Simon and Seafort’s Blue Cheese Dressing

This recipe comes from a fellow culinary enthusiast who understands what makes blue cheese dressing truly exceptional. What sets this version apart is its complex flavor profile, achieved through the careful balance of white pepper, onion salt, and other seasonings that perfectly complement the tangy blue cheese. The first time I served this alongside crisp buffalo wings at a gathering, guests were scraping the bowl clean and requesting the recipe. Whether you’re dressing a wedge salad, dipping fresh vegetables, or serving alongside spicy wings, this homemade blue cheese dressing delivers restaurant-quality taste with just 5 minutes of effort.

Why This Recipe Works

The secret to this exceptional blue cheese dressing lies in its carefully selected seasonings. While many recipes rely solely on the blue cheese for flavor, this version incorporates white pepper for subtle heat, onion salt for savory depth, and a touch of MSG (optional) that enhances all other flavors. The combination of mayonnaise and sour cream creates the perfect creamy base, while the wine vinegar adds brightness that cuts through the richness. By mashing some of the blue cheese into the base while leaving other pieces whole, you get a dressing with both consistent flavor and those delightful cheese chunks in every bite.

Ingredients

  • Blue cheese – Delivers the signature pungent, savory character that defines the dressing
  • White pepper – Provides subtle heat without the speckled appearance of black pepper
  • MSG (optional) – Enhances the savory qualities of all other ingredients
  • Salt – Balances flavors and brings out the tanginess of the cheese
  • Onion salt – Adds savory depth and complexity that regular salt alone cannot provide
  • Salad oil – Creates smooth texture and carries flavors throughout the dressing
  • Water – Helps achieve ideal consistency without diluting flavor
  • Wine vinegar – Contributes essential acidity that balances the rich dairy components
  • Mayonnaise – Forms the creamy base and provides subtle tang
  • Sour cream – Adds luxurious texture and pleasant cultured flavor

Step-by-Step Instructions

  1. In a medium bowl, combine 1/8 teaspoon white pepper, 1 teaspoon MSG (if using), 3/4 teaspoon salt, and 1/4 teaspoon onion salt.
  2. Add 1/4 cup salad oil and 1/4 cup water to the spice mixture and whisk until well combined.
  3. Add 1 tablespoon wine vinegar and whisk to incorporate.
  4. Add 1 cup mayonnaise and 1 cup sour cream to the bowl and whisk until smooth and fully blended.
  5. Place 2 ounces blue cheese in a small dish and mash about half of it with a fork until somewhat smooth.
  6. Add the mashed and remaining crumbled blue cheese to the dressing mixture.
  7. Stir gently to incorporate the cheese, leaving some small chunks intact for texture.
  8. Cover and refrigerate for at least 30 minutes before serving to allow flavors to meld.

Ingredients

  • 1/8 teaspoon White Pepper
  • 1 teaspoon MSG (optional)
  • 3/4 teaspoon Salt
  • 1/4 teaspoon Onion salt
  • 1/4 cup Salad oil
  • 1/4 cup Water
  • 1 tablespoon Wine Vinegar
  • 1 cup Mayonnaise
  • 1 cup Sour Cream
  • 2 ounces Blue Cheese

Instructions

  • Mix all the spices with the salad oil and water.
  • Blend in the vinegar, mayonnaise, and sour cream.
  • Mash the blue cheese and stir into the dressing.

Notes

For the most complex flavor, use a good quality blue cheese like Danish blue, Roquefort, or Gorgonzola. The MSG is completely optional—while it enhances the umami quality of the dressing, you’ll still get excellent results without it. If you prefer a thinner consistency, simply add 1-2 additional tablespoons of water. For those who enjoy a more pronounced cheese flavor, increase the blue cheese to 3 ounces. The dressing actually improves after sitting overnight in the refrigerator, as this allows the blue cheese flavor to fully permeate the mixture.

Dietary Modifications

Lower Fat Version

Use light mayonnaise and light sour cream to reduce fat content. The texture will be slightly less rich, but the flavor will still be excellent.

Without MSG

Simply omit the MSG if preferred. The dressing will still have excellent flavor from the other seasonings and the blue cheese itself.

Lower Sodium Option

Reduce or eliminate the added salt and use low-sodium mayonnaise. The blue cheese still provides sufficient saltiness for most palates.

Storage and Serving

Storage: Keep in an airtight container in the refrigerator for up to 1 week. Do not freeze, as the texture will become grainy upon thawing.

Consistency Tip: If the dressing thickens too much in the refrigerator, allow it to sit at room temperature for 5-10 minutes before serving, or whisk in a small amount of water or milk to achieve desired consistency.

Serving Temperature: This dressing is best served chilled but not ice cold to fully appreciate the flavor complexities.
