Creating Easy One Pan Italian Chicken In Tomato Sauce can be a hassle-free process if you follow these step-by-step instructions:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
2. Sear the Chicken: Heat olive oil in a large oven-safe skillet over medium heat. Season chicken thighs with salt and pepper. Place them skin-side down in the skillet and sear until browned (about 5-7 minutes). Flip and sear the other side for another 5 minutes. Remove the chicken and set it aside.
3. Sauté Onions and Garlic: In the same skillet, add the diced onion and sauté until translucent (about 3-4 minutes). Stir in the minced garlic and cook for an additional minute until fragrant.
4. Add Herbs and Tomatoes: Sprinkle oregano and basil over the onion mixture. Then, add the crushed tomatoes and chicken broth, stirring to combine.
5. Return Chicken to Skillet: Place the seared chicken thighs back into the pan, skin-side up, ensuring they are nestled in the tomato sauce.
6. Bake: Transfer the skillet to the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
7. Garnish and Serve: Once done, remove from the oven. Garnish with fresh basil and sprinkle with grated Parmesan cheese if desired.

These simple steps will guide you seamlessly in making this amazing dish that can truly redefine your dinner table.
