Ingredients
- 2 tablespoons butter
- 1 tablespoon olive oil
- 3 large yellow onions, thinly sliced
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme (or ½ teaspoon dried thyme)
- 1 cup dry orzo pasta
- 2 ½ cups beef broth or vegetable broth
- ½ cup heavy cream or half-and-half
- 1 cup shredded Gruyère cheese
- 1 cup shredded mozzarella cheese
- Salt, to taste
- Black pepper, to taste
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a medium baking dish and set aside.
- In a large skillet over medium heat, melt the butter with the olive oil. Add the sliced onions and a pinch of salt. Cook slowly, stirring often, for 20–25 minutes until the onions are deeply golden and caramelized.
- Add the minced garlic and thyme to the onions and cook for 1 minute until fragrant.
- Stir in the dry orzo, coating it in the onion mixture. Toast for about 1 minute.
- Pour in the broth and bring to a gentle simmer. Cook for 5 minutes, stirring occasionally.
- Stir in the cream, season with black pepper, and remove from heat.
- Transfer the mixture to the prepared baking dish. Stir in half of the Gruyère and half of the mozzarella.
- Sprinkle the remaining cheese evenly over the top.
- Cover loosely with foil and bake for 20 minutes.
- Remove the foil and bake an additional 10–15 minutes until bubbly and golden on top.
- Let rest for 5 minutes before serving.
The Secret to Perfect Caramelized Onions
Caramelized onions are the heart of this dish. The key is patience. Cooking them slowly allows their natural sugars to develop, creating a rich, sweet-savory base that defines the flavor of the entire casserole. Avoid turning up the heat too high—low and slow is the way to go.
Variations and Add-Ins
This French Onion Orzo Bake is incredibly versatile. Try these variations to suit your taste:

Vegetarian Upgrade: Stir in sautéed mushrooms or spinach for extra depth and nutrition.
Extra Cheesy: Add a sprinkle of Parmesan or provolone on top before baking.
Gluten-Free Option: Substitute gluten-free orzo or small rice-shaped pasta.

It’s rich enough to stand alone but also works as a show-stopping side dish for gatherings.
