Make sure you have all your ingredients prepped—slice the onions, shred the chicken, and mince the garlic—so that when it’s time to cook, everything flows smoothly.

Ingredients

2 tablespoons unsalted butter
1 tablespoon olive oil
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 lighter option
1 1/2 cups shredded mozzarella cheese
1/2 cup grated Parmesan cheese
Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze for added depth
Fresh parsley or thyme for garnish

Instructions

Step 1: Caramelize the Onions

To begin, heat a large oven-safe skillet or Dutch oven over medium heat and add the unsalted butter along with the olive oil. Once the butter has melted and the oil is shimmering, add the thinly sliced onions. Sprinkle in the sugar and salt; these will help draw out the moisture from the onions and encourage caramelization. Stir occasionally for about 20-25 minutes until they turn a deep golden brown. In the last couple of minutes, mix in the minced garlic for a fragrant finish.

Step 2: Toast the Orzo

Next, add the orzo pasta to the skillet with the onions and garlic. This quick toast—just about 2 minutes—is essential to enhance its nutty flavor. After toasting, mix in the cooked shredded chicken, dried thyme, and black pepper. If you’re adding the Worcestershire sauce, now is the time to include it. Stir everything thoroughly to combine.

Step 3: Create the Creamy Base

Pour the low-sodium chicken broth and heavy cream into the skillet. It’s important to bring this mixture to a gentle simmer, then lower the heat. Cover the skillet and let it cook for about 8-10 minutes, stirring occasionally. You want the orzo to become tender and the flavors to meld together perfectly.

Step 4: Mix in the Cheese

Once the orzo is tender, fold in 1 cup of the shredded mozzarella and the Parmesan cheese. This will create a luxuriously creamy sauce that beautifully coats the chicken and orzo. Stir until everything is well mixed and the cheese has melted completely.

Step 5: Bake to Perfection

Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella cheese evenly over the top of the casserole. Transfer it to the oven, uncovered, and bake for about 10-15 minutes, or until the cheese is bubbly and golden brown. Once baked, allow the dish to rest for 5-10 minutes before serving; this step helps the flavors settle.

Variations

Protein: Substitute cooked shredded turkey or even roasted vegetables for a vegetarian-friendly option.
Vegetables: Add spinach, mushrooms, or frozen peas for extra nutrients and flavor.
Spices: Experiment with fresh herbs like rosemary or add a kick of heat with red pepper flakes.

Cooking Notes

For added flavor, deglaze the onions with a splash of white wine or balsamic vinegar before adding the orzo.
Using rotisserie chicken saves time and adds incredible flavor; feel free to use leftover chicken as well.
For a lighter dish, use half-and-half instead of heavy cream without sacrificing taste.
If you’re avoiding gluten, swap the orzo for gluten-free pasta or small rice pasta.
Leftover casserole reheats beautifully; add a splash of broth or cream while reheating for optimal creaminess.

Serving Suggestions

Pair this casserole with a simple green salad dressed with vinaigrette.
Serve with crusty bread to soak up the creamy sauce.

Tips

Ensure your onions are sliced evenly for uniform cooking; this prevents burning.
Keep an eye on the orzo during the simmer, as overcooking can lead to mushiness.
If you enjoy a crispy topping, consider broiling the casserole for a minute or two at the end to achieve a golden crust.
Fresh herbs not only add flavor but also appeal visually; garnish generously before serving.
