Gather these ingredients

Let’s round up what you’ll need to make this dish sing!

• Unsalted Butter (2 tablespoons): The foundation of flavor—this helps to caramelize the onions beautifully.
• Olive Oil (1 tablespoon): For that perfect sear and to prevent the butter from burning—think of it as your dish's best friend!
• Yellow Onions (2 large, thinly sliced): These beauties are the hallmark of French onion flavors, bringing sweetness and depth.
• Sugar (1 teaspoon): Just a pinch to enhance the natural sweetness of the onions—it's like a magic wand for caramelization.
• Salt (1/2 teaspoon): Always essential for bringing out the flavors.
• Garlic (3 cloves, minced): Because garlic makes everything better—trust me!
• Orzo Pasta (1 1/2 cups): This tiny pasta is the star as it absorbs all those lovely sauces.
• Cooked Shredded Chicken (2 cups): Use rotisserie for ease and flavor or any leftover chicken you have on hand.
• Dried Thyme (1/2 teaspoon): A sprinkle of herbal goodness—thyme adds a wonderful earthiness to the dish.
• Black Pepper (1/4 teaspoon): A dash of heat to balance out the creaminess.
• Low-Sodium Chicken Broth (2 cups): The broth provides the perfect liquid base for the orzo to soak in.
• Heavy Cream (1 cup): For richness and that beautifully creamy texture! Half and half works if you’d like a lighter option.
• Mozzarella Cheese (1 1/2 cups shredded): Melts like a dream, creating gooey, cheesy perfection.
• Parmesan Cheese (1/2 cup grated): Adds a nutty, salty bite that complements the mozzarella perfectly.
• Optional: Worcestershire Sauce (1/2 teaspoon) or Balsamic Glaze: These secret agents can deepen the flavors and add a hint of sophistication.

How this recipe comes together

Let’s get down to business, shall we?

1. Caramelize the Onions: In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Toss in those lovely sliced onions, sugar, and a half teaspoon of salt. Cook for about 20-25 minutes, stirring occasionally, until they are deeply golden and caramelized. Remember to stir in the minced garlic during the last minute or two—it’s a subtle touch that makes all the difference.

2. Add Orzo and Chicken: Toss in the orzo and toast it for about 2 minutes—this step really enhances the flavor. Incorporate the shredded chicken, thyme, black pepper, and Worcestershire sauce if you’re using it. Mix it all together until combined.

3. Pour in Liquids: Now, add the chicken broth and cream. Bring it all to a gentle simmer. Lower the heat, cover, and let it cook for about 8-10 minutes, stirring occasionally until the orzo is tender. This is where the magic starts happening!

4. Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese until it melts into a creamy blend. Can you smell that?

5. Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining mozzarella on top and bake uncovered for 10-15 minutes until it’s bubbly and golden.

6. Serve: Once it’s out of the oven, let it rest for about 5-10 minutes before digging in. A quick pat of fresh thyme or parsley for garnish can elevate the dish even more.

How to plate and pair

This casserole can stand proudly on its own, but if you’re in the mood to elevate your dining experience, consider serving it alongside a crisp green salad with a zesty vinaigrette. A simple side of steamed green beans or asparagus can also complement the richness beautifully.

If you’re planning a cozy dinner, pair it with a light white wine, like a Sauvignon Blanc or a Chardonnay, to cut through the creaminess. Trust me; your taste buds will dance with delight!

Keeping leftovers fresh

Got extras? Lucky you! Store any leftovers in an airtight container in the fridge, where it’ll stay fresh for up to 3-4 days. When it comes to reheating, just pop it back in the oven at a low temperature until warmed through; you can add a splash of cream or broth to keep it from drying out.

If you want to freeze it, this casserole holds up nicely! Just let it cool completely, then portion it into freezer-safe containers. It can be frozen for up to three months. When you’re ready to enjoy, thaw in the refrigerator overnight and reheat in the oven.

Pro chef tips

Here are a few pro-level tips to ensure your dish turns out perfectly every time:

• Use a good quality stock: It really makes a difference. Homemade is always best, but if you’re using store-bought, opt for low-sodium!
• Texture balance: If you like a little crunch, consider topping with panko breadcrumbs mixed with some Parmesan before baking for a delightful crispy top.
• Fresh herbs: If you have fresh thyme or parsley on hand, sprinkle some on top just before serving for a bright, herbal finish.

Creative Twists

• Add veggies: Sauté some mushrooms or spinach to add more nutrition and color.
• Switch up the cheese: Try a sharp cheddar or a creamy gouda for different flavor dimensions.
• Swap proteins: Turkey or shredded pork can also make delicious alternatives to chicken.
