Ingredients
Pastry Base
- 1 sheet ready-made puff pastry (all butter)
- 1/4 cup Dijon mustard
- 1 egg, lightly beaten (for egg wash)
Filling & Toppings
- 2 cups thinly sliced new potatoes (preferably sliced with a mandolin)
- 1 1/2 cups shredded Gruyere or similar melting cheese
- 2 tablespoons chopped fresh chives and dill
- 2 tablespoons poppy seeds
- Olive oil for drizzling
Instructions
- Preheat and Prepare Pastry: Preheat the oven to 400ºF (200ºC). Lay out the puff pastry sheet on a baking tray lined with parchment paper. Using a mandolin or sharp knife, thinly slice the new potatoes.
- Spread Mustard: Evenly spread the Dijon mustard over the puff pastry, leaving a 1-inch border around the edges to create a crust.
- Add Cheese and Potatoes: Sprinkle a layer of shredded Gruyere cheese over the mustard-coated pastry. Arrange the thinly sliced potato slices evenly on top of the cheese, keeping the 1-inch border free.
- Drizzle Olive Oil and Fold Edges: Drizzle olive oil lightly over the potatoes to keep them moist and flavorful. Fold the edges of the puff pastry over to encase the potatoes slightly.
- Egg Wash and Toppings: Brush the exposed pastry edges with the beaten egg wash for a golden finish. Sprinkle poppy seeds evenly over the egg-washed pastry edges for added texture and flavor.
- Add Final Cheese and Herbs: Sprinkle the remaining shredded cheese over the potatoes and pastry edges. Follow by scattering the chopped chives and dill over the tart.
- Bake the Tart: Place the tart in the preheated oven and bake for about 25-30 minutes, or until the pastry is golden brown, puffed, and the potatoes are tender. Once out of the oven, optionally drizzle with extra olive oil and garnish with additional fresh herbs.
Notes
- Use all-butter puff pastry for a richer flavor and better flakiness.
- Thinly slicing potatoes ensures they cook evenly and quickly.
- Gruyere cheese can be substituted with other melting cheeses like Emmental or Comté.
- Let the tart cool slightly before slicing to help the layers set.
- This tart pairs wonderfully with a fresh green salad or light soup.
