Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

3 medium red onions (about 600 g), peeled and cut into wedges
50 g unsalted butter (1/4 cup)
2 tablespoons honey
2 tablespoons balsamic vinegar
3 to 4 fresh thyme sprigs, leaves only
200 g fresh goat cheese, sliced into rounds (7 ounces)
1/2 teaspoon salt
1/4 teaspoon freshly ground black pepper
250 g ready-rolled puff pastry (9 ounces)

Directions

Preheat your oven to 180°C (350°F).

Cut the red onions into wedges from root to stem so they hold their shape while cooking.

In a 23 cm (9-inch) ovenproof skillet, preferably cast iron, melt the butter over medium heat. Add the onion wedges in a single layer and cook for about 5 minutes, turning gently until they begin to soften and lightly brown.

Drizzle the honey and balsamic vinegar over the onions. Continue cooking for another 5 minutes, gently shaking the pan occasionally to prevent sticking. The onions should become glossy and caramelized.

Arrange the onions neatly in the skillet, placing them cut-side down to create an attractive pattern for when the tart is inverted. Sprinkle with thyme leaves, salt, and black pepper.

Remove the skillet from heat and let it cool slightly. Arrange the sliced goat cheese evenly over the onions.

Roll out the puff pastry into a circle slightly larger than the skillet. Carefully place it over the onions and cheese, tucking the edges down along the inside rim of the pan. Cut two small slits in the center to allow steam to escape.

Bake for 20 to 25 minutes, or until the pastry is puffed and golden brown.

Remove from the oven and let rest for 5 minutes. Place a large serving plate over the skillet and carefully invert the tart. Lift off the skillet gently. Serve warm or slightly lukewarm.

Variations

You can easily customize this savory tart to suit your taste:

Add chopped walnuts or pecans before placing the pastry on top for added crunch.

Sprinkle a handful of fresh arugula over the tart just before serving for a peppery contrast.

Replace goat cheese with feta for a saltier profile.

Add thin slices of pear for a sweet and savory variation.

Incorporate a teaspoon of fresh rosemary instead of thyme for a deeper herbal note.

Use a homemade pie crust instead of puff pastry for a sturdier base.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days.

To reheat, place slices in a preheated oven at 170°C (340°F) for about 8 to 10 minutes until warmed through. This helps maintain the crispness of the pastry. Avoid microwaving if possible, as it can make the pastry soft.

You can also enjoy the tart at room temperature.

Freezing is not recommended, as the texture of the onions and pastry may become soggy upon thawing.

FAQs

Can I make this tarte tatin ahead of time?

Yes. You can prepare and bake it a few hours in advance. Reheat gently in the oven before serving for best results.

What if I do not have a cast iron skillet?

You can cook the onions in a regular pan and then transfer them to a round baking dish before adding the cheese and pastry.

Can I use white or yellow onions instead of red onions?

Yes, but red onions provide a sweeter and more vibrant result once caramelized.

How do I prevent the tart from sticking?

Ensure the skillet is well coated with butter and allow the tart to rest briefly before inverting.

Is it necessary to cut slits in the pastry?

Yes, small slits allow steam to escape and prevent the pastry from puffing unevenly.

Can I make this recipe gluten-free?

Yes, simply use a gluten-free puff pastry alternative.

What can I serve with this tart?

A simple green salad with a light vinaigrette pairs beautifully with the richness of the tart.

Can I reduce the sweetness?

You can slightly reduce the honey or add a touch more balsamic vinegar to balance the flavor.

How do I know when it is fully baked?

The pastry should be golden brown and fully puffed. The bottom should feel crisp when gently tapped.

Can I serve this cold?

It is best served warm or at room temperature, but it can be eaten cold if desired.
