🧂 Ingredients
- 1 sheet (approx. 250g) Puff pastry
- 150 ml Crème fraîche
- 200 g Mushrooms (e.g., cremini, shiitake), thinly sliced
- 100 g Gruyère cheese, grated
- 1/2 medium Onion, thinly sliced
- 1 clove Garlic, minced
- 1 tbsp Butter
- 1 tbsp Olive oil
- to taste Salt
- to taste Black pepper
- 1 tsp Fresh thyme leaves (optional)
👨🍳 Instructions
- 1
Preheat your oven to 220°C (425°F). If using puff pastry, lightly roll it out on a floured surface to about 3-4mm thickness. Place it on a baking sheet lined with parchment paper.
💡 Tip: Ensure the oven is fully preheated for a crispy crust. - 2
In a skillet, melt butter and olive oil over medium heat. Add the sliced onions and cook until softened and lightly golden, about 5-7 minutes.
💡 Tip: Low and slow cooking of onions brings out their sweetness. - 3
Add the minced garlic and sliced mushrooms to the skillet. Cook until the mushrooms have released their liquid and are tender and lightly browned, about 5-8 minutes. Season with salt, pepper, and fresh thyme if using.
💡 Tip: Don't overcrowd the pan when cooking mushrooms to ensure they brown rather than steam. - 4
Spread the crème fraîche evenly over the puff pastry, leaving a small border around the edges.
💡 Tip: Use the back of a spoon to spread the crème fraîche smoothly. - 5
Distribute the cooked mushroom and onion mixture evenly over the crème fraîche.
💡 Tip: Ensure an even distribution for balanced flavor in every bite. - 6
Sprinkle the grated Gruyère cheese over the mushrooms and onions.
💡 Tip: Grate the cheese fresh for the best melting consistency. - 7
Bake in the preheated oven for 12-15 minutes, or until the pastry is golden brown and puffed, and the cheese is melted and bubbly.
💡 Tip: Keep an eye on the tart to prevent the edges from burning. - 8
Let it cool slightly before slicing and serving. Enjoy hot.
💡 Tip: This tart is best served immediately.
