Ingredients

Units Scale
  • 2 tbsp olive oil
  • 2 medium yellow onions, diced
  • 1 tsp kosher salt
  • 1 tsp granulated sugar
  • 1 lb (450 g) rigatoni (or pasta of your choice), cooked and drained
  • 4 tbsp butter, plus extra for the baking dish
  • 1/4 cup (60 ml) all-purpose flour
  • 3 cups (720 ml) whole milk
  • 8 oz (225 g) smoked cheese, shredded
  • 8 oz (225 g) sharp cheddar cheese, shredded
  • 1/2 tsp black pepper
  • 1/4 tsp cayenne pepper
  • 1/2 cup (120 ml) panko breadcrumbs
  • 1/4 cup (60 ml) grated Parmesan cheese
  • 2 tbsp chopped fresh parsley

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter.
  2. In a large skillet over medium heat, add the olive oil. Once hot, add the diced onions and a pinch of kosher salt. Cook, stirring occasionally, for about 10 minutes.
  3. Add the granulated sugar to the onions and continue to cook for another 20-25 minutes, stirring occasionally, until the onions are deeply caramelized and golden brown. Remove from heat and set aside.
  4. In a large saucepan, melt the butter over medium heat. Stir in the flour and cook for about 1 minute, until the mixture is bubbling.
  5. Gradually whisk in the milk, ensuring there are no lumps. Cook, stirring constantly, until the sauce thickens, about 5-7 minutes.
  6. Remove the saucepan from heat and stir in the smoked cheese and cheddar cheese until melted and smooth. Season with black pepper and cayenne pepper.
  7. Combine the cooked pasta, caramelized onions, and cheese sauce in a large bowl, mixing until the pasta is evenly coated.
  8. Transfer the mixture to the prepared baking dish. In a small bowl, combine the panko breadcrumbs, Parmesan cheese, and chopped parsley. Sprinkle evenly over the pasta.
  9. Bake in the preheated oven for 25 minutes, or until the top is golden brown and crispy.
  10. Let cool for a few minutes before serving. Enjoy your caramelized onion macaroni and cheese!
