Preparation Phase & Tools to Use
Before embarking on creating these culinary delights, it is crucial to have your kitchen workspace set and ready. Begin by organizing your ingredients and ensuring your oven is preheated to perfection. You’ll need a reliable baking sheet lined with parchment paper to prevent sticking and ease clean-up. A good chef’s knife will be your best friend for chopping mushrooms and onions finely — a task essential for achieving the right texture in your duxelles filling.
Ensure you have a medium-sized pan to sauté your vegetables and evaporate excess moisture. A rolling pin will be necessary for rolling out the puff pastry evenly. Last but not least, keep a pastry brush on hand for applying the egg wash, which gives those puff bombs a satisfying, glossy finish.
Keep your ingredients within reach to streamline the process, and don’t forget to prepare a cooling rack so these delicious bombs don’t lose their crispness upon cooling.

Ingredients
- 1 sheet puff pastry, thawed
- 1 medium sweet potato, roasted and mashed
- 8 oz mushrooms, finely chopped
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 2 tbsp olive oil or butter
- 1 tsp fresh thyme (or ½ tsp dried)
- Salt and black pepper, to taste
- 1 egg, beaten (for egg wash)
Instructions
Step 1: Roast and Mash
Begin by preheating your oven and preparing the sweet potato. Roast it until tender, which usually takes around 30 minutes. Once softened, remove the skin and mash it well, ensuring a smooth texture for integrating into your filling later.
Step 2: Create the Duxelles
As the sweet potato roasts, turn your attention to the mushrooms and onions. Chop them finely and sauté in a pan with olive oil or butter over medium heat. Add in minced garlic and thyme, stirring often. Cook this mixture until most of the moisture evaporates. Season with salt and black pepper to your liking.
Step 3: Combine and Fill
Mix the mashed sweet potato into the mushroom mixture thoroughly. Roll out your puff pastry on a floured surface. Cut the pastry into even squares, placing a spoonful of your filling mixture into the center of each piece. Carefully fold over the edges and seal them to form the bomb shape. Use a little water if needed to help the pastry stick together better.
Step 4: Bake to Perfection
Apply a brush of beaten egg on top of each puff bomb, then transfer them onto your prepared baking sheet. Bake in the oven preheated to 400°F (200°C) for 15-18 minutes until they puff up and turn golden brown. Once done, let them cool slightly on a rack before serving.

Variations
- Protein: Add cooked, crumbled sausage or chunks of roasted chicken to the filling for extra protein.
- Vegetables: Substitute or add finely chopped bell peppers or spinach for a pop of color and nutrition.
- Spices: For a hint of spice, sprinkle in some cayenne pepper or smoked paprika to the filling mixture.
Cooking Notes
- Ensure that your puff pastry is thawed properly before using to prevent tearing when rolling and folding.
- Adjust the seasoning according to your preference, keeping in mind the sweetness of the roasted sweet potato.
Serving Suggestions
- Pair with a fresh, crisp salad for a balanced meal.
- Serve alongside a bowl of tangy yogurt dip or aromatic herb sauce for extra flavor.
Tips
- If the puff pastry becomes too soft or sticky to handle, place it back in the refrigerator to firm up.
- Make a double batch: these puff bombs are freezer-friendly and can be reheated at a moment’s notice.
