Ingredients

1 tablespoon olive oil
1 tablespoon butter
2 tablespoons breadcrumbs
1 teaspoon thyme
Salt

Ingredient Selection Tips

Zucchini

Choose young, firm, and shiny zucchinis. Their thinner skin is more tender, and the seeds are less developed.

Comté Cheese

Opt for well-aged Comté for a stronger flavor. The more it’s aged, the more character it will have.

Cream

Using full-fat cream provides a richer texture and holds up better during cooking.

Herbs

Fresh thyme is best, but dried thyme works well too.

Equipment Needed

Gratin dish
Mandoline or sharp knife
Grater
Cutting board
Frying pan
Spatula

Preparation Steps

Preheat the Oven

Preheat your oven to 190°C (375°F).

Prepare the Zucchini

Wash and dry the zucchinis thoroughly.
Trim the ends and slice them into rounds about 5 mm thick.
Place in a colander, sprinkle with a little salt, and let drain for about 15 minutes.

Grate the Cheese and Prepare the Garlic

Grate the Comté if necessary.
Peel and finely chop the garlic cloves.
Lightly butter the gratin dish.

Step-by-Step Cooking

Step 1: Drain the Zucchini

Gently pat the zucchini slices with paper towels to remove excess moisture for a creamier gratin.

Step 2: Sauté the Vegetables

In a large skillet, heat the olive oil, then add the garlic followed by the zucchini. Sauté for about 6 to 8 minutes, stirring gently to keep them slightly firm.

Step 3: Season

Add thyme and generously pepper. Adjust salt as needed, then mix gently.

Step 4: Layer the Gratin

Start with a layer of zucchini in the dish.
Add a handful of Comté cheese.
Top with another layer of zucchini.
Slowly pour the cream over everything.
Sprinkle the remaining Comté cheese and breadcrumbs on top, finishing with small dots of butter.

Step 5: Bake

Bake for about 30 minutes until golden and crispy. If needed, finish under the broiler for an additional 2 to 3 minutes.

Step 6: Rest

Let the gratin rest for 5 to 10 minutes after removing it from the oven to enhance flavors and ease serving.

Signs of a Successful Gratin

A successful gratin will have a golden crust and a crispy surface. The zucchinis should be tender yet hold their shape, and the cream should thicken and coat the vegetables evenly. The delightful aroma of melted Comté, garlic, and thyme should be evident.

Chef’s Tips for Extra Flavor

Let the zucchini drain: This step significantly improves texture.
Mix different ages of Comté: Combining young and aged Comté adds complexity.
Add a pinch of nutmeg: Just a hint elevates the cream.
Color the zucchini lightly before layering: Quick sautéing enhances their natural sweetness.
Finish under the broiler: A few minutes will provide an even crispier topping.

Common Mistakes to Avoid

Avoid large zucchinis: They contain more seeds and moisture.
Don’t skip drying them: This is the main reason for a watery gratin.
Do not overcook vegetables before baking: They’ll continue to cook in the oven.
Use an appropriate amount of cream: You want to coat the vegetables, not drown them.
Limit excessive salt: Comté already adds a lovely salty flavor.

Delicious Variants

Bacon Version: Add 150 g of crispy cooked bacon.
Complete Vegetarian Version: Incorporate thinly sliced pre-cooked potatoes.
Mushroom Version: Sauté button mushrooms with zucchini for added flavor.
Tomato Version: Layer in sliced tomatoes between the zucchini.
Nut Version: Add chopped walnuts for added crunch before baking.

Serving Suggestions

This gratin pairs wonderfully with:

Grilled chicken breast
Roast pork
Salmon fillet
Veal chops
Roasted white meat
Vinaigrette-dressed green salad
Heirloom tomato salad
Crunchy country-style baguette

For a complete meal, serve it with a composed salad.

Presentation Tips

Serve directly from the gratin dish to retain warmth. Garnish with freshly chopped parsley at serving. A dash of black pepper and a few cheese shavings will finish the dish beautifully. Opt for a subtle ceramic dish to highlight the golden crust.

Storage Guidelines

Comté gratin zucchini can be stored in an airtight container in the fridge for up to 3 days.

Freezing

This gratin freezes well. Allow it to cool completely before placing it in an airtight container. It can be kept for up to 2 months.

Reheating

Reheat in the oven at 170°C (340°F) for about 15 minutes to restore texture. You can also use a microwave, but it may soften the crust.

Make Ahead

The gratin can be fully assembled a few hours before baking. Store it in the fridge and bake just before serving. You can also cook the zucchini the day before to save time.
