This pumpkin tart celebrates every part of the pumpkin—no waste, just cozy autumn goodness! It’s a comforting, earthy dish that perfectly captures why I love cooking with seasonal produce. There’s something so heartwarming about fall pumpkins that just makes the kitchen feel like home.

Normally, pumpkin makes its way into sweet treats (I’m definitely guilty of pumpkin cookies!), but this savory tart flips the script. We keep the skin on the pumpkin—it roasts soft and is totally edible by the end. Plus, the pumpkin seeds get transformed into a crunchy, bright gremolata that adds texture and a fresh pop against the deep, rich flavors of the filling. Layered over a zesty sun-dried tomato and roasted red pepper spread, this tart bakes into a showstopper perfect for cozy get-togethers or a special weeknight dinner.

I could chat about this tart all day, but here’s the scoop: it’s comfort food with good looks, easy enough to make on a relaxed afternoon, and guaranteed to impress. Keep reading for the full step-by-step to bring this fall favorite to life in your kitchen.

Ingredients you’ll need for this pumpkin tart

This recipe has a few parts, but don’t let that scare you. Each ingredient builds on the last to create a flavorful, layered dish that comes together smoothly. Here’s everything you’ll want on hand:

• 2 servings all-butter pie crust, or store-bought puff pastry if you’re looking for a quick shortcut
• 1 medium pumpkin, cored and scooped out
• 2/3 cup pumpkin seeds from the same pumpkin, rinsed and dried—those little crunch-makers!
• 3/4 teaspoon each of coriander, cumin, chili powder, and smoked paprika—these spices bring cozy warmth and depth
• Kosher salt and freshly ground black pepper, to taste
• 1 medium red onion, thinly sliced for caramelizing
• 1/3 cup roasted red peppers, packed in oil
• 1/3 cup sun-dried tomatoes, packed in oil
• 1 teaspoon kosher salt, for seasoning the sun-dried tomato spread
• 1/2 cup cool water, to blend the spread creamy
• 2/3 cup fresh cilantro, stems and leaves included, for the vibrant gremolata
• 1/4 cup fresh mint leaves, adding a fresh, cooling note
• 1 lime, juiced
• 1 egg, for brushing the crust to a golden shine
• 1 tablespoon honey (optional—more on that below)
• Olive oil, for cooking and drizzling throughout

The pie crust for this pumpkin tart

I stick with an all-butter pie crust here because it’s tender, flaky, and the perfect soft-but-crisp backdrop for all the filling flavors. The recipe makes enough dough for two tarts, which works great since we’re using a whole pumpkin. Less waste, more tart!

If you’re short on time or want to keep things super simple, store-bought puff pastry is a fantastic alternative. It won’t have quite the rich butter flavor, but it’s quick, reliable, and tasty enough to satisfy.

How to prepare the pumpkin for this tart

We roast the pumpkin twice, which is the secret to tender skin you can actually eat—it adds so much texture and saves time. Start by slicing the pumpkin into thin half-moon shapes, cutting lengthwise down from top to bottom. Check out the pictures if you want a visual.

Then, toss the pumpkin slices with the spices: coriander, cumin, chili powder, smoked paprika, and a pinch of salt and pepper, plus a light drizzle of olive oil so they roast up beautifully. Lay them out on a baking sheet.

Take your rinsed and dried pumpkin seeds and spread them on a separate baking sheet. Sprinkle them with a bit of kosher salt to boost the flavor.

Bake both sheets in a 375°F oven: the pumpkin slices roast for about 15 minutes, while the seeds toast for 20 to 25 minutes until they turn golden and crunchy.

Once the pumpkin is tender and the seeds are perfectly toasted, you’re ready for the next step. This roasting combo brings the tart’s textures and flavors to life!

The timing for the rest of this pumpkin tart recipe

This recipe moves nicely when you coordinate your steps. Since the pumpkin and seeds roast together, you have plenty of time to get other parts ready in the meantime!

Start caramelizing your red onions next. Thinly slice one medium onion and cook it slowly in about 2 tablespoons of olive oil over medium heat. Sprinkle some salt as it softens. Stir occasionally for 10 to 15 minutes until the onions become jammy, sweet, and golden brown. When done, remove from heat and set aside.

