Making Cozy One-Pot Chicken Marengo is simple if you follow these easy steps:

1. Heat the Oil: In a large pot or Dutch oven, heat the olive oil over medium-high heat.
2. Sear the Chicken: Season the chicken thighs with salt and pepper. Place them skin-side down in the pot and sear for about 5-7 minutes until the skin is golden brown. Flip and sear the other side for another 5 minutes. Remove the chicken and set aside.
3. Sauté the Onions and Garlic: In the same pot, add the diced onion. Sauté for about 3-4 minutes until translucent. Add minced garlic and cook for an additional minute until fragrant.
4. Add Tomatoes: Stir in the halved cherry tomatoes and cook for about 5 minutes until they soften.
5. Add Broth and Herbs: Pour in the chicken broth, and add dried oregano, thyme, and bay leaf. Stir well to combine.
6. Return Chicken to Pot: Place the seared chicken thighs back into the pot, skin-side up. Ensure they are partially submerged in the liquid.
7. Simmer: Cover the pot and reduce the heat to low. Let it simmer for about 30-35 minutes, or until the chicken is cooked through and tender.
8. Adjust Seasoning: Taste and adjust the seasoning with salt and pepper as needed.
9. Garnish: Remove the bay leaf and sprinkle fresh basil over the dish just before serving.

These steps will guide you in creating this comforting meal effortlessly.
