This potato casserole delivers creamy comfort in every bite, with layers of tender potatoes and rich mushroom sauce baked to golden perfection. It’s a dish that transforms simple ingredients into something truly satisfying.

What sets this recipe apart is the creamy base of cream of mushroom soup, which melts into the potatoes as they bake. A sprinkle of cheese on top adds a gooey, golden crust that’s impossible to resist.

Serve it alongside a crisp salad or steamed vegetables for a complete meal. Here’s how to make it.

Ingredients for Potato Casserole Recipe with Cream of Mushroom Soup

Simple pantry ingredients transform into this creamy, comforting baked dish.

The potatoes are the foundation here. Russets hold up best to baking and soak up the creamy sauce beautifully. Look for firm, unblemished potatoes at your local grocery store. The cream of mushroom soup is key—Campbell’s is standard, but store brands work too. For the cheese, sharp cheddar gives the best melt and flavor punch.

Need a swap for sour cream? Greek yogurt works at a 1:1 ratio. No cheddar? Monterey Jack melts just as well. Want extra mushroom flavor? Add sautéed fresh mushrooms between the layers. For a gluten-free version, use gluten-free cream of mushroom soup and skip the flour. The onion can be yellow or white—whatever you have.

Assemble this the night before and refrigerate—just add 10-15 minutes to the baking time. Leftovers keep well for 4-5 days in the fridge or freeze for up to 3 months (reheat in the oven for best texture).

Step-by-Step Instructions for Creamy Potato Casserole

This method delivers rich, comforting layers with a perfectly golden top every time.

Step 1: Prepare and Parcook the Potato Slices

Peel the 3 lb Russet Potatoes and slice them ⅛-inch thick using a sharp knife or mandoline. Consistency in thickness ensures even cooking. Place the slices in a large pot of salted boiling water and parcook for 5-6 minutes until just beginning to soften but still holding their shape.

Drain the potatoes thoroughly and pat them dry with a clean towel. This step removes excess starch and moisture, which prevents a gummy texture in your finished casserole. I always taste a slice at this point—it should be tender but firm.

Step 2: Build the Creamy Soup and Cheese Base

In a large bowl, whisk together the 2 cans Cream of Mushroom Soup, 1 cup Sour Cream, 1 tsp Salt, 0.5 tsp Black Pepper, 1 tsp Dried Thyme, and 0.5 tsp Paprika until smooth. The soup should be fully incorporated with no visible streaks.

Stir in 1.5 cups Shredded Cheddar Cheese, reserving the remaining 0.5 cup for the topping. The mixture will be thick and luxurious—this is the heart of your casserole’s creamy texture. I use sharp cheddar for its bold flavor that stands up to the rich soup base.

Step 3: Layer Potatoes with Onion and Garlic Mixture

Finely dice the 1 whole Yellow Onion and mince the 3 cloves Garlic Cloves. In a small pan, melt 2 tablespoons of the 0.5 cup Unsalted Butter over medium heat and sauté the onion and garlic for 3-4 minutes until soft and translucent.

Begin layering in a greased 9×13-inch baking dish: start with half the parcooked potatoes, then spread half the onion-garlic mixture, followed by half the soup mixture. Repeat the layers, ending with the remaining soup mixture. This distribution ensures every bite has balanced flavor.

Step 4: Top and Bake to Golden Perfection

Melt the remaining butter and mix it with the reserved 0.5 cup Shredded Cheddar Cheese and 0.25 cup All-Purpose Flour to create a streusel-like topping. Sprinkle this evenly over the casserole—it will form a crisp, golden crust as it bakes.

Bake at 375°F for 35-40 minutes until the top is deep golden brown and the edges are bubbling. Let it rest for 10 minutes before serving; this allows the layers to set and makes for cleaner slices. The rest time also lets the flavors meld together beautifully.

Wine and Beer Pairings for This Recipe

White Wine Pairings

A crisp Chardonnay with its buttery notes complements the creamy texture beautifully. I prefer unoaked versions from California like Kendall-Jackson Avant—its bright acidity cuts through the richness. Serve chilled at 45-50°F for best results. 🍷

Red Wine Options

For red lovers, a light Pinot Noir works surprisingly well. The Burgundy region produces excellent options with earthy notes that match the mushroom flavor. Meiomi from California offers great value at around $20 per bottle.

Craft Beer Choices

A malty Amber Ale like Fat Tire from New Belgium pairs perfectly with the dish’s richness. The caramel notes in the beer complement the cheesy topping. For a hoppier option, try a Brown Ale such as Dale’s Pale Ale. 🍺

Non-Alcoholic Pairings

Sparkling apple cider offers a refreshing contrast to the creamy casserole. I particularly like Martinelli’s for its crisp, clean finish. Serve over ice for an extra refreshing touch during warmer months.

Coffee Pairing

For a unique pairing, try a medium roast coffee with your meal. The acidity in a Colombian or Kenyan coffee cuts through the richness. I recommend Starbucks Reserve for this combination.
