Difficulty Level
Medium – approachable for home cooks ready to impress with technique and flavor layering
Ingredients
- 2 cups peeled and thinly sliced butternut squash
- 2 cups peeled and thinly sliced sweet potatoes
- 1 large parsnip, peeled and thinly sliced
- 1 medium onion, finely chopped
- 3 cloves garlic, minced
- 2 tablespoons unsalted butter
- 2 cups heavy cream
- 1 cup whole milk
- 1 cup grated Gruyère cheese (plus extra for topping)
- ½ cup grated Parmesan cheese
- 1 teaspoon fresh thyme leaves
- Salt and freshly ground black pepper, to taste
- ¼ teaspoon freshly grated nutmeg
- 1 tablespoon all-purpose flour
- Fresh parsley, finely chopped, for garnish (optional)
Instructions
- Preheat your oven to 375°F (190°C) and butter a 9×13 inch baking dish to ensure your gratin won’t stick.
- Prepare the béchamel sauce: In a medium saucepan, melt 2 tablespoons unsalted butter over medium heat. Add the chopped onion and minced garlic, and sauté until fragrant and translucent, about 5 minutes.
- Sprinkle 1 tablespoon all-purpose flour over the sautéed aromatics and whisk continuously for 2 minutes to cook out the raw flour taste.
- Gradually pour in 2 cups heavy cream and 1 cup whole milk while whisking to avoid lumps. Bring the mixture to a gentle simmer, stirring until it thickens to coat the back of a spoon.
- Remove from heat and stir in 1 cup Gruyère cheese, ½ cup Parmesan cheese, fresh thyme leaves, nutmeg, and season generously with salt and freshly ground black pepper. Set the sauce aside.
- Layer the vegetables: Arrange alternating layers of thinly sliced butternut squash, sweet potatoes, and parsnip in the prepared baking dish, seasoning lightly with salt and pepper between layers.
- Pour the béchamel and cheese sauce evenly over the layered vegetables, pressing gently to submerge the slices for ultimate creaminess.
- Sprinkle a generous handful of Gruyère cheese on top for that iconic golden crust.
- Bake uncovered for 45-50 minutes, or until the vegetables are tender when pierced with a fork and the top is bubbling and beautifully browned.
- Allow the gratin to rest for 10 minutes before serving, letting the layers settle and the flavors intensify.
- Garnish with a sprinkle of fresh parsley for a burst of color and freshness just before serving.
Tips for Success
- For perfectly tender slices that cook evenly, use a mandoline to achieve uniform thickness (about 1/8 inch).
- If you’d like a lighter gratin, substitute half the cream for whole milk or use crème fraîche for an extra tangy depth.
- Adding a few sage leaves or a pinch of smoked paprika to the béchamel can elevate the dish with unexpected warmth.
- This gratin can be assembled a day ahead-cover it tightly and refrigerate. Bring it to room temperature before baking for best results.
- Want a crispy finish? Place the gratin under the broiler for 2-3 minutes at the end, watching closely to avoid burning.
Serving Suggestions
This fall vegetable gratin shines as a star side or a satisfying vegetarian main. Pair it with a crisp, acidic salad-think arugula tossed with lemon vinaigrette and toasted walnuts-to cut through the richness. For a heartier feast, serve alongside roasted pork tenderloin or herb-roasted chicken. Garnish each serving with fresh thyme sprigs or finely chopped parsley to enhance the visual appeal and deliver a fresh, herbaceous contrast.
For a cozy dinner, accompany with a glass of dry white wine like a Chardonnay or a light Pinot Noir to complement the creamy texture without overpowering the nuanced flavors.
