Embrace the vibrant flavors of summer’s bounty with this exquisite and crowd-pleasing Cheesy Tomato Tart, generously layered with sweet caramelized onions. This recipe transforms seasonal produce into a sophisticated yet simple dish, perfect for any gathering or a delightful weeknight meal.
There’s an undeniable charm to a classic tomato tart. Its flaky, buttery crust, combined with the refreshing burst of ripe tomatoes and savory cheese, creates a symphony of textures and tastes. It truly embodies the essence of summer dining, offering a light yet satisfying experience. But what if we told you there’s a way to elevate this beloved dish to an entirely new level?
This isn’t just any ordinary tomato tart. We’ve taken a timeless concept and infused it with an irresistible depth of flavor, ensuring every bite is a memorable one.
Beyond the Ordinary: A Flavorful Twist on a Classic
Our rendition starts with a crisp, golden puff pastry base, but what truly sets it apart is the incredibly rich and complex filling. Forget simple goat cheese; this tart boasts a luxurious, flavor-packed blend that will tantalize your taste buds. We combine tangy goat cheese with creamy cream cheese, infusing it with aromatic minced garlic and a generous medley of fresh herbs. But the real star of this decadent spread? An abundance of slow-cooked caramelized onions – so sweet and savory, you might be tempted to grab a chip and enjoy it as a dip all on its own!
The magic begins as these thinly sliced onions are slowly cooked down with a touch of sugar and butter, transforming into a deeply golden, sweet, and unbelievably tender confit. This process, though requiring a bit of patience, is absolutely crucial for developing the rich, umami-laden sweetness that defines this tart. Once perfectly caramelized, fresh garlic, thyme, and rosemary are added, allowing their herbaceous notes to meld with the savory onions, creating an intoxicating aroma and flavor profile that truly sings of summer.
Once cooled slightly, this fragrant herby, garlicky onion mixture is introduced to the bowl containing the softened goat cheese and cream cheese. A few minutes in a stand mixer, and you’ll witness a magical transformation as these ingredients combine into a wonderfully fluffy, rich, and utterly addictive spread. The paddle attachment works its charm, whipping air into the cheese and onion mixture, making it light enough to spread beautifully yet robust enough to hold up to the juicy tomatoes.
The Grand Finale: Heirloom Tomato Perfection
After a generous, luscious layer of the caramelized onion cheese spread is meticulously applied to the prepared puff pastry (a moment of pure culinary bliss!), it’s time for the true stars of the show to make their dazzling appearance: the heirloom tomatoes. These exquisite beauties, with their diverse shapes, sizes, and vibrant hues, are not just visually stunning but also offer a complex, sweet, and tangy flavor unmatched by their conventional counterparts.
Imagine a sweet rainbow medley of heirloom beauties! Each tomato is carefully sliced, then fanned out in an artful pinwheel design atop the creamy cheese base. This meticulous arrangement ensures that every slice delivers a burst of fresh tomato goodness, complementing the rich and savory undertones of the caramelized onion and cheese spread. Once assembled, this “bad boy” is ready for its grand transformation in the oven, where the puff pastry will rise to golden perfection, the cheese will melt into a warm, inviting layer, and the tomatoes will soften just enough to release their incredible flavors.
Upon emerging from the oven, golden brown and gloriously puffed, the tart is a sight to behold. To elevate the experience even further, offer your guests a thick drizzle of tangy balsamic syrup. Its rich, sweet-tart notes provide a perfect counterpoint to the savory tart, adding a sophisticated finish that truly rounds out the flavors.

Tips for Making the Best Cheesy Tomato Tart
- Caramelizing Onions: Patience is key! Cook the onions slowly over medium-low heat. Don’t rush the process, as true caramelization takes time (about 20 minutes) and develops the deep sweetness that makes this tart so special. Stir occasionally to prevent burning.
- Draining Tomatoes: Tomatoes contain a lot of water, which can make your tart soggy. After slicing, arrange them on a paper towel-lined baking sheet and lightly salt them. Let them sit for 15-20 minutes to draw out excess moisture, then gently pat them dry before placing them on the tart. This step is a game-changer for a crisp crust!
- Puff Pastry: Ensure your puff pastry is properly thawed but still cold when working with it. This prevents it from becoming too sticky and makes it easier to handle. Don’t overwork the dough; light handling is best for that flaky texture.
- Room Temperature Cheeses: Allow the goat cheese and cream cheese to come to room temperature before mixing. This ensures a smooth, lump-free cheese spread that’s easy to combine and spread evenly.
