1. Preheat your oven to 400°F (200°C). Prepare a baking dish by lightly greasing it with olive oil.
2. In a small bowl, mix together the garlic powder, onion powder, paprika, oregano, salt, and pepper.
3. Rub the chicken breasts with olive oil, then sprinkle the seasoning mix evenly over them, ensuring all sides are coated.
4. Place the chicken breasts in the prepared baking dish, and drizzle with lemon juice.
5. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the juices run clear. A meat thermometer should read 165°F (75°C).
6. Remove from the oven and let the chicken rest for 5 minutes before slicing. This helps retain the juices.
7. Garnish with freshly chopped parsley before serving.

This method is foolproof and something I often rely on when I want a stress-free dinner. Just like my abuela, who would let the aroma of her cooking fill the house, I love when the smell of this baked chicken wafts through my home, signaling that something delicious is about to be enjoyed.
