How to make Sweet Potato, Gruyere, & White Cheddar Puff Pastry Tart
- Preheat oven to 425°F. Add butternut squash to a large baking sheet and toss with 1 tbsp oil, ½-1 tsp kosher salt, and few turns of black pepper. Roast for 25-30 minutes until soft. Reduce oven temp to 375°F.
- Add remaining 1 tbsp olive oil to a large skillet over medium-high heat. Add shallots and a pinch of kosher salt. Saute for 4-5 minutes until soft then add garlic and thyme. Cook for 1 additional minute. Add in baked sweet potato, balsamic, tamari, and ½ tsp kosher salt and mix well to combine. Transfer mixture to a bowl and let cool for 10-15 minutes.
- Remove puff pastry from fridge. Score top layers of puff pastry along all 4 sides of the dough (leaving 1-inch border). Transfer the pastry to a parchment-lined large baking sheet. Prick the dough with a fork all over (only the center, not the edges).
- Sprinkle the cheese over the dough. Top with cooled sweet potato mixture. Lightly beat egg with 1 tsp water in a small bowl to create an egg wash. Brush the edges of the tart with egg wash. Bake the tart for about 20-25 minutes or until golden.
- Serve warm tart with additional fresh thyme, freshly cracked black pepper, and optionally drizzle of hot honey.


Modifications + Serving Suggestions:
Substitute tamari with low-sodium or regular soy sauce.
Substitute gruyere and white cheddar cheese with your favorite cheeses, such as feta, mozzarella, or parmesan.
Make this recipe vegan…
- Substitute cheese for your favorite vegan shredded cheese
- Make sure to buy a vegan puff pastry shell (which most brands are naturally vegan!)
- Brush shell with non-dairy milk instead of egg wash
I love topping this puff pastry tart with more fresh thyme, drizzle of hot honey, and cracked black pepper.

Puff pastry tarts are best eaten right away or day-of. Store in an airtight container, refrigerate, and enjoy within 1-2 days.
To reheat, add to a 350F oven and heat for 5-10 minutes until crisp and warm.
