What You’ll Need

Gather These Simple 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)

Let’s Make It Together

  1. Caramelize the Onions: 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—it’s where all the flavor develops.

  2. Add Garlic and Seasoning: Stir in the minced garlic, thyme, salt, and pepper. Cook for an additional minute. Deglaze the pan with balsamic vinegar and stir well to lift any delightful browned bits stuck to the bottom.

  3. Add Orzo and Liquids: Gently stir in the dry orzo, followed by pouring in the beef broth and heavy cream. Bring the mixture to a simmer, reduce the heat slightly, and cook uncovered for 8–10 minutes, stirring occasionally, until the orzo is mostly tender and the liquid is mostly absorbed.

  4. Add Cheese: Stir in half of the Gruyère and mozzarella cheese. This is the moment where it all comes together to create creamy perfection. Sprinkle the remaining Gruyère, mozzarella, and all of the Parmesan on top.

  5. Bake: Preheat your oven to 400°F (200°C). Transfer the skillet to the oven and bake for 10–15 minutes or until the top is bubbly and golden brown.

  6. Garnish & Serve: Let cool for a few minutes. Add a sprinkle of chopped parsley or chives for that final touch of freshness, then serve warm and enjoy every creamy bite!

Chef Emma’s Helpful Tips

  • Make-Ahead Magic: Prep this dish in advance by caramelizing the onions the night before. Then, simply add the remaining ingredients when you’re ready to bake.
  • Ingredient Swaps: If you’re in a pinch, you can use chicken broth instead of beef broth, or even vegetable broth for a vegetarian option.
  • Slicing Tricks: To slice your onions thinly without fuss, use a sharp knife and try cutting them in half through the root, placing the cut side down before slicing.
  • Storage Suggestions: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Simply reheat in the oven or microwave until warmed through.
