Wild Mushrooms en Papillote (Vegan or Vegetarian)

They're not your father's Freedom Fries

You might have noticed a recurring theme. I’m way batty for mushrooms.

This time I decided to break away from my normal preferred mushroom cooking method and try something different. It’s a slight adaptation of a gem from my home skillet Billy S and certainly an easy way to cook mushrooms if for some reason you find it impractical to saute them on the stove top. The only thing is that I’m not sure if there’s any real advantage to preparing your mushrooms en papillote, other than to sound French, impress Martha Stewart or delight your guests with mushrooms from a paper bag. Some say that this method is healthier because it cuts down on the amount of oil you cook with, but a) you’re replacing it with butter or margarine; and b) cooking mushrooms stove top doesn’t really call for all that much oil. So I don’t know what that’s about. One thing I can say is that cooking your mushrooms this way will result in slightly softer, less browned mushrooms, so if you’re trying to control texture and presentation, that could be a reason to choose the papillote method.

Three important departures from the Billy Sonoma version that I’ve included here: 1) Omitted the parsley because I was serving them in an arugula salad and didn’t need the extra bitterness; 2) After steaming them in the parchment for about 10 minutes, I opened up the bag to dry them out a bit, because they had produced quite a bit of moisture, as we all know our fungus friends are wont to do; 3) Added red pepper flakes, because you know I love the spicy, yo.

One last thing. If you’re wondering where you can get your hands on some parchment, you can find it in most grocery stores in the aisle with aluminum foil and wax paper.

Wild Mushrooms en Papillote

  • 1 tbsp vegan butter or unsalted butter, plus 1 tbsp vegan butter or unsalted butter, cut into small pieces
  • 1 lb mushrooms, brushed clean – I used shiitake, trumpet and almond mushroom (random farmer’s market find), but you could use any combination of mushrooms you like
  • 1/2 tsp ground sea salt
  • 1/4 tsp freshly ground pepper
  • Red pepper flakes, to taste
  • 1 tsp fresh lemon juice

Preheat an oven to 375°F.

Cut parchment paper into an 18-by-11-inch rectangle. Fold the rectangle in half crosswise. Open the parchment and coat with the 1 tbsp butter. Place the rectangle, buttered side up, on a baking sheet.

Cut the mushrooms into bite-size pieces and place in a bowl. Add the salt, pepper, butter pieces, lemon juice and toss well. Spread the mushrooms over one half of the prepared parchment paper. Fold the other half of the parchment rectangle over the mushrooms and fold the vertical edges over twice, working your way along the edge of the paper to end with a twist on both ends. Place the package on a rimmed baking sheet.

Bake until the parchment packet is puffed and the mushrooms are cooked through, about 10 – 12 minutes. At that point, do a progress check – have they thoroughly juiced? If so, go ahead and carefully open up the parchment and return them to the oven for another 1 – 3 minutes to dry out any lingering liquids. Transfer the parchment packet to a platter and serve immediately. (Or, if you’re making a salad, add them to the salad and serve immediately. More on the salad coming soon.)
