Method
Pasta Preparation
Cook the Pasta
In a large pot, bring salted water to a boil. Add the elbow macaroni and cook according to package instructions until al dente. Drain and set aside.
Onion Mixture
Caramelize the Onions
In a large skillet, heat the butter and olive oil over medium heat. Add the chopped yellow onions, salt, and sugar. Cook for about 20-25 minutes, stirring frequently, until the onions become golden and caramelized. Season with black pepper to taste. Remove from heat and set aside.
Cheese Sauce
Make the Cheese Sauce
In a medium saucepan, melt 2 tablespoons of butter over medium heat. Whisk in the all-purpose flour and cook for 1-2 minutes. Gradually add the milk, whisking continuously to avoid lumps. Bring to a simmer and cook until thickened, about 3-5 minutes. Remove from heat and stir in the sharp cheddar cheese, Gruyère cheese, Dijon mustard, and Worcestershire sauce until smooth.
Combine and Bake
Combine Ingredients
In a large mixing bowl, combine the cooked pasta, caramelized onions, and cheese sauce. Mix until evenly coated.
Prepare for Baking
Preheat the oven to 350°F (175°C). Transfer the mac and cheese mixture into a greased 9x13-inch baking dish.
Add Topping
In a small bowl, mix the breadcrumbs and Parmesan cheese together. Sprinkle this mixture evenly over the mac and cheese. If desired, sprinkle fresh parsley on top.
Bake
Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and the mac and cheese is bubbly.
