Ingredients
- 2 cups orzo pasta, uncooked
- 1 pound boneless, skinless chicken breasts, diced
- 1 tablespoon olive oil
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 cup broccoli florets, cut into bite‑size pieces
- 1 cup cherry tomatoes, halved
- 1 teaspoon Italian seasoning
- Salt, to taste
- Freshly ground black pepper, to taste
- 2 cups chicken broth (low‑sodium preferred)
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- Fresh parsley, chopped, for garnish
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13‑inch baking dish and set aside.
- Bring a large pot of salted water to a boil. Add the orzo and cook according to package directions until al dente. Drain well and set aside.
- Meanwhile, heat the olive oil in a large skillet over medium heat. Add the diced chicken, season with salt, pepper, and Italian seasoning, and cook for 5–7 minutes, stirring occasionally, until browned and cooked through.
- Add the chopped onion and minced garlic to the skillet. Sauté for 2–3 minutes, or until the onion is softened and translucent.
- Stir in the broccoli florets and cherry tomatoes. Cook for an additional 3–4 minutes, just until the broccoli is crisp‑tender and the tomatoes begin to soften.
- In a large mixing bowl, combine the cooked orzo, chicken and vegetable mixture, and chicken broth. Taste and adjust seasoning with more salt and pepper if needed, then mix until everything is evenly coated.
- Transfer the mixture to the prepared 9×13‑inch baking dish, spreading it into an even layer.
- Sprinkle the shredded mozzarella evenly over the top, followed by the grated Parmesan.
- Bake for 25–30 minutes, or until the casserole is hot and the cheese is melted, bubbly, and lightly golden brown on top.
- Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with chopped fresh parsley and enjoy warm.
Variation
- Swap the veggies: Try spinach, peas, bell peppers, or mushrooms in place of or in addition to the broccoli and tomatoes.
- Make it extra creamy: Stir in 1/2 cup heavy cream or 4 oz softened cream cheese with the orzo and broth for a richer, creamier bake.
- Turn it into a cheesy buffalo orzo: Add 1/4–1/3 cup buffalo sauce to the mixture and use a blend of mozzarella and cheddar on top.
Cooking Notes
- Cook the orzo just to al dente; it will continue to soften as it bakes in the oven.
- Dice the chicken into small, even pieces so it cooks quickly and stays tender.
- If the top browns too quickly before the casserole is heated through, loosely tent the dish with foil for the last 5–10 minutes of baking.
Serving Suggestions
- Serve with a simple green salad dressed with lemon and olive oil to balance the richness of the casserole.
- Pair with garlic bread or warm crusty baguette to soak up any cheesy, brothy goodness.
- Add a side of roasted or steamed vegetables (like green beans or asparagus) for an extra boost of color and nutrition.
Tips
- Cut some prep time by using leftover cooked chicken or a shredded rotisserie chicken; simply warm it with the onions and garlic before adding the veggies.
- Grate the Parmesan finely so it melts smoothly into the top layer of cheese.
- This casserole reheats well store leftovers in an airtight container in the fridge for up to 3 days and reheat, covered, at 325°F (165°C) until warmed through.

Frequently Asked Questions
- Can I make this casserole ahead of time?
Yes. Assemble the casserole up to the point of adding the cheese, cover tightly, and refrigerate for up to 24 hours. When ready to bake, top with cheese and bake, adding 5–10 extra minutes if baking from cold. - Can I freeze Cheesy Chicken Orzo Casserole?
Yes. Cool completely, then wrap well and freeze for up to 2 months. Thaw overnight in the fridge and reheat, covered, at 325°F (165°C) until hot and bubbly. - Can I use a different pasta instead of orzo?
Short shapes like small shells, ditalini, or elbow macaroni can work, but be sure to cook them to al dente and keep the total pasta amount roughly the same. - How do I keep the casserole from drying out?
Don’t overbake, use al dente pasta, and make sure there’s enough broth in the mixture before baking. You can stir in a splash of broth or cream if it looks too dry.

Notes

- Let the casserole rest for a few minutes after baking so it sets slightly and scoops cleanly.
