Creating Creamy Caprese Pasta Salad is a breeze when you follow these simple steps:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the rotini pasta and cook according to package instructions until al dente. Drain and rinse under cold water to cool.

2. Prepare the Dressing: In a mixing bowl, combine the mayonnaise, sour cream, balsamic vinegar, olive oil, salt, and pepper. Whisk until smooth.

3. Combine Ingredients: In a large mixing bowl, add the cooled pasta, cherry tomatoes, mozzarella balls, and chopped basil.

4. Mix with Dressing: Pour the dressing over the pasta and mix until all ingredients are evenly coated.

5. Taste and Adjust: Take a small spoonful to taste. Adjust seasoning as necessary with more salt or pepper.

6. Chill: For maximum flavor, cover the bowl and refrigerate for at least 30 minutes before serving.

7. Serve: Before serving, give the pasta salad a gentle toss to combine ingredients that may have settled.
