White Cheddar, Onion & Mushroom Puff Pastry Tart
Delicious mushroom and onion puff pastry tart that tastes just as amazing as it looks! Golden brown puff pastry topped with savory French onion dip, pools of melty white cheddar cheese, and perfectly cooked onions and mushrooms. Perfect for a holiday gathering or a casual get-together and can be served with dinner or brunch.
Ingredients
- 1 puff pastry sheet thawed but cold
- ¼ cup French onion dip (I like to use Old Home)
- 1 ½ cups white cheddar cheese shredded
- 1 large yellow onion thinly sliced
- 2-3 baby bella mushrooms thinly sliced
- Olive oil for drizzling
- Balsamic vinegar for drizzling
- Red pepper flakes to taste (optional)
- Salt and pepper to taste
- 1 egg beaten
- fresh thyme for garnishing (optional)
Instructions
- Preheat the oven to 400°F.
- On a lightly floured surface, roll out the puff pastry into a 10x12 inch rectangle, then transfer to a parchment lined baking sheet. Use a knife to score a ½ inch border around all sides of the puff pastry, but do NOT cut all the way through.
- Prick the inside of the pastry all over with a fork.
- Spread the French onion dip evenly over the pastry, staying within the score lines. Sprinkle with cheese, then top with slices of onion and mushroom. Drizzle with olive oil and balsamic vinegar. Season with red pepper flakes, salt, and pepper.
- Brush the edges of the pastry with egg, staying outside the score lines.
- Bake for 20-25 minutes until the pastry is golden brown.
- Garnish with fresh thyme, cut into 6-8 slices, and enjoy while warm!
