Step 2 — Make the Duxelles

In a skillet, heat butter and olive oil over medium heat. Add the finely chopped mushrooms and cook until they release moisture and begin to brown. Stir in the onion and garlic, cooking until fragrant and soft. Add thyme, salt, and pepper, then continue to sauté until the mixture becomes thick and paste-like, this is your classic duxelles.

Step 4 —Assemble the Puff Bombs

Preheat your oven to 400°F (200°C). Roll out the puff pastry sheet lightly and cut it into 9–12 squares. Place a spoonful of the filling in the center of each square, then fold the corners over to form little pockets or “bombs.” Press edges gently to seal.

Step 5 — Brush and Bake

Place the puff bombs on a parchment-lined baking tray. Whisk together egg and milk for an egg wash, then brush it over the tops. Bake for 18–22 minutes until puffed, golden, and flaky.

Step 6 —Garnish and Serve

Let cool slightly before serving. Garnish with chopped parsley and an extra sprinkle of Parmesan for a pretty finish. Serve warm and flaky!

Storage Instructions

FAQs

A: Absolutely! Prepare and fill the puff bombs, then refrigerate them unbaked for up to 24 hours. Bake right before serving for the freshest, flakiest texture.

A: You can, but the texture will be different , more delicate and crisp rather than puffy. Use 2–3 sheets of filo per bomb brushed with butter between layers.

Make sure the filling is thick and not watery. Cooking the duxelles properly and cooling the sweet potato mash helps remove excess moisture.

A: Yes! Use vegan puff pastry, skip the egg wash (use plant milk instead), and substitute Parmesan with nutritional yeast or vegan cheese.
