Grate the sharp cheddar cheese and let it reach room temperature before mixing.

In a large mixing bowl, combine whipped cream cheese, grated cheddar, ranch seasoning, Dijon mustard, and sour cream until smooth.

Fold in the diced green onions until evenly distributed.

Cover and refrigerate for at least two hours or overnight for best flavor.

To serve warm, transfer to a crockpot on low heat, stirring until melted, about 15-20 minutes; for cold, serve directly from the fridge.

Arrange soft pretzels, chips, or toasted bread around the dip for serving.
