Ingredients

  • 4 large portobello mushrooms, stems removed
  • 3 tbsp olive oil
  • 4 cloves garlic cloves, minced
  • 1 large shallot, finely diced
  • 1 lb mixed mushrooms (cremini, shiitake, oyster), finely chopped
  • 2 tbsp fresh thyme leaves
  • 2 tsp fresh rosemary, finely chopped
  • 2 tbsp Dijon mustard
  • 4 cups fresh spinach
  • 1/2 cup panko breadcrumbs
  • 2 sheets puff pastry sheets, thawed
  • 1 egg, beaten with 1 tbsp water
  • to taste kosher salt
  • to taste freshly ground black pepper
  • 4 oz soft goat cheese (optional), crumbled
  • 1/4 cup balsamic glaze (for serving)

Instructions

  1. 1

    Preheat oven to 400°F (200°C).

  2. 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.

  3. 3

    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. 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. 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. 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. 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. 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. 9

    Spoon the mushroom-spinach mixture on top of and around the portobello, creating a compact mound.

  10. 10

    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.

  11. 11

    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.

  12. 12

    Bake for 30-35 minutes, until the pastry is golden brown and crisp. Allow to rest for 5 minutes before serving.

  13. 13

    Slice the wellington carefully and serve with a drizzle of 1/4 cup balsamic glaze (for serving).

Questions

Can I make Mushroom Wellington dairy-free?

Yes. The dairy in this entry is 4 oz soft goat cheese (optional), crumbled. Swap the cheese for a plant-based melting cheese (expect a milder flavor). The richness shifts slightly, but the method does not change.

Can I make Mushroom Wellington gluten-free?

Not cleanly. 1/2 cup panko breadcrumbs, 2 sheets puff pastry sheets, thawed has no substitute that behaves the same way in this dish. If you need strictly gluten-free, start from the gluten-free dinner collection instead.

How long does Mushroom Wellington keep?

Refrigerate leftovers within two hours and eat them within three days. Reheat covered in a 300 F oven until warmed through.

Can I halve or double Mushroom Wellington?

Yes. As written it serves 4. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. Doubled, split it across two pans and rotate them halfway; one crowded pan bakes unevenly.
