01 - Prepare pasta according to package directions. Drain thoroughly, rinse under cold water to stop cooking, and set aside to cool completely.
02 - In a large mixing bowl, whisk together sour cream, mayonnaise, and ranch seasoning mix until completely smooth and well combined.
03 - Add cooled pasta to the dressing mixture. Gently fold in cheddar cheese, crispy bacon, thawed peas, and sliced green onions until evenly distributed.
04 - Refrigerate pasta salad for at least 1 hour to allow flavors to meld and develop. The salad tastes best when thoroughly chilled.
05 - Top with additional bacon, cheddar cheese, or green onions if desired. Serve cold alongside grilled meats, BBQ, or as a standalone dish.
