Prep your chicken. Shred or chop cooked chicken into bite-size pieces. If using canned chicken, drain it well and pat dry to avoid a watery dip.
Whip the cottage cheese. Add cottage cheese to a blender or food processor. Blend until completely smooth and creamy, 30 to 60 seconds.
Scrape down the sides as needed.
Stir in the creaminess. Transfer the whipped cottage cheese to a mixing bowl. Fold in Greek yogurt (or sour cream) until well combined and silky.
Flavor it up. Add buffalo sauce, ranch seasoning (or your spice blend), garlic powder, and onion powder. Stir, then taste.
Adjust heat and saltiness by adding more buffalo sauce or a pinch of salt as needed.
Cheese and chicken go in. Mix in about 3/4 of the shredded cheese and all of the chicken. If using blue cheese, fold in a couple tablespoons now for a bolder flavor.
Choose your path: baked or stovetop. Baked: Preheat oven to 350°F (175°C). Spread the dip in an oven-safe dish, top with remaining shredded cheese, and bake 18–22 minutes until hot and bubbly with lightly golden edges.
Stovetop/no-bake: Warm the mixture in a skillet over medium-low heat, stirring until hot and melty.
Sprinkle cheese on top, cover, and let it melt off-heat.
Finish and serve. Drizzle with a little extra buffalo sauce, sprinkle green onions or parsley, and add blue cheese crumbles if you like. Serve warm with your favorite dippers.
