How to Make French Onion Mushroom Tart
Creating this tart is straightforward and can be accomplished in just a few simple steps. Let’s break it down so you can serve up a beautiful dish in no time!
Ingredients:
- 1 sheet of puff pastry
- 2 medium onions, thinly sliced
- 8 ounces mushrooms, sliced
- 2 tablespoons olive oil
- 1 teaspoon thyme
- 1 cup grated Gruyère cheese
- Salt and pepper to taste
- 1 egg (for egg wash)
Directions:
Step 1: Preheat the Oven
Preheat the oven to 400°F (200°C).
Step 2: Caramelizing the Onions
In a skillet, heat the olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until they become golden brown and caramelized, about 15-20 minutes. The sweet aroma will fill your kitchen!
Step 3: Sautéing the Mushrooms
Add the sliced mushrooms and thyme to the skillet with the onions. Season with salt and pepper to taste and cook until the mushrooms are tender, around 5-7 minutes.
Step 4: Preparing the Puff Pastry
Roll out the puff pastry on a lightly floured surface and transfer it to a baking sheet, leaving some overhang around the edges.
Step 5: Filling the Pastry
Spread the caramelized onion and mushroom mixture evenly over the pastry.
Step 6: Adding Cheese
Generously sprinkle the grated Gruyère cheese on top of the filling.
Step 7: Shaping the Tart
Fold the edges of the puff pastry over the filling to create a border around the tart.
Step 8: Applying Egg Wash
Brush the edges of the pastry with the beaten egg to give it a lovely golden color when baked.
Step 9: Baking the Tart
Bake in the preheated oven for 25-30 minutes or until the pastry is golden brown and puffed.
Step 10: Cooling and Serving
Once baked, allow the tart to cool slightly on the baking sheet before slicing and serving.
How to Serve French Onion Mushroom Tart
This tart is best enjoyed warm. Cut it into squares or wedges and serve as a savory appetizer or alongside a fresh salad for a light lunch or dinner. Pair with a crisp white wine like Sauvignon Blanc or a light beer for a delightful meal.
How to Store French Onion Mushroom Tart
To store leftovers, let the tart cool completely, then place it in an airtight container in the refrigerator. It will keep well for up to 3 days. Reheat in the oven at 350°F until warmed through to retain its flaky texture.
Expert Tips for Perfect French Onion Mushroom Tart
