Ingredients
For the Chicken
| Ingredient | Quantity |
| Boneless or bone-in chicken thighs, skinless | 2½–3 lb (1.1–1.3 kg) |
| Kosher salt | 1 teaspoon |
| Freshly ground black pepper | ½ teaspoon |
| Olive oil or melted butter, optional | 1 tablespoon |
For the Creamy Tarragon White Wine Sauce
| Ingredient | Quantity |
| Dry white wine, such as Sauvignon Blanc or Pinot Grigio | ¾ cup (180 ml) |
| Heavy cream | ¾ cup (180 ml) |
| Dijon mustard | 2 tablespoons |
| Shallots, finely chopped | 2 medium |
| Fresh tarragon, chopped | 2 tablespoons |
| Dried tarragon, if using instead of fresh | 2 teaspoons |
Ingredient note: Use either fresh or dried tarragon, not both. Choose a dry white wine you enjoy drinking. For an alcohol-free version, replace the wine with low-sodium chicken broth and add 1–2 teaspoons of lemon juice for brightness.
Step-by-Step Instructions
Step 1: Prepare the Slow Cooker
Lightly grease the inside of a 5- to 6-quart slow cooker with olive oil or melted butter, if desired.
Pat the chicken thighs dry with paper towels. Season both sides evenly with kosher salt and freshly ground black pepper.
Arrange the chicken in a single layer in the bottom of the slow cooker whenever possible.
Step 2: Make the Creamy Tarragon Sauce
In a medium bowl, whisk together the dry white wine, heavy cream, Dijon mustard, chopped shallots, and fresh or dried tarragon.
Whisk until the mustard is evenly incorporated and the sauce looks smooth. The shallots and tarragon will add aromatic flavor as the chicken cooks.
Step 3: Combine the Ingredients
Pour the creamy white wine mixture evenly over the chicken thighs.
Use a spoon to distribute the shallots and herbs throughout the slow cooker. Cover with the lid.
Step 4: Slow Cook the Chicken
Cook according to your preferred setting:
- LOW: 5–6 hours.
- HIGH: 3–4 hours.
Cooking times can vary depending on the size of the chicken thighs and the slow cooker model. The chicken is ready when it is tender and reaches an internal temperature of 165°F (74°C), measured with a food thermometer at the thickest part.
Avoid lifting the lid unnecessarily during cooking, as this releases heat and can extend the cooking time.
Step 5: Finish the Creamy Sauce
Once the chicken is cooked, gently stir the sauce around the chicken to combine the flavors.
If the sauce is thinner than you prefer, transfer it to a small saucepan and simmer it gently until reduced to your desired consistency. Alternatively, stir in a small cornstarch slurry made with 1 teaspoon of cornstarch and 1 tablespoon of cold water, then heat until thickened.
If using the slow cooker to finish the sauce, add any thickener and cook briefly according to your appliance’s instructions. Avoid boiling the cream sauce vigorously, as this can affect its texture.
Taste and adjust the seasoning with additional salt, pepper, or a little lemon juice if needed.
Step 6: Serve and Enjoy
Transfer the chicken thighs to serving plates and spoon the creamy tarragon white wine sauce generously over the top.
Garnish with a little extra chopped fresh tarragon, if desired. Serve immediately with mashed potatoes, fluffy rice, buttered noodles, or roasted vegetables.
Best Tips for Perfect Slow Cooker Chicken
For the most flavorful results, use chicken thighs because they stay tender and juicy during slow cooking. Arrange the chicken in a single layer when possible so it cooks evenly. Measure the tarragon carefully because its distinctive anise-like flavor can become overpowering if too much is added. For a richer sauce, use heavy cream rather than milk, and finish the sauce separately if you want a thicker consistency.
Best Ingredient Options
Chicken thighs are ideal for this recipe, but boneless, skinless chicken breasts can also work. Check them earlier because they may cook faster and dry out if left in the slow cooker too long. Fresh tarragon offers the brightest herbal flavor, while dried tarragon is a convenient pantry alternative. Shallots provide a delicate sweetness, but finely chopped yellow onion can be substituted. For a lighter sauce, use half-and-half, keeping in mind that the sauce will be less rich and may be more prone to separating.