While the onions caramelize, blend your roasted red peppers and sun-dried tomatoes with some water, a tablespoon of oil from the sun-dried tomato jar (it’s packed with flavor!), and a pinch of salt. Blend until smooth and spreadable. Add more water for a thinner consistency if you like.

Once the pumpkin seeds come out of the oven, chop them by hand or pulse a few times in a food processor to keep a bit of crunch. Chop the cilantro and mint, then toss everything together with a squeeze of lime juice, a drizzle of olive oil, and salt to taste. This gremolata is bright, fresh, and has the perfect crunch to contrast the soft pumpkin and onions.

If you time it right, everything will finish just about the same time, so you can assemble your tart right away.

Bringing this recipe together

Now let’s put it all together! Roll out your chilled pie crust on a baking sheet or tart pan, leaving about 2 inches of space around the edges.

Spread a generous layer of the sun-dried tomato and roasted red pepper blend evenly over the crust base. Next, layer the roasted pumpkin slices and caramelized onions, overlapping them so the tart looks full and inviting.

Carefully fold the edges of the crust up and around the filling—that rustic look is part of the charm! Chill your tart in the fridge for at least 15 minutes. This step helps the crust keep its shape and bake up nicely.

If you made two tarts, chill both so they’re ready to go. Or you can store the fillings separately and assemble just before baking if that fits your schedule better.

Right before baking, whisk an egg to create a shiny egg wash. Brush it over the exposed crust edges to get a gorgeous golden finish.

Bake in a 375°F oven for 40 to 45 minutes, or until the crust turns deep golden and the filling bubbles gently.

If you love a sweet-and-savory touch, mix a tablespoon of honey with a little olive oil and brush it over the tart as soon as it comes out of the oven. This adds a lovely glossy shine and balances the savory flavors with a hint of sweetness.

Finally, sprinkle the fresh cilantro and pumpkin seed gremolata over the top. Serve your tart warm and get ready for all the compliments!

And that’s your Pumpkin Tart with Caramelized Onions and Pumpkin Seed Gremolata! It’s a tasty, beautiful dish that’s easier to pull off than you might think—and totally worth it.

Storage Tips

After you enjoy your tart, wrap any leftovers tightly with plastic wrap or store in an airtight container in the fridge. It should keep well for up to 3 days. When you want more, reheat individual slices in the oven at 350°F for about 10 minutes to crisp the crust back up, or microwave for a quick warm-up, though the crust won’t stay quite as crisp.

Make-Ahead Tips

You can easily prepare parts of this tart a day or two ahead. Roast the pumpkin and pumpkin seeds in advance, even caramelize the onions and make the sun-dried tomato spread. Store each component separately in the fridge, then assemble and bake right before serving. This breaks up the work and makes the whole process feel much more manageable on busy days.

Variations

Want to switch things up? Try swapping the pumpkin for butternut squash or sweet potatoes for a similar sweet, earthy flavor. If you don’t have fresh herbs, pesto or chopped parsley can make a tasty gremolata substitute. For added creaminess, dollop some ricotta or goat cheese over the filling before baking.

Serving Suggestions

This tart stands beautifully on its own as a light main course paired with a simple green salad dressed with lemon and olive oil. For a heartier meal, serve alongside roasted chicken or pork. It also pairs nicely with a warm bowl of soup on chilly days, making it a versatile addition to your fall menu.

Recipe FAQs

• Can I use canned pumpkin instead of fresh? Fresh pumpkin really makes the difference here because we roast the skin on and create those tender slices. Canned pumpkin is pureed and won’t work the same way for this tart.
• What if I don’t want to use an egg wash? You can skip it, but your crust won’t have that glossy golden finish. For a vegan option, brushing with a little olive oil or plant milk can help the edges brown nicely.
• How spicy is the tart? The spices add warmth but aren’t hot or overpowering. If you prefer, adjust the chili powder amount to your taste.
• Can I make this gluten-free? Absolutely! Use your favorite gluten-free pie crust or puff pastry for a delicious allergy-friendly version.:
