Layering and Assembly

Crispy Topping Creation

Achieving the ideal golden-brown, crunchy breadcrumb and cheese topping that provides textural contrast while staying crispy even as the dish bakes.

Mastering French Onion Mac & Cheese Excellence

Caramelization Success: Don't rush the onion caramelizing process - low and slow is key for developing deep, sweet flavors. If onions start to stick, add a splash of water or broth to deglaze the pan.

Cheese Selection: Use freshly shredded gruyere rather than pre-shredded cheese for better melting and creamier texture. Pre-shredded cheese contains anti-caking agents that can make sauce grainy.

Make-Ahead Option: Assemble the entire dish up to 24 hours in advance without the topping, cover and refrigerate, then add topping and bake when ready to serve, adding 5-10 extra minutes to baking time.

Broth Substitution: For vegetarian version, use vegetable broth or mushroom broth instead of beef broth to maintain the deep savory flavor profile.

Texture Control: If sauce seems too thick, thin with additional milk or broth. If too thin, simmer longer before adding cheese or add an extra tablespoon of flour to the roux.

Leftovers Storage: Store covered in refrigerator for up to 4 days. Reheat in 350°F oven covered with foil, adding a splash of milk to restore creaminess.

Instructions

Begin caramelizing the onions by melting 4 tablespoons butter in a large Dutch oven over medium heat, add sliced onions, sugar, salt, and pepper, stirring occasionally for 30-35 minutes until deep golden brown and jammy.

While onions caramelize, bring a large pot of salted water to boil and cook elbow macaroni according to package directions until al dente, drain and set aside.

Preheat oven to 375°F and grease a 9x13 inch baking dish with butter or cooking spray.

In the same pot used for pasta, melt 6 tablespoons butter over medium heat, whisk in flour and cook for 2-3 minutes until golden and fragrant to create a roux.

Gradually whisk in milk, beef broth, and heavy cream, stirring constantly to prevent lumps, bring to a gentle simmer and cook for 5-7 minutes until sauce thickens enough to coat the back of a spoon.

Remove from heat and stir in 3 cups gruyere cheese, 1 cup parmesan, Dijon mustard, thyme, and garlic powder until cheese is completely melted and sauce is smooth and creamy.

Fold in cooked macaroni and caramelized onions, stirring until pasta is completely coated in cheese sauce, season with salt and pepper to taste.

Transfer mac and cheese mixture to prepared baking dish, spreading evenly across the pan.

Prepare topping by combining panko breadcrumbs with melted butter, 1 1/2 cups gruyere cheese, parmesan, and parsley in a bowl, then sprinkle evenly over mac and cheese.

Bake uncovered for 25-30 minutes until top is golden brown and bubbly, cheese is melted and edges are crispy.

Remove from oven and let rest for 5-10 minutes before serving to allow sauce to set slightly, garnish with additional fresh thyme if desired.
