Creating Easy One Pan Italian Chicken In Tomato Sauce is effortless when you follow these steps:

1. Heat the Pan: In a large skillet, heat the olive oil over medium heat.
2. Sear the Chicken: Season the chicken breasts with salt and pepper. Add them to the skillet and sear for 5-7 minutes on each side until golden brown. Remove the chicken and set aside.
3. Sauté the Vegetables: In the same pan, add the diced onion and sliced bell peppers. Cook for 3-4 minutes until softened. Add the minced garlic and cook for an additional minute until fragrant.
4. Add Tomatoes and Spices: Pour in the diced tomatoes along with their juice. Stir in the dried oregano, dried basil, and red pepper flakes if using. Season with salt and pepper to taste.
5. Return the Chicken: Place the seared chicken breasts back into the skillet, nestling them into the tomato sauce mixture.
6. Simmer: Cover the skillet and let it simmer for about 15 minutes. The chicken should be cooked through and the flavors melded together beautifully.
7. Garnish and Serve: Once cooked, remove from heat. Garnish with fresh basil leaves and serve with grated Parmesan cheese, if desired.

These simple steps will guide you in creating an incredible dish that is full of flavor!
