🧂 Ingredients for creamy egg gratin recipe

For the gratin:

500 grams of potatoes

100 grams of butter

125 ml of cream

2 leeks

50 grams of flour

100 ml of water

500 ml of milk

Salt and pepper to taste

100 grams of cheese

4 eggs

1 teaspoon of vegetable oil

👩‍🍳 How to Make This Creamy Egg Gratin Recipe

1. Prepare the Potatoes

Start by peeling and washing your potatoes, then cut them into medium-sized cubes. Cook them in a pot of salted water for about 20 minutes until tender. Drain well, then mash them with half of the butter and the cream until smooth and fluffy.

This creamy base will become the heart of your gratin — light, buttery, and rich in texture.

2. Cook the Leeks

Clean, wash, and dry the leeks thoroughly. Slice only the white parts thinly. Add them to a saucepan with 100 ml of water and cook over medium heat for about 10 minutes, until they’re tender and fragrant. Set aside to cool slightly.

Leeks add a delicate, almost sweet flavor that pairs beautifully with the potatoes and eggs.

3. Boil the Eggs

In another pan, cook the eggs in salted water for 10 minutes. Once done, rinse them under cold water and peel them. Cut them in half and set aside.

4. Make the Béchamel Sauce

In a small saucepan, melt the remaining butter over low heat. Add the flour, stirring constantly until a smooth paste forms. Slowly pour in the milk, whisking continuously to avoid lumps.

Cook for about 5 minutes until the sauce thickens, then add grated cheese, salt, and pepper. Stir well until creamy and glossy.

5. Assemble the Gratin

Preheat your oven to 180°C (350°F).
Grease a baking dish with a drizzle of vegetable oil, then add the mashed potatoes and leeks, mixing them together gently. Arrange the egg halves on top, pressing lightly into the mash.

Pour the béchamel sauce evenly over the dish, ensuring it covers the surface completely.

6. Bake to Perfection

Bake your gratin for 15 minutes, or until the top is bubbling and golden brown.
Once baked, sprinkle with a touch of fresh parsley for color and freshness.

🧀 Tips for the Perfect Egg Gratin

Use starchy potatoes like Russet or Yukon Gold — they make your mash creamier and smoother.

Don’t skip the resting time: letting the béchamel cool slightly before pouring helps it set beautifully in the oven.

Add a crunch: top your gratin with a few breadcrumbs before baking for a golden, crispy layer.

Experiment with cheese: Gruyère, cheddar, or mozzarella can give your dish a unique flavor twist.

🌿 Variations

Vegetarian twist: Replace the eggs with grilled vegetables like zucchini or spinach.

Smoky flavor: Add a sprinkle of smoked paprika or crispy bacon bits on top before baking.

Extra creamy: Stir in a spoonful of mascarpone or cream cheese to your mashed potatoes for a silkier texture.
