Creating Cozy One-Pot Chicken Marengo can be a breeze if you follow these simple steps:

1. Heat the Oil: In a large pot or Dutch oven, heat the olive oil over medium-high heat.
2. Brown the Chicken: Season the chicken thighs with salt and pepper. Add them to the pot, skin side down, and brown for about 5-7 minutes. Flip and brown the other side for another 5 minutes. Remove the chicken and set aside.
3. Sauté the Vegetables: In the same pot, add the chopped onion, garlic, bell pepper, and carrots. Sauté for 5-6 minutes until softened.
4. Add Tomatoes and Broth: Pour in the diced tomatoes with their juices, chicken broth, and white wine. Stir to combine.
5. Season: Add thyme and bay leaf to the mixture. Stir, then return the chicken to the pot, nestling it into the sauce.
6. Simmer: Bring to a gentle simmer, cover, and reduce the heat to low. Cook for about 30 minutes, or until the chicken is cooked through and tender.
7. Garnish: Once cooked, remove the bay leaf and discard. Sprinkle fresh parsley over the top for a burst of color.
8. Serve: Serve warm, enjoying the rich flavors that meld beautifully in this one-pot dish.

These steps will guide you in creating this cozy chicken dish effortlessly.
