Caramelized Onion & Goat Cheese Phyllo Tartlets

These Caramelized Onion and Goat Cheese Phyllo Tartelettes combine sweet, deeply caramelized onions with a tangy, creamy goat cheese filling, all nestled in crisp phyllo cups. They’re elegant, crunchy, and perfect as an appetizer for parties, brunches, or casual gatherings.

If you love the contrast of sweet caramelized onions and tangy goat cheese, these bite-sized tarts are an excellent choice. The flaky phyllo adds crunch and visual appeal, while the filling remains rich and smooth.

How to Make Them

The tartlet shells are made from phyllo dough, which browns into delicate, crisp cups. Phyllo’s texture is a perfect foil for the creamy goat cheese and soft caramelized onions. The method is straightforward: slowly caramelize the onions until they are deep golden and sweet, prepare a simple goat cheese custard, form the phyllo cups, assemble, and bake until set.

Ingredients Overview:

• Phyllo dough (sheets)
• Unsalted butter
• Extra-virgin olive oil
• Onions, diced
• Sugar
• Salt
• Goat cheese
• Dried thyme leaves
• Large eggs
• Heavy cream

Steps Overview:

1. In a wide, heavy-bottomed skillet, heat 2 tablespoons of butter and 1 tablespoon of olive oil over medium-high heat.
2. Add the diced onions and stir to coat them evenly. Cook, stirring frequently so they brown uniformly. When the onions begin to brown, add the sugar and salt, then reduce heat to medium-low.
3. Continue cooking the onions for about 15–20 minutes until they are deeply caramelized and richly colored. Remove from heat and let cool.
4. In a medium bowl, combine goat cheese, eggs, heavy cream, and thyme. Mix with a wooden spoon until smooth and combined.
5. Transfer the goat cheese mixture to a piping bag or a plastic bag with the corner snipped off for easier filling.
6. Preheat the oven to 350°F (175°C).
7. Melt 3–4 tablespoons of unsalted butter. Place one sheet of phyllo on a work surface, brush lightly with melted butter, lay a second sheet on top, brush again, and cut into 12 equal rectangles.
8. Press the phyllo pieces into the cups of a mini muffin tin to form shells. Brush any exposed edges with a little more butter for even browning.
9. Distribute the cooled caramelized onions among the phyllo cups, filling each about halfway.
10. Pipe the goat cheese custard over the onions, filling cups nearly to the top.
11. Bake until the filling is set and just lightly golden, about 16–18 minutes.
12. Allow the tartlets to cool a few minutes, then remove from the muffin tin and serve warm or at room temperature.

Serving Suggestions

Serve these tartelettes warm or at room temperature as part of an appetizer spread. They pair well with fresh greens, a selection of olives, or simple roasted nuts. Because the phyllo is crisp, serve shortly after baking for the best texture.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to five days. To reheat, place tartlets on a baking sheet in a low-temperature oven until the filling is warmed through and the phyllo is crisp again.
