Ingredients
Scale
Orzo Pasta
- 1 cup orzo pasta
Onions & Aromatics
- 4 large yellow onions, thinly sliced
- 3 cloves garlic, minced
- 1 tsp fresh thyme leaves
- 1 tbsp butter
- 1 tbsp olive oil
- Pinch of salt
- 1/4 cup dry white wine or broth (optional for deglazing)
Broth & Cream
- 4 cups beef or vegetable broth
- 1/2 cup heavy cream
Cheeses
- 3/4 cup shredded Gruyère or Swiss cheese
- 1/4 cup grated Parmesan cheese
Instructions
- Caramelize the onions: In a large oven-safe skillet, heat butter and olive oil over medium-low heat. Add the sliced onions with a pinch of salt and cook slowly, stirring occasionally until deeply golden and soft, which takes about 30 to 40 minutes. This slow cooking develops the deep sweet flavor essential for the dish.
- Add garlic and thyme: Stir in minced garlic and fresh thyme during the last few minutes of cooking the onions, letting them cook for about one minute until fragrant. This adds aromatic depth to the base.
- Deglaze the pan: Pour in a splash of white wine or broth to deglaze the pan, scraping the bottom with a wooden spoon to lift and incorporate the browned bits for extra flavor.
- Add orzo and broth: Stir the uncooked orzo into the onion mixture, then pour in the broth. Bring to a simmer and cook for 8 to 10 minutes, stirring occasionally, until the orzo is nearly tender but still al dente.
- Add cream and cheese: Lower the heat and stir in the heavy cream and most of the Gruyère or Swiss cheese. Mix well until the cheese melts and the mixture is creamy.
- Bake until bubbly: Sprinkle the remaining cheese on top and transfer the skillet to a preheated oven. Bake at 350°F (175°C) for 15 to 20 minutes until the top is golden and bubbling.
- Broil for a golden top (optional): For an extra golden, cheesy crust, broil for 2 to 3 minutes, watching carefully to prevent burning.
- Let rest and serve: Remove from the oven and let the bake rest for 5 to 10 minutes to allow the sauce to thicken slightly. Garnish with fresh thyme or parsley before serving.
Notes
- Slowly caramelizing the onions is key to unlocking the dish’s rich flavor; don’t rush this step.
- You can substitute vegetable broth for beef broth to make the dish vegetarian.
- The dish can be prepared ahead of time and baked just before serving.
- Leftovers store well in the refrigerator for up to 3 days and reheat nicely.
- Use a heatproof skillet to go from stovetop to oven easily.
