Preheat your oven to 375°F.
In a medium baking dish, combine the uncooked orzo, chicken stock, and heavy cream. Stir to mix.
Add the chopped cooked chicken, shredded mozzarella cheese, crumbled feta cheese, chopped spinach, and chopped red bell pepper. Season with chicken bouillon powder, salt and pepper to your taste. Stir everything together until well mixed.
Drizzle a little lemon-infused olive oil over the top. If you don’t have lemon-infused oil, use regular olive oil and add a small squeeze of fresh lemon juice for brightness.
Place the baking dish in the oven and bake, uncovered, for 40 minutes.
Once the orzo is tender and the top is bubbling, turn on the broiler and let it cook for about 2 minutes to get the top golden brown. Keep an eye on it to avoid burning.
Remove the dish from the oven and let it sit for 10 minutes. This helps everything set and makes it easier to serve.
Give the mixture a quick stir before serving to distribute the creamy sauce and melted cheese.
