How to Portion, Cook, and Freeze

For two people: Cut the recipe in half and bake in an 8×8-inch pan. You’ll likely have a bit for the next day.
Freezing advice: Because this recipe contains fresh spinach and raw tomatoes, freezing the assembled, unbaked casserole is not recommended. Leftovers that have already been baked freeze and reheat well.
Reheating: Thaw frozen portions in the refrigerator and reheat gently in the microwave or oven until warmed through.

Simple Instructions for Making Tuscan Orzo Chicken Casserole

Follow these steps for a straightforward assembly. Oven temperature and timing are included below.

1. Toss diced chicken with olive oil and spices and spread in the bottom of the pan.
2. Layer garlic, cherry tomatoes, and sun-dried tomatoes on top.
3. Add fresh spinach and dry orzo over the tomato layer.
4. Pour chicken stock and cream over everything and stir to combine.
5. Bake until the orzo is tender and the chicken is cooked through.
6. Sprinkle Parmesan cheese on top and return to the oven until it melts and the top is lightly golden.

Step-by-step Directions

Preheat the oven to 400°F (200°C). Spray a 9×13-inch baking pan with nonstick spray.
Place the diced chicken in the pan and toss with olive oil, salt, pepper, Italian seasoning, onion powder, paprika, and dried basil until well coated.
Layer minced garlic, cherry tomatoes, and chopped sun-dried tomatoes over the chicken.
Add the fresh spinach and spread the dry orzo evenly over the top.
Pour chicken stock and heavy cream over everything, then gently stir so the liquid reaches the orzo and the ingredients are evenly distributed.
Bake at 400°F for 35–40 minutes, or until the orzo is tender and the chicken is cooked through. Sprinkle Parmesan on top and bake 4–6 more minutes, until the cheese melts.
Let the casserole rest for a few minutes before serving to allow the sauce to thicken and the flavors to meld.

Helpful Tips

Do not rinse the dry orzo before adding it to the casserole — it needs to absorb the cooking liquid.
Dice and portion chicken ahead and freeze for quick assembly later.
If the casserole seems dry after baking, stir in a splash more cream before adding the Parmesan and finish baking.
For a lighter option, replace the heavy cream with plain Greek yogurt (about 1/4 cup) mixed into the stock.
Add vegetables such as diced bell peppers or mushrooms to increase the veggie content.
Wipe any spills from the pan edges before serving for a cleaner presentation.
