Caramelized Onion Flatbread
A caramelized onion flatbread recipe? ABSOLUTELY and it is extremely delicious! Imagine caramelized onions on a delightful fluffy soft dough, with cheese, and you will be in savory cake heaven. In German this recipe is called “Zwiebelkuchen vom Blech” directly translated it means onion sheet cake. However, it is not a “cake” but rather a type of flatbread or even pizza. Onion cake does not sound as tantalizing as caramelized onion flatbread. There is definitely no sugar except a pinch to help the dough rise.
This recipe was one of my German aunt’s favorite go-to recipes. It is a delicious German recipe that feeds many hungry mouths affordably (which is why I know she loved this recipe, plus the fact that is tastes awesome). This caramelized onion flatbread recipe will get constant comments about how good it is. It will make you feel delighted in your skills as a home chef, lol, no seriously it will. You will need to give the dough a little rise time but otherwise this caramelized onion flatbread recipe does not take too much time to make. If you make the dough thicker (just don’t roll it out as thin) it kind of reminds me of a deep dish pizza but with more pizzazz.
You can also make this dough and topping ahead and keep it in the fridge overnight. To keep the dough from drying out rub it with oil and cover with a towel. Then proceed to rolling the dough out and spreading on the topping the next day.
The dough is like a basic pizza dough recipe only it turns out a little softer and more tender because of the milk and oil. You will love the soft chew of this dough. Exact quantities are in the recipe card below. You will need milk, flour, yeast, sugar, salt, and oil.
Mix the flour and yeast.
Add the rest of the ingredients for the dough and the milk and knead.
Cover with a towel and allow the dough to rise for 1 hour.
The topping can be cooked while the dough it rising. You will need a scale because converting kg to cups for onions is not accurate.
