Mushrooms & Marinade

Method

Mushrooms & Marinade

  1. 1

    Prepare mushrooms

    Clean the mushroom caps by gently wiping with a damp paper towel or soft brush. Remove stems and set caps aside. If stems are large, reserve for another use or finely chop and add to the filling (adjust filling quantity if you do).

  2. 2

    Make marinade

    In a medium bowl whisk together 1/2 cup olive oil, white wine vinegar, soy sauce, honey, minced garlic (3 cloves), lemon juice, thyme, red pepper flakes, kosher salt and black pepper until combined.

  3. 3

    Marinate mushrooms

    Place mushroom caps in a single layer in a shallow dish or resealable bag. Pour half of the marinade over the caps, turning to coat well. Reserve the other half of the marinade for basting later. Marinate at room temperature for 20–30 minutes or refrigerate for up to 2 hours. Turn occasionally so caps absorb marinade evenly.

Filling

  1. 4

    Cook spinach

    Heat 1 tablespoon butter in a large skillet over medium heat. Add the finely chopped shallot and sauté 2–3 minutes until softened. Add 1 minced garlic clove and cook 30 seconds until fragrant. Add packed spinach in batches, stirring until wilted and liquid evaporates, about 4–6 minutes total. Remove from heat and transfer spinach to a colander; press gently with a spoon to remove excess moisture. Allow to cool slightly and then chop coarsely.

  2. 5

    Combine filling

    In a mixing bowl, combine the cooled chopped spinach, 8 oz small pieces of Brie (if Brie is very soft, remove the rind or keep small pieces), 2 oz softened cream cheese, 2 tablespoons grated Parmesan, 1/8 teaspoon freshly grated nutmeg, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1 teaspoon lemon zest. Mix until uniform — the mixture should be thick and spreadable. Taste and adjust seasoning.

  3. 6

    Portion filling

    Using a small spoon or piping bag, portion about 1 tablespoon of filling into each marinated mushroom cap, mounding slightly but not overflowing. If you have leftover filling, reserve for serving or reduce per-cap amount.

Bake & Finish

  1. 7

    Arrange

    Preheat oven to 375°F (190°C). Arrange the filled mushroom caps on a baking sheet lined with parchment or in a shallow baking dish, gill-side up. Brush or drizzle each cap with a little of the reserved marinade or 1–2 teaspoons olive oil.

  2. 8

    Bake

    Bake for 12–16 minutes, until filling is bubbly and Brie has softened and started to turn golden at the edges. If you prefer a crisper top, place under a broiler for 1–2 minutes while watching carefully.

  3. 9

    Garnish and serve

    Remove from oven and let rest 3–4 minutes. Sprinkle chopped parsley and toasted pine nuts over the mushrooms, and drizzle a little extra olive oil if desired. Serve warm or at room temperature as an appetizer or alongside a salad.
