Ingredients
Scale
Puff Pastry Base
- 1 package (17.3 ounces) puff pastry dough
Onion Mixture
- 2 Tablespoons olive oil
- 1 large yellow onion, thinly sliced
- 2 garlic cloves, minced
- Kosher salt, to taste
- Black pepper, to taste
- 3 Tablespoons chicken broth
- 2 teaspoons minced fresh thyme leaves
Toppings
- 1/2 cup freshly grated Parmesan cheese
- 6 ounces fresh Mozzarella cheese, cut into 1-inch cubes
- 2 Roma tomatoes, cut into 18 thin slices
- 3 Tablespoons julienned fresh basil leaves
- Olive oil, for brushing
Instructions
- Prepare Puff Pastry Circles: Defrost the puff pastry dough according to the package instructions. Preheat the oven to 425°F (220°C). Unfold one sheet of puff pastry on a lightly floured surface and roll it out into a 10×10 inch square. Using a 3-inch biscuit cutter, cut 9 circles from the sheet. Repeat with the second sheet to get 18 circles in total.
- Chill Dough Circles: Place the dough circles on two baking sheets lined with parchment paper. Refrigerate them until ready to use to keep the dough firm and prevent shrinking during baking.
- Sauté Onions and Garlic: Heat olive oil in a large skillet over medium-low heat. Add the thinly sliced onion and minced garlic. Cook for 10 to 12 minutes, stirring frequently until onions turn translucent and all moisture evaporates from the skillet.
- Add Seasonings and Broth: Sprinkle in 1/2 teaspoon kosher salt and 1/4 teaspoon black pepper. Add chicken broth and fresh thyme leaves. Stir well and continue cooking for another 10 minutes until onions are lightly browned. Remove from heat and set aside.
- Prepare the Tart Bases for Topping: Using a sharp paring knife, score a 1/4 inch border around the edge of each pastry circle. Prick the inside area with a fork to prevent puffing. Sprinkle about one teaspoon of Parmesan cheese inside the scored border on each circle.
- Assemble the Tarts: Spoon about one tablespoon of the onion mixture onto each pastry circle on top of the Parmesan. Center a tomato slice over the onion. Brush the tomato with olive oil and season lightly with salt and pepper. Place one cube of mozzarella cheese on top of each tomato slice.
- Bake the Tarts: Bake the tarts for 18 to 20 minutes in the preheated oven until the pastry is puffed and golden brown and the cheese starts to melt.
- Finish and Serve: Carefully remove the tarts from the oven. Garnish each with julienned fresh basil. Serve warm for the best flavor and texture.
Notes
- Make sure the puff pastry remains cold until baking to prevent shrinking and ensure flakiness.
- Use fresh mozzarella for the best melty texture; low-moisture mozzarella may yield drier results.
- You can substitute chicken broth with vegetable broth for a vegetarian option if desired.
- These tarts are best served fresh but can be reheated in a toaster oven for crispiness.
- For a slightly sweeter flavor, add a drizzle of balsamic glaze before serving.
