Ingredients

For the Pie Crust:

• 1 1/4 cups all-purpose flour
• 8 tablespoons (1 stick) unsalted butter, cubed and frozen
• 1/2 teaspoon salt
• 1 teaspoon sugar
• 5-6 tablespoons nonfat milk, very cold

For the Filling:

• 1/2 pound beefsteak tomatoes, sliced 1/4 inch thick
• 3 tablespoons olive oil
• 1 small onion, peeled and sliced into thin slices
• 1/2 cup heavy cream
• 2 teaspoons fresh thyme leaves
• 2 cloves garlic, minced
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• 1 cup grated cheese (Gruyère and Gouda)

Instructions

Make the Pie Crust:

1. Combine Dry Ingredients: In a food processor, combine the flour, salt, and sugar. Pulse until the mixture resembles coarse crumbs.
2. Add Butter: Add the cubed, frozen butter and pulse until the mixture resembles pea-sized pieces.
3. Add Milk: Slowly add the cold milk, one tablespoon at a time, pulsing until the mixture begins to form a rustic ball.
4. Shape Dough: On a lightly floured surface, shape the dough into a 5-inch disk. Wrap it in plastic wrap and refrigerate for at least one hour.
5. Roll Dough: Preheat your oven to 400°F (200°C). Allow the dough to sit out for about 15 minutes until pliable. Roll it into a large circle, turning it a quarter turn with each roll.
6. Transfer to Pan: Carefully transfer the dough into a 9-inch tart pan with a removable bottom. Press it tightly into the sides of the pan.
7. Blind Bake: Cover the dough with foil and fill it with pie weights or uncooked beans. Bake for 15-20 minutes, or until the edges are lightly golden. Remove the foil and bake for an additional 5-10 minutes. Let it cool on a rack.

Make the Filling:

1. Caramelize Onions: In a sauté pan, heat 2 tablespoons of olive oil over medium-low heat. Add the sliced onions and cook, stirring every few minutes, until translucent. Reduce the heat and continue cooking for 20-25 minutes until the onions are caramelized. Season with salt and pepper.
2. Sauté Garlic and Thyme: In a separate small sauté pan, add the remaining olive oil. Cook the minced garlic and thyme for about 30 seconds until fragrant. Pour in the heavy cream and increase the heat until the mixture is reduced by half. Stir in 3/4 cup of the grated cheese until melted and combined.
3. Assemble and Bake: Pour the reduced cream mixture into the prepared pie shell. Layer the caramelized onions and sliced tomatoes on top, then sprinkle with the remaining cheese. Bake until the tart is heated through and the cheese is melted, about 10-15 minutes. For a finishing touch, place the tart under the broiler for 5 minutes until golden and bubbly.
4. Garnish and Serve: Garnish with fresh basil before slicing and serving.
