If you prefer a different type of pasta, you could use quinoa or rice, though cooking times may vary. For a dairy-free version, opt for coconut milk or a nut-based cream instead of heavy cream.

How to Make French Onion Chicken Orzo Casserole – Step-by-Step Directions
Step 1 – Prepare Ingredients
Start by gathering all your ingredients and preparing them. Thinly slice the onions, mince the garlic, and shred the cooked chicken if you haven’t done so already. Having everything ready will help ensure a smooth cooking process and avoid any last-minute rush.
Step 2 – Cook the Base
In a large oven-safe skillet or Dutch oven, melt 2 tablespoons of unsalted butter along with 1 tablespoon of olive oil over medium heat. Add the sliced onions, 1 teaspoon of sugar, and 1/2 teaspoon of salt. Cook those for about 20 to 25 minutes, stirring occasionally. The goal is to achieve deep golden, caramelized onions that will infuse the dish with rich flavor.
Step 3 – Add Garlic
As the onions get beautifully caramelized, add the minced garlic into the skillet during the last 1-2 minutes of cooking. This step allows the garlic to release its flavor without burning, enhancing the overall taste of the French Onion Chicken Orzo Casserole.
Step 4 – Stir in Orzo and Chicken
Once the onions and garlic are ready, stir in the 1 1/2 cups of orzo pasta and toast it for about 2 minutes. Then, incorporate the 2 cups of shredded chicken along with 1/2 teaspoon of dried thyme and 1/4 teaspoon of black pepper. Mix everything well to ensure that each ingredient is coated in the flavors of sautéed onions and oil.
Step 5 – Pour in Liquids
Next, pour in the 2 cups of low-sodium chicken broth and 1 cup of heavy cream. Bring this mixture to a gentle simmer. Reduce the heat to low, cover, and let it cook for about 8 to 10 minutes, stirring occasionally. The orzo will absorb the flavors and liquid, cooking until it becomes tender.
Step 6 – Add Cheese
Once the orzo has reached the desired tenderness, it’s time to add the cheese. Stir in 1 cup of shredded mozzarella cheese and the 1/2 cup of grated Parmesan cheese. Keep mixing until the cheese is melted and creates a creamy texture, enriching the casserole.
Step 7 – Preheat Oven
To finish the dish, preheat your oven to 375°F (190°C). This step ensures your casserole will get that golden, bubbly finish in the oven just before serving.
Step 8 – Bake the Casserole
Sprinkle the remaining 1/2 cup of mozzarella cheese over the top of the casserole. Bake uncovered for 10 to 15 minutes until the top is bubbly and golden, creating an inviting appearance that will make anyone eager to dig in.
Step 9 – Rest the Dish
Once your French Onion Chicken Orzo Casserole is finished baking, allow it to rest for about 5 to 10 minutes. This little resting period makes serving easier and allows the flavors to meld together beautifully.
Step 10 – Garnish and Serve
Before serving, consider garnishing the casserole with fresh thyme or chopped parsley for a pop of color. This not only enhances the visual appeal but also adds a herbaceous aroma that’s delightful.
