Creating Chicken Puttanesca is straightforward if you follow these simple steps:

1. Prepare the Chicken: Season the chicken thighs with salt and pepper on both sides.
2. Heat the Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Sear the Chicken: Add the chicken thighs to the skillet and cook for about 5-6 minutes on each side, or until browned and cooked through. Remove the chicken from the skillet and set aside.
4. Sauté Garlic: In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant.
5. Add Tomatoes and Seasonings: Pour in the diced tomatoes, olives, capers, red pepper flakes, and oregano. Stir to combine.
6. Simmer the Sauce: Allow the sauce to simmer for about 5 minutes, letting the flavors meld together.
7. Return Chicken to Skillet: Add the seared chicken thighs back to the skillet, nestling them into the sauce. Cook for an additional 5 minutes to heat through.
8. Garnish and Serve: Remove from heat and garnish with freshly chopped parsley before serving.

Following these steps will lead you to a delicious Chicken Puttanesca that is sure to impress!
