Step-by-Step Preparation of French Onion Chicken Orzo Casserole
Preparing a delicious French Onion Chicken Orzo Casserole is as satisfying as it is straightforward. Just follow these steps, and you'll be enjoying a creamy, comforting dish in no time!
Caramelize the Onions
Start off by creating that rich, sweet flavor we all love about caramelized 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 that have been thinly sliced, along with 1 teaspoon of sugar and ½ teaspoon of salt. This combination of sugar and salt will help the onions release their natural sugars and cook down beautifully. Stir them occasionally, about 20–25 minutes, until they transform into a deeply golden, caramel color. Add in 3 minced garlic cloves during the last couple of minutes to infuse that wonderful aroma.
Add Orzo and Chicken
Once your onions are perfect, it’s time to throw in some heartiness. Stir in 1 ½ cups of orzo pasta and allow it to toast lightly in the mixture for about 2 minutes. This quick step enhances the flavor of the orzo. Next, add 2 cups of cooked shredded chicken (rotisserie chicken works like a charm), along with ½ teaspoon of dried thyme, ¼ teaspoon of black pepper, and if you’re feeling adventurous, ½ teaspoon of Worcestershire sauce. Mix everything well, and let those flavors meld together!
Pour in the Liquids
Now, bring your dish to life by pouring in the liquids. Add 2 cups of low-sodium chicken broth and 1 cup of heavy cream (or half and half for a lighter twist). Gently bring it to a simmer. Reduce the heat to low, cover, and let it cook for about 8–10 minutes, stirring occasionally until the orzo is tender.
Incorporate the Cheese
What’s more comforting than a cheesy casserole? You’ll want to stir in 1 cup of shredded mozzarella and ½ cup of grated Parmesan cheese until everything is melted and creamy. The cheese adds that luscious richness that will have everyone coming back for seconds!
Bake the Casserole
Preheat your oven to 375°F (190°C) while you prep for the final step. Sprinkle the remaining ½ cup mozzarella cheese over the top of the casserole and place it in the oven. Bake uncovered for about 10–15 minutes or until it’s bubbling and golden brown.
Serve and Enjoy
Finally, allow your delightful French Onion Chicken Orzo Casserole to rest for 5–10 minutes before serving. This step allows the flavors to settle. For a fresh touch, consider garnishing with some chopped thyme or parsley. Dig in and savor every bite of this cozy, heartwarming dish that feels like a big hug on a plate!
