Ingredients
Method
Cooking Pasta and Broccoli
- Bring a large pot of generously salted water to a boil.
- Cook the penne according to package directions until al dente.
- During the last 3 minutes of the pasta’s cooking time, add the broccoli florets directly to the pasta water.
- Before draining, reserve 1 cup of starchy pasta water in a measuring cup, then drain the pasta and broccoli together and set aside.
Making the Sauce
- In your largest skillet, heat the olive oil and 2 tablespoons butter over medium-low heat.
- Add the diced onion and cook for 4–5 minutes until softened and translucent.
- Add the minced garlic and cook about 30 seconds more, until fragrant.
- Pour in the heavy cream and chicken broth, and bring the mixture to a gentle simmer for 2–3 minutes.
- Remove the skillet completely from the heat before adding the cheeses to prevent the sauce from becoming grainy.
- Whisk in the Parmesan and mozzarella until the sauce is completely smooth.
- Season with Italian seasoning, garlic powder, salt, pepper, and red pepper flakes if using.
Combining Ingredients
- Add the drained pasta and broccoli to the creamy sauce and toss gently with tongs to coat everything evenly.
- Fold in the shredded rotisserie chicken last so the pieces stay tender.
- Add the reserved pasta water 2 tablespoons at a time until you reach a creamy, glossy consistency that clings to the pasta.
- Stir in a cold knob of butter just before serving for a silky finish.
Notes
Serve hot with an extra sprinkle of freshly grated Parmesan and a crack of black pepper. A squeeze of lemon over individual portions brightens the richness. Pair with a crisp green salad or crusty bread to mop up any remaining sauce. Cool to room temperature within two hours, then refrigerate for up to 3–4 days.
