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 (vegetable broth for vegetarian)
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. Patience is key to build flavor here.
Step 2: Stir in the minced garlic, thyme, salt, and pepper. Cook for 1 minute until fragrant. Deglaze the pan with the balsamic vinegar, stirring well to lift any browned bits from the bottom.
Step 3: Add the dry orzo to the skillet and stir to coat. Pour in the beef broth and heavy cream. 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.
Step 4: Stir in half of the shredded Gruyère and mozzarella cheeses until melted and creamy. Then sprinkle the remaining Gruyère, mozzarella, and all the Parmesan cheese evenly over the 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 before garnishing with fresh parsley or chives if desired. Serve warm and enjoy!

Tips & Variations

To add protein, stir in shredded rotisserie chicken or sautéed ground beef before baking.
For a richer flavor, sauté mushrooms with the onions before continuing.
Use gluten-free orzo or substitute with riced cauliflower for a low-carb option.
Add spinach or kale just before baking to boost the nutrition.
For a little heat, sprinkle in red pepper flakes while cooking the onions.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave, adding a splash of cream or broth to loosen the sauce if needed. You can also freeze this bake for up to 2 months; cool completely, wrap tightly, and thaw overnight in the fridge before reheating in the oven at 350°F.

FAQs

Can I use another type of pasta?

Yes, but it’s best to stick with small shapes like couscous or ditalini to maintain the same texture. Adjust cooking times as necessary.

Can I make this ahead?

Absolutely. Prepare everything up to the stovetop step, then cover and refrigerate. When ready to bake, let it come to room temperature for 15–20 minutes before baking.

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 beef broth, low sodium preferred (vegetable broth for vegetarian option)
½ cup heavy cream

Cheeses

1 cup shredded Gruyère cheese or Swiss cheese
1 cup shredded mozzarella cheese
¼ cup grated Parmesan cheese

Optional Garnishes

Fresh parsley or chives for garnish

Instructions

Caramelize the Onions: In a large oven-safe skillet or sauté pan, melt the butter and olive oil over medium-low heat. Add the thinly sliced onions with a pinch of salt and cook slowly for 25 to 30 minutes, stirring often, until the onions are deeply golden and caramelized. This slow caramelization is essential for developing the rich flavor base.
Add Garlic and Seasoning: Stir in the 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, stirring well to scrape up the browned bits stuck to the bottom, enhancing the dish’s depth.
Add Orzo and Liquids: Stir in the dry orzo pasta, then pour in the beef broth and heavy cream. Bring the mixture to a simmer, then reduce the heat slightly. Cook uncovered for 8 to 10 minutes, stirring occasionally, until the orzo is mostly tender and the liquid has mostly absorbed, creating a creamy base.
Add Cheese: Stir in half of the shredded Gruyère and mozzarella cheese, mixing thoroughly until melted and creamy. Then sprinkle the remaining Gruyère, mozzarella, and all of the Parmesan cheese evenly on top of the orzo mixture.
Bake: Preheat your oven to 400°F (200°C). Transfer the oven-safe skillet to the preheated oven and bake for 10 to 15 minutes until the cheese on top is bubbly and golden brown.
Garnish and Serve: 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, cheesy meal.
