Blue Cheese Dip
jump toRECIPE
This recipe is based on the dip at Keen’s Steakhouse in Manhattan where a thick, sour cream based blue cheese dip is served as an appetizer on the house alongside sliced celery, carrots and a pickle with the bread service. Their recipe tasted almost like the perfect cross between blue cheese dressing and a creamy buttermilk ranch, and I knew I had to recreate it. While this recipe is thicker so it can be served as a dip, you can also thin it with a bit more buttermilk to serve as a salad dressing. I’ve provided instructions for thinning the dressing below. Big fan of these flavors? Then you’ll love blue cheese chips.

Key Ingredients for This Recipe
- Blue cheese – Blue veined cheese has a characteristic sharp, salty flavor. Pick a creamy blue cheese you can crumble yourself rather than one that is pre-crumbled. Some varities that crumble well include Maytag, Roquefort, Gorgonzola or Danish blue.
- Sour cream – The base of this recipe is sour cream. It adds a tangy flavor while keeping the texture thicker. I recommend using a full-fat sour cream for the best texture.
- Mayonnaise – The emulsified sauce has flavors that lend itself well to rounding out dips like this one.
- Buttermilk – The typical American buttermilk is low-fat. It also has a rich, tangy flavor and a texture more similar to sour cream or yogurt than cream or milk. Add additional buttermilk to thin the dip into a dressing.
- Garlic – Grating the garlic on a microplane allows it to combine more seamlessly into the sauce.
- Green onions – Finely chopped green onions add a subtle oniony flavor to the blue cheese.
