Puff Pastry Mushroom Tart Recipe

Cook Time: 20 minutes

Servings: 6

Preparation Time: 15 minutes

Cooking Time: 20 minutes

Ingredients

• 12 ounces cremini mushrooms, such as Baby Bella
• 1/2 red onion, sliced vertically
• 1 tablespoon olive oil
• 1 tablespoon unsalted butter
• 2 tablespoons low-sodium soy sauce
• 1 teaspoon dried thyme
• 2 garlic cloves, minced
• Salt and freshly ground black pepper to taste
• 1/2 (17.3 ounce) package frozen puff pastry, thawed
• 1 1/2 cups shredded Gruyere cheese
• 1 large egg, beaten
• 1 teaspoon dried thyme, or as needed for garnish (optional)

Directions

Step 1: Preheat the oven to 400F (200C) and line a baking sheet with parchment paper.

Step 2: Slice the mushrooms into 1/4-inch thick pieces, avoiding overly thin slices for a more substantial texture.

Step 3: In a large skillet, heat the olive oil and butter over medium heat. Add the sliced mushrooms and red onion, stirring occasionally. Cook for about 6 to 8 minutes, or until the mushrooms are golden and the onions have softened and become translucent.

Step 4: Stir in the soy sauce, dried thyme, and minced garlic. Cook for another 30 to 60 seconds until fragrant. Season with salt and freshly ground black pepper to taste, then set aside to cool slightly.

Step 5: Unfold the puff pastry on a lightly floured surface. Roll it out gently into a square about 10x10 inches in size. Using a sharp knife, score a border about 1/2 inch from all edges, being careful not to cut all the way through. Use a fork to prick the inside of the pastry generously.

Step 6: Transfer the puff pastry to the prepared baking sheet. Brush the edges with the beaten egg to create a golden, shiny finish once baked.

Step 7: Sprinkle the shredded Gruyere cheese evenly inside the border, then top with the mushroom and onion mixture.

Step 8: Bake in the preheated oven for 10 to 12 minutes, or until the tart is puffed up and lightly browned.

Step 9: Garnish with additional thyme if desired and serve the tart warm.

Cook's Note

If you cant find Gruyere cheese, Swiss cheese is an acceptable substitute, though it may not have the same depth of flavor as Gruyere.
