How to Make It
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. You’ll know they’re done when they turn that lovely, deep amber color and the sweet aroma fills your kitchen! Just a couple of minutes before they’re finished, stir in the minced garlic for a fragrant addition.
Add Orzo and Chicken
Stir in the orzo and cook for 2 minutes to lightly toast the pasta, giving it a bit of texture. Then, add in the shredded chicken, thyme, and pepper, along with Worcestershire sauce if you opted for it. Mix well, letting those flavors mingle—trust me, your kitchen is going to smell divine!
Pour in Liquids
Next, slowly pour in the chicken broth and cream, bringing it to a gentle simmer. Reduce the heat to low, cover, and let cook for 8–10 minutes. Stir occasionally until the orzo is tender but perfectly al dente. Your kitchen will be warm, cozy, and you might not want to leave!
Add Cheese
Once the orzo is ready, stir in 1 cup of mozzarella and the Parmesan cheese. Mix until everything is melted and creamy. This part is magical—the cheese just brings everything together, making it rich and delightful.
Bake the Casserole
Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella over the top of your concoction. Bake uncovered for 10–15 minutes until bubbly and golden. That glorious cheesy crust will be calling your name!
Serve
Let it rest for 5–10 minutes before serving. For a touch of freshness, garnish with some chopped thyme or parsley, and watch your friends and family gather around the table like moths to a flame!
Pro Tips for Success
- Make sure to slice the onions thinly for even caramelization.
- Don’t rush the caramelizing process—good things take time!
- Use cooked, shredded rotisserie chicken to save time and effort.
- Experiment with different cheeses, such as Gruyère or cheddar, to customize the flavor!
Flavor Variations
- Add sautéed mushrooms or spinach for an earthy twist.
- Swap chicken for cooked sausage or shrimp for a different protein.
- Toss in fresh herbs like basil or parsley for a seasonal kick.
Serving Suggestions
Pair this casserole with a fresh side salad or some crusty baguette to soak up the creamy goodness. For drinks, a chilled glass of white wine or homemade iced tea complements the dish beautifully. And don’t forget to plate it up with a sprinkle of fresh herbs on top—it makes it look oh-so-inviting!
Make-Ahead & Storage
You can prep this dish a day in advance by following the cooking instructions but omitting the baking step. Store it covered in the fridge—just sprinkle with cheese and pop it in the oven when you’re ready to eat. It lasts about 3–4 days in the fridge once cooked.
Leftovers
Don’t let any leftovers go to waste! Use them in a lunch wrap with some greens, transform them into a hearty breakfast by adding some fried eggs on top, or simply reheat for a delicious second dinner.
Freezing
Yes, you can freeze this casserole before baking! Just let it cool completely, then wrap it tightly in aluminum foil and store in an airtight container. It’ll keep well for about 2–3 months. When you’re ready to enjoy it, thaw it in the fridge overnight before baking.
Reheating
For best results, reheat your casserole in the oven at 350°F (175°C) until warmed through, about 15–20 minutes. If you’re short on time, the microwave works too—just make sure to cover it so it retains moisture!
FAQs
Can I use whole wheat orzo instead of regular?
Absolutely! Whole wheat orzo will add a nutty flavor and increase the fiber content—go for it!
What if I don’t have cooked chicken?
No worries! You can poach some chicken breasts while you’re caramelizing the onions, or even use cooked turkey for a twist.
Is it possible to make this gluten-free?
Yes, just use gluten-free orzo and ensure your chicken broth is also gluten-free!
Can I skip the baking step?
Yes! If you’re short on time, you can serve it straight from the stove after mixing in the cheese—just know it won’t have that gorgeous bubbly top.
