Looking for that “wow” moment to transform a banale appetizer into a shared memory? Forget soulfless mini-pastries: the sun tart is here.
The sun tart arrives on the table like a golden ray. It cracks under the fingers and reveals a melting heart that makes everyone say “more.” Simple to assemble and spectacular to serve, this dish invites a shared experience. The contrast is what makes it: crispy puff pastry meets a melting ham and cheese filling with a hint of mustard.
Ingredients for one sun tart (4 to 6 people)
- 2 discs of ready-to-use puff pastry (approx. 230 g each)
- 2 tbsp of whole-grain mustard
- 120 g of finely chopped white ham
- 120 g of shredded gruyère or emmental
- 1 egg yolk mixed with 1 tbsp of milk (for the wash)
- 1 tbsp of sesame or poppy seeds
- Optional: 1 grated garlic clove, 1 tsp of paprika, or fresh chives
Step-by-step recipe
1. Preparation: Preheat the oven to 400 °f. Unroll the first pastry disc onto a baking sheet. Spread the mustard, leaving a 1.5 cm border. Distribute the ham and cheese evenly. Add your optional spices or herbs. Place the second disc on top and seal the edges by pressing with your fingers.
2. Creating the “sun”: Place a small glass in the center to mark the middle. Using a sharp knife, cut the tart into 16 equal strips from the center circle to the edge. Take each strip and twist it twice, always in the same direction.
3. Baking: Brush the surface with the egg wash and sprinkle with seeds. Bake for 18 to 22 minutes until the pastry is puffed and golden. Let it rest for 5 to 10 minutes before serving so the filling can set.
Pro tips for a perfect result
- Do not overfill: Too much mustard will make the pastry soggy, and too much cheese will leak. Balance is key to keeping the crunch.
- Sharp tools: Use a very sharp knife for clean rays. Regular strips make twisting easier and prevent the dough from breaking.
- Make ahead: You can assemble the tart in advance and keep it in the fridge. Only apply the egg wash right before sliding it into the oven.
Variations and serving ideas
- Cheese lovers: Use 120 g of comté and 30 g of mozzarella for an extra-stretchy result.
- Bold version: Mix 100 g of ham with 30 g of crumbled blue cheese and a pinch of black pepper.
- Fresh touch: Combine the cheese with lemon zest and fresh chives.
To preserve the crunch, always reheat leftovers in the oven at 350 °f for 6 to 8 minutes. Avoid the microwave, as it will make the pastry soft and chewy. Serve it warm, let everyone pull off a “ray,” and enjoy the most convivial appetizer of the season.
