How to Make French Onion Chicken – 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 sliced onions, sugar, and salt. Cook low and slow for 20–25 minutes, stirring occasionally, until the onions become soft, deeply golden, and sweetly fragrant.

Pro Tip: If the onions start to stick, add a tablespoon of water to deglaze. Add the minced garlic during the last 1–2 minutes and stir well.

Step 2: Add Orzo and Chicken

Stir in the orzo and cook for 2 minutes, letting it toast lightly for a nutty flavor. Add shredded chicken, thyme, black pepper, and Worcestershire (if using). Mix to coat evenly with the caramelized onions.

Step 3: Pour in Liquids

Add chicken broth and cream. Bring to a gentle simmer, reduce heat to low, and cover. Let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender and creamy.

Step 4: Add Cheese

Stir in 1 cup of mozzarella and all the Parmesan cheese. Mix until melted and smooth — the sauce should be thick, glossy, and utterly irresistible.

Step 5: Bake the Casserole

Preheat your oven to 375°F (190°C). Sprinkle the remaining ½ cup of mozzarella on top. Bake uncovered for 10–15 minutes, until the cheese is bubbly and golden.

Step 6: Serve

Remove from the oven and let rest for 5–10 minutes. Garnish with fresh thyme or parsley for a pop of color. Serve hot — every spoonful delivers comfort and flavor.

Pro Tips & Cooking Secrets

1. Patience is key — let those onions caramelize slowly for full depth.
2. Deglaze often with a splash of broth or balsamic to avoid burning.
3. Use rotisserie chicken for quick prep without sacrificing flavor.
4. Add Gruyère for a more authentic French onion flavor.
5. For extra richness, replace half the broth with white wine.
6. Make ahead: Caramelize onions in advance — they freeze beautifully.
7. Cheese matters: Use freshly grated cheese; pre-shredded can clump.
8. Perfect texture: Stir the orzo as it cooks to prevent sticking.
9. Bake uncovered for that signature cheesy crust.
10. Finish with herbs: Fresh thyme, parsley, or chives elevate the flavor.

Variations & Substitutions

• Mushroom Lover’s Edition: Add sautéed cremini mushrooms with the onions.
• Spinach & Chicken Version: Stir in 1 cup of fresh spinach before baking.
• Spicy Twist: Add a pinch of cayenne or red pepper flakes.
• Extra Creamy: Fold in an additional ½ cup of cream before baking.
• Grain-Free: Swap orzo for cauliflower rice (reduce broth).
• Low-Sodium: Use no-salt broth and unsalted butter.

Best Ways to Serve French Onion Chicken

• Serve with crusty garlic bread to scoop up the sauce.
• Pair with a green salad with lemon vinaigrette for balance.
• Add a glass of white wine — Chardonnay or Sauvignon Blanc pairs beautifully.
• For cozy gatherings, serve in individual ramekins for a French bistro touch.
• Or enjoy leftovers as a lunch reheated in the oven — just as delicious the next day.
