Ingredients

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
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: fresh parsley or chives for garnish

Instructions

Step 1: In a large oven-safe skillet or sauté pan, melt the butter with olive oil over medium-low heat. Add the sliced onions and cook slowly for 25–30 minutes, stirring often, until deeply golden and caramelized. Don’t rush—this step adds all the flavor.
Step 2: Stir in the minced garlic, thyme, salt, and pepper. Cook for 1 minute. Deglaze the pan with balsamic vinegar, stirring well to lift any browned bits from the bottom.
Step 3: Stir in the dry orzo pasta, then pour in the beef broth and heavy cream. Bring to a simmer, reduce heat slightly, and cook uncovered for 8–10 minutes, stirring occasionally, until the orzo is mostly tender and the liquid mostly absorbed.
Step 4: Stir in half of the Gruyère and mozzarella cheeses until melted and creamy. Sprinkle the remaining Gruyère, mozzarella, and all the Parmesan cheese evenly on top.
Step 5: Preheat your oven to 400°F (200°C). Transfer the skillet to the oven and bake for 10–15 minutes, or until bubbly and golden on top.
Step 6: Let the bake cool for a few minutes. Garnish with chopped parsley or chives if desired, then serve warm.

Tips & Variations

To add protein, stir in shredded rotisserie chicken or sautéed ground beef before baking.
For a richer, umami twist, add sautéed mushrooms with the onions.
Use gluten-free orzo or substitute with riced cauliflower for a low-carb version.
Stir in fresh spinach or kale just before baking for extra nutrients.
Add a pinch of red pepper flakes for subtle heat.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave with a splash of cream or broth to loosen the sauce. For longer storage, wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and reheat covered in a 350°F oven or microwave.

Ingredients

Scale

Base Ingredients

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

Pasta and Liquids

1 cup dry orzo pasta
2 cups low sodium beef broth
½ cup heavy cream

Cheeses

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 olive oil over medium-low heat. Add the thinly sliced onions and a pinch of salt. Cook slowly, stirring often, for 25–30 minutes until onions are deeply golden and caramelized, developing sweet, rich flavor. This step is critical to the dish’s signature depth.
Add Garlic and Seasoning: Stir in minced garlic, fresh thyme, salt, and black pepper. Cook for about 1 minute until fragrant. Then deglaze the pan by pouring in the balsamic vinegar and scraping the bottom with a wooden spoon to lift any flavorful browned bits.
Add Orzo and Liquids: Add the dry orzo pasta to the skillet and stir to coat. Pour in the beef broth and heavy cream, then bring to a simmer. Reduce the heat slightly and cook uncovered for 8–10 minutes, stirring occasionally, until the orzo is mostly tender and most of the liquid is absorbed, resulting in a creamy base.
Add Cheese: Stir in half of the shredded Gruyère and mozzarella cheeses into the creamy orzo mixture. Mix well until the cheeses are melted and the mixture is smooth and creamy.
Bake: Preheat the oven to 400°F (200°C). Sprinkle the remaining Gruyère, mozzarella, and all the Parmesan cheese evenly on top of the skillet. Transfer the skillet to the oven and bake for 10–15 minutes, or until the cheese topping is bubbling and golden brown.
Garnish & Serve: Remove from the oven and let the bake cool for a few minutes to thicken slightly. Garnish with freshly chopped parsley or chives if desired, then serve warm for a comforting meal.

Notes

Use small pasta shapes similar to orzo if substituting, like couscous or ditalini, keeping in mind cooking times may vary.
This dish can be made ahead by completing all steps up to the bake, then refrigerating. Allow to come to room temperature before baking.
For a vegetarian version, use vegetable broth and ensure cheeses are vegetarian-friendly.
Freeze the cooked bake for up to 2 months; thaw overnight in the refrigerator and reheat in the oven with a splash of broth or cream to restore creaminess.
Store leftovers in an airtight container in the fridge for up to 4 days; reheat gently on stovetop or microwave with added liquid if needed.
For additional flavor or variation, add cooked shredded rotisserie chicken, sautéed mushrooms, or greens such as spinach or kale before baking.
To make the dish spicy, add a pinch of red pepper flakes during garlic and seasoning step.