Recipe Variations
For a mushroom version, add sliced cremini or button mushrooms before cooking. To create a lemon-tarragon variation, finish the sauce with a teaspoon or two of fresh lemon juice. For extra garlic flavor, add one or two minced garlic cloves to the sauce. If you prefer an alcohol-free recipe, use chicken broth in place of white wine. You can also add baby spinach near the end of cooking for a touch of color and extra vegetables.
What to Serve With Creamy Tarragon Chicken
Creamy tarragon chicken pairs wonderfully with buttery mashed potatoes because they absorb the rich white wine sauce. Steamed rice and egg noodles are also excellent choices. For a balanced dinner, serve it with roasted carrots, green beans, asparagus, or a crisp green salad. Crusty bread is another delicious option for soaking up every last spoonful of the creamy sauce.
Make-Ahead Instructions
To save time, chop the shallots and tarragon and measure the sauce ingredients a day ahead. Store the prepared ingredients separately in airtight containers in the refrigerator.
For the best food safety, keep raw chicken refrigerated and separate from ready-to-eat ingredients. Assemble the recipe shortly before cooking rather than leaving raw chicken and cream sitting in the slow cooker insert at room temperature.
Storage Instructions
Allow leftovers to cool slightly, then transfer the chicken and sauce to shallow, airtight containers and refrigerate within two hours of cooking.
Store in the refrigerator for up to 3–4 days. Keep the chicken covered with sauce to help maintain moisture.
For food safety, reheat leftovers to an internal temperature of 165°F (74°C).
Reheating Instructions
On the stovetop: Place the chicken and sauce in a covered saucepan. Heat gently over low to medium-low heat, stirring the sauce occasionally, until the chicken is thoroughly heated.
In the microwave: Place an individual portion in a microwave-safe dish and cover loosely. Heat in short intervals, turning or stirring as needed, until evenly hot.
Add a splash of chicken broth or cream if the sauce has thickened too much during storage. Avoid prolonged high heat to help prevent the cream sauce from separating.
Freezing Instructions
Cream-based sauces can change texture when frozen, so freezing this recipe is possible but may produce a slightly grainy or separated sauce after thawing.
For the best quality, freeze the cooked chicken separately from the sauce when practical. Store in freezer-safe airtight containers for up to 2 months for best results.
Thaw overnight in the refrigerator. Reheat gently, stirring the sauce well. If needed, whisk in a small splash of cream or broth to help restore its consistency.
Common Mistakes to Avoid
Avoid adding too much tarragon, as its strong herbal flavor can overwhelm the creamy sauce. Do not use sweet wine unless you specifically want a sweeter result. Overcooking the chicken can make it dry, especially when using boneless chicken breasts. Avoid vigorous boiling when thickening the sauce, because high heat can cause the cream to separate. Finally, always check the chicken’s internal temperature rather than relying on cooking time alone.

Frequently Asked Questions
Can I use chicken breasts instead of chicken thighs?
Yes. Boneless chicken breasts can be used, but they tend to cook faster and can dry out more easily. Check the internal temperature early and remove them once they reach 165°F (74°C).
Can I make this recipe without white wine?
Absolutely. Substitute low-sodium chicken broth for the white wine. A small amount of lemon juice added toward the end can provide a similar touch of acidity.
Can I use dried tarragon?
Yes. Use 2 teaspoons of dried tarragon in place of 2 tablespoons of fresh tarragon. Dried herbs have a more concentrated flavor, so measure carefully.
Why is my creamy sauce too thin?
Slow cookers retain moisture, which can leave sauces thinner than expected. Transfer the sauce to a saucepan and simmer gently to reduce it, or add a small cornstarch slurry and heat until thickened.
Can I put raw chicken directly into the slow cooker?
Yes, provided the chicken is properly refrigerated before preparation and the slow cooker is used according to its manufacturer’s instructions. Arrange the chicken evenly and ensure it reaches an internal temperature of 165°F (74°C).
Can I prepare this recipe the night before?
You can prepare and refrigerate the chopped shallots, herbs, and measured sauce ingredients in advance. For food safety, assemble the raw chicken and sauce shortly before starting the slow cooker.
What is the best wine for creamy tarragon chicken?
A dry white wine such as Sauvignon Blanc or Pinot Grigio works well. Avoid heavily sweet wines, which can change the flavor of the sauce.
Can I add vegetables to the slow cooker?
Yes. Sliced mushrooms and carrots can be added at the beginning. More delicate vegetables, such as spinach, are best stirred in near the end of cooking to preserve their color and texture.
