1-First Step: Cook the pasta Bring a pot of salted water to a boil and cook 1/3 pound pasta according to the package directions. Pick a shape that can hold creamy sauce well, such as penne or rotini. Once the pasta is done, drain it and set it aside. If you want to save time, you can start the skillet sauce while the pasta cooks.

2-Second Step: Soften the onion in butter Place a large skillet over medium heat and add 3 tablespoons butter. Once the butter melts, add 1/3 onion, chopped small. Cook for about 3 minutes, stirring now and then, until the onion softens and starts to smell sweet. This gives the sauce a nice base and helps the final dish taste richer.

3-Third Step: Add the mushrooms and broccoli Stir in 3 medium cremini mushrooms, sliced, plus 2 cups broccoli cut into small florets. Cook for about 2 minutes. You want the broccoli to turn bright green and the mushrooms to soften a bit, but not get mushy. If you are using frozen broccoli, let it cook a little longer so extra water has time to cook off.

4-Fourth Step: Add the chicken Take 1 chicken breast from rotisserie chicken and slice it into small pieces. Add the chicken to the skillet and stir it through the vegetables. Since the chicken is already cooked, it only needs to warm up. This is one of the best parts of using rotisserie chicken because it keeps the meal fast and juicy.

5-Fifth Step: Pour in the cream Add 1 cup cream to the skillet and bring the mixture to a boil. Once it starts bubbling, turn the heat down to medium and let it cook for another 3 minutes. Stir gently so the sauce stays smooth and does not scorch on the bottom of the pan. The cream should thicken slightly and begin coating the chicken and vegetables.

6-Sixth Step: Add cheese and seasoning Lower the heat and stir in 1/2 cup Parmesan cheese, freshly grated. Add 1/8 teaspoon salt and freshly grated pepper to taste. The cheese will melt into the sauce and give it that classic creamy Alfredo feel. Taste and adjust the pepper if you want a little more bite.

7-Seventh Step: Combine with the pasta Add the cooked pasta to the skillet and mix everything well so the sauce coats each piece. If the sauce feels too thick, splash in a little pasta water to loosen it. If you want a one-pot style dinner, you can add the pasta to the skillet directly and toss it with the sauce there. That is a helpful trick for busy nights when you want fewer dishes.

8-Final Step: Plate and serve Spoon the Rotisserie Chicken Broccoli Pasta into bowls or onto plates. Garnish with chopped green onions and extra Parmesan cheese. Serve while hot so the sauce stays creamy and smooth. The final dish should look rich, colorful, and inviting, with green broccoli, golden mushrooms, and a glossy sauce.
