Directions to Follow
- Caramelize the Onions: In a large oven-safe skillet or Dutch oven, combine the butter and olive oil over medium heat. Add the sliced onions, sugar, and salt. Sauté for 20–25 minutes, stirring occasionally, until the onions are golden and caramelized. Stir in minced garlic in the last 1-2 minutes of cooking.
- Add Orzo and Chicken: Incorporate the orzo into the skillet and cook for 2 minutes to lightly toast it. Next, add the shredded chicken, dried thyme, black pepper, and Worcestershire sauce if you choose to add it. Mix everything thoroughly.
- Pour in Liquids: Add the chicken broth and cream. Bring the mixture to a gentle simmer, then reduce the heat to low. Cover and let it cook for 8-10 minutes, stirring occasionally, until the orzo is tender.
- Add Cheese: Stir in 1 cup of mozzarella and the grated Parmesan. Mix until everything is melted and creamy.
- Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella on top. Bake uncovered for 10-15 minutes or until it’s bubbly and golden.
- Serve: Allow the casserole to rest for 5-10 minutes before serving. For a fresh touch, garnish with thyme or parsley if desired.
Best Ways to Enjoy It
When it comes to serving this delectable dish, think comfort food! I love to present it right out of the oven in the skillet for that homey feel. Pair it with a simple green salad or some crusty bread to balance the richness. You could also serve it with steamed vegetables for an extra nutritional punch.
Keeping Leftovers Fresh
If you find yourself with leftovers (which is rare because it’s so good), make sure to store them properly. Allow the casserole to cool completely before transferring it to an airtight container. It will keep well in the fridge for up to 3 days. For longer storage, you can freeze it in suitable containers for up to 2 months. Just reheat in the oven or microwave until heated through.
Extra Advice
- Don’t Rush the Onions: Caramelizing onions takes time, but it’s worth every minute. Aim for a deep golden color for optimal flavor.
- Texture Matters: If you’re worried about the orzo becoming mushy, stir it gently after adding the liquids and keep an eye on the cooking time.
- Cheese Choices: Feel free to experiment with different cheese blends—try adding a bit of sharp cheddar or gouda for a different flavor profile.
Flavor Swaps
Want to mix things up? Here are a few ideas:
- Vegetarian Option: Swap out the chicken for mushrooms or a medley of your favorite vegetables.
- Spicy Kick: Add some crushed red pepper flakes or a dash of hot sauce for an unexpected twist.
- Herb Variations: Try substituting thyme with rosemary or basil for a fresh twist.
