Let’s get cooking! Here’s how to bring this dish to life:

1. Preheat your oven to 375°F (190°C). This step is crucial for getting that perfect golden finish on the chicken.
2. Season the chicken breasts with salt, pepper, garlic powder, oregano, and paprika. I find that rubbing the spices in with your hands makes all the difference, just like my dad taught me when we marinated meats together.
3. In a large ovenproof skillet, heat olive oil over medium heat. Add the chicken breasts and sear until golden brown, about 4-5 minutes on each side. This sear locks in the juices, making the chicken tender and flavorful.
4. Add the lemon slices to the skillet, tucking them around the chicken. Pour in the chicken broth and add butter, letting it melt into a luscious sauce.
5. Transfer the skillet to the preheated oven and bake for 20-25 minutes, until the chicken is cooked through and the sauce is bubbling. If you’re adding spinach, toss it in for the last 5 minutes of cooking to let it wilt slightly.
6. Remove from the oven and let it rest for a few minutes before serving. This pause allows the flavors to meld beautifully.

Remember, cooking is about watching, tasting, and adjusting. Don’t be afraid to tweak as you go along!
