Creating this incredible dish is simple if you follow these steps:

1. Preheat your oven to 375°F (190°C).
2. Sauté the Chicken: In a large oven-safe skillet, heat olive oil over medium-high heat. Season chicken breasts with salt and pepper, then add to the skillet. Sear for about 5-7 minutes on each side until golden brown. Remove and set aside.
3. Cook the Vegetables: In the same skillet, add diced onion and cook until translucent. Add minced garlic and cook for an additional minute.
4. Add Tomatoes and Spinach: Stir in the cherry tomatoes and chopped spinach, cooking until the spinach wilts.
5. Combine Ingredients: Add the orzo pasta, chicken broth, heavy cream, dried basil, and dried oregano. Mix well to combine.
6. Nestle the Chicken: Return the seared chicken breasts to the skillet, placing them on top of the orzo mixture.
7. Bake: Transfer the skillet to the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through and the orzo is tender.
8. Add Cheese: If desired, sprinkle grated Parmesan cheese on top during the last 5 minutes of baking for an extra layer of flavor.
9. Let it Rest: Once done, remove from the oven and let it rest for a few minutes before serving.
