- 2 large yellow onions, thinly sliced
- 1 teaspoon sugar
- 1/2 teaspoon salt
- 3 garlic cloves, minced
- 1 1/2 cups orzo pasta
- 2 cups cooked shredded chicken (rotisserie works well)
- 1/2 teaspoon dried thyme
- 1/4 teaspoon black pepper
- 2 cups low-sodium chicken broth
- 1 cup heavy cream (or half and half for a lighter option)
- 1 1/2 cups shredded mozzarella cheese

Ingredient Notes

How to Make It
Cooking this dish is as enjoyable as eating it! Each step fills your kitchen with incredible aromas, transforming your space into a cozy retreat. Let’s dive into how to create this warm and hearty casserole.
Step 1 – Caramelize the Onions
Start by heating a large oven-safe skillet or Dutch oven over medium heat. Melt the unsalted butter with the olive oil until it shimmers. Then, add the sliced onions, sugar, and salt. Now, the magic happens! Stir occasionally and allow them to cook for about 20–25 minutes. You want those onions to become a beautiful golden color, deeply caramelized, and fragrant.
In the last couple of minutes of cooking, stir in the minced garlic. Ah, the aroma of garlic melding with sweet onions is heavenly! It’ll drive everyone in the house wild with anticipation of what’s to come.
Step 2 – Add Orzo and Chicken
Next, sprinkle the orzo into the skillet, giving it a quick stir to coat it in all those glorious onion flavors — you’ll want to let it lightly toast for about 2 minutes. Then, add in the cooked, shredded chicken along with dried thyme and black pepper. If you’re feeling adventurous, splash in the Worcestershire sauce for that extra depth of flavor. Stir everything together until it’s well combined and smells delightful.
Step 3 – Pour in Liquids and Bake
Now, it’s time for the broth and cream. Pour them into the skillet, stirring to incorporate everything. Bring it all to a gentle simmer, then reduce the heat to low, cover, and let it cook for about 8–10 minutes. Stir occasionally until the orzo is tender and soaking up all that flavor.
Once everything is cooked to perfection, remove the lid and stir in 1 cup of shredded mozzarella and the grated Parmesan cheese. Watch in awe as the cheese melts, creating a creamy, dreamy consistency that wraps around all the ingredients.
Preheat your oven to 375°F (190°C) and sprinkle the remaining mozzarella over the top of your casserole. Pop it into the oven uncovered for about 10–15 minutes until bubbly and golden on top.
Tips for Success
- Be patient while caramelizing the onions; it enhances their natural sweetness and complexity.
- Stir frequently during cooking to prevent sticking and even cooking.
- Don’t skip resting the casserole before serving. It allows the sauce to thicken and makes for easier serving.

Recipe Variations
Feeling creative? Here are a few variations you might consider to shake things up:
- Mushroom & Spinach Addition: Sauté fresh mushrooms and spinach along with the onions for an earthy twist and added nutrition.
- Herbed Variation: Swap out the thyme for rosemary or oregano for a different flavor profile.
- Italian Style: Add chopped sun-dried tomatoes and Italian seasoning for a Mediterranean flair.
- Veggie-Loaded: Mix in some steamed broccoli or zucchini slices for extra veggies in the dish.
Serving Ideas
This casserole is comforting on its own, but why not enhance your meal experience? Pair it with a light salad tossed in a lemony vinaigrette or a side of crusty bread to soak up all that goodness from the casserole. For a cozy movie night, serve it with a side of buttery popcorn for a fun twist!
Storage and Freezing
If you’re lucky enough to have leftovers (or if you’re meal prepping), you can store the casserole in an airtight container in the fridge for up to 3–4 days. Reheat it gently in the oven or a microwave until warmed through.
For freezing, let the casserole cool completely, then freeze it in a tightly sealed container for up to 3 months. When you’re ready to enjoy it again, thaw overnight in the fridge and reheat in the oven until bubbly.
