Preparing French Onion Chicken Orzo Casserole
The French Onion Chicken Orzo Casserole is a comforting dish that's perfect for any gathering or a cozy night in. Whether you're entertaining friends or just enjoying a quiet evening at home, this recipe will warm your heart and satisfy your taste buds. Let's dive into the steps to prepare this delightful casserole!
Caramelize the Onions
Start with one of the most essential steps: caramelizing the onions. In a large oven-safe skillet or Dutch oven, melt 2 tablespoons of unsalted butter and 1 tablespoon of olive oil over medium heat. Once the butter is bubbling, add in 2 large yellow onions, thinly sliced, along with 1 teaspoon of sugar and ½ teaspoon of salt. This combination helps bring out the natural sweetness of the onions. Cook them for about 20–25 minutes, stirring occasionally. You’re aiming for them to become deeply golden and not just browned. Towards the end, when they’re almost perfect, stir in 3 minced garlic cloves for that extra burst of flavor.
Add the Orzo and Chicken
Now it’s time to bring in the orzo and chicken! After your onions are beautifully caramelized, stir in 1 ½ cups of orzo pasta. Allow this to cook for about 2 minutes to lightly toast it. This step elevates the dish's flavor profile. Next, add in 2 cups of cooked, shredded chicken (rotisserie chicken works splendidly), ½ teaspoon dried thyme, and ¼ teaspoon black pepper. If you want to enhance the flavor even more, feel free to include ½ teaspoon of Worcestershire sauce or a drizzle of balsamic glaze.
Pour in the Liquids
With your orzo and chicken mixed in, it’s time to make things creamy. Pour in 2 cups of low-sodium chicken broth and 1 cup of heavy cream (or half and half if you’re aiming to lighten it up a bit). Stir everything well and bring the mixture to a gentle simmer. Once it’s bubbling slightly, reduce the heat to low, cover, and let it cook for 8–10 minutes. This will soften the orzo beautifully, so keep an eye on it and stir occasionally to ensure nothing sticks to the bottom.
Add the Cheese
Who doesn’t love cheese? After the orzo has cooked to perfection, stir in 1 cup of shredded mozzarella and ½ cup of grated Parmesan cheese. Mix until everything is wonderfully melty and creamy. The comforting aroma will be irresistible!
Bake the Casserole
Preheat your oven to 375°F (190°C). It’s almost time to enjoy your French Onion Chicken Orzo Casserole! Sprinkle the remaining ½ cup of mozzarella over the top of your casserole, then bake uncovered for 10–15 minutes or until the top is bubbly and golden. Allow it to rest for 5–10 minutes after pulling it from the oven to help the flavors meld perfectly.
Serve it up with a sprinkle of fresh thyme or parsley for a pop of color. You're about to become the star of mealtime! If you're interested in more creamy casserole recipes, check out this guide on casserole cooking tips. Enjoy your culinary creation!
