Cream and Onion Smashed Potato Casserole are perfect for meal prep enthusiasts! You can prepare the creamy mashed potato base up to 24 hours in advance by following all the steps up to assembling the casserole. Just refrigerate the uncooked mixture in an airtight container. When you’re ready to bake, spread the mixture in a greased casserole dish, sprinkle with cheddar cheese, and place it directly into a preheated oven. For optimum quality, allow it to sit at room temperature for about 30 minutes before baking to ensure even cooking. This means less hassle on busy days while still enjoying a comforting, homemade dish that’s just as delicious!

Reheat in the oven at 350°F (175°C) until warmed through and the cheese is bubbly. Freezer: This casserole can be frozen for up to 2 months.
