Ingredient Notes

• Mushrooms
  Use a mix like cremini, portobello, or button mushrooms. Mixing types adds depth. Chop them small so the filling holds together well.

• Puff Pastry
  Store-bought puff pastry saves time. Thaw it in the fridge, not at room temp.

• Onion or Shallots
  These add sweetness and help balance the mushrooms.

• Garlic
  Fresh garlic boosts flavor without overpowering.

• Butter and Olive Oil
  Using both gives flavor and prevents burning.

• Breadcrumbs
  Help absorb moisture so the pastry stays crisp.

• Fresh Herbs
  Thyme and parsley work best. Dried herbs can be used in smaller amounts.

• Egg
  Used for egg wash to get that golden color.

Special equipment needed: baking sheet, parchment paper, skillet

How To Make Golden Mushroom Wellington with Puff Pastry

1. Prepare the Mushroom Filling

Heat 1 tablespoon olive oil and 1 tablespoon butter over medium heat.
Add chopped onion and cook for 5–6 minutes until soft and lightly golden.

2. Cook the Mushrooms

Add 500 g chopped mushrooms to the pan.
Cook for 10–12 minutes, stirring often, until moisture cooks off and mushrooms turn deep brown.

Look for a dry pan and rich color (this step matters for flavor).

3. Add Flavor

Stir in 2 cloves minced garlic, 1 teaspoon fresh thyme, salt, and pepper.
Cook for 1 minute until fragrant.

4. Finish the Filling

Add ½ cup breadcrumbs and chopped parsley.
Stir well and remove from heat.
Let filling cool fully before assembling (hot filling melts pastry).

5. Prepare the Pastry

Preheat oven to 200°C (400°F).
Roll puff pastry on lightly floured surface into a rectangle.

6. Assemble the Wellington

Place mushroom filling in the center, shaping into a log.
Fold pastry over and seal edges tightly underneath.

7. Egg Wash and Score

Brush with beaten egg.
Score the top lightly for steam release and decoration.

8. Bake

Bake for 35–40 minutes until deep golden and puffed.
Rest for 10 minutes before slicing.
