Creamy Keto Blue Cheese Dressing

This creamy keto blue cheese dressing combines rich sour cream, mayonnaise, and bold blue cheese crumbles for a thick, tangy, and ultra-satisfying sauce that is perfect for low-carb lifestyles. A splash of apple cider vinegar brightens the flavor while garlic and onion powder add savory depth without adding carbs. Use it as a classic salad dressing, a dip for wings and crunchy keto veggies, or a sauce for bunless burgers and grilled meats.

Ingredients

For the creamy keto blue cheese dressing

3/4 cup sour cream full-fat
1/2 cup mayonnaise sugar-free, preferably avocado oil or olive oil based
3/4 cup blue cheese crumbles divided, use a good-quality, crumbly blue cheese
2 tablespoons apple cider vinegar or to taste
1 tablespoon water more as needed to thin for dressing consistency
1 teaspoon garlic powder
3/4 teaspoon onion powder
1/4 teaspoon fine sea salt or to taste, blue cheese saltiness can vary
1/4 teaspoon freshly ground black pepper or to taste

Instructions

Add the sour cream and mayonnaise to a medium mixing bowl and whisk until smooth and well combined.
Stir in about half of the blue cheese crumbles, mashing some of them gently with the back of a spoon or whisk to help thicken and flavor the base.
Whisk in the apple cider vinegar, water, garlic powder, onion powder, salt, and black pepper until the dressing is smooth and creamy.
Fold in the remaining blue cheese crumbles to leave some larger pieces throughout the dressing for extra texture.
Adjust the consistency by adding a small splash of water at a time for a pourable salad dressing or leaving it thicker for a dip or burger sauce.
Taste and adjust seasoning with additional salt, pepper, or vinegar if desired, keeping in mind that the flavors will intensify as the dressing chills.
Transfer the dressing to an airtight container or mason jar, cover, and refrigerate for at least 1 hour to allow the flavors to meld before serving.
Stir the dressing just before serving and use to drizzle over salads, serve with wings and keto-friendly veggies, or spoon onto bunless burgers and grilled meats.

Notes

This dressing will thicken as it chills, so thin with a splash of water or unsweetened almond milk just before serving if you prefer a looser consistency for salads. Store in an airtight container in the refrigerator for up to 7 days and give it a good stir before each use, as some separation is natural. For a milder flavor, reduce the blue cheese slightly and add a bit more sour cream; for extra funk, increase the blue cheese and a touch more vinegar. Always check that your mayonnaise is sugar-free to keep the dressing strictly keto-friendly.
