Prep Time 20 minutes

Total Time 1 hour
Servings: 4

Cuisine: French
Calories: 250

Ingredients
  

  • 3 medium zucchini preferably young and firm
  • 1 cup grated cheese Gruyère or a similar melting cheese
  • 3 cloves garlic minced finely
  • 2 tablespoons unsalted butter melted
  • 1 cup heavy cream or full-fat milk for a lighter option
  • 1 teaspoon fresh thyme chopped, optional
  • to taste salt and pepper

Equipment

  • mandoline slicer
  • Baking dish
  • Mixing bowl
  • Wooden spoon
  • Oven

Method
 

  1. Preheat your oven to 375°F (190°C). Thinly slice the zucchini using a mandoline or sharp knife, aiming for uniform, delicate rounds.
  2. In a mixing bowl, combine melted butter, minced garlic, heavy cream, chopped thyme, salt, and pepper. Whisk until the mixture is smooth and fragrant.
  3. Grease your baking dish with a little butter or non-stick spray. Spread a thin layer of the cream mixture on the bottom to prevent sticking.
  4. Layer the sliced zucchini in overlapping circles or rows, slightly overlapping for even layering. Pour a spoonful of the cream mixture over each layer, and sprinkle with grated cheese.
  5. Repeat the layering process — zucchini, cream, cheese — until the dish is filled, finishing with a layer of cheese on top.
  6. Place the gratin in the oven and bake for about 40 minutes, until bubbling around the edges and a golden brown crust forms on top.
  7. Remove from the oven and rest for 5 minutes. The dish should have a crispy crust and tender, creamy zucchini inside. Garnish with fresh herbs if desired, and serve warm.

Notes

Use a mandoline for the thinnest, most uniform slices. Adjust baking time as needed for thicker or thinner zucchini slices.

Having this gratin on the table is like opening a chapter in a history book filled with fragrant, buttery stories. It reminds us that some recipes are worth the patience, that good food isn’t rushed but savored in the quiet moments. There’s a kind of peace found in letting the oven do its work, transforming simple ingredients into something memorable.

When I close the oven door and see that golden top bubbling, I feel a sense of quiet achievement. It’s a dish that’s rooted in tradition but feels just right for today’s table—beautiful, comforting, and real. A humble reminder that sometimes, the simplest ingredients bring the most warmth.
