2large chicken breasts – about 3 cups cooked - diced
1Tbspolive oil
3cupschicken broth
1cupheavy cream
16ozorzo pasta – uncooked
3cupsbaby spinach – about 3 handfuls
2cupscherry or grape tomatoes – halved
1½cupsshredded mozzarella cheese – divided in half
⅔cupfreshly grated parmesan cheese – divided in half
1Tbspfresh lemon juice
½tspdried oregano
Salt and pepper - to taste
Optional to Serve: Crumbled feta or chopped fresh parsley for garnish
Instructions
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.
If using raw chicken, slice chicken breasts in half lengthwise and season with salt and pepper. Heat olive oil in a skillet over medium heat and cook for about 4 minutes per side, or until fully cooked. Let cool slightly, then dice into bite-sized pieces. (If using pre-cooked or rotisserie chicken, skip this step.)
In the prepared casserole dish, combine chicken broth, heavy cream, uncooked orzo, baby spinach, halved tomatoes, ½ of the mozzarella, ½ of the parmesan, lemon juice, oregano, and salt and pepper to taste. Stir until evenly mixed.
Add the diced chicken and stir again so everything is evenly coated and spread into an even layer.
Sprinkle the remaining mozzarella and parmesan evenly over the top.
Bake uncovered for 40–45 minutes, or until the orzo is tender and most of the liquid is absorbed.
Remove from the oven and let rest for 10 minutes before serving. This allows the sauce to thicken slightly. Stir gently before serving.
Garnish with feta cheese or fresh parsley if desired.

Notes
Grease the dish first: A quick swipe of oil helps prevent sticking.
Cover that orzo: Make sure all the orzo is covered with liquid so it cooks evenly.
Rotisserie shortcut: If using cooked chicken, dice and toss it right in — no skillet needed.
Check for doneness: The orzo should be soft but not mushy. Add a splash of broth if it looks dry.
Let it rest: Resting helps the sauce set and turn perfectly creamy.
Use fresh cheese: Freshly grated Parmesan melts smoothly and adds better flavor.
Add a little heat: A pinch of red pepper flakes before baking adds subtle spice.
Don’t overbake: The sauce should look slightly loose — it thickens as it cools.
