This slow cooker method transforms chicken into tender, herb-infused perfection with minimal effort. The tarragon infuses every bite with its distinctive anise-like aroma.

By letting the slow cooker work its magic, you’ll achieve fall-apart texture and rich flavor without constant attention. The result is a dish that tastes like it simmered all day.

Ingredients for Tarragon Chicken Slow Cooker

Fresh herbs and simple pantry staples create this herb-infused slow cooker masterpiece with ease.

The tarragon is non-negotiable here—fresh is essential for that distinctive anise-like aroma mentioned in the introduction. Source it from Whole Foods or a well-stocked Kroger; dried tarragon lacks the necessary potency. For the chicken, thighs outperform breasts in slow cooking, remaining juicy while absorbing the herb flavors. If using breasts, reduce cooking time by 30 minutes to prevent dryness.

No white wine? Substitute dry vermouth or additional chicken stock with a splash of apple cider vinegar. Heavy cream can be swapped for full-fat coconut milk (though the flavor profile will shift). For the mustard, whole-grain Dijon adds texture if you prefer it. The flour thickens the sauce—cornstarch at half the amount works as a gluten-free alternative.

This dish tastes even better the next day as flavors meld. Store leftovers in an airtight container for up to 4 days in the refrigerator or freeze for 3 months. Reheat gently on the stove with a splash of stock to restore creaminess.

Step-by-Step Instructions for Tarragon Chicken in the Slow Cooker

This hands-off method guarantees fall-off-the-bone chicken with a velvety herb sauce.

Step 1: Sear and Season the Chicken Thighs

Pat the 2 lb boneless, skinless chicken thighs completely dry with paper towels. This step ensures a proper sear and prevents steaming in the slow cooker. Season both sides evenly with the 1.5 tsp kosher salt and 0.5 tsp freshly ground black pepper.

Heat the 1 tbsp olive oil in a large skillet over medium-high heat. Working in batches to avoid crowding, sear the chicken thighs for 3-4 minutes per side until deep golden brown and easily releases from the pan. Transfer to the slow cooker insert.

Step 2: Build the Aromatic Base

In the same skillet, reduce heat to medium and add the 1 tbsp unsalted butter. Once melted, add the finely diced yellow onion and cook for 4-5 minutes until softened and translucent. Stir in the minced 4 cloves garlic cloves and cook for 30 seconds until fragrant.

Sprinkle the 2 tbsp all-purpose flour over the onion mixture and cook for 1 minute, stirring constantly. This creates a roux that will thicken the final sauce. Deglaze with the 0.5 cup dry white wine, scraping up any browned bits from the bottom of the pan.

Step 3: Slow Cook with Herbs and Liquid

Pour the onion-wine mixture over the chicken in the slow cooker. Add the 0.25 cup finely chopped fresh tarragon leaves, 0.5 cup chicken stock, 2 tbsp Dijon mustard, and 1 tbsp fresh lemon juice. Stir gently to combine all ingredients.

Cover and cook on low for 4-5 hours or high for 2-3 hours. The dish is ready when the chicken reaches 165°F internally and shreds easily with a fork. The tarragon will infuse the broth with its distinctive anise-like aroma.

Step 4: Finish with Cream for Luxurious Sauce

Transfer the chicken to a serving platter and tent with foil to keep warm. Pour the cooking liquid through a fine-mesh strainer into a saucepan to remove any solids. Bring to a simmer over medium heat.

Gradually whisk in the 0.5 cup heavy cream and continue simmering for 3-4 minutes until the sauce thickens enough to coat the back of a spoon. Pour the finished sauce over the chicken and garnish with additional fresh tarragon leaves if desired.

Essential Equipment for This Recipe

Slow Cooker Essentials

I swear by my 6-quart programmable slow cooker from Crock-Pot—it’s the perfect size for this recipe and offers precise temperature control. Look for one with a removable ceramic insert for easy cleanup and serving. 💡

Searing Skillet

A heavy 12-inch stainless steel skillet is my go-to for searing chicken. All-Clad makes excellent ones that distribute heat evenly. Avoid nonstick—you need those browned bits for flavor in the sauce.

Fine-Mesh Strainer

Straining the sauce requires a fine-mesh strainer to remove solids. I use a 5-inch strainer from OXO—it fits perfectly over my saucepan and the handle stays cool. This ensures a silky texture.

Saucepan for Finishing

For reducing the sauce, a 2-quart heavy-bottomed saucepan prevents scorching. Cuisinart MultiClad is my choice—it responds quickly to temperature changes. The cream needs gentle heat to avoid curdling.

Instant-Read Thermometer

Don’t guess when chicken is done—use an instant-read thermometer. I trust my ThermoWorks ThermoPop for accuracy within 2°F. Check multiple pieces to ensure all reach 165°F. 🌡️

Wooden Spoon

A wooden spoon is perfect for stirring the roux and deglazing the pan. It won’t scratch your cookware and handles high heat well. I keep one dedicated to my skillet for just this kind of cooking.
