Creating this dish is as enjoyable as savoring it. Here’s how you can bring the best cheesy chicken pasta to life in your kitchen:

1. **Cook the pasta:** Begin by cooking the pasta in a large pot of salted boiling water according to the package instructions. Once al dente, drain and set aside.

2. **Prepare the chicken:** In a large skillet, heat the olive oil over medium heat. Add the diced chicken, seasoning with salt and pepper. Cook until the chicken is golden and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set aside.

3. **Sauté the aromatics:** In the same skillet, add a bit more olive oil if needed. Sauté the chopped onion until translucent, about 3 minutes. Add the garlic and cook for another minute, savoring the fragrant aroma.

4. **Create the sauce:** Pour in the chicken broth, scraping up any browned bits from the bottom of the skillet. Stir in the heavy cream, bringing the mixture to a gentle simmer.

5. **Melt the cheese:** Gradually add the mozzarella and Parmesan cheeses, stirring until the sauce is smooth and creamy. Adjust the seasoning with additional salt and pepper if needed.

6. **Combine everything:** Return the chicken to the skillet, followed by the cooked pasta. Toss everything together until the pasta is well-coated with the luscious cheese sauce.

7. **Garnish and serve:** Finish with a sprinkle of fresh basil or parsley for a burst of color and flavor. Serve immediately, and enjoy the cheesy goodness.
