- 1 ½ cups orzo pasta
- 2 tablespoons olive oil or butter
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 2 cups chicken broth
- 1 cup milk or heavy cream
- 1 cup shredded mozzarella or cheddar cheese

How to Make Chicken Orzo Casserole
This recipe comes together in under an hour from start to finish. Here’s how to bring it all together step by step.
Step 1: Sauté the Aromatics
Start by heating olive oil or butter in a large skillet or oven-safe pan. Add diced onions and minced garlic, then sauté until fragrant and translucent. If you’re including mushrooms or spinach, toss them in at this stage. The goal is to build layers of flavor right from the start.
Step 2: Toast the Orzo
Add the orzo to the pan and stir for about a minute. Toasting the pasta gives it a nutty depth that adds richness to the final dish. This small step makes a big difference.
Step 3: Add the Liquid and Simmer
Pour in the chicken broth and milk, stirring constantly to prevent sticking. Let the orzo simmer gently until it begins to absorb most of the liquid. It should still be slightly firm since it will continue cooking in the oven.
Step 4: Combine the Chicken and Cheese
Stir in the shredded chicken, mozzarella, Parmesan, Italian seasoning, salt, and pepper. The cheese will melt into the sauce, creating a creamy, velvety base.
If you want an extra burst of freshness, add lemon juice or zest here. It brightens up the creamy sauce beautifully.
Step 5: Bake to Golden Perfection
Transfer the mixture into a greased casserole dish (or leave it in your oven-safe skillet). Sprinkle a bit more cheese on top and bake at 375°F (190°C) for about 20–25 minutes, or until the top turns golden and slightly crisp.
After baking, let the casserole rest for 5 minutes before serving. this allows it to set and makes scooping easier.
Tips for the Perfect Chicken Orzo Casserole
Even though this recipe is simple, a few smart techniques will take it from good to unforgettable.
- Don’t overcook the orzo: Stop cooking when it’s al dente — it will finish softening in the oven.
- Use quality chicken broth: It’s the backbone of flavor. A rich, homemade, or low-sodium broth makes a noticeable difference.
- Add texture: A sprinkle of breadcrumbs or crushed crackers before baking adds a lovely crunch on top.
- Make it ahead: Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours. Bake it fresh when you’re ready to serve.
