- 1/2 teaspoon salt
- 3 garlic cloves (minced)
- 1 1/2 cups orzo pasta
- 2 cups cooked shredded chicken (rotisserie works well)

Substitutions & key variations
You can easily modify this recipe based on your preferences or what you have on hand. For a lighter version, use half-and-half instead of heavy cream. If you’re looking for a vegetarian option, swap the shredded chicken for cooked lentils or beans. You can also use different types of cheese, like cheddar or gouda, for a different flavor profile.
Step-by-step
Step 1: 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. Stir in the minced garlic during the last 1–2 minutes.
Step 2: Add Orzo and Chicken
Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Add the shredded chicken, thyme, pepper, and Worcestershire sauce if using. Mix well.
Step 3: Pour in Liquids
Add the chicken broth and cream. Bring to a gentle simmer. Reduce the heat to low, cover, and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender.
Step 4: Add Cheese
Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.
Step 5: Bake the Casserole
Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top. Bake uncovered for 10–15 minutes, until bubbly and golden on top.
Step 6: Serve
Let it rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.
Success tips
- Temperature: Keep the heat on medium for the onion caramelization to ensure they don’t burn.
- Texture: For a creamier texture, make sure to stir the cheese in until fully melted before baking.
- Common Mistakes: Don’t rush the caramelization process; well-cooked onions add a lot of flavor!
How to serve
Serve French Onion Chicken Orzo Casserole hot, directly from the oven. It pairs well with a side salad or crusty bread to soak up the creamy sauce. Feel free to sprinkle some fresh herbs on top for extra flavor and garnish.
