How to Make Onion Tarte Tatin
Wondering how to make this Onion Tarte Tatin recipe? It's easy! Just follow this step-by-step photo tutorial. Then, scroll down for the recipe card for the full ingredients list and recipe method.
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.
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.
Serve a slice for lunch with a warm bowl of Lentil Soup.
Makes a great presentation for a dinner party along with Stuffed Butternut Squash.
Pair it with a Green Salad for a well-rounded lunch or dinner. Or add a Red Kuri Salad or Rocca Salad.
Serve small slices on a Breakfast Charcuterie Platter for breakfast or brunch.
Add different types of onions, such as red onions or Vidalia onions.
Change up the herbs by adding in other herbs, like rosemary or sage.
Throw in some of your favorite melty cheese such as swiss, gorgonzola, gouda, or gruyere to add a layer of cheesy flavor.
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.
Storing: Store in an airtight container for up to three days.
Freezing: Separate the tart into individual servings and wrap them tightly with plastic wrap before freezing for up to 3 months. Let it thaw overnight or at room temperature for a few hours (if frozen) until ready to use.
Yes, you can make it a day in advance. Just store it in an airtight container and reheat it before serving.
You can cook the onions in a skillet, then add them to a pie plate and add the puff pastry on top before baking.
Many people prefer to eat it warm, but it can be served cold or at room temperature if desired.
