Ingredients
3/4 lb. dried fettucine
1 large head of broccoli, cut into florets
1 tbsp. butter
1 tbsp. extra-virgin olive oil (plus more to coat pasta)
1 large onion, sliced into half moons
Kosher salt, to taste
Pinch of granulated sugar (optional)
1 c. plain, unsweetened Greek yogurt (preferably 2% or full-fat)
1 c. Parmesan cheese, grated
1/2 lemon
Preparation
Step 1Cook the Pasta: Bring a large pot of water to boil. Cook pasta according to package directions. Add the broccoli to the pot during the last 2 minutes of the pasta cooking. Reserve 1 cup of cooking water. Drain pasta. Toss with olive oil and set aside. Step 2Cook the Onions: Heat butter and olive oil over medium heat. Add onions, a pinch of sugar (if using) and salt to taste. Cook, stirring occasionally, until soft and caramelized—about 20 minutes. If the onions are browning to quickly, turn down the heat and add a splash of water. Step 3Make the Sauce: Meanwhile, whisk together cheese and yogurt in a medium bowl. When fully combined, add the reserved cooking liquid gradually until the mixture is smooth. Step 4When the onions are finished cooking, add the pasta and broccoli to the skillet and stir. Pour in the sauce and toss until fully combined, adding more pasta cooking liquid if the sauce is too thick. Squeeze lemon juice over pasta. Serve.
