Cook the pasta: Boil in well-salted water until just al dente.
Protein pastas can overcook fast, so check a minute early. Drain and rinse under cold water to stop cooking.
Dry it off: Shake the colander and spread pasta on a sheet pan for 5 minutes. Drier pasta holds dressing better and prevents sogginess.
Mix the dressing: In a large bowl, whisk Greek yogurt, mayo, buffalo sauce, ranch seasoning, and lemon juice.
Add 1β2 tablespoons water until itβs creamy and pourable. Season with salt and pepper.
Toss the base: Add cooled pasta to the bowl with dressing. Fold until every piece is lightly coated.
Add protein and crunch: Stir in chicken, celery, carrots, tomatoes, corn, and red onion.
Taste and adjust buffalo or salt to your liking.
Finish with extras: Fold in blue cheese and parsley. If using avocado or bacon, add right before serving for best texture.
Chill and set: Cover and refrigerate for at least 30 minutes. This helps the flavors meld and the dressing cling to the pasta.
Serve: Give it a quick stir.
If it looks a bit thick, splash in a tablespoon of water or a drizzle of buffalo sauce and toss again.
