Alternative Ingredient Suggestions
If you’re looking for substitutions or need to accommodate dietary preferences, here are some ideas:
- Butternut squash alternatives: Sweet potato or pumpkin can also be used if you prefer a different root vegetable.
- Dairy-free option: Swap the ricotta with a dairy-free cheese, such as a vegan cream cheese alternative.
- For added crunch: Consider adding a sprinkle of chopped nuts, like pecans or walnuts, for texture and flavor contrast.
Step-by-Step Instructions
1. Caramelize the Onions
Start by heating a cast iron skillet over medium heat. Add one tablespoon of olive oil and one tablespoon of butter, allowing the butter to melt and foam. Add the thinly sliced sweet onion and a pinch of salt. Stir occasionally, letting the onions cook slowly for about 25–30 minutes until they turn golden brown. When the onions are caramelized, deglaze the pan with a splash of balsamic vinegar, then stir in the fresh sage and cook for another minute. Set aside.
2. Roast the Butternut Squash
Peel, seed, and dice the butternut squash into ½-inch cubes. Toss the cubes with the remaining tablespoon of olive oil and a pinch of salt and pepper. Spread them on a baking sheet and roast in a preheated oven at 400°F for 15-17 minutes, or until the squash is golden brown and tender.
3. Prepare the Puff Pastry
While the squash and onions are cooking, prepare the puff pastry. Roll out the pastry on a floured surface, being careful not to tear it. Cut the pastry into 16 even squares. Place the squares on a parchment-lined baking sheet, leaving a little space between each square. Score the edges with a knife and dock the centers with a fork to prevent puffing in the middle. Brush each square with egg wash.
4. Assemble the Tarts
Place a teaspoon of ricotta cheese in the center of each puff pastry square. Top with a slice or two of caramelized onions and a tablespoon of roasted butternut squash cubes. Gently press the filling into the pastry but be careful not to let it overflow. Chill the prepared tarts in the fridge for at least 15 minutes or up to 24 hours to ensure they puff up properly during baking.
5. Bake the Tarts
Preheat your oven to 400°F. Bake the tarts for 12-14 minutes, or until the pastry is golden and puffed. Once baked, sprinkle with fresh sage for an added touch of flavor. Serve warm or at room temperature.

Tips & Tricks
- Do not overfill: When adding the filling, keep it to a moderate amount. Overfilling the puff pastry squares can cause them to spill over and not puff properly.
- Chill before baking: Letting the tarts chill before baking ensures they maintain their shape and puff up beautifully.
- Storage: If you have leftovers, store them in an airtight container for up to two days. They can be reheated in the oven for a few minutes to restore the crispness of the puff pastry.
Pairing Ideas and Variations
These mini butternut squash tarts pair wonderfully with a fresh salad or roasted vegetables. They can also be served with a dipping sauce, like a tangy mustard vinaigrette or a rich balsamic glaze. For those who love a bit of spice, try adding a sprinkle of red pepper flakes or a dash of cayenne pepper to the filling.
For variations, you can experiment with adding different cheeses, such as goat cheese or Gruyère, or incorporate other herbs like thyme or rosemary for a unique twist.
