Ingredients

Scale

For the Gratin:

  • 6 tablespoons butter
  • 1 pound yellow onions, cut in half and sliced (about 3 large)
  • 2 pounds zucchini and/or yellow squash, sliced 1/4-inch thick (about 4 medium zucchini)
  • 2 teaspoons kosher salt (use 1/2 teaspoon if using table salt)
  • 1/2 teaspoon freshly ground black pepper
  • 1/4 teaspoon ground nutmeg
  • 2 cloves garlic, finely minced or pressed
  • 2 tablespoons all-purpose flour
  • 1 cup warm milk
  • 3/4 cup Italian-style bread crumbs
  • 3/4 cup grated Gruyere

Instructions

  1. Preheat the oven: Preheat the oven to 400 degrees F.
  2. Caramelize the onions: Melt butter in a large sauté pan, cook onions over low heat for about 20 minutes until tender but not browned.
  3. Cook the zucchini: Add zucchini to the pan, cover, and cook for 8-10 minutes until tender. Add salt, pepper, nutmeg, and garlic, then cook uncovered for 5 more minutes.
  4. Make the sauce: Whisk flour into warm milk, add to the pan, and cook until thickened.
  5. Assemble the gratin: Pour the zucchini mixture into a baking dish. Combine bread crumbs and Gruyere, sprinkle on top, drizzle with olive oil, and bake for 20 minutes until golden brown.
  6. Serve: Allow the gratin to cool slightly before serving.
