Ingredients

• 1.5 lbs bone-in, skin-on chicken thighs
• 2 tbsp olive oil
• 1, diced large onion
• 3, minced garlic cloves
• 8 oz, sliced cremini mushrooms
• 2, peeled and chopped into 1-inch pieces carrots
• 2, peeled and chopped into 1-inch pieces parsnips
• 4 cups chicken stock
• 2 fresh thyme sprigs
• 1 bay leaf
• 1 tsp salt
• 1/2 tsp black pepper
• 2 tbsp (optional for thickening) all-purpose flour

Instructions

1. Step 1: Heat 2 tbsp olive oil in a large Dutch oven over medium-high heat. Season 1.5 lbs bone-in, skin-on chicken thighs with 1 tsp salt and 1/2 tsp black pepper, then sear for 4-5 minutes per side until golden brown; remove and set aside.
2. Step 2: Add 1 diced onion and 3 minced garlic cloves to the pot and cook for 3 minutes until softened. Stir in 8 oz sliced cremini mushrooms and cook for 2 minutes until mushrooms release moisture and begin to brown.
3. Step 3: Return 1.5 lbs chicken thighs to the pot, add 2 chopped carrots and 2 chopped parsnips, pour in 4 cups chicken stock, and add 2 fresh thyme sprigs and 1 bay leaf. Bring to a gentle simmer, then reduce heat to low, cover, and cook for 45 minutes until chicken is tender and vegetables are fork-tender.
4. Step 4: Remove chicken and vegetables from the pot, strain the broth into a bowl (discard thyme and bay leaf), and if desired, whisk 2 tbsp all-purpose flour with 2 tbsp cold water to make a slurry. Stir the slurry into the strained broth and simmer for 2 minutes until thickened. Return chicken and vegetables to the pot and heat through for 1 minute.
