Ingredients
Method
Cooking Pasta and Broccoli
- Bring a large pot of salted water to a boil and cook penne pasta according to package directions until al dente.
- During the last 3 minutes of cooking time, add broccoli florets directly to the pasta water.
- Before draining, reserve 1 cup of starchy pasta water in a measuring cup. Drain pasta and broccoli together and set aside.
Making the Sauce
- Heat olive oil and butter in your largest skillet over medium-low heat.
- Cook diced onion for 4-5 minutes until softened, then add minced garlic for 30 seconds until fragrant.
- Pour in heavy cream and chicken broth, bringing mixture to a gentle simmer for 2-3 minutes, avoiding a rolling boil.
- Remove skillet from heat completely before adding cheese to prevent graininess.
- Whisk in Parmesan and mozzarella until completely smooth, then season with Italian seasoning, garlic powder, salt, pepper, and red pepper flakes.
Combining and Serving
- Add drained pasta and broccoli to the creamy sauce, tossing gently with tongs to coat everything evenly.
- Fold in shredded rotisserie chicken last.
- Add reserved pasta water 2 tablespoons at a time until you reach a creamy, glossy consistency.
- Stir in a cold knob of butter just before serving for a restaurant-quality finish.
- Serve hot, topped with extra grated Parmesan and a light sprinkle of black pepper or red pepper flakes.
Notes
Cool leftover pasta to room temperature; store in an airtight container in the fridge for up to 3 days. Add a splash of broth or milk when reheating to restore the sauce's silkiness.
