Ingredients
  

Poached Mushrooms

  • 1 cup olive oil
  • 16 oz mushrooms
  • 2 garlic cloves
  • 1 tablespoon of fresh thyme
  • 1 teaspoon salt
  • 1 teaspoon sugar

Mushroom Marinade

  • 3 tablespoons minced shallots from about 2 large shallots
  • 1 large garlic clove minced
  • 2 tablespoons finely chopped parsley leaves
  • 1 teaspoon thyme leaves
  • ½ teaspoon lemon zest
  • ½ teaspoon red pepper flakes or Aleppo pepper
  • 3 tablespoons red wine vinegar
  • 1 tablespoon lemon juice
  • ½ cup extra-virgin olive oil that mushrooms were cooked in

Instructions
 

Poach mushrooms

  • Bring the olive oil to a slight simmer and reduce to medium. Do not boil.
  • Add the mushrooms, salt, sugar, garlic, and thyme. Cook until the exterior of the mushrooms soften, 6-7 minutes. The mushrooms will shrink.
  • Remove from heat and let it cool.

Make mushroom marinade

  • Meanwhile make the marinade, by mixing together all of the marinade ingredients: 3 tablespoons of minced shallots, 1 minced garlic clove, 2 tablespoons of finely chopped parsley leaves, 1 teaspoon fresh thyme leaves, ½ teaspoon lemon zest, 1 tablespoon lemon juice, and 3 tablespoons red wine vinegar, red pepper flakes (if using)
  • Add the mushrooms and the poaching liquid (the olive oil) to the marinade. Because the mushrooms are cooked and infused with the olive oil, you can totally dig in, but they will get even better if they chill overnight in your fridge. You can make these up to a week in advance!
