Cook the penne pasta in a large pot of salted boiling water until al dente, according to package instructions. Add the broccoli florets during the last 3 minutes of cooking. Drain and set aside.
Season the chicken pieces with Italian seasoning, paprika, salt, and pepper.
Cook the Chicken
Heat olive oil in a large skillet over medium-high heat.
Add the seasoned chicken and cook for 5-7 minutes, stirring occasionally, until fully cooked and golden brown. Remove the chicken from the skillet and set it aside.
Make the Alfredo Sauce
In the same skillet, melt the butter over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute.
Pour in the heavy cream and simmer for 2-3 minutes, stirring occasionally.
Gradually whisk in the Parmesan cheese until the sauce is smooth and creamy. Season with salt and pepper to taste.
Combine and Serve
Add the cooked pasta, broccoli, and chicken to the skillet with the Alfredo sauce. Toss everything together to coat evenly.
Cook for 2-3 minutes over low heat until warmed through.
Garnish with parsley and extra Parmesan cheese, if desired. Serve hot.
Notes
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of milk or cream to revive the sauce.Avoid freezing this dish as the cream-based sauce may separate upon thawing.
