Now, let’s walk through the steps to make this incredible Chicken Pizzaiola:

1. Heat Olive Oil: In a large skillet, heat the olive oil over medium heat.
2. Cook Chicken: Season the chicken thighs with salt and pepper. Add them to the skillet and sear until browned, about 5-7 minutes per side. Remove the chicken from the skillet and set aside.
3. Sauté Vegetables: In the same skillet, add the sliced onions and bell pepper. Sauté until the onions are translucent and the peppers are tender, around 5 minutes.
4. Add Garlic: Add the minced garlic to the skillet and cook for an additional minute until fragrant.
5. Create the Sauce: Stir in the diced tomatoes, tomato paste, oregano, and basil. Mix well, allowing it to simmer for 5 minutes to thicken slightly.
6. Return Chicken: Carefully place the seared chicken back into the skillet, ensuring they’re coated with the sauce.
7. Simmer: Cover the skillet and let everything simmer for about 15-20 minutes, or until the chicken is cooked through.
8. Serve: Once the chicken is cooked, taste the sauce and adjust seasoning if necessary. Remove from heat and garnish with fresh parsley or basil before serving.

Each of these steps is straightforward, ensuring you create a delightful dish without any fuss.
