Melted Leek & Comté Savory Clafoutis with Avocado-Herb Salad

I adore a classic quiche, but let's be honest—sometimes you don't have the patience for pastry on a Sunday morning. Enter the savory clafoutis. This crustless, gently baked custard is a bistro brunch dream. We slowly melt heaps of leeks until they're sweet and jammy, fold them into a lightened-up custard batter, and top it all with a bright, citrusy avocado salad that completely wakes up the dish. It’s breakfast in Paris, eaten under the California sun.

Ingredients

  • 2 tbsp unsalted butter(Divided: 1 tbsp softened for the dish, 1 tbsp for cooking leeks)
  • 2 tbsp extra-virgin olive oil(Divided: 1 tbsp for leeks, 1 tbsp for the salad topping)
  • 3 large leeks(White and light green parts only, halved and sliced thin)
  • 1 large shallot(Finely minced)
  • 1 tsp fresh thyme leaves
  • 1 tsp kosher salt(Divided use)
  • 4 large eggs(Room temperature)
  • 1.25 cups whole milk
  • 1/4 cup crème fraîche(Plus extra for serving, if desired)
  • 1/3 cup all-purpose flour
  • 1/4 tsp black pepper(Freshly ground)
  • 1/8 tsp freshly grated nutmeg
  • 1 tsp Meyer lemon zest
  • 1 tbsp Meyer lemon juice(From the zested lemon)
  • 1 cup Comté cheese(Freshly grated (Gruyère works beautifully too))
  • 1 ripe avocado(Pitted and cubed)
  • 1/2 cup mixed soft herbs(A mix of parsley, dill, and chives, roughly chopped)
  • 1 pinch flaky sea salt(For finishing)

Instructions

  1. 1

    Let’s get the oven going to 350°F (175°C). Generously grease a 9-inch ceramic pie or tart dish with 1 tbsp unsalted butter—don't be shy here, it helps the delicate custard release beautifully and gives the edges a golden crispness.

    5 min

    Tip: A ceramic dish holds the heat nicely for a gentle bake, but a cast-iron skillet works wonderfully too if you want more rustic, crispy edges.

  2. 2

    Clean and prep 3 large leeks. Halve them lengthwise, rinse out any hidden grit under cold water, and slice them thinly into half-moons.

    10 min

    Tip: Leeks are notoriously sandy. If they seem very dirty, soak the slices in a bowl of cold water, lift them out with your hands, and pat them dry.

  3. 3

    Place a medium skillet over medium-low heat. Add the remaining 1 tbsp unsalted butter and 1 tbsp extra-virgin olive oil. Toss in the prepared leeks along with 1 large shallot, 1 tsp fresh thyme leaves, and 1/2 tsp kosher salt. Let them sweat and melt down slowly, stirring occasionally, until they are incredibly soft, sweet, and jammy.

    15 min

    Tip: Don't rush the leeks! We want them tender and sweet, not browned. Turn down the heat if they start to take on too much color.

  4. 4

    While the leeks are performing their slow-melting magic, grab a large bowl. Whisk together 4 large eggs, 1.25 cups whole milk, 1/4 cup crème fraîche, 1/3 cup all-purpose flour, the remaining 1/2 tsp kosher salt, 1/4 tsp black pepper, and 1/8 tsp freshly grated nutmeg until the batter is completely smooth and frothy.

    5 min

    Tip: Sifting the flour in gently while you whisk helps prevent any lumps. The batter will seem quite thin—that's exactly what you want for a silky custard.

  5. 5

    Once the leeks are totally soft, remove them from the heat and stir in 1 tsp Meyer lemon zest. Spread this fragrant leek fondue evenly across the bottom of your prepared baking dish. Scatter 1 cup Comté cheese over the top of the leeks.

    2 min

    Tip: The lemon zest cuts the richness of the buttery leeks perfectly. Standard lemon works if Meyer isn't available, but Meyer adds that distinct, floral California sunshine.

  6. 6

    Gently pour the egg batter over the leeks and cheese. Carefully slide the dish into the middle rack of the oven and bake for 30 to 35 minutes.

    35 min

    Tip: You are looking for a gentle rise, golden puffed edges, and a center that is just set with a very slight wobble. It will continue to cook as it rests.

  7. 7

    When the clafoutis has about 5 minutes left in the oven, let's make a bright little salad. In a small bowl, gently toss 1 ripe avocado, 1/2 cup mixed soft herbs, 1 tbsp Meyer lemon juice, the remaining 1 tbsp extra-virgin olive oil, and 1 pinch flaky sea salt.

    5 min

    Tip: Toss this right at the end so the avocado stays pristine and the herbs don't wilt in the acid.

  8. 8

    Pull the clafoutis from the oven. Let it rest for 10 minutes—it will deflate slightly, which is completely normal. Spoon the fresh avocado-herb salad directly over the center of the warm custard. Slice into wedges and serve immediately.

    10 min

    Tip: Custards need a moment to collect themselves after leaving the oven. This resting time makes it much easier to slice neatly.

Chef's Notes

This is everything I want on a Sunday morning. The classic French technique of a clafoutis batter—usually reserved for cherries—is an absolute revelation when taken in a savory direction with Comté and slow-cooked alliums. To me, the avocado and herb salad on top isn't optional; that pop of California freshness completely transforms the dish. If you're hosting, pair this with a cloudy, lively Pét-Nat or a bright Crémant du Jura. It handles the butteriness of the leeks beautifully!
