Ingredients List

2 tablespoons unsalted butter
1 tablespoon olive oil
2 large yellow onions (thinly sliced)
1 teaspoon sugar
1/2 teaspoon salt
3 garlic cloves (minced)
1 1/2 cups orzo pasta
2 cups cooked shredded chicken (rotisserie works well)
1/2 teaspoon dried thyme
1/4 teaspoon black pepper
2 cups low-sodium chicken broth
1 cup heavy cream (or half and half for lighter option)
1 1/2 cups shredded mozzarella cheese
1/2 cup grated Parmesan cheese
Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze (for added depth)

Ingredient Tips

Onions: Choose yellow onions for their natural sweetness; they caramelize beautifully and add a rich flavor.
Shredded Chicken: Rotisserie chicken saves time, but fresh cooked chicken works wonderfully too; just ensure it’s seasoned to your liking.
Orzo Pasta: This small pasta cooks quickly and absorbs flavors well; if you don’t have orzo, you can substitute with small pasta shapes like ditalini or mini shells.
Cheese: For a bolder flavor, experiment with different cheeses; Gruyère or fontina can add a gourmet touch.

Step-by-Step Instructions

Caramelize the Onions: In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add 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.
Add Orzo and Chicken: Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Add shredded chicken, thyme, pepper, and Worcestershire sauce if using. Mix well to combine the flavors.
Pour in Liquids: Add the chicken broth and cream to the skillet. Bring to a gentle simmer, then reduce heat to low, cover, and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender and has absorbed some liquid.
Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese, mixing until melted and creamy.
Bake the Casserole: Preheat the oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top. Bake uncovered for 10–15 minutes, until the casserole is bubbly and golden on top.
Serve: Allow it to rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired for that extra pop of color and flavor.

Pro Secrets for Success

Use Fresh Ingredients: Fresh herbs and quality cheese significantly enhance the flavor of your casserole.
Don’t Rush the Onions: The magic happens when you slow-cook the onions to bring out their natural sweetness; patience is key!
Stir Regularly: While simmering, give the orzo a stir now and then to prevent it from sticking to the bottom of the skillet.
Adjust Creaminess: Feel free to adjust the amount of cream based on your preference for richness; using half-and-half will lighten the dish while still keeping it creamy.

Recipe Variations

Vegetarian Delight: Substitute the chicken with sautéed mushrooms, zucchini, or spinach for a hearty meat-free option that doesn’t skimp on flavor.
Cheesy Broccoli Addition: Mix in some steamed broccoli or your favorite veggies during the baking stage for extra nutrition and color.
Spicy Kick: Add some red pepper flakes or a dash of hot sauce to inject a little heat into the casserole.
Herb Infusion: Incorporate fresh herbs like parsley, dill, or basil into the mix before baking for a fresh flavor boost.

Perfect Pairings

Serve this hearty casserole with a crisp green salad, crusty bread, or garlic knots to balance the richness. Pair it with a chilled glass of white wine or sparkling water for an elevated dining experience. For dessert, try a light fruit sorbet or chocolate mousse to round off your meal on a sweet note.

Make Ahead & Freezer Tips

To save time, prepare the casserole up to the baking stage. Cover tightly with plastic wrap or aluminum foil and refrigerate for up to 24 hours. For freezing, cool completely before transferring to a freezer-safe dish; it will last for up to 3 months. Reheat by thawing overnight in the refrigerator and then baking at 375°F (190°C) until heated through.

Serving Ideas

For an inviting presentation, serve the casserole directly from the skillet, garnished with fresh herbs. Alternatively, scoop individual portions into bowls and sprinkle with extra cheese before serving to impress guests.

Kitchen Wisdom

Cheese Melting Tip: Grate your cheese instead of using pre-shredded varieties for better melting quality and smoother texture.
Onion Caramelization: If your onions are browning too quickly, reduce the heat to avoid burning and allow for that rich caramel flavor to develop.
Flavor Depth: A splash of balsamic glaze or Worcestershire sauce adds depth and balances the dish, enhancing the overall flavor.
Swap Comfort: For a creative twist, replace traditional chicken broth with homemade or vegetable broth for added depth of flavor.

Storage & Reheating Tips

Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave on medium power, stirring occasionally, or on the stovetop with a splash of chicken broth to maintain moisture without drying out the pasta.
