It’s almost fall, which means we’re coming into butternut squash season. Yay! I love butternut squash. It screams fall – with its orange-y color as well as its pumpkin-y taste. Mild, sweet and a bit creamy, I love cooking with it. Two of my favorite butternut squash recipes are my Roasted Chicken Sausage and Butternut Squash and this one – Butternut Squash Gratin.

Hunks of cooked squash are layered, in a shallow gratin or baking dish, with sharp and flavorful Gruyere cheese, toasted baguette slices and a leek-white wine mixture. It’s then topped off with Parmesan cheese . . .

. . . and baked until the top is browned and bubbly – a requisite for being a gratin. Oh, so cheesy, pretty and delicious! Add a tossed green salad and you have complete vegetarian meal.

  • Yield: 4 servings 1x
  • Category: Vegetarian main dish, gratin
Scale

Ingredients

  • 3 pounds butternut squash
  • 1 teaspoon extra virgin olive oil
  • 1/2 cup chopped leek
  • 1/2 cup dry white wine
  • 1/2 cup chicken broth
  • 1 can (12 ounce) evaporated regular or skim milk
  • 1/2 teaspoon sugar
  • 1 small French baguette (or half of a large)
  • 1 cup (4 ounces) shredded Gruyere cheese
  • 2 tablespoons grated Parmesan cheese, or more to taste

Instructions

  1. Preheat oven to 400 degrees. Butter a 6 to 8-cup shallow gratin or baking dish.
  2. Cut the squash in half, remove the seeds and place, cut side up, in a rimmed baking pan. Season with salt and pepper, cover with aluminum foil and bake until tender but not mushy, around 1 hour. Set aside and let cool enough to handle. Leave the oven on.
  3. While the squash is cooking, slice the baguette into 1/2-inch pieces and toast the slices until light brown. Set aside.
  4. Heat the olive oil in a medium saucepan over medium heat. Add the chopped leek and 2 teaspoons water; cover and cook over medium-low heat until the leek is soft, about 5 minutes. Stir in the wine. Increase the heat to medium-high and boil, uncovered, for 3 minutes. Remove from the heat and stir in the chicken broth, milk and sugar. Add salt and pepper to taste.
  5. Once the squash is cool enough to handle, reheat the leek mixture.
  6. Scoop the flesh from 1/2 of the squash into large pieces and place in the prepared baking dish, covering the bottom. Place approximately 1/2 of the baguette slices over the squash to cover, with space in between the slices. Cover with 1/2 of the leek mixture and 1/2 of the Gruyere cheese. Repeat layers. Sprinkle the top with the Parmesan cheese. Bake for 30 minutes, or until the top is brown and bubbly. Serve immediately.

Notes

Make ahead: Gratin can be assembled but not baked earlier in the day, covered and refrigerated. Bring to room temperature before cooking.
