Instructions
-
1
Preheat oven to 400°F (200°C).
-
2
Brush the 4 stems removed large portobello mushrooms with 1 tablespoon of olive oil and season both sides with to taste kosher salt and to taste freshly ground black pepper. Place them gill-side down on a baking sheet and roast for 10-12 minutes until they begin to soften and release some moisture. Remove from oven and set aside to cool.

Meanwhile, heat the remaining 3 tbsp olive oil in a large skillet over medium heat. Add the 1 large finely diced shallot and cook for 2-3 minutes until softened. Add the 4 cloves minced garlic cloves and cook for another 30 seconds until fragrant.
-
4
Add the chopped 1 lb finely chopped mixed mushrooms (cremini, shiitake, oyster) to the pan and cook for 5-7 minutes, stirring occasionally, until they have released their moisture and begin to brown. Add the 2 tbsp fresh thyme leaves and 2 tsp finely chopped fresh rosemary and continue cooking until most of the liquid has evaporated, about 2-3 more minutes.
-
5
Stir in the 4 cups fresh spinach and cook until wilted, about 1-2 minutes. Remove from heat and transfer the mixture to a bowl to cool slightly.
-
6
Once the mushroom mixture has cooled, stir in the 1/2 cup panko breadcrumbs and 4 oz crumbled soft goat cheese (optional) (if using). Season with additional kosher salt and freshly ground black pepper to taste.
-
7
Place a sheet of 2 sheets thawed puff pastry sheets on a lightly floured surface and roll out slightly to increase the size by about 1 inch all around.
-
8
Spread the 2 tbsp Dijon mustard over the center of the pastry, leaving a 2-inch border. Place a roasted portobello mushroom cap, gill-side up, in the center of the pastry.
-
9
Spoon the mushroom-spinach mixture on top of and around the portobello, creating a compact mound.

Fold the pastry edges over the filling, pleating as you go to create a sealed package. If using a second sheet, place the second portobello and filling on that sheet and fold similarly.

Carefully transfer the wellington(s) to a parchment-lined baking sheet, seam-side down. Cut three small slits in the top to allow steam to escape. Brush the entire surface with the beaten 1 beaten with 1 tbsp water egg wash.
