Ingredients

For the Mushrooms:

  • 10 oz assorted mushrooms (white, brown, cremini and/or shiitake mushrooms), sliced about 2 1/2 - 3 cups sliced mushrooms
  • 2 tbsp unsalted butter
  • 3 fresh thyme sprigs
  • 1/2 tsp coarse salt
  • 1/4 tsp ground black pepper

For the Tart:

  • 1 sheet puff pastry dough, thawed
  • 1 1/2 cups shredded gruyere cheese can substitute with swiss cheese
  • 2-3 cups arugula for serving

Instructions

  • **Important: thaw puff pastry according to package directions**
  • Pre-heat the oven to 425F and line a baking sheet with parchment paper.
  • Role out the puff pastry dough into a 10 inch by 12 inch rectangle (approximately). Make a half-inch border around the tart by rolling/pinching the sides of the dough. Using a fork, make dots throughout the middle of the tart and then set aside.
  • To make the mushrooms, melt 2 tbsp butter in a frying pan over medium heat.
  • Once the butter is bubbling, add in the garlic and give it a quick stir. Then add in the sliced mushrooms. Cook the mushrooms for 5 minutes, stirring occasionally.
  • Add in thyme sprigs, salt and pepper to the mushrooms and cook for another 5 minutes, stirring often and until the mushrooms are softened. Remove the thyme sprigs and then set mushrooms aside.
  • Spread 1 cup of cheese onto the tart and bake for 10 minutes. Then remove from the oven. (Note: the middle of the tart may start to puff up a bit so when removing the tart after 10 minutes, just use a fork to make a couple more dots in the tart to get the air out)
  • Spread the mushrooms out evenly onto the baked cheese layer of the tart, then layer 1/2 cup remaining cheese on top of the mushrooms. Bake the tart for 12-15 more minutes until the crust is golden.
  • Top with arugula and enjoy!
