Why This Creamy Potato Casserole Recipe Works
This isn’t just any potato dish – it’s a carefully crafted casserole that brings together the best elements of scalloped potatoes, potato gratin, and loaded mashed potatoes. The result? A creamy, dreamy potato side dish that pairs perfectly with anything from roast chicken to grilled steak, or even stands proudly on its own as the star of the meal.
What makes this potato casserole unique is the combination of different potato varieties, a homemade cream sauce that doesn’t separate during baking, and the perfect amount of cheese that creates that irresistable golden crust on top. The herbs and seasonings are balanced to enhance, not overpower, the natural flavor of the potatoes.
Ingredients for the Perfect Creamy Potato Casserole
Now, let’s take a look at what you’ll need to create this amazing dish:
For the Potato Base:
- 3 pounds (about 6-7 medium) Yukon Gold potatoes, sliced 1/8-inch thick
- 1 large onion, thinly sliced
- 4 cloves garlic, minced
- 2 tablespoons unsalted butter for greasing the baking dish
For the Cream Sauce:
- 2 cups heavy cream
- 1 cup whole milk
- 2 tablespoons all-purpose flour
- 2 teaspoons fresh thyme leaves (or 1 teaspoon dried)
- 1 teaspoon fresh rosemary, finely chopped (or 1/2 teaspoon dried)
- 1 bay leaf
- 1/2 teaspoon nutmeg, freshly grated if possible
- 1 1/2 teaspoons salt
- 1/2 teaspoon black pepper
- Pinch of cayenne pepper (optional)
For the Cheesy Topping:
- 2 cups shredded cheese blend (I recommend equal parts sharp cheddar, Gruyère, and Parmesan)
- 1/2 cup panko bread crumbs
- 2 tablespoons butter, melted
- 1 tablespoon fresh parsley, chopped
- 3 green onions, thinly sliced (for garnish)
Equipment You’ll Need
- 9×13 inch baking dish
- Heavy-bottomed saucepan
- Large mixing bowl
- Mandoline or sharp knife for slicing potatoes
- Aluminum foil
- Measuring cups and spoons
Step-by-Step Instructions
Preparing the Potatoes and Cream Sauce
- Preheat your oven to 350°F (175°C) and generously butter a 9×13 inch baking dish.
- Prepare the potatoes by washing them thoroughly, then slicing them to about 1/8-inch thickness. For the most consistent results, a mandoline is recommended, but a sharp knife works well too. Place the sliced potatoes in a large bowl of cold water to prevent browning while you prepare the other ingredients.
- Make the cream sauce by combining the heavy cream, milk, and bay leaf in a medium saucepan over medium-low heat. Warm this mixture until it just starts to steam, but don’t let it boil.
- Create a slurry in a small bowl by whisking together 2 tablespoons of the warm cream mixture with the flour until smooth, then whisk this back into the saucepan. This prevents lumps from forming in your sauce.
- Add the seasonings to the cream mixture: thyme, rosemary, nutmeg, salt, pepper, and cayenne (if using). Allow the mixture to simmer gently for about 5 minutes, stirring occasionally, until it thickens slightly. Remove from heat and discard the bay leaf.
Assembling the Casserole
- Drain the potatoes and pat them dry with paper towels. This removes excess starch and ensures your casserole isn’t watery.
- Layer the casserole by spreading about 1/3 of the potato slices in the bottom of the prepared baking dish, slightly overlapping them. Scatter 1/3 of the sliced onions and 1/3 of the minced garlic over the potatoes, then pour about 1/3 of the cream sauce over everything. Sprinkle with 1/2 cup of the shredded cheese blend.
- Repeat the layers twice more, finishing with the remaining cream sauce and reserving 1 cup of cheese for the final topping.
- Create the crunchy topping by mixing the reserved 1 cup of cheese with the panko breadcrumbs, melted butter, and chopped parsley in a small bowl. Set this aside for now.
Baking to Perfection
- Cover the dish tightly with aluminum foil and bake in the preheated oven for 45 minutes. This allows the potatoes to cook through in the steam created under the foil.
- Uncover and add topping – after 45 minutes, remove the foil, sprinkle the breadcrumb-cheese mixture evenly over the top, and return to the oven, uncovered.
- Bake until golden for an additional 25-30 minutes, or until the potatoes are completely tender when pierced with a fork and the top is bubbling and golden brown. If the top browns too quickly, cover loosely with foil.
- Rest before serving – remove from the oven and let the casserole rest for 15 minutes before serving. This allows the sauce to set slightly and makes serving neater.
- Garnish and serve – sprinkle with sliced green onions just before serving for a fresh pop of color and flavor.
Storage and Reheating Tips
- Refrigerate leftovers in an airtight container for up to 4 days.
- Freeze individual portions for quick future meals for up to 2 months.
- Reheat in a 325°F oven, covered with foil, for about 20 minutes, or until heated through. You can also microwave individual portions, but the texture won’t be quite as good.
Recipe Variations to Try
- Loaded Potato Casserole: Add cooked, crumbled bacon, extra cheese, and a dollop of sour cream on top after baking.
- Southwest Style: Mix in some diced green chiles, swap some of the cheese for pepper jack, and add 1/2 teaspoon of cumin to the cream sauce.
- Herb Garden Variation: Double up on the fresh herbs and add 2 tablespoons of pesto to the cream sauce for a vibrant, herbaceous twist.
- Ham and Potato Casserole: Add layers of thin-sliced ham between the potato layers for a heartier, main course version.
- Garlic Lover’s Delight: Roast a whole head of garlic and mix the soft cloves into the cream sauce for a mellower, sweeter garlic flavor throughout.
Serving Suggestions
This creamy potato casserole pairs beautifully with:
- Roasted meats like chicken, beef, or pork
- Grilled fish or seafood
- A simple green salad with vinaigrette
- Steamed or roasted green vegetables
- As part of a holiday feast alongside turkey or ham
