FRENCH ONION CHICKEN ORZO CASSEROLE INGREDIENTS
The magic of this French Onion Chicken Orzo Casserole truly lies in its harmonious blend of simple ingredients that come together to create something incredible. Don’t worry about exact measurements just yet; those are all in the recipe card for you!
Essential Components
- 2 TABLESPOONS UNSALTED BUTTER: These are the stars! It adds richness and a buttery flavor to the dish.
- 1 TABLESPOON OLIVE OIL: Helps with sautéing and brings a fruity note to the casserole.
- 2 LARGE YELLOW ONIONS (THINLY SLICED): Sweet and savory when caramelized, these onions contribute that signature French onion flavor.
- 1 TEASPOON SUGAR: A small touch to help enhance the sweetness of the onions during cooking.
- 1/2 TEASPOON SALT: Essential for seasoning and balancing flavors.
- 3 GARLIC CLOVES (MINCED): These little gems pack a mighty punch and add fragrant depth to the dish.
- 1 1/2 CUPS ORZO PASTA: The wonderful little pasta that gives the casserole its creamy heartiness.
- 2 CUPS COOKED SHREDDED CHICKEN (ROTISSERIE WORKS WELL): A great way to add protein and make the dish even more satisfying.
- 1/2 TEASPOON DRIED THYME: This herb adds a lovely earthy note that complements the other ingredients.
- 1/4 TEASPOON BLACK PEPPER: A hint of spice to elevate the flavor profile.
- 2 CUPS LOW-SODIUM CHICKEN BROTH: The base for our creamy sauce, enriching the orzo and chicken.
- 1 CUP HEAVY CREAM (OR HALF AND HALF FOR LIGHTER OPTION): For that luxurious, creamy texture that ties everything together.
- 1 1/2 CUPS SHREDDED MOZZARELLA CHEESE: This cheese adds a melty, gooey finish that’s hard to resist!
- 1/2 CUP GRATED PARMESAN CHEESE: For a salty, nutty kick that beautifully complements the mozzarella.
- OPTIONAL: 1/2 TEASPOON WORCESTERSHIRE SAUCE OR BALSAMIC GLAZE: For added depth and a hint of sweetness.
SUBSTITUTIONS AND TIPS
Need a swap? Here are a few options to keep your casserole just as delightful:
- Need a different pasta? Try using small shells or ditalini instead of orzo for a different shape.
- No rotisserie chicken? You can easily use cooked turkey or even canned chicken if you’re in a pinch.
- No heavy cream? Use full-fat coconut milk for a dairy-free option, though it won’t be quite as rich.
- Herb variations: Feel free to throw in some fresh herbs like parsley or basil at the end for a pop of color and flavor!
Timing adjustments can be helpful too. If you’re short on time, you can sauté the onions ahead of time and store them in the fridge. When you’re ready to assemble, it’ll save you a little bit of effort!
KITCHEN TOOLS YOU’LL NEED
- Large oven-safe skillet or Dutch oven (5-quart or larger)
- Wooden spoon or spatula for stirring
- Sharp knife for slicing onions
- Measuring cups and spoons
- Cheese grater (if you’re grating your own cheeses)
HOW TO MAKE FRENCH ONION CHICKEN ORZO CASSEROLE
Let’s dive into creating this wonderfully comforting French Onion Chicken Orzo Casserole. I’ve broken down the process into simple steps. Follow along, and you’ll have a delicious meal in no time. We’re aiming for a creamy, cheesy delight that warms the soul!
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 the onions are deeply golden and caramelized. Stir in the minced garlic during the last 1–2 minutes. This step is key for developing those deep, rich flavors!
Add Orzo and Chicken
Once your onions are beautifully caramelized, stir in the orzo and cook for an additional 2 minutes, allowing it to lightly toast. Then, add in the shredded chicken, thyme, black pepper, and Worcestershire sauce if using. Mix everything together well—this will ensure every bite is bursting with flavor!
Pour in Liquids
Now, add the chicken broth and heavy cream. Bring to a gentle simmer. Once simmering, reduce the heat to low, cover, and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender and has absorbed all those delicious flavors.
Add Cheese
Next, stir in 1 cup of mozzarella and the Parmesan cheese. Mix until everything is melted and creamy, creating that rich sauce we love. It’s already looking good, isn’t it?
Bake the Casserole
Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top to create that irresistible melted crust. Bake uncovered for 10–15 minutes until it’s bubbly and golden on top. You’ll want to keep an eye on it; that cheese should be just right!
Serve
Once you pull it out of the oven, let it rest for 5–10 minutes before serving. This will help the casserole set a bit. If you want to dress it up, garnish with some fresh thyme or parsley for that lovely pop of color and flavor!
HOW TO STORE FRENCH ONION CHICKEN ORZO CASSEROLE
Leftovers of this casserole are a blessing! You can let it sit at room temperature for up to two hours but it’s best to refrigerate it promptly. Store in an airtight container; it will last for about 3-4 days in the fridge. If you happen to have more than you can eat, freezing is also an option! It will keep well for about 2-3 months. Just thaw in the fridge overnight before reheating, then pop it in the oven or microwave until heated through.
TIPS FOR SUCCESS
- Use fresh ingredients whenever possible for the best flavor.
- Don’t rush the caramelization of the onions; patience yields beautiful results.
- Stir occasionally while simmering to prevent sticking.
- Add a splash of white wine while cooking the onions for an added depth of flavor!
- If you want extra cheesiness, sprinkle some additional Parmesan on top before baking.
SERVING SUGGESTIONS
- Pair with a crisp green salad for a light side.
- Serve with crusty French bread to soak up that creamy goodness.
- A glass of Chardonnay complements the flavors beautifully.
- Garnish with fresh herbs for a pop of brightness!
- Consider a side of roasted vegetables for a nutritious boost.
That’s it, my friends! Now you have everything you need to create this French Onion Chicken Orzo Casserole. Bring it to your dinner table, and watch everyone smile with each bite! Enjoy!
