Ingredients

  • 3 cups sliced mushrooms
  • 3 large cloves garlic minced
  • 1.5 tablespoon olive oil (divided) extra virgin
  • 2 cups chopped onion
  • 2 tablespoon coconut sugar
  • 1 medium sweet potato cooked, removed from skin & mashed
  • 1 vegan puff pastry thawed for 40 minutes
  • 2 sprigs fresh rosemary
  • 2 tablespoon Dijon mustard
  • sea salt and pepper to taste

For the Vegan Egg Wash

  • 1 tablespoon aquafaba (chickpea water)
  • 1 tablespoon almond milk
  • 1 teaspoon vegetable oil
  • 1 tablespoon maple syrup

Instructions

  • Preheat oven to 375 degrees Fahrenheit (190 degrees Celsius). In a large frying pan over medium heat, add 1 tablespoon olive oil followed by the chopped onion. Saute until translucent, stirring occasionally. 
  • Turn up heat to high and add coconut sugar to onions until they are golden brown. Remove from heat & pan, set aside. 
  • Return pan to heat, add remaining olive oil, garlic, mushrooms, sea salt and pepper and saute until lightly wilted. Remove from heat and place on plate lined w/ paper towels. Fold paper towels around mushrooms and turn over, allowing them to drain. Transfer onions, mushrooms and sweet potato to freezer to cool for 10-15 minutes. 
  • When the veggies are cool, unfold puff pastry on a lined baking sheet. Spread half of caramelized onions over middle third of pasty leaving about ¾ inch (2 cm) on each side. Follow with a layer of mashed sweet potato, then a layer of mushrooms and top with Dijon mustard and sprigs of rosemary. Season with sea salt and pepper, if needed. 
  • Roll the pastry VERY CAREFULLY over the top of the mushroom mixture until it forms a log. Press down on the pastry edges to make a seal. Gently roll the log over so the seam is on the bottom. 
  • To make the vegan egg wash, whisk all the ingredients together in a small bowl. Brush a thin veil of the wash over the top and sides of the pastry. Using a sharp knife, cut zig-zags over the top of the pastry. Place in freezer for 10 minutes, then repeat with another layer of vegan egg wash. 
  • Bake for 40 minutes, depending upon your oven time. Your pastry is done when the crust is golden brown. 

Notes

  • Best served right out of the oven, however, may cover, allow to cool and refrigerate until ready to eat. 
  • If you don't have ingredients for vegan egg wash, just use olive oil. 
  • Cook times will vary, depending upon your oven. Pastry is done when top and sides are golden brown and crust if flaky. 
  • The calorie content is without aquafaba. 
  • To prevent ends from being overdone, place foil over them during the last 10 minutes of the baking process.
