1-First Step: Mise en Place and Prep Chicken Pat 4 boneless chicken breasts dry with paper towels. Season both sides with salt and pepper. Chop 1 onion and mince 2 garlic cloves. Chop 2 tbsp fresh tarragon, reserving some for garnish. Measure out 1 cup chicken broth, ½ cup white wine, 1 cup heavy cream, and 2 tbsp Dijon mustard. This setup keeps your quick tarragon chicken recipe flowing smoothly. For dietary tweaks, use thighs for juicier meat or plant-based cutlets for vegan.

2-Second Step: Sear the Chicken Heat 2 tbsp olive oil in a skillet over medium-high heat. Add chicken breasts, searing 5 minutes per side until golden brown. This step builds flavor via Maillard reaction. Remove chicken to a plate; it will finish cooking later. Juices released add richness to the sauce. Tip: Press chicken gently for even browning. Adapt for low-fat by using cooking spray.

3-Third Step: Sauté Aromatics In the same skillet, lower heat to medium. Add chopped onion and cook 3 minutes until softened. Stir in minced garlic for 1 minute to release fragrance without burning. This base anchors the chicken with tarragon cream sauce. Scrape up browned bits for depth. For gluten-free, no changes needed.

4-Fourth Step: Deglaze and Build Sauce Base Pour in ½ cup dry white wine, scraping pan bits. Simmer 2 minutes to reduce alcohol. Add 1 cup chicken broth, 2 tbsp Dijon mustard, and 1.5 tbsp chopped tarragon. Bring to simmer for 5 minutes, letting flavors meld. Mustard emulsifies for smoothness. Wine sub: extra broth for alcohol-free. Stir occasionally.

5-Fifth Step: Add Cream and Return Chicken Stir in 1 cup heavy cream gently to avoid curdling; do not boil. Nestle chicken back in sauce, spooning some over top. Cover and simmer on low 10 minutes until chicken reaches 165°F internal temperature. Sauce thickens naturally. For lighter version, use half-and-half here. Test doneness with thermometer.

6-Final Step: Finishing Touches and Serving Remove from heat. Let rest 2 minutes for juiciness. Slice chicken, plate with sauce spooned over. Garnish with extra tarragon and optional lemon squeeze. Serve over rice, pasta, mashed potatoes, or egg noodles to soak up sauce. Pairs with green beans for complete meal. This method ensures moist chicken every time in your creamy French chicken tarragon.
