Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Heat 3 tablespoons olive oil in a large skillet over medium heat. Add 2 minced shallots and 3 minced garlic cloves, sauté for 2 minutes until softened and fragrant.
  2. Step 2: Add 12 oz finely chopped cremini mushrooms, 1 teaspoon salt, 1/2 teaspoon black pepper, and 2 teaspoons chopped fresh thyme leaves. Cook over medium heat for 8-10 minutes until mushrooms release moisture and it evaporates, leaving a dry mixture.
  3. Step 3: Remove from heat and let cool slightly. On a floured surface, roll out 2 sheets puff pastry and divide mushroom mixture evenly down the center of each. Sprinkle 2.5 oz crumbled Stilton cheese over mushrooms on each sheet.
  4. Step 4: Fold puff pastry over filling, sealing edges with 1 beaten egg. Brush tops with remaining egg wash and place on a baking sheet.
  5. Step 5: Bake for 25-30 minutes until pastry is puffed and golden brown. Let rest 5 minutes before slicing to serve.
