Step 1: Prepare the Chicken: Pat the chicken breasts dry with paper towels and season generously with salt and freshly ground black pepper. Proper seasoning at this stage enhances the overall flavor.
Step 2: Sear the Chicken: Heat the olive oil in a large skillet over medium-high heat. Add the chicken breasts and sear for 4-5 minutes per side, until golden brown. The searing creates a flavorful crust, enhancing the dish's complexity. Remove the chicken from the skillet and set aside.
Step 3: Saut the Shallots: Reduce the heat to medium and add the chopped shallots to the skillet. Saut for 2-3 minutes, until softened and fragrant. Stir frequently to prevent burning, allowing the shallots to release their aromatic oils.
Step 4: Deglaze with White Wine: Pour in the white wine and deglaze the skillet, scraping up any browned bits from the bottom. Allow the wine to reduce by half, concentrating its flavors and creating a rich base for the sauce.
Step 5: Add Chicken Broth and Cream: Pour in the chicken broth and bring to a simmer. Reduce the heat to low and stir in the heavy cream. Simmer gently for 5-7 minutes, allowing the sauce to thicken slightly. Simmer gently for 5-7 minutes, allowing the sauce to thicken slightly.
Step 6: Return Chicken to the Skillet: Return the seared chicken breasts to the skillet, nestling them into the creamy sauce. Cover the skillet and simmer for 10-12 minutes, or until the chicken is cooked through and reaches an internal temperature of 165F (74C). Use of meat thermometer ensures food safety.
Step 7: Finish the Sauce: Remove the chicken from the skillet and set aside. Stir in the fresh tarragon, butter, and lemon juice into the sauce. Season with salt and pepper to taste. This final step elevates the sauce with fresh flavors and a touch of brightness.
Step 8: Serve: Spoon the creamy tarragon sauce over the chicken breasts and serve immediately. Garnish with additional fresh tarragon, if desired.
For a richer flavor, use bone-in, skin-on chicken thighs. If you don't have white wine, chicken broth can be substituted. For dairy-free option, use coconut cream.
