Ingredients
- 3 cup(s) (about 10 ounces) grated Gruyère cheese
- 8 ounce(s) cream cheese, softened
- 1 tablespoon(s) Dijon mustard
- 1 tablespoon(s) chopped fresh oregano
- 3/4 teaspoon(s) fresh ground pepper
- 2 tablespoon(s) unsalted butter
- 2 large (2 cups) sweet yellow onions, sliced 1/4 inch thick
- 2 tablespoon(s) fresh thyme
- 1 recipe Country Living's Quick Puff Pastry
- 1/2 cup(s) kalamata olives, sliced
Preparation
Step 1
Make the tarts: Heat oven to 400 degrees F. Mix Gruyère, cream cheese, mustard, oregano, and pepper in a small bowl and set aside. Melt butter in a large skillet, add onions, and cook, stirring occasionally, over medium-low heat until dark brown and caramelized -- about 1 hour. Stir in the thyme and set aside. With a sharp knife, cut the puff pastry dough into 8 equal-sized pieces. Roll each piece out to 8- by 6-inch rectangle. Spread about 1/4 cup of the cheese mixture on the dough, leaving a 1/2-inch border all the way around. Top with 1/4 cup of the caramelized onions and 1 tablespoon of the olives. If freezing, skip to Step 2 or bake tarts on parchment-lined baking pans for 10 minutes, reduce oven temperature to 375°F, and bake until puffed and golden -- about 12 more minutes.
Freeze the tarts: Place uncooked tarts on parchment-lined baking pans, cover with plastic wrap, and freeze until solid -- about 2 hours. Wrap each frozen tart securely in freezer paper or aluminum foil and stack them in an airtight container. Store frozen for up to 2 months. To serve, bake frozen tarts at 400°F for 12 minutes, reduce oven temperature to 375°F, and bake until puffed and golden -- about 15 more minutes.
