Easy Caramelized Onion Tart step by step
- For the crust: combine all ingredients in a Tupperware container. Close the lid and shake it vigorously until dough comes together. Press the ball of dough in a tart pan lined with baking paper. Pierce with a fork.
- For the filling: heat a small amount of oil in a wide pan over medium low heat. Add the onions and cook for around 20min, until jammy but not browned! Season to taste, add sugar, vinegar and butter.
- Pour the filling into the crust and bake in a 180°C/350°F oven for 30min or until onions are caramelized and the crust is a bit golden. I bake this tart on the lower oven rack to prevent onions from burning.
