Ingredients Quantity
Zucchini 2 medium-sized
Yellow squash 2 medium-sized
Olive oil 2 tablespoons
Garlic (minced) 2 cloves
All-purpose flour 2 tablespoons
Milk 1 cup
Parmesan cheese (grated) 1/2 cup
Gruyere cheese (grated) 1/2 cup
Salt and pepper To taste
Fresh thyme (optional) For garnish


Now that we have all our ingredients ready, let’s get started on making zucchini gratin with yellow squash:

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) and grease a baking dish with olive oil.
  2. Prepare the Vegetables: Wash the zucchini and yellow squash, then trim off the ends. Using a sharp knife or mandoline slicer, thinly slice the zucchini and yellow squash into rounds.
  3. Make the Béchamel Sauce: In a saucepan, heat olive oil over medium heat. Add minced garlic and sauté until fragrant. Stir in the all-purpose flour to create a roux, then gradually whisk in the milk until smooth and thickened. Remove from heat and stir in half of the grated Parmesan and Gruyere cheese. Season with salt and pepper to taste.
  4. Assemble the Gratin: Arrange a layer of sliced zucchini and yellow squash in the greased baking dish, overlapping slightly. Pour half of the béchamel sauce over the vegetables, then sprinkle with some of the remaining grated cheese. Repeat with another layer of vegetables, béchamel sauce, and cheese.
  5. Bake the Gratin: Cover the baking dish with aluminum foil and bake in the preheated oven for 25-30 minutes, or until the vegetables are tender and the cheese is melted and bubbly. Remove the foil and broil for an additional 5 minutes to brown the cheese on top.
  6. Serve and Enjoy: Garnish the zucchini gratin with yellow squash with fresh thyme, if desired. Serve hot as a side dish or enjoy it on its own as a satisfying meal.

Tips for Success

  • Slice the Vegetables Thinly: To ensure even cooking, slice the zucchini and yellow squash into thin rounds, about 1/8 inch thick.
  • Use High-Quality Cheese: The flavor of the gratin largely depends on the quality of the cheese used. Opt for freshly grated Parmesan and Gruyere cheese for the best results.
