How to Make French Onion Chicken Orzo Casserole

Ready to create this comforting dish? Let’s dive right into the steps for making French Onion Chicken Orzo Casserole. You’ll be amazed at how simple and rewarding it is!

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)

Directions

Caramelize the Onions

Start by melting the butter and olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add the thinly sliced onions, sugar, and salt. Cook these lovely ingredients for about 20–25 minutes, stirring occasionally. You want to achieve a deep golden caramelization, which brings out the natural sweetness of the onions. In the last 1 to 2 minutes of cooking, stir in the minced garlic to release its aroma without burning it.

Add Orzo and Chicken

Once the onions are beautifully caramelized, stir in the orzo pasta and toast it lightly for about 2 minutes. This step enhances the flavor of the orzo. Next, add the cooked shredded chicken, dried thyme, black pepper, and Worcestershire sauce if you’re using it. Mix this all together thoroughly.

Pour in Liquids

Now, it’s time to pour in the liquids! Add the chicken broth and cream to the skillet. Bring this mixture to a gentle simmer. Once simmering, reduce the heat to low, cover the pot, and let it cook for 8 to 10 minutes. Stir occasionally to ensure the orzo cooks evenly and absorbs all those flavors.

Add Cheese

After the orzo has cooked and is tender, stir in 1 cup of shredded mozzarella cheese along with the grated Parmesan cheese. Mix everything together until the cheeses melt, creating a creamy and cheesy sauce that binds the ingredients together.

Bake the Casserole

Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top of the orzo mixture. Bake uncovered for 10 to 15 minutes, or until the top is bubbly and golden brown. Your kitchen will smell heavenly!

Serve

Once out of the oven, let the casserole rest for 5–10 minutes. This allows it to set a bit, making it easier to serve. For an extra touch, garnish with fresh thyme or parsley if desired. Serve this dish with a simple side salad or some crusty bread to soak up those delicious flavors!

How to Store French Onion Chicken Orzo Casserole

Store any leftovers in an airtight container in the fridge. This casserole keeps well for about 3–4 days. When you’re ready to enjoy it again, simply reheat in the oven or microwave until warmed through. It makes for a perfect lunch the next day!

Tips to Make French Onion Chicken Orzo Casserole
