Ingredients You’ll Need
The beauty of this Sweet Potato, Feta & Caramelized Onion Tart Recipe lies in its simplicity. Every ingredient plays a crucial role—from the flaky puff pastry that creates the perfect base, to the sweet potatoes that bring a lovely earthiness, and the caramelized onions that add depth and richness. Here’s what you’ll need:
- Puff pastry sheet: This flaky, buttery base is essential for that crisp, golden tart crust you’ll love.
- Sweet potatoes: They add natural sweetness and a tender bite when roasted.
- Olive oil: Used to toss the sweet potatoes, it helps to achieve that beautiful roasted exterior.
- Salt and black pepper: Simple but vital for seasoning and enhancing all the flavors.
- Large onion: Thinly sliced onions caramelize into a sweet, silky topping that rounds out the tart.
- Butter: Adds richness to the caramelized onions and contributes to their luscious texture.

- Feta cheese: Crumbled over the top, this adds a tangy, salty punch that contrasts beautifully with the sweet potatoes.

- Egg (for egg wash): Brushed over the pastry edges to achieve a glossy, golden finish.
How to Make Sweet Potato, Feta & Caramelized Onion Tart Recipe
Step 1: Prepare and Roast the Sweet Potatoes
Start by preheating your oven to 400°F (200°C) and lining a baking sheet with parchment paper to keep things clean and easy. Peel and slice the sweet potatoes thinly to ensure they roast evenly and become tender in a shorter time. Toss them in olive oil, salt, and pepper for flavor, then spread them out on the baking sheet. Roast for about 20 minutes until they are soft but still hold their shape. This roasting step intensifies their natural sweetness and lends a lovely slightly crisp edge that’s just irresistible.
Step 2: Caramelize the Onions
While the sweet potatoes roast, focus on those onions. Use a skillet over medium heat to melt butter and slowly cook the thinly sliced onions until they soften. Add the brown sugar partway through to coax out their natural sweetness and help them turn a gorgeous golden brown. This process can take around 15 minutes, but trust me, the deep, rich flavor of caramelized onion is well worth the patience. Set them aside once done.
Step 3: Prepare the Puff Pastry Base
On a lightly floured surface, gently roll out the puff pastry sheet to smooth out any creases and create an even layer. Transfer it carefully onto your lined baking sheet. Using a knife, score a 1-inch border around the edges; this will help the center stay beautifully filled while the edges puff up and crisp perfectly—just be careful not to cut all the way through the dough.
Step 4: Assemble the Tart
Spread those golden caramelized onions evenly inside the scored border—this layer will infuse every bite with a subtle sweetness and rich texture. Next, neatly arrange the roasted sweet potato slices on top. Finally, sprinkle the crumbled feta cheese all across, followed by fresh thyme leaves for that extra pop of aroma and earthiness. These layers combine to create a symphony of flavors that are both rustic and refined.
Step 5: Bake Until Golden
Brush the beaten egg along the edges of the pastry to create a shiny, golden crust as it bakes. Pop the tart into your oven and bake for 20 to 25 minutes. You’ll want to see the puff pastry puff up proudly and turn a beautiful golden brown all over. Once baked, let the tart cool slightly—this makes it easier to slice and helps all the flavors settle together beautifully.
How to Serve Sweet Potato, Feta & Caramelized Onion Tart Recipe
Garnishes
To elevate this tart even more, consider garnishing with a bit of fresh thyme or some chopped parsley just before serving. A gentle drizzle of good-quality extra virgin olive oil can add a subtle brightness, or if you like a hint of heat, a light sprinkle of crushed red pepper flakes can work wonders. These simple touches brighten the dish and allow each flavor to shine.
Side Dishes
This tart pairs wonderfully with vibrant, fresh salads to balance its richness—think a crisp arugula salad with lemon vinaigrette or even a tangy beet and goat cheese salad. Alternatively, roasted vegetables or a simple bowl of seasonal soup make comforting companions, making a meal that feels complete and satisfying without overwhelming the tart’s star ingredients.
Creative Ways to Present
For brunch or a party, try cutting the tart into smaller squares or even bite-sized pieces to serve as savory appetizers. You can also customize the tart by adding roasted nuts like walnuts or pecans for a delightful crunch, or experiment with different fresh herbs depending on what you have on hand. No matter how you present it, the Sweet Potato, Feta & Caramelized Onion Tart Recipe is sure to impress.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers (though they rarely last long), store the tart in an airtight container in the refrigerator for up to 3 days. The flavors deepen over time, making the tart even more delicious the next day. Simply cover it well to keep the pastry from drying out.
Freezing
This tart freezes beautifully if you want to prepare it in advance or save some for a later treat. Wrap it tightly in plastic wrap and then foil, or use a freezer-safe container for up to 2 months. When you’re ready to enjoy, thaw it overnight in the fridge before reheating.
Reheating
To revive the crispness of the pastry and warm the filling, reheat your tart in a preheated oven at 350°F (175°C) for 10-15 minutes. Avoid the microwave if possible, as it tends to make the crust soggy. This way, you get a perfectly warm, flaky, and scrumptious tart every time.
FAQs
Can I use a different type of cheese instead of feta?
Absolutely! While feta’s tanginess complements the sweet potatoes beautifully, you can try goat cheese for a creamy, slightly tart flavor or ricotta for a milder, richer texture. Just remember that feta also adds saltiness, so you might want to adjust seasoning accordingly.
Is puff pastry the only option for the base?
Puff pastry works best for its buttery, flaky layers, but if you prefer, you could use shortcrust pastry for a more crumbly texture or even a homemade pastry dough. Each will change the texture slightly but will still be delicious.
Can I make this tart vegan?
Yes! Substitute the butter with a plant-based alternative, omit the egg wash or replace it with a plant-based milk wash, and swap the feta for a vegan cheese option or seasoned tofu for a similar salty bite.
How thin should the sweet potato slices be?
A thickness of about 1/8 inch is ideal—it helps them roast evenly and become tender without turning mushy. Using a mandoline slicer makes this quick and easy.
Can I prepare the caramelized onions ahead of time?
Definitely! Caramelized onions hold up well and can be stored refrigerated for up to a week. Preparing them ahead saves time on busy days and enhances their flavor as they develop more depth in the fridge.
