Ingredients
Scale
- 3 pounds Yukon Gold potatoes, peeled and thinly sliced
- 1 cup Boursin cheese (garlic and fine herbs flavor recommended)
- 2 cups whole milk
- 1 cup heavy cream
- 2 tablespoons unsalted butter
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme leaves
- 1 teaspoon salt
- ½ teaspoon freshly ground black pepper
- ½ cup grated Parmesan cheese (optional, for a golden crust)
- Fresh parsley for garnish (optional)
Substitutions: If you don’t have Boursin, a mixture of cream cheese with fresh garlic and herbs can be a good stand-in. For dairy, you can swap whole milk for a lighter milk, but keep the cream for richness.
Instructions
- Preheat your oven to 375°F (190°C). Lightly butter a 9×13-inch baking dish to prevent sticking.
- Peel and thinly slice the Yukon Gold potatoes. I find using a mandoline slicer helps keep the slices even—Mama Lou always stressed the importance of uniformity so the potatoes cook beautifully and evenly.
- In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant, but not browned. This little step releases the garlic’s sweetness without overpowering the dish.
- Pour in the milk and cream, then whisk in the Boursin cheese until melted and smooth. Stir in the thyme, salt, and pepper. Let this mixture warm gently—about 5 minutes—so the flavors marry together.
- Arrange a layer of potato slices at the bottom of your baking dish. Pour a ladle of the creamy Boursin sauce over the potatoes, ensuring they are well-coated. Repeat layering potatoes and sauce until all are used, finishing with a layer of sauce on top.
- If you’re using Parmesan, sprinkle it evenly over the top layer. This adds a lovely golden crust that my sister Ouma always raved about.
- Cover the dish tightly with aluminum foil and bake for 45 minutes. Then, remove the foil and bake for an additional 20-25 minutes, or until the potatoes are tender and the top is golden and bubbly.
- Let the scalloped potatoes rest for 10 minutes before serving. This helps the sauce thicken slightly and makes serving easier—trust me, Mama Lou insisted on this step every time.
