Creating Chicken Scarpariello is a straightforward process that yields fantastic results. Follow these simple steps:

1. Marinate Chicken: If desired, marinate the chicken thighs in a mixture of olive oil, garlic, oregano, red pepper flakes, salt, and pepper for at least 30 minutes.
2. Heat Oil: In a large skillet or Dutch oven, heat olive oil over medium-high heat.
3. Brown Chicken: Add the chicken thighs, skin-side down, and cook until golden brown, about 5-7 minutes. Flip and cook for another 5-7 minutes. Remove and set aside.
4. Sauté Vegetables: In the same skillet, add the sliced onion and peppers. Sauté until softened, around 4-5 minutes. Add the minced garlic and cook for an additional minute.
5. Deglaze the Pan: Pour in the white wine to deglaze the pan, scraping up any browned bits. Allow to simmer for 2-3 minutes.
6. Combine Ingredients: Return the chicken thighs to the pan, along with the diced potatoes. Add the chicken broth, red wine vinegar, and additional salt and pepper to taste.
7. Simmer: Bring to a gentle simmer. Cover the skillet and cook for 30-35 minutes, or until the chicken is cooked through and the potatoes are tender.
8. Adjust Seasoning: Taste and adjust the seasoning as necessary, adding more salt, pepper, or red pepper flakes as desired.
9. Serve: Once cooked, remove from heat and let it rest for a few minutes before serving. Garnish with chopped fresh parsley.

These steps will guide you to create an amazing Chicken Scarpariello that will impress your family and friends.
