  • Mince ¼ cup French tarragon.
  • Add 1 cup sour cream, ¼ cup Dijon mustard, ¼ cup lemon juice, ½ tsp. garlic powder, and ¼ tsp. each of kosher salt and pepper to a small bowl. Stir until completely combined using a small whisk or a fork.
  • Add the chopped tarragon and stir until combined.
  • Feel free to serve right away or store in the fridge for a few hours to allow the flavors to develop.
  • To Serve: Serve as a dipping sauce for fish, salmon, lobster, chicken, steak, grilled, roasted or raw vegetables or as a sandwich spread.


Feel free to sub dried tarragon for fresh tarragon. Start with 2 Tbsp. dried tarragon and add more if desired.
You can thin the sauce out by adding more lemon juice or water if you prefer a thinner consistency.
If you prefer more sweetness you can use honey mustard and if you like more spice you can use a spicy mustard or horseradish mustard.
