- Light brown sugar: Helps in achieving that rich caramelized flavor on the onions.

How to Make Feta and Caramelized Onion Tarts Recipe
Step 1: Prepare the Tart Crust
Start by mixing the flour, salt, and sugar in a large bowl. Add the cold butter cubes and use your fingertips to rub the butter into the flour until it resembles coarse crumbs. Gradually add ice water, one tablespoon at a time, until the dough just comes together. Avoid overworking it—that’s the secret to a flaky crust. Wrap your dough in plastic and pop it into the fridge for at least 30 minutes to rest.
Step 2: Caramelize the Onions
While the dough chills, heat olive oil in a large pan over medium heat. Toss in the sliced red onions and cook slowly, stirring occasionally, for about 30 minutes until they become soft and golden brown. Sprinkle in the brown sugar, drizzle the honey and balsamic vinegar, then season with salt and pepper. Keep cooking for 5 more minutes to let all those flavors meld into a luscious, sticky onion mixture.
Step 3: Prepare the Filling
In a bowl, combine the crumbled feta cheese and softened cream cheese, mixing until smooth. Beat in the egg and chopped parsley. This creamy filling will contrast beautifully with the sweet onions and flaky crust.
Step 4: Assemble the Tarts
Preheat your oven to 375°F (190°C). Roll out the chilled dough on a floured surface to about 1/4 inch thick. Cut into squares or circles depending on your preference and press them gently into tart pans or on a baking sheet lined with parchment paper. Spoon the caramelized onion mixture onto the crusts, then dollop the cheese mixture evenly over the top.
Step 5: Bake to Golden Perfection
Bake the tarts for 25 to 30 minutes until the crust is golden and the filling is set and lightly browned on top. Let the tarts cool slightly before serving to allow the flavors to settle beautifully.

Garnishes
Fresh herbs like parsley or thyme sprinkled on top add that final pop of color and freshness. You can also finish with a drizzle of balsamic glaze for an extra touch of sweetness and a glossy finish that makes these tarts look like they belong in a fancy bistro.
Side Dishes
These tarts shine alongside a crisp green salad dressed simply with lemon and olive oil or a bowl of roasted vegetables. The light salad pairs perfectly with the richness of feta and cream cheese, creating a well-rounded meal.
Creative Ways to Present
Turn these tarts into impressive appetizers by making mini versions in a muffin tin. Alternatively, serve them as individual portions on rustic wooden boards with a selection of olives, nuts, and fresh fruit for a vibrant and inviting spread that’s perfect for sharing.
Make Ahead and Storage
Storing Leftovers
Leftover tarts can be stored in an airtight container in the refrigerator for up to 3 days. Keeping them chilled helps maintain the crisp crust and fresh flavor.
Freezing
Want to prep ahead? Wrap the baked tarts individually in plastic wrap and then foil before freezing. They’ll keep well for up to 2 months. Just be sure to thaw them overnight in the refrigerator before reheating.
Reheating
For best results, reheat your tarts in a preheated oven at 350°F (175°C) for about 10-15 minutes until warm and crisp again. Avoid the microwave if you want to keep that flaky crust intact.
FAQs
Can I use store-bought pie crust for this recipe?
Absolutely! Using store-bought crust is a great shortcut and will still give you delicious results, especially if you’re short on time. Just make sure to thaw it properly before rolling and assembling.
What type of onions works best for caramelizing?
Red onions are preferred for their natural sweetness and beautiful color, but yellow onions work great too if that’s what you have on hand. The key is to cook them low and slow to develop that rich caramelized flavor.
Is it possible to make these tarts vegan?
You can easily swap the feta and cream cheese for plant-based alternatives, and use vegan butter or coconut oil for the crust. The flavor and texture will be slightly different but still delicious!
Can I prepare the caramelized onions ahead of time?
Yes, caramelized onions can be made days in advance and stored in the refrigerator. This actually helps deepen their flavor, so it’s a great step to prep ahead.
What wine pairs well with Feta and Caramelized Onion Tarts Recipe?
Try a crisp, dry white wine like Sauvignon Blanc or a light red like Pinot Noir. These wines complement the tangy feta and sweet onions without overpowering the dish.

- Total Time: 1 hour 15 minutes
- Yield: 8-10 small tarts
Ingredients
For the crust:
- 1¾ cups all-purpose flour
- ½ cup butter, cold and cubed
- 1 teaspoon salt
- 1 teaspoon sugar
- 3–6 tablespoons ice water
For the filling:
- 1 tablespoon olive oil
- 6 medium red onions, sliced
- 1 tablespoon balsamic vinegar
- 3 tablespoons light brown sugar
- 1 tablespoon honey
- Salt and pepper, to taste
- 6 ounces feta cheese, crumbled
- 2 ounces cream cheese, softened
- 1 egg
- 2 tablespoons fresh parsley, chopped
Instructions
- Prepare the crust: In a large bowl, combine the all-purpose flour, salt, and sugar. Cut in the cold, cubed butter using a pastry cutter or fingers until the mixture resembles coarse crumbs. Gradually add the ice water, one tablespoon at a time, mixing until the dough just comes together. Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes to chill.
- Caramelize the onions: Heat the olive oil in a large skillet over medium-low heat. Add the sliced red onions and cook slowly, stirring frequently, until they become soft and golden brown, about 25-30 minutes. Add the balsamic vinegar, light brown sugar, and honey, stirring well to coat. Continue to cook for another 5 minutes until the mixture is thick and sticky. Season with salt and pepper to taste, then remove from heat and let cool completely.
- Make the filling: In a mixing bowl, beat together the feta cheese, cream cheese, and egg until smooth and well combined. Stir in the chopped fresh parsley.
- Assemble the tarts: Preheat the oven to 375°F (190°C). Remove the chilled dough from the refrigerator and roll out on a lightly floured surface to about 1/8 inch thickness. Cut into small rounds or squares to fit your tart pans or a baking sheet. Place the dough pieces on parchment-lined baking sheets or tart pans. Spread a layer of the caramelized onion mixture evenly onto each piece of dough, then spoon the cheese mixture over the top.
- Bake: Bake the tarts in the preheated oven for 20-25 minutes, or until the crust is golden and the filling is set and slightly browned on top.
- Serve: Remove from the oven and allow to cool slightly. Garnish with extra fresh parsley if desired, and serve warm or at room temperature.
Notes
- For a crispier crust, chill the dough thoroughly before rolling out and baking.
- If you prefer a milder onion flavor, use yellow onions instead of red.
- The tarts can be made in advance and reheated gently in the oven before serving.
- These tarts pair well with a light green salad and a crisp white wine.
