Method
- Bring a large pot of salted water to boil. Cook penne pasta according to package directions until al dente. During the last 3 minutes of cooking, add broccoli florets to the pasta water.
- Before draining, reserve 1 cup of pasta cooking water. Drain pasta and broccoli together and set aside.
- 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. Bring to a gentle simmer for 2-3 minutes, looking for small bubbles around the edges rather than a rolling boil.
- Remove skillet from heat completely. Whisk in Parmesan and mozzarella until completely smooth. Season with Italian seasoning, garlic powder, salt, pepper, and red pepper flakes if using.
- Add drained pasta and broccoli to the sauce, tossing with tongs to coat everything evenly. Fold in shredded rotisserie chicken.
- Add reserved pasta water 2 tablespoons at a time until sauce reaches a creamy, glossy consistency. Stir in a cold knob of butter just before serving for extra richness.
Notes
Storage: Store in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of cream or broth to restore sauce consistency. Lighter Version: Use half-and-half instead of heavy cream and reduce cheese by half. Pasta water helps maintain creaminess. Protein Swaps: Leftover turkey, cooked shrimp, or Italian sausage work beautifully. Vegetable Additions: Sautéed mushrooms, sun-dried tomatoes, or roasted red peppers complement the base recipe. Always remove pan from heat before adding cheese to prevent graininess. Use freshly grated Parmesan for smoothest sauce.
