Caramelized onion, sausage and basil pizza

Again, I can't take full (or any) credit for this recipe since it is actually one of Giada de Laurentiis' recipes, but it was delicious and easy and worth sharing :) We used way more cheese than the recipe calls for, but we're also big fans of blue cheese. If there's a Whole Foods near you, they make excellent, ready-made pizza dough if you don't feel like going to the work of making homemade pizza dough, although they sell it in 22 oz packages, so either split it and save the rest for later in the week or make two pizzas if you have lots of mouths to feed!

Ingredients

Cornmeal, for dusting
3 tablespoons extra-virgin olive oil, plus extra for drizzling (I didn't think this was necessary as the sausage had enough residual fat).
1 tablespoon unsalted butter, at room temperature
2 onions (about 1 1/2 pounds), thinly sliced
1/4 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
1 pound spicy turkey or pork sausage, casings removed, crumbled
All-purpose flour, for dusting
1 (13 to 16-ounce) ball pizza dough
3/4 cup (3 ounces) crumbled Gorgonzola or blue cheese
1/4 cup chopped fresh basil leaves

Directions

Put an oven rack in the center of the oven. Preheat the oven to 475 degrees F. Sprinkle a heavy baking sheet with cornmeal and set aside.

In a large skillet, melt 3 tablespoons of olive oil and the butter over medium-low heat. Add the onions, salt and pepper. Cook, stirring occasionally, until golden and caramelized, about 20 minutes. Increase the heat to medium-high and add the sausage. Using a wooden spoon, break up the sausage and cook, stirring constantly, until cooked through, about 8 minutes. Set aside to cool slightly.

On a lightly floured work surface, roll out the dough into a 13-inch diameter circle, about 1/4-inch thick. Transfer the dough to the prepared baking sheet and drizzle with olive oil. Spread the onion mixture evenly over the dough, leaving a 1-inch border. Sprinkle the cheese on top. Bake until the crust is golden and the cheese has melted, about 15 to 17 minutes. Remove from the oven and sprinkle with chopped basil. Cut the pizza into wedges and serve.
