How to Make Ultra-Creamy Scalloped Potatoes With Boursin

Step 1: Preheat and Prepare Your Dish

Start by preheating your oven to 400°F so it’s hot and ready. Grease a 9×13-inch baking dish thoroughly to prevent sticking and to help develop those golden edges that make scalloped potatoes irresistible.

Step 2: Make the Creamy Boursin Sauce

In a medium skillet over medium heat, melt the butter until bubbly. Whisk in the flour and continue whisking for about a minute to cook out the raw flour taste. Slowly add the milk and vegetable broth while whisking to avoid lumps, then incorporate the Garlic Boursin cheese until the sauce is smooth and velvety. Stir in the grated garlic, dried thyme, salt, and pepper. Let it cook, stirring often, for 2 to 3 minutes until the sauce thickens enough to coat the back of a spoon.

Step 3: Layer the Potatoes and Onions

Place half of the thinly sliced Yukon Gold potatoes in an even layer at the bottom of the baking dish. Scatter half of the thinly sliced Spanish onions over the potatoes. Pour half of the luscious Boursin sauce over the layers, then sprinkle 1/2 cup of the shredded Gruyere cheese. Repeat these layers with the remaining potatoes, onions, sauce, and cheese for maximum creaminess and flavor.

Step 4: Bake to Perfection

Cover the dish with foil and bake in the preheated oven for 30 minutes to let the potatoes start softening. Then remove the foil and continue baking uncovered for 35 to 40 minutes more, until the potatoes are tender through and the cheese topping is beautifully browned and bubbling.

Step 5: Rest and Garnish

Once out of the oven, allow your Ultra-Creamy Scalloped Potatoes With Boursin to rest at room temperature for about 20 minutes. This resting time helps set the layers for easier serving and enhances the overall flavor. Finish with a sprinkle of freshly chopped chives for a pop of color and freshness.

How to Serve Ultra-Creamy Scalloped Potatoes With Boursin

Garnishes

The simple touch of fresh chives not only adds visual appeal but also a subtle oniony bite that contrasts beautifully with the creamy potatoes. Feel free to experiment with finely chopped parsley or a light drizzle of good quality olive oil for an extra layer of flavor.

Side Dishes

These potatoes are a showstopper, but they pair wonderfully with protein-forward mains like roasted chicken, grilled steak, or even a holiday ham. For a vegetarian meal, serve alongside a crisp green salad or roasted vegetables to balance the richness.

Creative Ways to Present

For a special occasion, try making individual scalloped potato servings in ramekins for elegant plating. You could also top with toasted breadcrumbs for a crunchy contrast or mix in cooked bacon or caramelized onions between the layers for added savory surprises.

Make Ahead and Storage

Storing Leftovers

Your Ultra-Creamy Scalloped Potatoes With Boursin reheat beautifully, making them a fantastic make-ahead dish. Store leftovers in an airtight container in the refrigerator for up to 4 days without losing that creamy texture.

Freezing

This dish freezes well if you want to prep it far in advance. After baking and cooling completely, cover tightly with foil or plastic wrap and then place in a freezer-safe container. It will stay delicious for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

To bring back that golden bubbly finish after refrigeration or freezing, reheat uncovered at 350°F for about 25–30 minutes until warmed through. A quick sprinkle of extra cheese on top during reheating is a lovely way to refresh the gratin’s cheesy crust.

FAQs

Can I use a different type of cheese instead of Boursin?

While Boursin adds a unique garlicky creaminess, you can substitute with other soft herb cheeses or cream cheese mixed with garlic and herbs, though the flavor profile will change slightly.

Are Yukon Gold potatoes necessary, or can I use Russet potatoes?

Yukon Golds are preferred for their creamy texture and buttery flavor, but Russets can work too—they just may result in a slightly less creamy and more fluffy texture.

Can I prepare this dish entirely ahead of time and bake later?

Absolutely. Assemble the dish, cover, and refrigerate for up to 24 hours before baking. Just add a few extra minutes to the baking time if baking straight from the fridge.

Is it possible to make this recipe dairy-free?

This particular recipe relies heavily on dairy for its creamy texture and flavor, but you could experiment with plant-based milk, vegan butter, and dairy-free cheese alternatives—expect a different consistency and taste.

How thin should I slice the potatoes?

The potatoes should be sliced about 1/8 inch thick. Thin slices ensure even cooking and allow the sauce to seep into every layer for that signature creamy texture.
