ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

• 2 sheets vegan puff pastry, thawed
• 2 medium potatoes, peeled and diced
• 1 tablespoon olive oil
• 1 medium onion, thinly sliced
• 1/2 teaspoon garlic powder
• Salt and pepper to taste
• 1/2 cup shredded vegan cheese
• 1 tablespoon plant-based milk (for brushing)
• 1 tablespoon sesame seeds or everything bagel seasoning
• Fresh oregano or thyme (optional, for garnish)

directions

1. Boil the diced potatoes in salted water until fork-tender, about 10–12 minutes. Drain and mash with garlic powder, salt, and pepper. Set aside.
2. While the potatoes cook, heat olive oil in a skillet over medium-low heat. Add sliced onions and cook for 10–15 minutes, stirring occasionally, until caramelized.

4. Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
5. Roll out the puff pastry sheets and cut into even 3×3 inch squares.
6. Place a spoonful of the potato filling in the center of half the squares. Top with the remaining squares, pressing the edges with a fork to seal.
7. Brush the tops of the pastries with plant-based milk and sprinkle with sesame seeds or everything bagel seasoning.
8. Bake for 18–22 minutes, or until the pastries are golden brown and puffed.
9. Let them cool slightly. Garnish with fresh herbs if desired and serve warm.

Variations

• Add greens: Stir chopped cooked spinach or kale into the filling for added nutrients.
• Make it spicy: Add a pinch of chili flakes or a dash of hot sauce to the mashed potatoes.
• Use different cheese: Try a smoked vegan cheese for a bolder flavor.
• Mini version: Cut smaller pastry squares for bite-sized appetizers.
• Add protein: Incorporate crumbled tofu or vegan sausage into the filling.

storage/reheating

Store cooled pastries in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F (175°C) oven for 8–10 minutes until warmed through and crispy. Avoid microwaving as it can make the pastry soggy. You can also freeze unbaked pastries and bake straight from frozen, adding a few extra minutes to the baking time.

FAQs

Can I use homemade puff pastry?

Yes, homemade vegan puff pastry works well if you have the time. Ensure it’s rolled thin enough for crispness.

What type of vegan cheese melts best?

Shredded mozzarella-style or cheddar-style vegan cheeses tend to melt well and complement the filling flavor.

Can I make these pastries ahead of time?

Yes, you can assemble the pastries and refrigerate them for a few hours before baking, or freeze them for later use.

Are these pastries freezer-friendly?

Absolutely. Freeze them unbaked or baked. Reheat in the oven to maintain the texture.

Can I use sweet potatoes instead?

Yes, mashed sweet potatoes offer a deliciously sweet and creamy twist.

Do I need to peel the potatoes?

Peeling ensures a smoother filling, but you can leave the skins on for a more rustic texture if preferred.

Can I make these gluten-free?

Use a gluten-free puff pastry and ensure your vegan cheese and other ingredients are also certified gluten-free.

What’s the best way to seal the edges?

Press the edges with a fork firmly, and don’t overfill to avoid leaks during baking.

Can I air fry these?

Yes, air fry at 375°F (190°C) for 10–12 minutes, checking for golden color and puffiness.

Can I serve them cold?

They’re best served warm, but can also be enjoyed at room temperature as a savory snack.
