Ingredients
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter
- 3 large yellow onions, thinly sliced
- 1/2 teaspoon salt
- 1/2 teaspoon sugar
- 1/4 teaspoon black pepper
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- 1 sheet puff pastry, thawed (store-bought or homemade)
- 6 oz goat cheese, softened
- 1 tablespoon heavy cream (optional, for creamier cheese spread)
- 1 egg, beaten (for egg wash)
- Fresh thyme or arugula, for garnish
Preparation
Step 1: Caramelize the Onions
Heat olive oil and butter in a large skillet over medium-low heat. Add the sliced onions and stir to coat. Cook slowly for 25–30 minutes, stirring occasionally, until onions are golden and soft. Add salt, sugar, black pepper, and thyme about 15 minutes into cooking. Once caramelized, remove from heat and set aside.
Step 2: Prepare the Puff Pastry
Preheat oven to 400°F (200°C). Roll out puff pastry on a lightly floured surface into a rectangle or square, depending on your tart shape preference. Cut into 4 equal squares for individual tarts or leave whole for one large tart. Transfer to a parchment-lined baking sheet.
Step 3: Score and Prick the Dough
Lightly score a 1/2-inch border around each square using a sharp knife (don’t cut all the way through). Prick the center area with a fork to prevent puffing during baking.
Step 4: Assemble the Tarts
Mix goat cheese with heavy cream if using, then spread a thin layer within the scored border. Top with a generous spoonful of caramelized onions, spreading evenly. Brush edges of the pastry with the beaten egg.
Step 5: Bake the Tarts
Bake in the preheated oven for 18–22 minutes, or until pastry is puffed and golden brown. Remove from oven and let cool slightly. Garnish with fresh thyme or a few arugula leaves if desired.
Variations
- Use blue cheese instead of goat cheese for a more pungent flavor
- Add roasted red peppers or sun-dried tomatoes on top for color
- Drizzle with balsamic glaze before serving for added depth
- Replace puff pastry with pie dough or phyllo for different textures
- Mix goat cheese with cream cheese for a milder taste
- Sprinkle crushed walnuts or pecans before baking for crunch
Cooking Notes
- Caramelizing onions takes time, don’t rush; low and slow brings out the best flavor
- Puff pastry should stay cold until baking to puff properly
- If using frozen puff pastry, thaw in the fridge for best texture
- Score and prick the pastry properly to create a border and prevent the middle from rising
- Use parchment to avoid sticking and for easier cleanup
- For mini party tarts, cut pastry into 9–12 smaller squares
Serving Suggestions
- Serve as an appetizer on a charcuterie-style board
- Pair with a crisp green salad for a light lunch
- Add to a brunch spread with quiche, fruit, and croissants
- Serve alongside soup like French onion or butternut squash
- Include in holiday or cocktail party menus for a savory bite
- Reheat in the oven at 350°F for 5 minutes to refresh before serving
Tips
- Make caramelized onions ahead and refrigerate for up to 5 days
- Let goat cheese sit at room temperature for easier spreading
- Garnish with microgreens or a balsamic drizzle for presentation
- If pastry puffs too much in the center, gently press it down post-baking
- Use a pizza cutter to evenly slice puff pastry before baking
- For a richer flavor, stir a splash of white wine into the onions during cooking
