Preparing French Onion Chicken Orzo Casserole
Creating a delightful French Onion Chicken Orzo Casserole is easier than you might think. This creamy, savory dish combines perfectly caramelized onions, tender chicken, and orzo pasta into a one-dish meal that feels like a warm hug. Let’s take it step by step!
Caramelize the Onions
The first step to achieving that rich flavor is to caramelize 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. Add 2 large yellow onions (thinly sliced), 1 teaspoon of sugar, and ½ teaspoon of salt.
Now, this is where patience pays off. Cook the onions for about 20-25 minutes, stirring occasionally. You want them to develop a beautiful golden brown color. During the last minute or two, stir in 3 minced garlic cloves for an aromatic boost. Caramelized onions can elevate any dish, transforming them into something truly special.
Toast the Orzo and Add Chicken
With those sweet caramelized onions ready to go, it’s time to toast the orzo. Add 1 ½ cups of orzo pasta to the skillet and sauté for around 2 minutes. This step adds a nutty flavor that beautifully complements the dish. Next, incorporate 2 cups of cooked shredded chicken—using rotisserie chicken makes this step even easier! Sprinkle in ½ teaspoon of dried thyme and ¼ teaspoon of black pepper. Stir everything together until well combined.
Pour in the Broth and Cream
Once the pasta and chicken are mixed in, it’s time for the comforting liquids. Pour in 2 cups of low-sodium chicken broth along with 1 cup of heavy cream (or half and half for a lighter option). Bring this mixture to a gentle simmer, and then reduce the heat. Cover the skillet, allowing it to cook for about 8–10 minutes. This will ensure the orzo becomes tender, soaking up all those delicious flavors.
Incorporate the Cheeses
Now comes everyone’s favorite part—cheese! Stir in 1 cup of shredded mozzarella cheese and ½ cup of grated Parmesan cheese. Mix until everything is melted and creamy, creating that rich cheesy goodness that’s the hallmark of a great casserole. You can even use a blend of cheeses for a delightful twist.
Bake to Perfection
Preheat your oven to 375°F (190°C). Once everything is mixed and creamy, sprinkle the remaining ½ cup of mozzarella on top. Bake uncovered for 10-15 minutes until it’s bubbly and gets that beautiful golden crust.
Let your French Onion Chicken Orzo Casserole sit for about 5–10 minutes before diving in. Garnish with fresh thyme or parsley if you want to impress your dinner guests. Enjoy this comforting meal that’s perfect for any occasion!
