Ingredients

1 lb penne pasta (Barilla holds sauce beautifully)
1 whole rotisserie chicken, shredded (3-4 lbs, about 4 cups meat)
4 cups fresh broccoli florets (frozen works if you are in a pinch)
2 tbsp olive oil
3 cloves garlic, minced fine
1 medium yellow onion, diced small
2 tbsp butter
1 cup heavy cream
1/2 cup low-sodium chicken broth
1 cup freshly grated Parmesan cheese
1/2 cup whole milk mozzarella, shredded
1 tsp Italian seasoning
1/2 tsp garlic powder
Salt and black pepper to taste
1/4 tsp red pepper flakes (optional but adds nice warmth)

Step-by-Step Instructions

Boil the Pasta and Broccoli: Bring a large pot of salted water to a boil. Cook the penne pasta according to package directions until al dente. During the last 3 minutes of cooking time, add the broccoli florets directly to the pasta water to blanch them until tender-crisp.
Reserve Water and Drain: Before draining, reserve 1 cup of starchy pasta water in a measuring cup. Drain the pasta and broccoli together in a colander and set aside.
Sauté Aromatics: Heat the olive oil and 2 tablespoons of butter in a large skillet over medium-low heat. Cook the diced onion for 4-5 minutes until softened and translucent. Add the minced garlic and cook for just 30 seconds until fragrant, being careful not to let it brown.
Simmer the Sauce Base: Pour in the heavy cream and chicken broth. Bring the mixture to a gentle simmer for 2-3 minutes. Look for small bubbles around the edges rather than a rolling boil to prevent the cream from breaking.
Whisk in Cheese: Remove the skillet from the heat completely. This is a crucial step to prevent graininess. Whisk in the Parmesan and mozzarella cheeses until the sauce is completely smooth. Season with Italian seasoning, garlic powder, salt, pepper, and red pepper flakes.
Combine Everything: Add the drained pasta and broccoli to the creamy sauce, tossing gently with tongs to coat evenly. Fold in the shredded rotisserie chicken. If the sauce is too thick, add the reserved pasta water 2 tablespoons at a time until it reaches a glossy, creamy consistency.
The Finishing Touch: Stir in a small cold knob of butter just before serving to create a silky, restaurant-quality finish.

Expert Tips / Pro Tips

To ensure the best results for your Rotisserie Chicken Broccoli Pasta, always grate your own Parmesan cheese from a block. Pre-shredded cheeses are coated in potato starch to prevent clumping, which can lead to a gritty sauce. Another pro tip is to use a combination of both white and dark meat from the rotisserie chicken; the dark meat adds a richer flavor and extra moisture to the dish. Finally, never skip the step of removing the skillet from the heat before adding your cheese—this is the secret to a perfectly smooth, professional Alfredo-style sauce.

If you want to customize this Rotisserie Chicken Broccoli Pasta, there are several easy swaps you can make. For a gluten-free version, simply use your favorite gluten-free penne or rotini. If you don’t have broccoli on hand, fresh baby spinach or peas make excellent green additions. For those who want even more heat, increase the red pepper flakes or add a teaspoon of Cajun seasoning to the sauce. You can also substitute the rotisserie chicken with leftover grilled steak or sautéed shrimp for a different protein profile.

Serving Suggestions

This rich and creamy pasta pairs beautifully with a crisp Caesar salad to provide an acidic contrast to the heavy cream sauce. For a high-protein side, try serving it with cottage cheese flatbread which is perfect for soaking up any extra garlic-parmesan sauce. A simple green salad with a lemon vinaigrette also works well to cleanse the palate between bites. If you want to go the traditional route, a side of warm garlic bread or roasted asparagus will round out the meal perfectly.

Storage: Store any leftovers in an airtight container in the refrigerator for up to 4 days. The flavors often deepen overnight, making it a fantastic lunch the next day.

Reheating: To maintain the creamy texture, reheat the pasta on the stovetop over low heat. Add a splash of milk or heavy cream and stir frequently to re-emulsify the sauce. Avoid high heat in the microwave, as it can cause the fats in the cheese to separate and become oily.

Freezing: While you can freeze this dish, the cream sauce may change texture upon thawing. If you do freeze it, thaw it overnight in the fridge and reheat slowly on the stove with extra cream.

FAQ

Can I use frozen broccoli for this recipe?

Yes, frozen broccoli works well. You can add it to the boiling pasta water during the last 3 minutes just like fresh broccoli. Just ensure it is heated through before draining.

How do I prevent the cheese sauce from becoming grainy?

The key is to remove the pan from the heat source before whisking in the cheese. High heat causes the proteins in the cheese to clump, resulting in a grainy texture. Using freshly grated cheese also helps significantly.

What is the best type of rotisserie chicken to use?

An herb-seasoned or traditional rotisserie chicken works best. Avoid “lemon pepper” or “BBQ” flavored chickens unless you want those specific flavors to dominate the creamy Italian sauce.

Can I make this pasta ahead of time?

You can prepare the components ahead of time, but the sauce is best when served immediately. If you must make it ahead, undercook the pasta slightly so it doesn’t get mushy when reheated.
