How to Make Onion Tarte Tatin

Prepare for baking: Preheat the oven to 350F/180C

Prepare the onions: Peel the papery skins off the onions and cut the onions into wedges from the roots to the stems.

Brown the onions: In an oven-safe skillet, melt the butter over medium heat. Add the onion wedges to the pan and cook for 5 minutes. Flip them occasionally until the edges turn brown.

Caramelize the onions: Add the maple syrup and balsamic vinegar to the pan and cook for an additional 5 minutes to caramelize. Remove from heat.

Assemble the tart: Arrange the onion wedges in a circular pattern at the bottom of the skillet, add thyme, and season with salt and pepper.

Prepare the pastry: Roll out the pastry dough on a floured surface so the dough is slightly larger than the skillet. Carefully place the dough on top of the onions and tuck in the edges. Poke 2 holes at the top to allow steam to escape.

Bake the onion tatin: Bake for 20 minutes in the preheated oven or until the pastry crust is golden brown. Let it cool for 5 minutes.

Flip and serve: Place a heavy plate on top of the skillet and carefully flip the tart onto the plate so the onion side is right-side up. Slice and serve with a garnish of fresh thyme.

Top tips

While the onions are caramelizing, you may need to add a tablespoon of water or two to prevent them from burning.

Make sure you cut all the onion wedges all roughly the same size to ensure they cook evenly together.

Use flour with the puff pastry to ensure everything stays together.

Let the tart cool for 5 minutes to allow the puff pastry to set to prevent it from baking.

Be sure to use a skillet that can transfer from the stovetop to the oven properly.

Variations

You may love the Jamie Oliver tarte tatin, but this version is quick, easy and bursting with flavor.

Add other vegetables to the onions such as sliced apples, chopped roasted Brussels sprouts, or your favorite protein to make it a well-rounded meal.
