Ingredients & Notes
Orzo Pasta: Absorbs flavors beautifully; cook until just tender for a creamy texture.
Yellow Onions: Slowly caramelized to develop natural sweetness and depth.
Butter & Olive Oil: A combination that ensures golden, flavorful onions.
Garlic & Thyme: Adds aromatic richness.
Beef or Vegetable Broth: Infuses the pasta with savory goodness.
Heavy Cream: Creates a luscious, creamy sauce.
Gruyère or Swiss Cheese & Parmesan: Melt into gooey, golden perfection.
Step-by-Step Instructions
- Caramelize the Onions:
In a large oven-safe skillet, melt butter with olive oil over medium-low heat. Add sliced onions and cook slowly, stirring frequently, until deeply golden and soft (30–40 minutes). Patience is key! - Add Garlic and Thyme:
Stir in minced garlic and fresh thyme during the last few minutes of caramelizing. Cook until fragrant, about 1 minute. - Deglaze the Pan:
Add a splash of white wine or broth to lift the flavorful browned bits from the pan. Scrape with a wooden spoon for extra depth. - Cook the Orzo:
Stir in the uncooked orzo and pour in the broth. Simmer 8–10 minutes, stirring occasionally, until the orzo is nearly tender. - Add Cream and Cheese:
Lower the heat, then stir in heavy cream and half the Gruyère and mozzarella until creamy. - Bake Until Golden:
Sprinkle remaining cheeses on top and bake in a preheated oven at 400°F (200°C) for 15–20 minutes, until bubbly and golden. Optional: broil 2–3 minutes for a crisp, golden crust. - Serve:
Let rest 5–10 minutes to thicken. Garnish with fresh parsley or chives and serve warm.
Variations & Add-Ins
- Add protein: Stir in shredded rotisserie chicken or sautéed ground beef.
- Make it mushroomy: Add sautéed mushrooms with the onions for extra umami.
- Go gluten-free: Use gluten-free orzo or riced cauliflower for a low-carb option.
- Add greens: Stir in spinach or kale just before baking.
- Spice it up: Add red pepper flakes for subtle heat.
Storage Tips
- Refrigerator: Store in an airtight container for up to 4 days.
- Freezer: Wrap tightly and freeze up to 2 months. Thaw overnight in the fridge before reheating.
