This is a fancy macaroni and cheese recipe that I came up with. The sweet caramelized onions and the sharp cheese flavors really complement each other. This recipe requires a little more work, but it's worth it. Vegetable broth can be substituted for chicken broth to make this a vegetarian dish. Enjoy!!

Ingredient Checklist


Instructions Checklist
  • Preheat oven to 400 degrees F (200 degrees C). Butter a 9x13-inch baking dish.

  • Melt 2 tablespoons of the butter in a large skillet over medium heat. Add onions, sugar, and salt. Cook, stirring often, until onions are caramel colored, 15 to 20 minutes. If mixture is too dry, add an additional tablespoon of butter. Set aside.

  • Bring a large pot of lightly salted water to a boil. Add macaroni and cook until al dente, 8 to 10 minutes. Drain, cover and set aside.

  • Melt 1 tablespoon of the butter in a small skillet over medium heat. Stir in the bread crumbs and toast lightly for a few minutes, stirring constantly.

  • Melt the remaining 3 tablespoons butter in a large pot over medium heat. Dissolve the dry mustard in an equal amount of water and add to the pot along with the garlic, and cayenne pepper. Stir until fragrant, about 30 seconds. Sprinkle in the flour and cook until golden, about 1 minute. Slowly whisk in the milk and broth. Bring to a simmer stirring constantly until the mixture is slightly thickened, about 5 minutes.

  • Remove the pan from the heat and stir in the Cheddar and Parmesan cheeses until melted. Stir in the onions and season with salt and pepper. Add the drained macaroni and stir until blended. Pour into the prepared baking dish and top with bread crumbs.

  • Bake until golden brown and bubbling around the edges, 25 to 30 minutes. Let cool for 10 minutes before serving.
