Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the crust:

• 1 1/4 cups all-purpose flour
• 1/2 tsp salt
• 1/2 cup unsalted butter, cold and cubed
• 3–4 tbsp ice water

For the filling:

• 2 large yellow onions, thinly sliced
• 1 tbsp olive oil
• 1 tbsp unsalted butter
• 1/2 tsp sugar
• 1/4 tsp salt
• 4 oz goat cheese, crumbled
• 1/4 cup heavy cream
• 1 egg
• Fresh thyme sprigs, for garnish

Directions

1. Make the crust: In a mixing bowl, combine flour and salt. Cut in the cold butter using a pastry cutter or fingers until the mixture resembles coarse crumbs. Gradually add ice water, mixing gently until the dough just holds together. Form into a disk, wrap in plastic, and refrigerate for 30 minutes.
2. Preheat oven to 375°F (190°C).
3. Roll out the chilled dough on a floured surface and cut into circles to fit 6 mini tart pans or a standard muffin tin. Press the dough into the pans and prick the bottoms with a fork. Bake for 10 minutes, then remove and set aside.
4. Caramelize the onions: In a skillet, heat olive oil and butter over medium heat. Add the sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring frequently, until the onions are golden brown and very soft. Remove from heat and let cool slightly.
5. In a small bowl, whisk together the cream and egg. Fold in half of the goat cheese.
6. Spoon a layer of caramelized onions into each tart shell. Pour in the cream mixture, then top with the remaining crumbled goat cheese.
7. Bake for 18–22 minutes, or until the filling is set and golden.
8. Garnish each tartlet with fresh thyme. Serve warm or at room temperature.
