Chicken Parmesan Orzo Casserole
This Chicken Parmesan Orzo Casserole gives you tender pasta, juicy chicken, rich marinara, and a crisp cheesy topping without boiling pasta first.
It tastes like chicken parmesan and baked pasta had the easiest weeknight dinner together. The orzo cooks right in the sauce and broth, so it soaks up every bit of garlic, tomato, and Italian seasoning.
Why You’ll Love This Recipe
- Big comfort food flavor: Marinara, garlic, mozzarella, parmesan, and golden breadcrumbs make every bite rich and cozy.
- No separate pasta pot: The dry orzo bakes in the casserole dish with the sauce and broth.
- Great for leftover chicken: Use cooked chicken from a roast, meal prep, or a simple store-bought rotisserie chicken.
- Family-friendly texture: The center stays saucy and tender while the top turns crisp, bubbly, and golden.
Fabian’s Budget Tip: Use leftover cooked chicken and a store brand marinara sauce. If you have only a little chicken, add another 1/2 cup orzo (100 g) and another 3/4 cup broth (180 ml) to stretch the casserole while keeping it filling.

Step-by-Step Instructions
1. Heat the Oven
Preheat the oven to 375°F (190°C). Lightly grease a 9 x 13 inch baking dish with olive oil or butter. The thin coating helps the saucy edges lift out cleanly after baking.
2. Mix the Sauce Base
Add the marinara sauce, chicken broth, minced garlic, Italian seasoning, salt, and black pepper to the baking dish. Stir until the broth turns red and the garlic spreads through the sauce. You should smell the garlic and herbs right away.
3. Add the Orzo and Chicken
Stir in the dry orzo and cooked chicken. Spread everything into an even layer, then press the orzo under the liquid. This matters because any pasta sitting dry on top can stay chewy.
4. Bake Covered Until Tender
Cover the dish tightly with foil. Bake for 35 to 40 minutes, until the edges bubble and the orzo tastes tender with a slight bite. When you lift the foil, the casserole should smell like warm tomato sauce, roasted garlic, and chicken parmesan.
5. Add the Cheesy Breadcrumb Topping
Remove the foil carefully. Sprinkle mozzarella over the hot casserole, then add parmesan and breadcrumbs. Return the dish to the oven uncovered for 10 to 15 minutes, until the cheese melts, the crumbs turn golden brown, and the sauce bubbles around the edges.
6. Rest Before Serving
Let the casserole rest for 10 minutes. The bubbling will calm down, the sauce will thicken, and each scoop will hold together better while still staying creamy.
Expert Troubleshooting and FAQs
Do I cook the orzo before baking?
No. Add the orzo dry. It cooks in the marinara and chicken broth, which gives it more flavor than plain boiled pasta.
Can I use raw chicken?
Use cooked chicken for this recipe. Raw chicken may not cook evenly before the orzo finishes, and it can release extra liquid into the sauce.
Why is my orzo still firm?
Your baking dish, oven, or foil seal may have let too much steam escape. Add 1/4 cup warm broth (60 ml), cover the dish again, and bake for 8 to 10 more minutes.
Why is my casserole watery?
Let it rest for 10 to 15 minutes before serving. Orzo keeps absorbing sauce as it sits. If your marinara is very thin, use 1/4 cup less broth next time.
Can I make this ahead?
Yes. Mix the sauce, broth, seasonings, chicken, and orzo in the dish, then cover and chill for up to 8 hours. Add 5 to 10 minutes to the covered baking time since the dish starts cold.
Can I make it gluten-free?
Yes, use gluten free orzo and gluten free breadcrumbs. Check the package directions because some gluten free pasta softens faster than wheat orzo.
