Instructions

Preparation: Gather all ingredients and preheat your oven to 400°F. Place a baking sheet inside the oven to heat. Line another baking sheet with parchment paper where you will place the Wellington later.
Cooking the Filling: Finely chop the mushrooms. In a skillet over medium heat, sauté the mushrooms in butter and olive oil for about 10 minutes until softened. Add finely chopped shallots, minced garlic, fresh thyme, rosemary, and sage, cooking until the mixture is fragrant and fragrant herbs are released.
Enhancing Flavors: Stir in the soy sauce and balsamic vinegar to the mixture, then mix in the panko breadcrumbs and Parmesan cheese. Cook together briefly, then transfer the mixture to a bowl and let it cool completely to prevent pastry from becoming soggy during assembly.
Searing Portobellos: Pat the Portobello caps dry with paper towels. Heat a skillet and sear the caps on each side for about 5 minutes or until they develop a nice brown crust. Remove from heat and brush each cap with Dijon mustard to infuse extra flavor.
Assembling the Wellington: On a lightly floured surface, roll out the puff pastry sheet. Evenly spread the cooled mushroom duxelles mixture on the pastry. If using, layer baby spinach over the duxelles, then place the seared Portobello caps on top. Spread another layer of the duxelles over the caps. Carefully fold and seal the pastry edges to enclose the filling completely. Chill the assembled Wellington in the refrigerator for 15-20 minutes to help it hold shape.
Baking: Remove the preheated baking sheet from the oven and transfer the chilled Wellington onto it. Brush the pastry with the beaten egg wash to achieve a glossy golden crust. Bake at 400°F for 20 minutes. Then reduce the oven temperature to 375°F and bake for an additional 15-20 minutes until the pastry is deeply golden and cooked through.
Serving: Allow the Wellington to rest for 10-15 minutes after baking to let the juices settle and make slicing easier. Serve warm, ideally accompanied by vegetarian gravy or a balsamic reduction for a rich finishing touch.

Notes

For a vegan version, substitute butter with vegan butter, Parmesan cheese with nutritional yeast, and use non-dairy milk for egg wash or simply skip the wash.
Ensure the filling mixture is completely cooled before assembling to prevent the pastry from becoming soggy.
Chilling the assembled Wellington before baking helps the pastry maintain its shape and bakes more evenly.
You can substitute the mushrooms with oyster or shiitake mushrooms for varied texture and flavor depth.
If gluten-free is a concern, use gluten-free puff pastry and tamari instead of soy sauce.
Serve with complementary sauces such as vegetarian gravy or balsamic reduction for added flavor layers.
