Blue Cheese Avocado Dressing

Why This Blue Cheese Avocado Dressing Works

As the avocado gets mashed, it turns very smooth and creamy. That soft avocado gives the dressing a thick base, so it feels rich without needing a ton of mayonnaise. When the sour cream, mayonnaise, and buttermilk go in, they loosen that thick mash just enough so it can pour, but they still keep it full and velvety instead of runny.

Once the blue cheese is mixed in, some of the crumbles stay in tiny pieces and some blend into the creamy base. The blended part spreads the blue cheese taste through the whole dressing, while the little bits give small pops of flavor and texture. Lemon juice and apple cider vinegar thin the dressing a bit more and keep the avocado from browning, so the color stays fresh and green.

When everything is hit with the immersion blender, the fat from the avocado, sour cream, mayo, and cheese grabs onto the buttermilk and vinegar. That’s why the dressing stays smooth and doesn’t separate, even after sitting in the fridge.

Mistakes To Avoid

Using an underripe or very hard avocado makes the dressing grainy and pasty. The blender has to work harder, the avocado doesn’t fully break down, and the dressing ends up with tiny hard bits instead of a smooth, creamy texture.

Adding way more buttermilk than listed turns the dressing into a thin, runny liquid. The blue cheese and avocado can’t hold it together, so it pours like milk and slides off salad or wings instead of lightly coating them.

Skipping the blending step and only stirring everything together leaves big chunks of blue cheese and avocado. The fat from the cheese and mayo doesn’t fully mix with the liquids, so the dressing separates in the jar and looks curdled instead of even and creamy.

Letting the dressing sit out warm for hours instead of chilling it in the fridge makes it looser and more oily. The fats soften too much, the mixture thins out, and it can develop a greasy layer on top instead of staying thick and smooth.
