Bake the biscuits first, Then put on the carmelized onions. Works for me.

My five stars are based on how simple this is to make, and how many it can serve. I agree with the review that you can double the dough recipe and still have plenty of topping. I added a ricotta cheese base that made the onion tart spectacular. Mix one cup ricotta cheese, one egg, and one tsp powdered sugar(enough topping for double dough recipe). Spread a thin amount on the flattened tart and top with onion. Delicious and surprisingly impressive. Your guests will say something for sure.

The proportions of this recipe need to be worked on. I didn't have enough dough, and way too much onion. Also, the tarts never browned, and started to burn quickly. The rose too much, pushing the onion off of the top. More dough, bigger tarts, and they would rock.

good recipe, but not tarts, more of an onion biscuit. liked the carmelized onions, liked the biscuits, just not together for and appetizer...a little too much dough.
