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 thinly sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally, until the onions are deeply golden and caramelized. Just wait until that heavenly aroma fills your kitchen! When you’re close to finishing, stir in the minced garlic during the last 1–2 minutes to allow that beautiful garlic flavor to blossom.
Add Orzo and Chicken
Now, stir in the orzo and let it cook for about 2 minutes to let it toast lightly. This step is so key to infusing that nutty flavor! Mix in the shredded chicken, dried thyme, black pepper, and Worcestershire if you’re using it. Stir it all up and get ready for flavorful magic!
Pour in Liquids
Time to add some delicious moisture! Pour in the chicken broth and cream. Bring everything to a gentle simmer, reduce the heat to low, cover, and let it cook for 8–10 minutes. Stir occasionally to make sure those orzo grains dance around and soak up all that flavor until they’re tender and soft.
Add Cheese
Oh, yes! Now, stir in 1 cup of mozzarella and the lovely Parmesan cheese. Mix everything until it’s melted and creamy. Trust me, you’ll want to dive right into this cheesy bliss!
Bake the Casserole
Preheat your oven to 375°F (190°C). Transfer all that goodness into a lovely bubbling mound and sprinkle the remaining 1/2 cup of mozzarella over the top. Bake uncovered for 10–15 minutes, until it’s all bubbly and golden brown on top. Your kitchen will smell divine at this point!
Serve
Let your masterpiece rest for 5–10 minutes before serving. This is crucial—it allows the casserole to set and makes it easier to serve! Garnish with fresh thyme or parsley if you’re feeling fancy—you’ve just cooked up something spectacular!
Pro Tips for Success
- Watch Your Onions: Caramelizing takes patience, don’t rush! Those golden bits bring tons of sweetness.
- Add More Cheese: If you love a gooey casserole, don’t hesitate to add an extra sprinkle of cheese on top!
- Stir Often: Stirring the orzo ensures it doesn’t stick together. A little love goes a long way!
- Experiment with Herbs: Try adding fresh herbs like parsley or dill for a fresh twist.
- Taste as You Go: Adjust seasoning to your liking; cooking is all about personalizing flavors!
Flavor Variations
- Veggie Boost: Toss in some sautéed mushrooms or spinach for an extra nutritional punch!
- Spice it up: Add a pinch of red pepper flakes if you like a little heat.
- Herb Infusion: Fresh herbs like basil or rosemary can bring in vibrant flavors and aroma.
- Cheese Lovers Delight: Swap out mozzarella for gouda or cheddar for a bolder taste!
Serving Suggestions
This casserole is cozy enough to stand on its own but plays nicely with a fresh green salad, some crunchy garlic bread, or roasted veggies. For drinks, pair it with a crisp white wine, or a sparkling lemonade for a cheerful non-alcoholic option. Don’t forget to use lovely bowls when serving—let’s make dinner special!
Make-Ahead & Storage
For busy days, you can prepare this casserole in advance! Assemble everything in your skillet, cover, and refrigerate for up to 24 hours before baking. When ready, simply pop it in the oven! Leftovers can be safely stored in an airtight container in the fridge for about 3-4 days.
Leftovers
Transform any leftovers into a scrumptious lunch! Toss it into a salad for added heartiness, mix with scrambled eggs for a flavorful brunch, or stuff it into bell peppers and bake for a delightful twist.
Freezing
Yes, you can freeze this beauty! Portion it into airtight freezer containers, ensuring you leave some space for expansion. It will keep well for about 2-3 months. When you’re ready to enjoy, thaw overnight in the fridge or use the microwave for a quick thaw.
Reheating
For the best results, reheat in the oven to keep that lovely cheesy topping crispy. If short on time, the microwave works in a pinch—just add a splash of broth or cream to prevent drying out.
FAQs
Can I substitute the orzo pasta?
Absolutely! If you prefer a different pasta, choose a small variety like ditalini, just adjust cooking times as necessary!
Can I use uncooked chicken?
Yes, just ensure to adjust the cooking time accordingly, cooking until the chicken is thoroughly done before mixing in the other ingredients!
What can I use instead of heavy cream?
You can definitely substitute with half-and-half or even a plant-based cream for a lighter version.
Can I make this gluten-free?
Yes! Just swap the orzo for a gluten-free pasta variety, and check that your broth and other ingredients are gluten-free!
