A Sun-Soaked Parisian Rebel: Heirloom Tomato & Melted Shallot Galette
Growing up in Paris, a Tarte à la Moutarde was my absolute favorite bistro staple. But honestly? The formal fluted tart pans always felt too fussy once I moved to California. This freeform, sun-soaked galette is my West Coast rebellion! I remember the exact moment the idea struck me—I was at the Santa Monica farmers market, chatting with my favorite grower, Luis, who handed me a bruising, impossibly heavy Brandywine tomato. It begged to be the star. For this recipe, we are slathering a ruthlessly buttery, flaky crust with sharp Dijon and piling it high with jammy, slow-melted shallots. The heirloom tomatoes concentrate beautifully in the oven, creating a sweet and savory bomb. It is exactly what I want to slice into on a blanket at a summer picnic, clutching a chilled glass of skin-contact Pinot Gris. Do not be precious about it! Swap the Dijon for whole grain if you want extra texture, or throw some fresh thyme over the tomatoes before baking. Just promise me you will never apologize for using real, good butter in your dough. Grab a glass of natural wine and let us get baking!

Timeline
Ingredients
- 1 1/4 cups All-purpose flour(Plus more for dusting)
- 1/2 cup Unsalted butter(Cold, cubed (use the good European stuff!))
- 4 tbsp Ice water
- 1.5 lbs Heirloom tomatoes(Sliced 1/4-inch thick, a mix of colors)
- 1 tsp Flaky sea salt(Plus more for finishing)
- 4 large Shallots(Thinly sliced)
- 2 tbsp Olive oil
- 2 tbsp Dijon mustard(Smooth, pungent French Dijon)
- 1 cup Comté cheese(Grated (Gruyère works too))
- 1 large Egg(Beaten, for egg wash)
- 1 tbsp Fresh thyme(Leaves picked)
- 1 Meyer lemon(Zested)
Instructions
- 1
Slice 1.5 lbs heirloom tomatoes and lay them out on a layer of paper towels. Sprinkle evenly with 1 tsp flaky sea salt. Let them hang out and release their excess moisture. We don't want a soggy galette bottom!
10 min
Tip: Don't skip this step. Tomatoes hold a lot of water, and salting them concentrates their flavor beautifully.
- 2
In a bowl, toss 1 1/4 cups all-purpose flour with 1/2 cup unsalted butter. Using your fingers, snap the butter into the flour until the mixture resembles coarse sand with some pea-sized pieces. Drizzle in 4 tbsp ice water and gently bring the dough together into a shaggy ball.
10 min
Tip: Work quickly so the butter doesn't melt from the heat of your hands. Flaky crust depends on cold butter.
- 3
Flatten the dough into a disc, wrap it tightly, and let it rest in the refrigerator.
30 min
Tip: Resting hydrates the flour and relaxes the gluten, ensuring a tender bite.
- 4
While the dough chills, heat 2 tbsp olive oil in a skillet over medium heat. Add 4 large shallots and cook them down gently until they are deeply caramelized, sticky, and melted. Set aside to cool slightly.
15 min
Tip: Take your time with the shallots. They are the sweet, jammy backbone of this dish.
- 5
Preheat your oven to 400°F (200°C) and place a baking sheet on the middle rack to get hot.
15 min
Tip: Baking the galette on a preheated baking sheet guarantees a crisp, golden bottom crust.
- 6
Roll the chilled dough out onto a large sheet of parchment paper until you have a rough 12-inch circle. Don't worry about jagged edges; rusticity is a compliment in my kitchen.
5 min
Tip: If the dough cracks a little at the edges, just pinch it back together.
- 7
Spread 2 tbsp Dijon mustard evenly over the dough, leaving a generous 2-inch border. Scatter the melted shallots and 1 cup Comté cheese over the mustard. Pat the salted tomatoes completely dry with paper towels, then arrange them on top in a slightly overlapping, rustic circle. Fold the edges of the dough up and over the tomatoes, pleating as you go. Brush the exposed crust with 1 large egg.
10 min
Tip: The layer of Dijon and cheese acts as a delicious waterproofing layer for the crust against the juicy tomatoes.
- 8
Carefully slide the parchment paper with the assembled galette onto the preheated baking sheet in the oven. Bake until the crust is deeply golden brown and the tomatoes are blistered and jammy.
40 min
Tip: Check the bottom of the crust towards the end of baking to ensure it's fully cooked and rigid.
- 9
Remove from the oven and let it cool slightly on a wire rack. Before serving, shower the galette with 1 tbsp fresh thyme and the zest of 1 Meyer lemon.
15 min
Tip: Letting it cool for at least 15 minutes allows the juices to set so it slices cleanly.
Chef's Notes
This galette is a love letter to the Parisian summer picnic, but dressed for the California sun. The sharp bite of Dijon and the nutty richness of Comté play so beautifully with the sweet, acidic heirloom tomatoes. A little Meyer lemon zest at the end brings an unexpected, floral brightness that cuts through the butter. Pair this with a chilled, slightly funky natural orange wine and you have an absolute feast.

French soul, California sun
I grew up in a small village outside Lyon, where my grandmother taught me that the best meals come from respecting your ingredients. After training at Le Cordon Bleu and spending years in Parisian kitchens, I moved to San Francisco and fell in love with California's farmers markets and wine country. Now I cook the food I wish my grandmother could taste—French technique with California abundance, where a perfect roast chicken might come with Meyer lemon and wild fennel instead of tarragon.
