Cooking Instructions

  1. 1

    Cook the Pasta

    In a large pot of salted boiling water, cook the macaroni according to package instructions until al dente. Drain and set aside.

  2. 2

    Caramelize the Onions

    In a large skillet, melt 2 tablespoons of butter over medium-low heat. Add the sliced onions and cook, stirring occasionally, for about 20-25 minutes until they are golden brown and caramelized. Remove from heat and set aside.

  3. 3

    Make the Cheese Sauce

    In the same skillet, melt the remaining 2 tablespoons of butter. Stir in the flour and cook for 1-2 minutes to create a roux. Gradually whisk in the milk, stirring constantly until the mixture thickens. Add the cheddar and Parmesan cheeses, salt, black pepper, and garlic powder. Stir until the cheese is melted and the sauce is smooth.

  4. 4

    Combine and Bake

    Preheat the oven to 350°F (175°C). In a large bowl, combine the cooked macaroni, cheese sauce, and caramelized onions. Mix well. Transfer to a greased baking dish and top with breadcrumbs. Bake for 20-25 minutes until the top is golden brown and bubbly.

  5. 5

    Serve

    Let it cool for a few minutes before serving. Enjoy your Caramelized Onion Mac n’ Cheese!
