Full Ingredients

Blue Cheese Sauce/Dressing Base

• 3/4 cup full-fat sour cream (180 g)
• 1/4 cup mayonnaise (60 g)
• 4 oz blue cheese, crumbled (115 g; about 1 cup loosely packed)
• 1 tbsp fresh lemon juice (15 ml)
• 1 tsp Worcestershire sauce (5 ml)
• 1/4 tsp kosher salt, plus more to taste
• 1/4 tsp freshly ground black pepper
• 2 tbsp finely snipped fresh chives

To Thin into a Pourable Dressing (Optional)

• 2–4 tbsp cold buttermilk or milk, as needed

Step-by-Step Instructions

Step 1: Choose and crumble the blue cheese

Select a flavorful blue cheese such as Roquefort, Gorgonzola, or Stilton. Crumble 4 oz (115 g) into small, pea- to bean-size bits so you get both speckles and a few small pockets in the finished sauce.

Step 2: Build the tangy base

In a medium bowl, whisk together 3/4 cup sour cream, 1/4 cup mayonnaise, 1 tbsp lemon juice, 1 tsp Worcestershire, 1/4 tsp kosher salt, and 1/4 tsp black pepper until completely smooth and creamy.

Step 3: Fold and mash the cheese for perfect texture

Fold in about 3/4 of the crumbled cheese so you keep nice chunky bits. With a fork, mash the remaining cheese into the base right in the bowl—this dissolves into the sauce for a rich, blue-forward flavor. For an extra-smooth finish, mash that portion of cheese with 2 tbsp of the base and microwave 15–20 seconds at 50% power, then whisk it back in. Do not overheat.

Step 4: Adjust thickness (sauce vs. dressing)

For a thick steakhouse-style sauce, leave as-is. For a pourable dressing, whisk in 2–4 tbsp cold buttermilk (or milk) a little at a time until it easily ribbons off a spoon. It should lightly coat a leaf of lettuce without clumping.

Step 5: Finish with chives and balance the flavors

Stir in 2 tbsp finely snipped chives. Taste and fine-tune: add more lemon for brightness, a pinch of salt if needed, or a few extra grinds of pepper for zip.

Step 6: Chill to marry flavors

Cover and refrigerate for 30 minutes. This rest helps the blue cheese bloom and the sauce thicken slightly. Stir before serving and transfer to your serving container—jar, small pitcher, or ramekin—for a neat presentation.

Pro Tips

• Pick your blue: milder (Gorgonzola dolce) for a gentler sauce; assertive (Roquefort or Stilton) for bigger blue flavor.
• Salt last—blue cheese and Worcestershire already bring salt. Taste after chilling before adjusting.
• Thickness control: chill to thicken; thin with buttermilk for dressing; if too loose, whisk in 1–2 tbsp sour cream or a few extra blue crumbles.
• Acid balance: lemon brightens the richness. If your blue is very salty, a few extra drops of lemon can bring the sauce into balance.
• If it breaks or looks grainy, whisk vigorously and add a spoonful of sour cream to bring it back together.

Variations

• Buttermilk Blue Dressing: Add 1 tsp Dijon mustard and 3–5 tbsp buttermilk to reach a classic, salad-ready pour.
• Buffalo Blue: Whisk in 1–2 tbsp hot sauce and a pinch of smoked paprika for wings and potatoes.
• Garlic-Herb: Add 1 small grated garlic clove (or 1/4 tsp garlic powder) and 1 tbsp minced parsley or dill.

Storage & Make-Ahead

Store in a sealed jar or container in the refrigerator for 4–6 days. Stir before each use. Flavor improves after the first day. Not suitable for freezing. If the sauce thickens too much in the fridge, loosen with a splash of milk or buttermilk and re-season. Check that your Worcestershire is gluten-free if needed.
