Garlic Herb Powder Dressing
A silky, tangy creamy dressing made with mayonnaise and buttermilk, seasoned with garlic powder and a blend of dried herbs. Mix in minutes and use on salads, drizzled over roasted vegetables, or as a dip. The dressing emulsifies beautifully and gets more flavorful as it sits.
Steps
Before you start
- Have all ingredients at room temperature for the smoothest emulsion
- Use fresh dried herbs if possible—old ones lose potency
- Read through the whisking step so you don't over-whisk
Combine base ingredients
- Pour the mayonnaise and buttermilk into a medium bowl.
- Add the fresh lemon juice.
- Start with a whisk and gently combine these three ingredients with 8–10 slow strokes until they are mostly blended and smooth.
- The mixture should be creamy and pale; you're not whipping it, just incorporating the buttermilk evenly.

Ready when: Buttermilk is evenly blended with mayonnaise and lemon juice
Tip: Don't over-whisk yet—whipping too hard breaks the emulsion and can make the dressing thin and grainy.
Add powdered seasonings
- Sprinkle the garlic powder, onion powder, kosher salt, and black pepper over the mixture.
- Whisk gently for 10–12 strokes just until the powders are fully dissolved and no visible specks remain.
- The dressing should look smooth and uniform.

Ready when: No visible powder or grit; dressing is smooth
Tip: Powders dissolve faster in the acidic environment; if you see small specks, whisk a bit more, but stop as soon as they vanish.
Fold in dried herbs
- Add the dried dill, dried parsley, and dried chives (if using) to the dressing.
- Fold gently with the whisk using 6–8 slow strokes, just until the herbs are distributed throughout.
- You'll see small flecks of green and blue throughout the creamy base.

Ready when: Herbs evenly distributed throughout the dressing
Tip: Keep folding gentle so the herbs don't sink to the bottom; they should stay suspended for a pretty, flecked appearance.
Rest and set
- Transfer the dressing to a clean jar or container.
- Cover and let it rest at room temperature for 15 minutes.
- The flavors will marry, the garlic and herbs will bloom slightly, and the dressing will thicken just a bit as it sits.
- Stir once before serving.

Ready when: Dressing is smooth, well-blended, and has a pleasant herb aroma
Tip: Resting is not optional—it lets the dried herbs rehydrate and the garlic powder fully dissolve, making a more cohesive, flavorful dressing.

Tips
- Taste as you go: after the 15-minute rest, taste the dressing and adjust salt, garlic, or lemon juice to your preference. It's easier to add more seasoning than to fix oversalting.
- For a thinner, pourable dressing, whisk in 1–2 tablespoons of buttermilk or milk. For a thicker dip consistency, add 1 tablespoon more mayonnaise.
- Dried herbs are key to this recipe's quick assembly. If you only have fresh herbs on hand, finely mince them and use 3 times the dried amount (so 3 tsp dill, 3 tsp parsley), but add them just before serving so they don't turn dark.
- This dressing pairs beautifully with crisp iceberg or romaine salads, roasted potatoes, hard-boiled eggs, and grilled chicken. It also doubles as a dip for crudités or a spread for sandwiches.
Make ahead
Dressing can be made up to 3 days ahead; see storage for details.
Storage & reheating
Room temperature: up to 2 hours before serving. Refrigerator: store in a covered jar or airtight container for up to 5 days. The flavors deepen slightly after 1 day. Freezer: not recommended—the emulsion may separate upon thawing. To serve chilled, remove from the fridge 10 minutes before using so it reaches a pourable consistency; if it thickens too much, whisk in 1 tablespoon of buttermilk to loosen.
Substitutions
- mayonnaise → Greek yogurt (plain, full-fat). Use 1 cup (240 ml / 240 g) Greek yogurt and reduce buttermilk to 2 tablespoons (30 ml) to keep the consistency similar. The dressing will be slightly tangier and thinner than the original.
- buttermilk → Sour cream thinned with water or milk. Use ¼ cup (60 ml) sour cream mixed with 1–2 tablespoons water. Adjust water to reach the desired consistency. Flavor will be richer and more sour.
- dried dill → Dried tarragon or dried basil. Use 1 teaspoon (1 g) of either herb. Tarragon brings anise notes; basil adds warmth. The character will shift slightly but remain herbaceous.
- fresh lemon juice → White wine vinegar or apple cider vinegar. Use 1½ tablespoons (22 ml) vinegar instead of 2 tablespoons lemon juice. The dressing will be sharper and more tangy.
