Step-by-Step Directions
Step 1: Caramelize the Onions
Heat butter and olive oil in a large skillet over medium heat.
Add sliced onions and cook slowly for 20–25 minutes, stirring occasionally, until golden brown and caramelized.
Add garlic, thyme, and Worcestershire sauce.
Cook for another 1–2 minutes.
This step creates the signature French onion flavor.
Step 2: Prepare the Orzo Mixture
Add dry orzo to the skillet.
Stir for 1 minute to lightly toast it.
Pour in chicken broth and heavy cream.

Stir until slightly melted.
The creamy cheese gives this casserole its rich texture.
Step 5: Transfer to Baking Dish
