Tarte Alsace

True to Alsacian culinary tradition… Just kidding, I know nothing about that, but this tart looked really good. My hubby is not a fan of carmelized onions, but he liked it as well. Cooking tip: careful taking it out of the box and putting it in the oven if it defrosts. It gets really flimsy and you are supposed to put it straight on the rack. When it bakes, it stiffens, so it’s easy to take out. Eat it while it’s warm, otherwise the dough gets hard. Not good leftovers, but hey, it’s 8oz and so delicious, so that shouldn’t be a problem.
