5 TBSP olive oil
6 c coarsely chopped onions
1 lb pasta
2 c thick, Greek yogurt
1 c pecorino romano, grated
Heat the olive oil in a large skillet over medium-high heat and add the onions. Reduce the heat to medium low and cook, stirring frequently and seasoning with salt to taste as you go, until the onions are soft and golden brown, 20 to 30 minutes.
Cook pasta according to package.
Reserve 1/2 c pasta water. Combine the yogurt with 1/4 c cooking water and mix well. Add more of the reserved pasta water as needed to get the sauce to your thickness. Drain the pasta and toss with the yogurt mixture. Serve the pasta immediately, sprinkled generously with cheese and topped with caramelized onions and their juices.
Serves 4 – 6.
