A bright, herbaceous vinaigrette balanced with Dijon, fresh lemon, and orange blossom honey. Finished with finely chopped tarragon for an anise-tinged lift.
Why You'll Love Lemon Mustard Tarragon Vinaigrette
This is the dressing that makes a simple salad feel composed. The mustard builds body, the lemon keeps it sharp, and the tarragon brings a soft anise note that pairs with just about anything green. It comes together in under five minutes and holds in the fridge - ready to pour over roasted chicken, grilled fish, or a pile of butter lettuce. One of those quiet workhorses that elevates whatever it touches.
Tips and Tricks
- Whisk the mustard into the acid before adding oil - it's the emulsifier that keeps everything stable.
- Pour the oil in a slow, steady stream while whisking for a thicker, creamier emulsion.
- Use fresh tarragon, not dried - the flavor is a different animal.
- Taste and adjust at the end. Lemon varies in acidity, so trust your palate.
Variations
- Swap tarragon for fresh dill or chervil for a different herbal profile.
- Add a small minced shallot for body and bite.
- Stir in a spoon of crème fraîche for a creamy version.
Substitutions
- Orange blossom honey → regular honey or maple syrup
- Dijon mustard → whole grain mustard for more texture
- Olive oil → a neutral oil like grapeseed for a milder finish
Best served with
- Butter lettuce or little gem salads
- Grilled asparagus or blanched green beans
- Roasted chicken or seared white fish
How to Store Leftovers
Store in an airtight jar in the fridge for up to 1 week. The oil may solidify when cold - let it come to room temperature and shake well before using.
Common Questions
Can I make this ahead of time?
Yes - it holds in the fridge for up to a week. Shake or whisk before each use to re-emulsify.
Can I use dried tarragon?
Not recommended. Fresh tarragon is essential for the clean anise note this vinaigrette is built on.
Why won't my dressing emulsify?
Pour the oil in slowly while whisking constantly, and make sure the mustard is fully incorporated first - it's what stabilizes the emulsion.