- Scoring the Border: Scoring a 1-inch border on the pastry without cutting all the way through creates a beautiful crust that puffs up around the filling, creating a natural edge to hold everything in. Pricking the center (docking) prevents the middle from puffing up excessively.
Variations and Substitutions
- Cheese Choices: While goat cheese and cream cheese offer a unique tang and creaminess, feel free to experiment. Feta cheese can add a saltier, sharper kick, while mascarpone or ricotta could offer an even richer, softer texture. A blend of mozzarella and Parmesan can also be delicious.
- Herb Garden: Don’t limit yourself to thyme and rosemary. Fresh basil, oregano, chives, or even a hint of marjoram would be wonderful additions to the cheese mixture, complementing the tomatoes beautifully.
- Add More Veggies: Thinly sliced zucchini, bell peppers, or even a sprinkle of spinach could be added alongside or instead of some of the tomatoes for extra nutrition and color.
- Crust Alternatives: If puff pastry isn’t your preference, a good quality shortcrust pastry or even a homemade pie crust can work well, though the flakiness will differ.
- Spicy Kick: For those who love a bit of heat, a pinch of red pepper flakes in the caramelized onions or cheese mixture would provide a delightful warmth.
Serving Suggestions for Your Cheesy Tomato Tart
This versatile tart shines in many roles! Serve it warm or at room temperature. As an appetizer, slice it into smaller squares or wedges. For a light lunch or dinner, serve a larger slice alongside a fresh green salad with a simple vinaigrette. It’s also fantastic for brunch spreads, picnics, or potlucks, as it travels well and is enjoyable even when not piping hot.

Cheesy Tomato Tart with Caramelized Onions
Ingredients
- All-purpose flour, for rolling out dough
- 1/2 (17.3-oz.) package frozen puff pastry (1 sheet), thawed
- 4 pounds assorted heirloom tomatoes, thinly sliced and excess moisture patted dry (optional, but recommended for a crisper crust)
- 2 onions, thinly sliced
- 2 Tablespoons unsalted butter
- 1 Tablespoon sugar
- 4 cloves garlic, minced
- 1 Tablespoon minced fresh thyme
- 1 Tablespoon minced fresh rosemary
- 8 oz. goat cheese, at room temperature
- 8 oz. cream cheese, at room temperature
- 2 large eggs
- Balsamic syrup, for topping (optional)
- ½ teaspoon salt
- ¼ teaspoon pepper
Instructions
- Preheat your oven to 425°F (220°C). Prepare a baking sheet by lining it with parchment paper for easy cleanup.
- In a medium saucepan, melt the unsalted butter over medium heat. Add the thinly sliced onions and cook, stirring occasionally, until the butter is fully melted and the onions begin to soften.
- Stir in the sugar and continue to cook the onions over medium-low heat, stirring occasionally, for about 20 minutes, or until they are deeply golden brown and beautifully caramelized. Add the minced garlic, fresh thyme, and fresh rosemary, then cook for another 5 minutes until the garlic is fragrant and lightly golden. Transfer this flavorful mixture to a separate bowl and allow it to cool completely to room temperature. This cooling step is important to prevent the cheese from melting prematurely.
- While the onions cool, prepare the cheese filling. In a stand mixer fitted with a paddle attachment (or using a hand mixer), beat together the softened goat cheese, cream cheese, large eggs, ½ teaspoon of salt, and ¼ teaspoon of pepper until smooth and well combined. Once the caramelized onion mixture is completely cool, add it to the cheese mixture and mix on low speed until just incorporated and fluffy.
- Lightly flour your clean work surface. Carefully unfold the thawed puff pastry sheet. Use a rolling pin to gently roll over the pastry, sealing any creases and slightly expanding it.
- Transfer the puff pastry to your prepared baking sheet. Using a fork, prick the entire center area of the pastry (inside where the filling will go). Then, gently score a 1-inch border around all of the edges of the pastry with a knife, being careful not to cut all the way through the dough. This border will puff up to create a beautiful crust.
- Evenly spread the creamy caramelized onion cheese mixture over the pricked center of the puff pastry, making sure to keep it within the scored border. Carefully arrange the sliced heirloom tomatoes on top of the cheese mixture, overlapping them slightly to create an appealing pinwheel or mosaic pattern.
- Bake the tart in the preheated oven for approximately 25 minutes, or until the pastry is puffed and golden brown, and the cheese filling is set. Remove the tart from the oven and let it cool on the baking sheet for at least 10 minutes before slicing and serving. For an extra touch of gourmet flavor, drizzle with balsamic syrup just before serving (optional).
