Creating Spanish Chicken in Bravas Sauce is straightforward when you follow these easy steps:

1. Prepare the Chicken: Pat the chicken thighs dry with paper towels. Season both sides with salt and pepper.
2. Heat the Oil: In a large skillet, heat olive oil over medium-high heat until shimmering.
3. Brown the Chicken: Add the chicken thighs, skin side down, and cook for 5-7 minutes until golden brown. Flip and brown the other side for an additional 5 minutes. Remove from the skillet and set aside.
4. Sauté Aromatics: In the same skillet, add the chopped onion. Sauté for 3-4 minutes until softened. Stir in the minced garlic and cook for another minute until fragrant.
5. Add Spices: Sprinkle in the smoked paprika, sweet paprika, and cayenne pepper. Stir to combine and cook for 1-2 minutes to release the flavors.
6. Add Tomatoes: Pour in the crushed tomatoes and red wine vinegar. Stir well, scraping the bottom of the skillet to deglaze.
7. Return Chicken: Place the browned chicken thighs back into the skillet, skin side up. Spoon some of the sauce over the chicken.
8. Simmer: Cover the skillet and reduce heat to low. Let it simmer for 20-25 minutes until the chicken is cooked through and tender.
9. Check for Doneness: Ensure the internal temperature of the chicken reaches 165°F (75°C). Adjust seasoning with salt and pepper if necessary.
10. Rest: Remove from heat and let it rest for 5 minutes before serving.
