Ingredients
- 3 yellow onions peeled (or 4-5 small onions)
- 3 tablespoons butter or vegan butter
- 2 tablespoons maple syrup or honey
- 2 tablespoons balsamic vinegar
- 3 pieces fresh thyme sprigs plus more for garnish
- 9 ounces (250g) puff pastry thawed if frozen
- 1 tablespoon flour for rolling
- ⅛ teaspoon salt to taste
- ⅛ teaspoon pepper to taste
Instructions
- Preheat the oven to 350°F/180°C
- Peel and cut the onions into wedges from the roots to the stems.
- Melt the butter in an 8-inch oven-safe skillet over a medium heat.
- Add the onions and fry for 5 minutes, using tongs to turn them occasionally, until the onions begin to brown slightly.
- Add the maple syrup and vinegar to the skillet of onions and cook for a further 5 minutes.
- Remove from the heat and arrange the onions in a pattern, then add the sprigs of thyme and season with salt and pepper.
- Lightly flour the counter and roll the pastry out so that its diameter is a little larger than the skillet.
- Place the pastry onto the skillet and tuck the edges down into the skillet. Poke two holes in the pastry with a knife to allow steam to escape.
- Place the skillet into the preheated oven and bake for 20 minutes or until the pastry is golden. Remove from the oven and allow to cool for 5 minutes.

Notes
- 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.
