Mushroom Wellington with Puff Pastry Ingredients

For the Mushroom Filling

  • Mixed mushrooms – choose a variety like cremini, shiitake, and portobello for depth of flavor.
  • Shallots – finely chopped to add a sweet, mild onion flavor.
  • Garlic cloves – minced to infuse the filling with aromatic warmth.
  • Fresh thyme – use whole leaves for an earthy herbal note that complements the mushrooms.
  • Olive oil – for sautéing, ensuring the mushrooms cook evenly and develop a rich taste.
  • Salt and black pepper – essential for seasoning and enhancing the natural flavors.

For the Puff Pastry and Assembly

  • Ready-rolled puff pastry sheet – look for all-butter pastry to achieve the flakiest, golden crust.
  • Dijon mustard – brushed on the pastry for a subtle tang that balances the richness.
  • Egg yolk – beaten for glazing to give the pastry a beautiful sheen and golden color.

Optional Add-ons

  • Spinach leaves – lightly sautéed to add a fresh, green layer beneath the mushrooms.
  • Walnuts or pecans – chopped and toasted, adding crunch and a nutty flavor dimension to the Mushroom Wellington with Puff Pastry.

How to Make Mushroom Wellington with Puff Pastry

For the Mushroom Filling:

  1. Heat oil: In a large skillet over medium heat, warm the olive oil until it shimmers gently, about 1 minute. This ensures an even sizzle and enhances the filling’s rich flavor.
  2. Sauté shallots and garlic: Add shallots and garlic to the pan, stirring constantly until they soften, become fragrant, and turn translucent, about 2–3 minutes. This builds a sweet, aromatic base.
  3. Cook mushrooms: Toss in the mixed mushrooms and fresh thyme, then cook over medium-high heat, stirring occasionally until the mushrooms release their juices and brown beautifully, about 8–10 minutes.
  4. Season filling: Sprinkle in salt and freshly ground black pepper, stir for another minute, then remove from heat and let the mixture cool slightly before assembly.

Assembly & Baking:

  1. Preheat oven: Set oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup and even baking.
  2. Prepare pastry: Unfold the puff pastry on a lightly floured surface, then brush the edges with Dijon mustard, leaving a 1-inch border to seal the Wellington perfectly.
  3. Fill and fold: Pile the cooled mushroom filling down the pastry center, fold the edges over, and crimp the seams to create a neat, rectangular package.
  4. Glaze and bake: Transfer the Wellington to your sheet, brush the surface with beaten egg yolk, then bake until puffed and golden brown, about 25–30 minutes.

Optional: Serve with a dollop of crème fraîche or fresh herb salad.

Expert Tips for Mushroom Wellington with Puff Pastry

  • Choose fresh mushrooms: Use a mix of fresh, firm mushrooms to avoid soggy filling and achieve the best earthy flavor in your Mushroom Wellington with Puff Pastry.
  • Cook mushrooms thoroughly: Sauté until all moisture evaporates to prevent a soggy crust and concentrate the savory taste.
  • Cool filling before wrapping: Let the mushroom mixture cool completely to stop the pastry from steaming and losing its crispness.
  • Seal edges well: Brush the pastry edges with mustard and press firmly to prevent leaks during baking, keeping your Wellington neat and golden.
  • Use an egg wash: Glazing with beaten egg yolk ensures a beautiful shiny, golden crust that elevates the dish’s presentation.
  • Avoid overfilling: Keep the filling in a compact layer to maintain structure and ensure even cooking without bursts or cracks.

Make Ahead Options

These Mushroom Wellington with Puff Pastry are a game-changer for meal prep enthusiasts! You can prepare the mushroom filling up to 3 days in advance; just sauté the mushrooms, shallots, and garlic as directed, let it cool, then store it in an airtight container in the refrigerator. To keep the puff pastry from getting soggy, assemble the Wellington (with the filling) up to 24 hours ahead—wrap tightly in plastic wrap and refrigerate. When you’re ready to serve, simply brush with egg yolk and bake. This way, you’ll have a stunning, flavorful dish with minimal effort on the day of your gathering, and it will taste just as delicious as if you made it fresh!

Mushroom Wellington with Puff Pastry Recipe FAQs

What kind of mushrooms work best for Mushroom Wellington with Puff Pastry?
A mix of cremini, shiitake, and portobello mushrooms works wonderfully, offering a deep, earthy flavor. Fresh, firm mushrooms are essential to avoid sogginess and enhance the richness of the filling.

How should I store leftover Mushroom Wellington?
Store leftovers in an airtight container in the fridge for up to 3 days. When reheating, avoid the microwave to keep the pastry crispy; instead, warm it in the oven at 350°F (175°C) for about 10–15 minutes.

Can I freeze Mushroom Wellington, and how do I do it properly?

Why does my puff pastry sometimes get soggy after baking with mushrooms?
This is usually because the mushrooms release too much moisture. To prevent sogginess, cook the mushroom filling thoroughly until all liquid evaporates and let it cool completely before wrapping it in the pastry. Also, brushing a layer of Dijon mustard on the pastry edges helps create a moisture barrier.
