Ingredients & Preparation Notes

- Chestnuts: Cooked and roughly chopped chestnuts add a unique texture and nutty flavor. You can use vacuum-packed or roasted chestnuts.
- Mushrooms: Sliced mushrooms bring an earthy taste and meaty texture to the pie. Use a mix of varieties for depth of flavor.
- Kale: Remove the stems and chop the kale to ensure it cooks down well and integrates into the filling.
- Thyme: Fresh thyme adds a subtle, aromatic flavor that complements the other ingredients.
- Soy sauce: Enhances the umami flavor of the filling; use low-sodium if preferred.
- Vegetable broth: Choose a good quality broth to enhance the overall taste of the pie.
- Cornstarch: Mixed with water, this helps thicken the filling without altering the flavor.
- Puff pastry: Thaw the pastry according to package instructions for the best results.
- Egg: Beaten egg creates a golden, glossy finish on the crust. For a vegan option, use plant-based milk.
Professional Tips & Techniques
- Temperature Control: Ensure your oven is preheated to 375°F (190°C) for even baking. A consistent temperature helps the pastry rise and brown evenly.
- Filling Consistency: The cornstarch mixture should be added gradually to the simmering filling to avoid lumps. Stir continuously until thickened.
- Pastry Handling: Work with cold puff pastry to prevent it from becoming too soft and difficult to handle. If it starts to warm up, chill it briefly before continuing.
- Visual Cues: The pie is done when the pastry is golden brown and the filling is bubbling. If the crust browns too quickly, cover it with foil to prevent burning.
- Cooling Time: Allowing the pie to cool for 10 minutes before serving helps the filling set and makes slicing easier.
Recipe Variations
- Vegan Option: Substitute the egg wash with plant-based milk or a vegan egg wash alternative. Ensure the puff pastry is vegan-friendly.
- Gluten-Free Option: Use gluten-free puff pastry and ensure all other ingredients are gluten-free.
- Cheese Addition: Add a layer of grated cheese, such as cheddar or gruyere, between the filling and the pastry for an extra indulgent touch.
- Herb Variations: Experiment with different herbs like rosemary or sage to change the flavor profile.
- Nut-Free Option: Substitute chestnuts with roasted butternut squash for a similar texture and sweetness.
- Meat Addition: For non-vegetarians, add cooked, crumbled sausage or bacon to the filling for added richness.
- Spicy Kick: Include a diced jalapeño or a pinch of red pepper flakes for a spicy version.
- Seasonal Twist: In spring, replace kale with spinach and add asparagus for a lighter, seasonal variation.
Serving Suggestions
- Side Dishes: Serve with a side of roasted root vegetables or a simple green salad to balance the richness of the pie.
- Presentation: Garnish with fresh thyme sprigs or a sprinkle of chopped parsley for an elegant touch.
- Pairing: Pair with a glass of red wine, such as a Pinot Noir, to complement the earthy flavors of the pie.
- Family Style: Serve the pie family-style, allowing everyone to enjoy a generous slice. It’s perfect for gatherings and potlucks.
Storage & Make-Ahead Tips
- Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days.

Kale, Chestnut and Mushroom Pie
Equipment
- Large skillet
- Pie dish
- Rolling Pin
- Pastry brush
Ingredients
- 2 tbsp Olive oil
- 1 large Onion finely chopped
- 2 cloves Garlic minced
- 8 oz Chestnuts cooked and roughly chopped
- 10 oz Mushrooms sliced
- 4 cups Kale stems removed and chopped
- 1 tbsp Fresh thyme chopped
- 1 tbsp Soy sauce
- 1 cup Vegetable broth
- 2 tbsp Cornstarch mixed with 2 tbsp cold water
- 1 sheet Puff pastry thawed if frozen
- 1 Egg beaten, for egg wash
Instructions
- Preheat your oven to 375°F (190°C). In a large skillet, heat the olive oil over medium heat. Add the onion and sauté until translucent, about 5 minutes.
- Add the garlic and cook for another minute until fragrant. Stir in the chestnuts and mushrooms, cooking until the mushrooms release their moisture and start to brown, about 8 minutes.
- Add the kale and thyme, cooking until the kale wilts, about 3-4 minutes. Pour in the soy sauce and vegetable broth, bringing the mixture to a simmer.
- Stir in the cornstarch mixture and cook until the filling thickens, about 2-3 minutes. Season with salt and pepper to taste. Remove from heat and let cool slightly.
- Roll out the puff pastry on a lightly floured surface to fit your pie dish. Transfer the pastry to the dish, allowing some overhang. Pour the cooled filling into the pastry.
- Fold the overhanging pastry over the filling, creating a rustic edge. Brush the top with the beaten egg to create a golden crust.
- Bake in the preheated oven for 30-35 minutes, or until the pastry is golden and the filling is bubbling. Let the pie cool for 10 minutes before serving.
