Prep: 15 minCook: 6 hrTotal: 6 hr 15 minServes: 6
Ingredients
- 2 lb boneless skinless chicken breasts, cut into 1-inch cubes
- 10 oz cremini mushrooms, sliced
- 4 oz shiitake mushrooms, caps sliced
- 3 medium carrots, peeled and sliced into 1/2-inch rounds
- 1 lb Yukon gold potatoes, diced into 3/4-inch cubes
- 1 medium yellow onion, finely chopped
- 4 cloves garlic, minced
- 2 1/2 cups low-sodium chicken broth
- 1 tbsp Dijon mustard
- 1 tsp dried thyme
- 1 tsp salt
- 1/2 tsp freshly cracked black pepper
- 3 tbsp cornstarch
- 3 tbsp cold water
- 1/2 cup heavy cream
- 2 tbsp fresh tarragon, chopped
Instructions
- Place the cubed chicken breasts, sliced cremini mushrooms, shiitake mushrooms, carrots, potatoes, yellow onion, and minced garlic into the bottom of a 6-quart crockpot.
- In a liquid measuring cup, whisk together the chicken broth, Dijon mustard, dried thyme, salt, and black pepper. Pour the broth mixture over the chicken and vegetables in the crockpot.
- Cover with the lid and cook on LOW for 5 to 6 hours (or on HIGH for 3 hours) until the chicken reaches an internal temperature of 165 F and the potatoes are fork-tender.
- In a small bowl, stir the cornstarch and cold water together until completely smooth. Stir the slurry into the stew.
- Cover and cook on HIGH for an additional 20 minutes until the stew liquid thickens.
- Turn off the heat, stir in the heavy cream and fresh tarragon, and let rest for 5 minutes before serving warm.
Tips
- For best texture, use Yukon gold potatoes as they hold their shape without becoming grainy in the slow cooker.
- Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat gently on the stovetop over medium-low heat.
- If you prefer a lighter sauce, half-and-half can be substituted for heavy cream added at the end of cooking.
