Adapt it for your goals.
Vegan
Swap butter for olive oil, heavy cream for full-fat coconut milk, and use a gluten-free flour blend. You'll lose the subtle dairy richness, but the coconut adds a new layer of sweetness that pairs well with the tarragon.
Gluten FreeGluten-Free
Replace the all-purpose flour with an equal amount of rice flour or a gluten-free all-purpose blend. The sauce will still thicken but may be slightly less glossy.
Extra HerbyExtra Herby
Add 1 tablespoon of fresh chopped chives or parsley along with the tarragon for a brighter, more complex herb profile—great with fish or chicken.
Wine TwistWine Twist
After sautéing the mushrooms, deglaze the pan with 1/4 cup of dry white wine before adding the shallot. This adds acidity and depth, making the sauce even more luxurious.
