Ingredients

Instructions

  1. Step 1: Season 4 bone-in, skin-on chicken thighs with 1/2 tsp salt and 1/4 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering, then sear the chicken thighs for 3-4 minutes per side until golden brown. Transfer to a slow cooker.
  2. Step 2: In the same skillet, cook 1 diced medium onion over medium heat for 2 minutes until translucent, then add 3 minced garlic cloves and cook for 30 seconds until fragrant. Transfer to the slow cooker.
  3. Step 3: Whisk 1/4 cup Dijon mustard, 1/4 cup honey, and 1 tbsp apple cider vinegar in a small bowl until smooth, then pour over the chicken in the slow cooker.
  4. Step 4: Add 4 medium carrots (peeled and cut into 1-inch pieces), 4 medium parsnips (peeled and cut into 1-inch pieces), 4 medium potatoes (peeled and cut into 1-inch cubes), 1 tsp dried thyme, and 1 bay leaf to the slow cooker. Stir gently to combine.
  5. Step 5: Secure the lid and cook on low for 6 hours (360 minutes) until the chicken is fork-tender and vegetables are easily pierced with a fork.
