Crisp layers meet tangy toppings in a simple bake that brightens any gathering.

Upside-Down Puff Pastry Radish Tarts

Upside-down puff pastry radish tarts are a stunning, quick, and easy appetizer that brings together crisp, golden puff pastry, creamy cheese, and the subtle sweetness and color of fresh radishes. Inspired by the viral TikTok trend for upside-down tarts, these savory pastries use simple store-bought ingredients to deliver maximum impact with minimal effort. Whether served as a brunch centerpiece, an elegant appetizer, or a delightful snack, these tarts highlight how simple techniques and colorful produce can elevate everyday baking.

Perfect for entertaining or enjoying at home, this recipe also invites flexible substitutions and creative variations for any cook’s repertoire.

Why Upside-Down Tarts Are Trending

The upside-down tart trend took off across social media because it reinvents classic tart-making with a clever twist. Rather than placing toppings on top of a pastry base, the ingredients are arranged directly on parchment, then covered with puff pastry. After baking, the tarts are flipped to reveal a beautifully caramelized, patterned topping—no soggy crusts or complicated assembly required.

Effortless technique: Laying toppings underneath eliminates the need to pre-bake tart shells or worry about wet fillings.
Creative inspiration: Viral versions feature both sweet and savory combinations—from apples and cinnamon to onions, tomatoes, and root vegetables.
Visually stunning: Upside-down assembly produces an appealing, glossy finish and showcases the natural colors of the main ingredient.

What Makes These Radish Tarts Special?

This recipe stands out among viral tarts by spotlighting radishes, a vegetable often underused outside salads. Their vibrant shades and gentle flavor are accentuated by a simple sweet-and-sour dressing, creamy cheese, and the crisp flakiness of puff pastry.

Radishes: Thin slices soften and mellow in the oven, gaining a hint of sweetness.
Gournay cheese: Rich, herbed cheese (like Boursin) brings savory creaminess that balances the tangy radishes.
Caramelized base: Baking upside-down ensures that the toppings merge seamlessly, and the pastry stays golden without getting soggy.

As with many Tiktok trends, there’s plenty of room for creativity—this concept works equally well with carrots, beets, onions, or even fruit.

Ingredients for Upside-Down Puff Pastry Radish Tarts

Ingredient	Amount
Olive oil	2 Tbsp.
Red wine vinegar	1 Tbsp.
Honey	1 tsp.
Kosher salt	1/2 tsp.
Ground black pepper	1/4 tsp.
Radishes, trimmed, thinly sliced (1/8-inch)	12 (medium)
Puff pastry, thawed	1 (17.3 oz.) package
Shallot and chive gournay cheese	1 (5.2 oz.) container
Large egg, lightly beaten	1
Fresh chives, chopped (for garnish)	To taste

Ingredient Notes:

Use multicolored radishes or swap in colorful carrots for a different look and taste.
Gournay cheese (like Boursin) can be replaced with any creamy spreadable cheese flavored with herbs and onions.
Pre-made puff pastry from the freezer section saves time and ensures flaky results.

Step-by-Step Directions

Preheat the oven to 400°F. Arrange oven racks in the upper and lower thirds. Line two baking sheets with parchment paper.
Make the radish marinade: In a medium bowl, mix olive oil, red wine vinegar, honey, salt, and pepper. Add radish slices and toss to coat evenly.
Prepare the puff pastry: Unfold puff pastry sheets; cut along the folds to create 3 long columns. Cut each column in half to form 6 (4-by-3-inch) rectangles per sheet, totaling 12 rectangles. Evenly spread gournay cheese on each rectangle, leaving a 1/2-inch border.
Arrange the radishes: On the prepared baking sheets, shingle about 16 radish slices into a compact (3-by-2-inch) rectangle for each tart. (You should have 6 per sheet.)
Assemble tarts: Place cheese-covered pastry rectangles (cheese facing radishes) on top of radish arrangements. Gently crimp the pastry edges over the radishes using a fork. Brush pastry with beaten egg.
Bake: Bake for 25 to 30 minutes, until golden brown and puffed. At the 20-minute mark, swap pans from top rack to bottom and vice versa for even baking.
Finish: Let pastries cool for 5 minutes. Flip each tart upside-down using a spatula to reveal the caramelized radish layer. Transfer to a wire rack.
Serve: Enjoy warm or at room temperature. Drizzle with any reserved vinegar mixture and sprinkle chopped chives as garnish.

