These French onion and portobello mushroom pinwheels are a little holiday treat and they were the perfect appetizer for my tree decorating party.

I call them French Onion just for the fact that they taste exactly like French Onion Soup wrapped in beautiful, yummy puff pasty. The mushrooms add an extra savory dimension that works perfect with the flavor of French Onion.

They’re so easy to prepare and the ingredients are easily interchangeable. Play around with your favorite flavors with this recipe. Caramelized onions pair well with anything really. Wilted spinach would work really well here. I was thinking roasted butternut squash and sage would be delicious and festive as well.

Bonus Tip: Make extras and freeze unbaked pinwheels for tasty treats anytime. Just freeze on a baking sheet until firm, tightly wrap in plastic wrap and place in a ziploc freezer bag. When ready to bake just pop into the oven straight from the freezer, no need to thaw. Just add a few more minutes to the baking time.

French Onion and Portobello Mushroom Pinwheels

Ingredients

  • 1 package {2 sheets} Frozen Puff Pastry, thawed {I used Pepperidge Farm.}
  • 2 tablespoons Olive Oil
  • 2 tablespoons Butter
  • 1 large Sweet Onion, thinly sliced
  • 1 package Baby Portobello Mushrooms, thinly sliced
  • 2 tablespoons Cognac {I used Hennessey.}
  • 2 cloves Garlic, minced
  • 1 tablespoon Thyme Leaves, chopped
  • 1 bunch Parsley, chopped
  • 1/2 Sharp White Cheddar Cheese, grated
  • 1 cup Gruyere Cheese, grated
  • 1/2 cup Parmesan Cheese, grated
  • Kosher Salt and Black Pepper
  • 1 whole Egg, beaten
  • 1 tablespoon Water

Instructions

  1. Preheat your oven to 400 degrees F. Prepare two sheet pans. Place a piece of parchment paper on each sheet pan. Set aside.
  2. In a medium skillet heat the oil and butter over medium heat. Add the sliced onions to the pan and season with salt to help bring out the sugars in the onions to caramelize. Stir over medium heat until edges of the onion are turning golden. Caramelizing onions takes a good 20 minutes, stir until onions are golden brown. Add the mushrooms and cook until tender and browned, about 5 minutes.
  3. Deglaze the pan with 2 tablespoons of cognac and scrape up any browned bits on the bottom of the pan. Add the garlic and thyme stir until fragrant, about 30 seconds. Season with salt and pepper. Turn heat off and remove pan to cool slightly. Toss in chopped parsley to the onions and mushrooms.
  4. Combine grated cheeses in a separate bowl. Lay 1 sheet of puff pastry on a floured surface and carefully roll it out to 10 by 12 inches. Make sure to keep your puff pastry chilled before using. It’s much easier to handle if you store in the fridge until you need it.
  5. Whisk together the egg and tablespoon of water. Brush the puff pastry with the egg wash.
  6. Add a layer of onions and mushrooms on the bottom, leave a 1/2 inch border on all sides. Top with grated cheeses. Roll up like a jelly roll. Cut into 8 – 12 (1/2-inch) slices with a sharp slicing knife.
  7. {Repeat the process with the other pastry sheet.}
  8. Carefully place the round slices on two baking sheets. Pat down slightly to flatten and shape. Brush the tops with egg wash. Bake for 20 – 25 minutes or until the pinwheels are golden brown.
  9. Allow to cool slightly before serving. Enjoy!

Caramelizing onions takes a good 20 minutes, but if you want to speed up the process I like adding a tablespoon of brown sugar or honey at this point. You won’t believe how fast it caramelizes. Stir until onions are golden.

Add the mushrooms and cook until tender and browned, about 5 minutes.
