1
Heat the oil in a large skillet or stockpot over medium heat.
-
2
Add the onions and a generous seasoning of salt and pepper.
-
3
Toss to coat well, then cover the pan.
-
4
Cook, tossing occasionally, until the onions are very soft and are caramel brown all over.
-
5
After the first 10 minutes or so of cooking, you will have to lower the heat to prevent sticking.
-
6
The onions need to be cooked slowly over low heat in order to caramelize properly; this will take about 45 minutes.
-
7
By cooking them covered, you can use less oil to achieve this.
-
8
Remove the cover from the pan, then add the walnuts.
-
9
Cook 5 minutes, tossing frequently.
-
10
Remove the onions from the heat and let cool.
-
11
To make the crust, preheat the oven to 450 degrees.
-
12
Combine the flour, baking powder, and salt in a large bowl and mix thoroughly.
-
13
Pour in the beer and mix well.
-
14
The dough will be sticky.
-
15
Spread a handful of flour on your work surface and dump the dough onto it.
-
16
Toss the dough around to coat it with the flour and prevent it from sticking.
-
17
Knead it 2 or 3 times to make it pliable.
-
18
Shape the dough into a ball, then divide it in two.
-
19
Grease 2 baking sheets.
-
20
Use a rolling pin to roll each ball into an 11 or 12 inch circle.
-
21
Spread half the onion mixture onto each pizza.
-
22
Sprinkle the crumbled goat cheese all over each pizza.
-
23
I like to cook one pizza at a time, but you can cook the pizzas on 2 different oven racks and alternate them halfway through the cooking.

24
Bake 12 to 15 minutes, or until golden brown on top or underneath
