The Cooking Process Explained

Creating this French Onion Chicken Orzo Casserole involves a few straightforward steps that yield a deliciously comforting dish. Here’s how it unfolds:

You’ll start by caramelizing onions to maximize their sweetness.
Then, add the orzo pasta and shredded chicken, infusing it with flavorful herbs and spices.
After a quick simmer with chicken broth and cream, you mix in the cheeses to create a luscious sauce.
Finally, a short bake in the oven transforms this skillet creation into a bubbly, golden masterpiece.

Gather These Items

Here’s what you’ll need for this mouthwatering casserole:

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 a 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)

If you’re looking to lighten it up, feel free to swap out heavy cream for a lighter alternative or adjust the cheese amounts according to your preference.

Step-by-Step Instructions

Caramelize the Onions: In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add the sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally until they are golden and caramelized. Stir in the minced garlic during the last 1–2 minutes.
Add Orzo and Chicken: Stir in the orzo, allowing it to lightly toast for about 2 minutes. Add the shredded chicken, thyme, pepper, and Worcestershire if you choose. Mix well.
Pour in Liquids: Add the chicken broth and cream to the skillet. Bring it to a gentle simmer, then reduce the heat to low, cover, and cook for 8–10 minutes, stirring occasionally until the orzo is tender.
Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until the cheeses are melted and creamy.
Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top. Bake uncovered for 10-15 minutes until bubbly and golden on top.
Serve: Let the casserole rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley, if desired.

Best Ways to Enjoy It

Serve this casserole hot from the oven to highlight its gooey cheese and comforting texture. Pair it with a crisp green salad or serve alongside some crusty bread to soak up the creamy sauce. It also tastes amazing with a side of roasted veggies or a light, herby vinaigrette for an extra touch.

How to Store & Freeze

If you find yourself with leftovers (which is unlikely given how good this is!), store them in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave, adding a splash of broth or cream if it seems a bit dry. You can also freeze the casserole before baking. Just cover it well and it will be good for about 2 months. Thaw it in the fridge overnight before baking.

Practical Cooking Tips

Caramelization is Key: Don’t rush the onion caramelization; it truly makes or breaks the flavor profile.
Add Vegetables: Feel free to toss in some spinach or mushrooms for added nutrition and flavor.
Mix and Match Cheeses: Cheddar or Gruyère can be great alternatives to mozzarella if you’re looking for a different twist.

Creative Twists

Herb Variations: Try using fresh herbs like rosemary or oregano for a different aromatic profile.
Vegetarian Version: Swap the chicken for chickpeas or any other protein you prefer, and use vegetable broth instead of chicken broth.
Add Spice: If you enjoy some heat, consider adding red pepper flakes to bring in a kick.
