1-First Step: Cook the pasta Start by cooking 1/3 pound pasta according to the package directions. This is the easiest way to get the texture right, whether you are using penne, rotini, fettuccine, or another favorite shape. While the pasta cooks, you can move right into the sauce, which keeps this Rotisserie Chicken Broccoli Pasta recipe moving fast. For best results, salt the pasta water if your package does not already suggest it. That small step gives the noodles a little more flavor before they are mixed with the sauce. Drain the pasta when it is just tender, since it will cook a tiny bit more once it hits the skillet.

2-Second Step: Cook the onion in butter Chop 1/3 onion and place it in a large skillet with 3 tablespoons butter over medium heat. Cook the onion until it becomes soft, which should take about 3 minutes. You want the onions to turn fragrant and slightly golden, not browned. This step gives the sauce a savory base. The butter and onion work together to create that cozy, homemade flavor that makes Rotisserie Chicken Broccoli Pasta taste so comforting. If you like a little extra sweetness, let the onions cook just until they are tender and translucent.

3-Third Step: Add the mushrooms and broccoli Slice 3 medium cremini mushrooms and add them to the skillet along with 2 cups broccoli florets. Cook for 2 more minutes, stirring now and then. The mushrooms will soften and the broccoli will turn a bright green while staying a little crisp. If you prefer softer vegetables, let them cook for another minute, but do not overdo it. The best version of this pasta has vegetables that still taste fresh. This is also the stage where you can toss in extra vegetables if you want, such as corn, zucchini, eggplant, bell peppers, or olives. That makes the recipe even more flexible for families with different tastes.

4-Fourth Step: Add the rotisserie chicken and cream Slice the cooked chicken breast from the rotisserie chicken into small pieces and add it to the pan. Pour in 1 cup cream and stir everything together. Bring the mixture to a boil, then reduce the heat to medium and cook for 3 minutes. The sauce should start to thicken slightly while the chicken warms through. This is where you need to be careful not to overcook the chicken. Since it is already cooked, it only needs to simmer for a few minutes. If you are using leftover chicken thighs or drumsticks, remove the meat from the bone first, chop it, and take off the skin. If you have frozen leftover chicken, dice it, store it in a zip lock bag, then thaw it in the fridge overnight or use warm water or microwave defrost if needed.

5-Fifth Step: Add the cheese and pasta Lower the heat and add 1/2 cup freshly grated Parmesan cheese, 1/8 teaspoon salt, and freshly grated pepper. Stir until the cheese melts and the sauce becomes smooth. Then add the cooked pasta and mix everything together so the noodles are coated evenly. If the sauce looks too thick, add a splash of pasta water. If it seems a little thin, let it sit over low heat for a moment until it clings to the pasta better. The goal is a creamy, glossy sauce that coats every bite of Rotisserie Chicken Broccoli Pasta.

6-Final Step: Serve and finish Spoon the pasta into bowls or plates and top with chopped green onions and extra Parmesan cheese. The green onions add freshness and color, while the extra cheese gives every serving a salty finish. Serve right away while it is warm and creamy.
