Ingredients

• 500 grams potatoes
• 2 medium zucchini
• 2 medium carrots
• 1 large onion
• 2 large garlic cloves
• 2 tablespoons olive oil
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 500 milliliters milk
• 150 grams grated Gruyère cheese
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.25 teaspoon nutmeg
• 100 grams breadcrumbs
• 2 tablespoons chopped parsley

Directions

Step 1

Preheat your oven to 200°C (400°F). Lightly grease a large baking dish with some of the olive oil.

Step 2

Peel and thinly slice the potatoes. Slice the zucchini and carrots into similar-sized rounds to ensure even cooking.

Step 3

Peel and finely chop the onion and garlic.

Step 4

Heat the olive oil in a large frying pan over medium heat. Add the onion and garlic and sauté until soft and translucent, about 5 minutes.

Step 5

In a separate saucepan, melt the butter over medium heat. Stir in the flour, cooking for about 1 minute until the mixture forms a bubbling paste.

Step 6

Gradually add the milk, whisking continuously to avoid lumps, and cook until the sauce thickens slightly.

Step 7

Stir in 100 grams of the grated Gruyère cheese, salt, black pepper, and nutmeg. Continue to stir until the cheese is melted and the sauce is smooth.

Step 8

Layer half of the sliced potatoes in the bottom of the prepared baking dish. Top with half the sautéed onions and garlic, followed by half the zucchini and carrots.

Step 9

Pour half of the cheese sauce over the layered vegetables, spreading it evenly with a spatula.

Step 10

Repeat the layers with the remaining vegetables and cheese sauce.

Step 11

Mix the remaining Gruyère cheese with the breadcrumbs and chopped parsley, and sprinkle this mixture evenly over the top of the vegetables.

Step 12

Cover the baking dish loosely with aluminum foil and bake for 30 minutes.

Step 13

Remove the foil and continue to bake for an additional 20 minutes or until the top is golden and crispy and the vegetables are tender.

Step 14

Let the gratin rest for a few minutes before serving. Enjoy your delicious vegetable gratin!
