- 7 g Active dry yeast
- 150 ml Warm water
- 1 tsp Salt
- 2 tbsp Olive oil
- 2 medium Onions(thinly sliced)
- 200 g Gruyère cheese(grated)
- 100 g Emmental cheese(grated)

👨🍳 Instructions
- 1
In a small bowl, combine warm water and yeast. Let it sit for 5-10 minutes until foamy.
⏱️ 10 minutes - 2
In a large bowl, combine flour and salt. Add the yeast mixture and olive oil. Mix until a dough forms.
💡 Tip: Knead the dough on a lightly floured surface for about 5-7 minutes until smooth and elastic. - 3
Place the dough in a greased bowl, cover, and let it rise in a warm place for about 1 hour, or until doubled in size.
⏱️ 60 minutes - 4
While the dough is rising, sauté the diced bacon (if using) until crisp. Remove bacon and set aside, leaving the rendered fat in the pan. Sauté the sliced onions in the bacon fat (or a little olive oil if not using bacon) until softened and lightly golden.
⏱️ 15 minutes - 5
In a bowl, combine the grated Gruyère and Emmental cheeses, sautéed onions, heavy cream, black pepper, and nutmeg. Mix well.
💡 Tip: If not using bacon, you can add a pinch of smoked paprika for a smoky flavor. - 6
Preheat oven to 200°C (400°F). Punch down the risen dough and roll it out into a large rectangle (about 30x40 cm) on a floured surface or parchment paper.
⏱️ 5 minutes - 7
Spread the cheese mixture evenly over the dough, leaving a small border. Sprinkle the cooked bacon (if using) over the cheese mixture.
💡 Tip: You can also fold the edges of the dough inwards slightly to create a rustic crust. - 8
Bake for 25-30 minutes, or until the crust is golden brown and the cheese is bubbly and slightly browned.
⏱️ 30 minutes - 9
Let cool slightly before slicing and serving. This dish is delicious served warm.
