This Creamy Lemon Tarragon Sauce recipe is easy and made with sour cream and Dijon mustard. Great for dipping salmon, chicken, or steak!
One of my favorite ways to use this underestimated herb is added to this Creamy Tarragon Sauce. It’s a great all-purpose dipping sauce made with sour cream, lemon juice, and Dijon mustard.
I’m a huge fan of culinary herbs and use things like basil and cilantro all the time. These well-known herbs are often added to popular dishes like pizza, pasta, and tacos.
One culinary herb that tends to fly under the radar is tarragon. It’s unfortunate because tarragon has such a great bright flavor that’s absolutely perfect in light spring and summer dishes.
Tarragon is hugely popular in France – It’s known as the ‘king of herbs’ in that country and used all across the culinary spectrum but that isn’t the case here in the United States and certainly not in the Midwest.

👩🍳 Instructions
Step 1: Combine the Base
In a medium mixing bowl, add 1 cup of fat-free sour cream and ¼ cup of Dijon mustard. Whisk them together until completely smooth and combined.
Step 2: Add the Citrus and Spices
Pour in the fresh lemon juice, then add the garlic powder, kosher salt, and black pepper. Whisk gently until the spices are fully incorporated into the creamy base.
Step 3: Fold in the Tarragon
Gently stir in the finely chopped fresh French tarragon (or dried tarragon). This herb gives the sauce its signature French flair with a subtle, aromatic hint of licorice.
Step 4: Chill and Serve
For the best flavor, cover the bowl and let it chill in the refrigerator for at least 30 minutes before serving. This allows the tarragon and garlic to fully infuse into the cream.
