Frittata with Caramelized Onions, Goat Cheese, and Sage
Adapted from Fields of Greens
Serves 6

2 tbsp. olive oil
3 medium onions, quartered and thinly sliced
Salt and pepper
3 garlic cloves, finely chopped
8 eggs
1 ounce Parmesan cheese, grated, about 1/3 cup
1 tbsp. chopped fresh sage
3 ounces mild creamy goat cheese, crumbled
3 tbsp. Reduced Balsamic Vinegar (method follows)

Preheat oven to 325ºF.  Heat 1 tablespoon of the olive oil in a large skillet; add the onions, a large pinch of salt and a few grinds of pepper.  Sauté the onions over medium heat for about 10 minutes to release their juices.  Add the garlic; continue to cook over medium heat for about 40 minutes, gently scraping the pan with a wooden spoon to keep the onions from sticking as they caramelize.  Transfer the onions to a bowl and set aside to cool.  (DT: These can be made days in advance.  Put in an airtight container in the refrigerator.)

Beat the eggs in a medium bowl.  Stir in the onions along with the Parmesan and sage.  In a 9-inch sauté pan with an ovenproof handle, heat the remaining tablespoon of oil to just below the smoking point.  Swirl the oil around the sides of the pan to coat it.  Turn the heat down to low, then immediately pour the frittata mixture into the pan.  The eggs will sizzle from the heat.  Crumble in the goat cheese and cook over low heat for 5 minutes, until the sides begin to set; transfer to the oven and bake, uncovered, for 20 to 25 minutes, until the frittata is golden and firm.

Loosen the frittata gently with a rubber spatula; the bottom will tend to stick to the pan.  Place a plate over the pan, flip it over, and turn the frittata out.  Brush the bottom and sides with the vinegar and cut into wedges.  Serve warm or at room temperature.

For the balsamic vinegar, heat 6 tablespoons of vinegar in a small saucepan and cook down gently until it is reduced by half.  If you want to have some of these amazing taste treat on hand, just make extra and store it in the refrigerator.  This process goes quickly, so watch your pot carefully.
