Ingredients
portions
- 400 gram onions (approx. 4 medium onions)
- 50 gram butter
- 1 roll puff pastry (fresh, from the refrigerated section)
- 3 eggs (medium)
- 125 ml heavy cream
- ½ tbsp Dijon mustard
- 50 gram Comté cheese (grated)
- 1 tsp thyme (dried or fresh)
- olive oil, salt, and pepper
Equipment
- Frying pan
- Quiche pan
- Ceramic beans
- Parchment paper
INSTRUCTIONS (how to make this recipe):
- Peel the onions and slice them (using a mandoline) into very thin rings.
- Take a frying pan and add a splash of olive oil along with the butter; add the onions once the butter has melted. Sautée the onions briefly, then reduce the heat to low until the onions are fully caramelized, which takes about 30–45 minutes.
- Let them cool slightly while you continue with the quiche. In the meantime, preheat the oven to 180 degrees Celsius / 356 Fahrenheit with top and bottom heat.
- Grease the quiche pan with oil or butter and spread the puff pastry over it. Prick the bottom with a fork.
- Place a sheet of parchment paper on top and fill it with baking beans. Now we’ll pre-bake the quiche for 15 minutes to create a nice flaky crust. After baking, remove the parchment paper and baking beans from the pan.
- Meanwhile, place the eggs, heavy cream, mustard, and grated cheese in a large bowl and whisk until combined. Season with salt and pepper.
- First, spread the caramelized onions over the quiche pan, pour the mixture over them, and finally sprinkle with thyme. Bake the quiche for 30–45 minutes until done. Serve with a nice fresh salad and enjoy!
