1 pound carrots, cut into 1 1/4-inch pieces
1 pound (3-4 medium) yellow-fleshed potatoes
1 1/4-inch-wide wedges
2 pounds boneless, skinless chicken thighs
1 14-ounce can reduced-sodium chicken broth
1/3 cup dry white wine
4 cloves garlic, minced
3/4 teaspoon salt
1 15-ounce can artichoke hearts
1 large egg
2 large egg yolks
1/3 cup lemon juice
1/3 cup chopped fresh dill
Freshly ground pepper
1. Spread carrots and potatoes over the bottom and up the sides of a 4-quart or larger slow cooker. Arrange chicken on top of the vegetables. Bring broth, wine, garlic and salt to a simmer in a medium saucepan over medium-high heat. Pour over the chicken and vegetables. Cover and cook until the chicken is cooked through and vegetables are tender, 2 1/2 to 3 hours on high or 4 to 4 1/2 hours on low.
2. Add artichokes to the slow cooker, cover and cook on high for 5 minutes. Meanwhile, whisk egg, egg yolks and lemon juice in a medium bowl.
3. Transfer the chicken and vegetables to a serving bowl using a slotted spoon. Cover and keep warm. Ladle about 1/2 cup of the cooking liquid into the egg mixture. Whisk until smooth. Whisk the egg mixture into the remaining cooking liquid in the slow cooker. Cover and cook, whisking 2 or 3 times, until slightly thickened and sauce reaches 160°F on an instant-read thermometer, 15 to 20 minutes. Stir in dill and pepper. Pour the sauce over the chicken and vegetables and serve.
