Ingredients
- 1 sheet (12 oz), thawed puff pastry
- 2 medium (1 lb), peeled and diced into 1/4-inch cubes potatoes
- 1 large (1/2 lb), white and light green parts only, sliced into thin rings leeks
- 2 tbsp butter
- 1/2 cup heavy cream
- 1/4 cup, grated cheddar cheese
- 1/4 cup, grated Gruyere cheese
- 1/4 tsp salt
- 1/8 tsp black pepper
- 1 tbsp, chopped fresh thyme
Instructions
- Step 1: Preheat oven to 400°F (200°C). Roll thawed puff pastry sheet on a lightly floured surface and cut into 4-inch squares. Fold each square into a triangle, seal edges with a fork, and prick centers with a fork. Bake on parchment-lined baking sheet for 10 minutes until golden and puffed.
- Step 2: Melt 2 tbsp butter in a medium saucepan over medium heat. Add diced potatoes and sliced leeks, and cook for 5 minutes until potatoes are slightly softened. Stir in 1/2 cup heavy cream, 1/4 tsp salt, 1/8 tsp black pepper, and 1 tbsp chopped thyme. Simmer for 10 minutes until liquid reduces and potatoes are tender.
- Step 3: Remove baked tart shells from oven, fill each with potato-leek mixture, then sprinkle with 1/4 cup grated cheddar and 1/4 cup grated Gruyere. Return to oven for 8-10 minutes until cheese is melted and bubbly.
