Preparing French Onion Chicken Orzo Casserole
Making a French Onion Chicken Orzo Casserole is not just about following a recipe; it’s about crafting a delightful, comforting meal that feels like a warm hug after a long day. Let’s dive into each step of this delicious journey!
Caramelize the Onions
The foundation of a great casserole starts with 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, along with 1 teaspoon of sugar and ½ teaspoon of salt.
Stir the mixture occasionally for about 20-25 minutes, until the onions become wonderfully golden and caramelized. This process isn’t just about cooking the onions; it’s about coaxing out their natural sweetness. To elevate the flavor even further, toss in 3 minced garlic cloves during the last 1-2 minutes of cooking.

Add Orzo and Chicken
Once your onions are perfectly caramelized, it’s time to add in the star ingredients that make this casserole so special. Stir in 1 ½ cups of orzo pasta and toast it for about 2 minutes. This subtle toasting enhances the pasta’s flavor and texture. Then, introduce 2 cups of cooked shredded chicken—using rotisserie chicken works wonders for saving time! Add in ½ teaspoon of dried thyme and ¼ teaspoon of black pepper, mixing until everything is well combined.
Pour in Broth and Cream
Now comes the magic! Pour in 2 cups of low-sodium chicken broth and 1 cup of heavy cream (or half and half for a lighter touch). Bring this delightful mixture to a gentle simmer. Reduce the heat to low, cover it, and let it cook for about 8-10 minutes, stirring occasionally, until the orzo is tender. This step not only cooks the pasta but also allows all those wonderful flavors to meld beautifully.
Incorporate the Cheeses
What’s a casserole without cheese? Stir in 1 cup of shredded mozzarella cheese and ½ cup of grated Parmesan cheese. As you mix, you’ll witness the transformation from a simple dish into a creamy, cheesy delight. Feel free to get creative here—consider adding a bit of grated Gruyere for an extra depth of flavor!
Bake the Casserole
Preheat your oven to 375°F (190°C), and sprinkle the remaining ½ cup of mozzarella cheese over the top of your casserole. This is where the magic happens. Bake uncovered for 10-15 minutes until the top is bubbly and golden brown. That aromatic smell filling your kitchen? Pure bliss!
Let your French Onion Chicken Orzo Casserole rest for 5-10 minutes before serving. Consider garnishing with fresh thyme or parsley to elevate the presentation.
Now, dive in and enjoy this comforting meal that’s sure to impress everyone around your dining table!
