Ingredients
Scale
For the Onion Base
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 3 large yellow onions, thinly sliced
- 3 cloves garlic, minced
- 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)
- 1 teaspoon salt (or to taste)
- ½ teaspoon freshly ground black pepper
- 1 tablespoon balsamic vinegar
For the Orzo Bake
- 1 cup dry orzo pasta
- 2 cups beef broth (low sodium preferred)
- ½ cup heavy cream
- 1 cup shredded Gruyère cheese (or Swiss cheese)
- 1 cup shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
Optional Garnish
- Fresh parsley or chives, chopped
Instructions
- Caramelize the Onions: In a large oven-safe skillet or sauté pan, melt the butter with the olive oil over medium-low heat. Add the thinly sliced onions and cook slowly for 25 to 30 minutes, stirring often, until they become deeply golden and caramelized. This slow cooking develops the rich flavor base essential for the dish.
- Add Garlic and Seasoning: Stir in the minced garlic, fresh thyme, salt, and freshly ground black pepper. Cook for 1 minute to release the garlic aroma, then deglaze the pan by adding balsamic vinegar. Stir well to lift any browned bits from the bottom, enhancing the overall flavor.
- Add Orzo and Liquids: Mix in the dry orzo pasta, then pour in the beef broth and heavy cream. Bring the mixture to a gentle simmer, then reduce heat slightly and cook uncovered for 8 to 10 minutes. Stir occasionally until the orzo is mostly tender and most of the liquid is absorbed, creating a creamy consistency.
- Add Cheese: Stir in half of the shredded Gruyère and mozzarella cheese until melted and creamy. Evenly sprinkle the remaining Gruyère, mozzarella, and all the grated Parmesan cheese on top of the skillet mixture.
- Bake: Preheat the oven to 400°F (200°C). Transfer the skillet to the preheated oven and bake for 10 to 15 minutes. Bake until the cheeses are bubbly and golden on top, creating a delicious crust.
- Garnish & Serve: Let the orzo bake cool for a few minutes to set. Garnish with freshly chopped parsley or chives if desired. Serve warm as a hearty main or side dish.
Notes
- Use a large oven-safe skillet to avoid transferring the mixture into a separate baking dish.
- Cook onions slowly to develop authentic caramelized flavor; rushing this step may result in bitter or underdeveloped taste.
- Low sodium beef broth is recommended to control salt levels in the dish.
- Gruyère cheese provides a nutty flavor, but Swiss cheese is a good substitute if unavailable.
- For a vegetarian version, substitute beef broth with vegetable broth.
- Optionally garnish with fresh herbs like parsley or chives for added color and freshness.
