If you're looking for a simple weeknight pasta dish, look no further. This vegetarian dinner is done in only 20 minutes and packs plenty of broccoli along with creamy goodness thanks to mascarpone cheese and low-fat Greek yogurt.
Bring a large saucepan of water to a boil. Add pasta and cook according to package directions. Reserve 1/2 cup of the cooking water. Drain the pasta and return to the pot.
Meanwhile, heat oil in a large skillet over medium-high heat. Add onion and cook, stirring, for 1 minute. Add broccoli, salt and crushed red pepper; cook, stirring, until the vegetables are soft, about 3 more minutes. Remove from heat.
Whisk mascarpone, yogurt, garlic powder and the reserved pasta water together in a small bowl. Add to the pasta along with the broccoli mixture. Stir well to coat. Cover and let stand for 5 minutes before serving. Sprinkle with Parmesan cheese, if desired.
