Cook the pasta according to package directions until al dente, about 8–10 minutes.
Drain the pasta and rinse under cold water to stop the cooking process.
Allow the pasta to cool completely and drain well.
In a large mixing bowl, combine the cooled pasta, cooked chicken, chopped romaine lettuce, and cherry tomatoes.
Pour the Caesar dressing over the mixture.
Gently toss until all ingredients are evenly coated.
Add the Parmesan cheese and mix well.
Season with salt and black pepper to taste.
For the best Chicken Caesar Pasta Salad texture, sprinkle the crushed croutons over the top just before serving.
Garnish with fresh parsley or basil if desired and serve immediately.
