Mash the cheese: In a medium bowl, add half of the blue cheese.
Use a fork to mash it into a paste. This helps infuse the dressing with bold blue cheese flavor.
Add the creamy base: Stir in the mayonnaise and sour cream until smooth and well combined.
Season and brighten: Add Dijon, garlic, lemon juice (start with 1 tablespoon), salt, and pepper. Mix thoroughly.
Adjust the texture: Stir in heavy cream or almond milk, 1 tablespoon at a time, until itβs your preferred consistency.
Keep it thick for dipping or thinner for salads.
Fold in chunks: Add the remaining blue cheese crumbles for texture. Fold gently so you keep some chunks intact.
Taste and tweak: Add more lemon juice, salt, or pepper if needed. Stir in chopped chives or parsley if using.
Rest and serve: For best flavor, cover and chill for at least 30 minutes before serving.
The flavors deepen as it rests.
