Mushroom Tart: a flakey puff pastry topped with balsamic caramelized onions, sautéed garlicky mushrooms, and topped with whatever you'd like! A definite crowd-pleaser.

Now, I know what some of you are thinking…mushrooms?! I'm not really into mushroom recipes either but just TRUST me on this one. I chopped those mushrooms up really small and cooked them in garlic goodness. This mushroom tart is flaky and savory and can be topped with a variety of toppings. This appetizer with puff pastry is perfect for a mid-day snack or for a holiday party. I just made these for Thanksgiving and topped them with some seasoned ricotta...YUM! Even my fellow anti-mushroom family members enjoyed the tart.

Benefits of Mushrooms:

  • They're a good source of potassium
  • Contain B vitamins
  • Have antioxidant and anti-inflammatory benefits

How to make this Savory Puff Pastry Tart

  • We grab a puff pastry and thaw it out according to the package. I like to use these puff pastry sheets.
  • Make the mushroom and onion saute.
    • Cook the onions in balsamic goodness until they're caramelized.
    • Sauté those chopped-up mushrooms with some garlic.
  • Cool the mixture and top it on the puff pastry. Score the edges (score just means to make a slit in the puff pastry but don't cut it all the way through!). Bake it, cut it, and serve!

I topped mine with chopped spinach. If you're not vegan, we really enjoyed these with some seasoned ricotta cheese!
