FrenchGardenHouse Spring Vegetable Tart with Gruyère

Spring is the time to bring fresh, vibrant flavors to the table, and this Spring Vegetable Tart with Gruyère captures that seasonality in a refined, effortless way. This tart stole my heart at a favorite French restaurant, and the chef shared the recipe so I could bring a taste of France home to my {and now your!} kitchen.{I changed it slightly to use easy ingredients available here.}

Crisp asparagus, tender baby spinach, and sweet leeks are bound together in a silky Gruyère custard and encased in a golden, buttery crust—simple ingredients elevated to something extraordinary.

A Celebration of Seasonal Flavors

This tart is light enough for brunch yet substantial enough for a lunch or dinner. The vegetables are cooked just until tender, preserving their color and brightness, while the Gruyère custard adds a gentle richness without overwhelming the delicate flavors.

A subtle sprinkle of Parmesan or fresh herbs at the finish enhances both texture and aroma. Its elegance lies in the balance: creamy, savory custard; crisp, flaky pastry; and bright, fresh spring vegetables. Every bite is a perfect combination of flavor, texture, and visual appeal.

{you can make your own crust, or if you are in a pinch for time, buy a pre-made crust...I love the Marie Calendar frozen crusts.}

Chef’s Tip

For a subtle finish, add more grated cheese on top and a light drizzle of extra-virgin olive oil and/or a few fresh herbs before serving. This tart is best enjoyed fresh but also keeps beautifully for a day or two, making it a perfect make-ahead dish for Easter or spring gatherings.

I hope you enjoy this easy tart, it's perfect for spring!