Tips for Success

Slice radishes thinly: Consistent, even slices guarantee even cooking and artistic presentation.
Don’t overfill: Restrain from overloading with cheese or radishes so pastries seal properly and bake up crisp.
Serve promptly: Tarts are at their best shortly after baking when pastry is crispy and radish color is at its brightest.
Day-ahead tip: Baking these tarts in advance is not recommended; prepare and bake shortly before serving for optimal results.

Serving Ideas & Variations

These versatile tarts can be enjoyed as:

Appetizers at parties or potlucks, arranged on a platter with extra herbs.
Snack or breakfast, paired with coffee or a refreshing cocktail.
Side dish for brunch, served alongside seasonal salads or poached eggs.

Creative Variations:

Swap radishes for thinly sliced carrots, beets, zucchini, or onions for different flavors and colors.
Use flavored cream cheese, ricotta, or herbed goat cheese instead of gournay cheese.
Top with microgreens, toasted seeds, or a drizzle of balsamic glaze for extra flair.

Why This Technique Works

Upside-down assembly creates several advantages:

No soggy crust: Filling sits on top of parchment, below the pastry, so excess moisture doesn’t soak into the puff pastry.
Caramelization: Direct contact with the pan and a touch of honey encourages gentle browning and flavor development in the radishes.
Easy release: Once baked, the tarts flip out neatly and display the arranged vegetables on top—no sticking or tearing.

This method is especially effective for baked goods with fresh produce that could otherwise turn the crust soggy before it crisps up.

Beyond Radish: Upside-Down Tart Inspirations

These tarts are just the beginning! The upside-down method works beautifully with both sweet and savory flavors. For a brunch spread or party tray, try:

Sliced apples or pears tossed with cinnamon and sugar for a quick upside-down fruit tart.
Heirloom tomatoes and shallots with pesto and mozzarella for a Mediterranean twist.
Root vegetables like carrots or beets marinated with olive oil, thyme, and honey for an earthy, colorful alternative.
Sweet onion, caramelized on the base and topped with cheese for a French-inspired tarte tatin.

Substitute toppings and cheeses to complement the season or your favorite produce.

Frequently Asked Questions (FAQs)

Can I make the tarts ahead of time?

For best results, prepare and bake the tarts just before serving. The radish color and puff pastry crispness diminish if stored, so bake within a few hours of serving for maximum appeal.

What kind of cheese can I use if I don’t have gournay?

Any creamy, spreadable cheese works—herbed goat cheese, flavored cream cheese, or even a thick ricotta blend can substitute for gournay cheese.

Can I use different vegetables in this recipe?

Absolutely! Thinly sliced carrots, beets, zucchini, or onions are all delicious alternatives. Just ensure the vegetables are cut thin for even cooking and caramelization.

How do I get neat, thin radish slices?

Use a sharp chef’s knife or a mandoline slicer for consistent, even slices. This helps the radishes cook evenly and look beautiful when revealed on top of the tart.

Will the radishes taste spicy once baked?

No, baking mellows the sharp bite of radishes, leaving a mild, gently sweet flavor that pairs nicely with the savory cheese and pastry.

Expert Tips for Upside-Down Tart Success

For an extra-glossy finish, mix a touch of honey into the reserved marinade and drizzle on the tarts just before serving.
If using other root vegetables, blanch firmer ones (e.g., carrots) briefly before assembling to ensure tenderness.
Let the tarts cool for 5–10 minutes before flipping to minimize breaking and help fillings set.
Garnish with fresh herbs like chives, dill, or tarragon for added color and aroma.
