Caramelized Onion, Walnut, and Goat Cheese Pizza with a Beer Crust
2 tablespoons olive oil
3 pounds (6 large) onions, very thinly sliced
Salt to taste
Freshly ground black pepper to taste
1/2 cup finely chopped (not ground) walnuts
Heat the oil in a large skillet or stockpot over medium heat.
Add the onions and a generous seasoning of salt and pepper.
Toss to coat well, then cover the pan.
Cook, tossing occasionally, until the onions are very soft and are caramel brown all over.
After the first 10 minutes or so of cooking, you will have to lower the heat to prevent sticking. The onions need to be cooked slowly over low heat in order to caramelize properly; this will take about 45 minutes.
By cooking them covered, you can use less oil to achieve this.
Remove the cover from the pan, then add the walnuts.
Cook 5 minutes, tossing frequently. Remove the onions from the heat and let cool.
