Ingredients
- 170g (1 cup) orzo pasta
- 56g (4 tablespoons) unsalted butter
- 4 large onions (e.g., yellow or Vidalia), thinly sliced
- 4 cloves garlic, minced
- 5g (1 teaspoon) granulated sugar
- 5g (1 teaspoon) fine sea salt
- 2.5g (1/2 teaspoon) freshly ground black pepper
- 3g (1 teaspoon) fresh thyme leaves, stripped from the stem
- 240ml (1 cup) rich vegetable broth
- 240ml (1 cup) heavy cream (35% fat content recommended)
- 120g (1 cup) grated Gruyère cheese, divided
- 60g (1/2 cup) grated Parmesan cheese, divided
- 15g (1/4 cup) chopped fresh parsley, for garnish
Instructions
- Preheat your oven to 190°C (375°F). Prepare a 23×33 cm (9×13 inch) baking dish by lightly greasing it with butter or cooking spray.
- Cook the orzo pasta according to its package instructions until it is perfectly al dente. This typically means cooking for 8-10 minutes. Drain the pasta thoroughly and set it aside to prevent it from clumping.
- In a large, heavy-bottomed skillet or Dutch oven, melt the 56g (4 tablespoons) of unsalted butter over medium heat. Ensure the butter is fully melted before adding the onions.
- Add the thinly sliced onions to the skillet. Sauté them for approximately 20-25 minutes, stirring occasionally, until they become beautifully soft, deeply golden brown, and caramelized. Patience is key here, as this step develops the rich, sweet flavor foundation of the dish.
- Incorporate the 4 cloves of minced garlic, 5g (1 teaspoon) of granulated sugar, 5g (1 teaspoon) of fine sea salt, 2.5g (1/2 teaspoon) of freshly ground black pepper, and 3g (1 teaspoon) of fresh thyme leaves into the caramelized onions. Continue to cook for an additional 2 minutes, stirring frequently, until the garlic is fragrant and the spices are well-distributed.
- Carefully pour in the 240ml (1 cup) of vegetable broth and 240ml (1 cup) of heavy cream. Bring the mixture to a gentle simmer, then reduce the heat slightly and cook for 5-7 minutes, stirring occasionally, until the sauce has slightly thickened to a luxurious consistency.
- In a large mixing bowl, combine the cooked orzo pasta, the rich caramelized onion and cream mixture, half of the 120g (1 cup) grated Gruyère cheese, and half of the 60g (1/2 cup) grated Parmesan cheese. Mix all ingredients thoroughly until the orzo is evenly coated and the cheeses are well-distributed throughout the blend.
- Transfer the entire orzo and onion mixture into the greased 23×33 cm (9×13 inch) baking dish, spreading it evenly.
- Evenly sprinkle the remaining half of the Gruyère cheese and Parmesan cheese over the top of the orzo bake. This will create a magnificent golden, bubbly crust.
- Bake the dish in the preheated oven for 25-30 minutes, or until the cheese topping is gloriously golden brown, bubbly, and the edges are slightly crisped.
- Once removed from the oven, allow the French Onion Orzo Bake to rest for a few minutes (about 5-10 minutes) before serving. This allows the dish to set, making it easier to serve. Garnish generously with the 15g (1/4 cup) of freshly chopped parsley just before serving. Serve warm and enjoy.
Tools You’ll Need
- Large oven-safe skillet or Dutch oven
- Large pot for cooking pasta
- Cutting board and sharp knife
- Cheese grater
- Large mixing bowl
- 23×33 cm (9×13 inch) baking dish
- Spatula or wooden spoon
- Measuring cups and spoons
Essential Success Tips
- Be patient with the onions; true caramelization takes time and is crucial for the dish's depth of flavor. Don't rush this step.
- Cook the orzo truly al dente, as it will continue to absorb liquid and cook further in the oven. Undercooking slightly will prevent it from becoming mushy.
- Use good quality cheeses like a true Gruyère and Parmesan for the best flavor and melt. Freshly grated cheese melts much better than pre-shredded.
- Don't skip the resting period after baking; it helps the bake set, preventing it from falling apart when served.
- Taste the onion mixture before combining with orzo and adjust seasoning as needed, especially salt and pepper, to ensure a well-balanced flavor.
Professional Cooking Secrets
- To achieve exceptionally deep caramelization for the onions, consider adding a splash of balsamic vinegar or dry sherry during the last few minutes of cooking. It enhances richness without overpowering the dish.
- For an even richer sauce, substitute a portion of the vegetable broth with a good quality dry white wine (like Sauvignon Blanc or Pinot Grigio) when deglazing the pan after caramelizing the onions.
- When grating Gruyère, grate it on the larger holes of a box grater for better melt and a more pronounced cheese pull on top.
Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the oven or microwave.
- Freezing: The baked orzo can be frozen after it cools completely. Cover tightly with foil and plastic wrap. Thaw overnight in the refrigerator and reheat in the oven at 180°C (350°F) until heated through and bubbly.
- Variations: For a richer, meatier flavor, you can add 120g (1/2 cup) cooked, crumbled bacon or prosciutto to the orzo mixture before baking. To make it vegetarian, ensure your vegetable broth is truly plant-based.
Frequently Asked Questions
Can I use different types of pasta for this bake?
While orzo is ideal for its small size and ability to blend seamlessly with the creamy sauce, small pasta shapes like ditalini, small shells, or even elbow macaroni could be substituted. Adjust cooking times accordingly.
What kind of onions are best for caramelizing?
Yellow onions or Vidalia onions are excellent choices for caramelizing. They have a natural sweetness that intensifies beautifully when cooked slowly, developing that signature French onion flavor.
Can I make this dish ahead of time?
Yes, you can assemble the entire dish (without baking) up to 24 hours in advance. Cover it tightly and refrigerate. Before baking, let it come closer to room temperature for about 30 minutes, then bake as directed, potentially adding an extra 5-10 minutes to the baking time if still very cold.
