Tarragon Cream Sauce is a warm and luxurious condiment for chicken, fish, beef, and more. Quick and easy to make with only 8 ingredients, it instantly makes your everyday dinners feel gourmet!
Melt the butter in a small skillet over medium heat. Add the garlic and cook until fragrant, about 30 seconds.
Add the stock and tarragon to the skillet and simmer until reduced by half, 4-5 minutes.
Remove the skillet from heat and stir in the sour cream, dijon mustard and lemon juice. Season with salt and pepper to taste.
Notes
Tips and Tricks
To prevent the melted butter from browning or burning, heat the skillet over no higher than medium heat. Browned butter is sweet and nutty, which are the flavors we want in desserts and baked goods, not an herbaceous cream sauce.
Don’t rush the process! Allow the stock mixture to simmer and reduce over medium heat to concentrate the flavors and thicken the sauce.
Always taste your tarragon sauce before serving. The reduction process intensifies its flavors, so wait until the end to add any extra salt and pepper.
Storing
Store the leftover tarragon cream sauce in an airtight container in the refrigerator for up to 3 days. Freezing isn’t recommended because creamy sauces tend to separate after thawing.
To reheat, warm the sauce gently in a saucepan over low heat, stirring occasionally. You may need to add a splash of water or stock to bring it back to its smooth, silky consistency.
