Bake covered: Cover with foil and bake for 30 minutes. Carefully uncover, stir in the spinach and parmesan.

Finish baking uncovered: Stir in a splash of cream if you want a creamier dish. Scatter mozzarella balls on top, if using. Bake uncovered for another 5-10 minutes, or until the orzo is tender.

Notes
Chicken: Rotisserie, leftover, or cooked chicken breast all work great. Aim for about 3 heaping cups.
Broth: Use low-sodium broth to better control saltiness. Adjust seasoning to taste.
Creaminess: The dish is creamy from the Boursin alone. A splash of cream at the end makes it extra luscious but is totally optional.
Mozzarella Balls: Optional but highly recommended if you love cheesy bites throughout!
Storage: Store leftovers in the fridge for 3–4 days. Reheat with a splash of broth or cream if needed.
