• 2 tablespoons butter, plus 1 tablespoon butter (or nonstick spray)
• 1 tablespoon extra virgin olive oil
• 3 large white onions, thinly sliced
• 6 garlic cloves, peeled and chopped
• 2 tablespoons honey
• Salt and freshly ground black pepper
• 1 cup dry sherry
• 2 cups beef stock
• 8 sprigs fresh thyme leaves
• 1 lb pasta, cooked al dente (elbow macaroni, ziti, or fusilli work well)

Equipment Needed

• Large saucepan
• Medium saucepan
• 3-quart baking dish or casserole dish
• Whisk
• Mixing bowls
• Grater

Instructions

1. Preheat your oven to 350 degrees F (175 degrees C).
2. Prepare the topping: In a small bowl, thoroughly combine the breadcrumbs and Parmesan cheese. Set this mixture aside.
3. Make the Béchamel Sauce: In a medium saucepan, melt 4 tablespoons of butter over low heat. Add the flour and stir constantly to combine, creating a roux. Continue stirring for about 3 minutes to cook out the raw flour taste.
4. Increase the heat to medium and gradually whisk in the milk or half-and-half, adding a little at a time to prevent lumps from forming. Cook, whisking constantly, until the sauce has thickened, about 4 to 5 minutes.
5. Reduce the heat to low. Season the sauce generously with salt and freshly ground black pepper. Add the Gruyère and mozzarella cheeses. Stir until the cheese is completely melted and the sauce is smooth and creamy. Set the béchamel sauce aside.
6. Begin the French Onion “Soup”: In a large saucepan, heat 2 tablespoons of butter and the olive oil over medium-high heat. Add the thinly sliced onions, cover the pan, and cook for 10 to 15 minutes, stirring frequently to prevent burning.
7. Remove the cover from the pan. Add the garlic and honey. Continue to cook uncovered, stirring frequently, until the onions are deeply caramelized and a rich, golden-brown color, about 10 to 15 minutes longer. Season with salt and a generous amount of pepper. The caramelization is key for the deep, complex flavor.
8. Deglaze the pan: Remove the pot from the heat and carefully add the dry sherry. Be cautious, as it may splatter. Return the pot to the heat and stir to remove any browned bits from the bottom of the pan. Cook over low heat until the sherry is reduced by half, concentrating its flavor.
9. Add stock and thyme: Pour in the beef stock and add the fresh thyme sprigs. Cook until almost all the liquid has evaporated, leaving a concentrated, flavorful onion mixture. Remove the pot from the heat.
10. Prepare the baking dish: Grease a 3-quart baking dish or casserole dish with the remaining 1 tablespoon of butter, or spray it with nonstick cooking spray. This prevents the macaroni and cheese from sticking.
11. Combine everything: In a large bowl, combine the cooked pasta with the French onion “soup” mixture and the béchamel sauce. Stir well to ensure the pasta is evenly coated with the sauce and onions.
12. Transfer the pasta mixture to the prepared baking dish. Sprinkle the breadcrumb/Parmesan topping evenly over the top.
13. Bake: Bake in the preheated oven until the top is golden brown and the cheese is bubbly, about 35 to 40 minutes.
14. Cool and serve: Remove the baking dish from the oven and let it cool slightly before serving. This allows the macaroni and cheese to set up a bit, making it easier to serve.

Expert Tips & Tricks

• Caramelization is King: Don’t rush the caramelization process. It’s the foundation of the soup’s flavor. Low and slow is the key.
• Sherry Substitute: If you don’t have dry sherry on hand, you can substitute dry white wine or even a splash of balsamic vinegar for a tangy depth.
• Cheese Variations: Feel free to experiment with different cheeses in the béchamel. Fontina, Jarlsberg, or even a smoked Gouda can add unique flavor profiles.
• Make Ahead: You can assemble the macaroni and cheese ahead of time and store it in the refrigerator, unbaked, for up to 24 hours. Add a few minutes to the baking time if baking from cold.
• Broiler Boost: For an extra-crispy topping, broil the macaroni and cheese for the last minute or two of baking, keeping a close eye on it to prevent burning.

Serving & Storage Suggestions

Serve this French Onion Soup Macaroni and Cheese warm, straight from the oven, as a comforting main course. It pairs well with a simple green salad or roasted vegetables. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions or bake in a preheated oven at 350°F (175°C) until heated through. For best results, add a splash of milk or cream when reheating to restore moisture. Freezing is not recommended as the sauce may separate upon thawing.

FAQs (Frequently Asked Questions)

Q: Can I use pre-shredded cheese?
A: While convenient, pre-shredded cheese often contains cellulose, which can prevent it from melting as smoothly as freshly grated cheese. Freshly grated is always recommended for best results.

Q: How do I prevent the onions from burning while caramelizing?
A: Stir the onions frequently and adjust the heat as needed. If they start to stick, add a tablespoon or two of water or stock to deglaze the pan and keep them moist.

Q: Can I use different types of pasta?
A: Absolutely! Elbow macaroni, ziti, and fusilli are all great choices, but feel free to experiment with other shapes like shells or cavatappi.

Q: What’s the best way to reheat leftovers?
A: For best results, reheat in a preheated oven at 350°F (175°C) until heated through. Add a splash of milk or cream to restore moisture. Microwaving is also an option, but the texture may be slightly different.

Q: Can I add other vegetables to the onion mixture?
A: Yes! Sautéed mushrooms or a pinch of thyme would be wonderful additions.
