Ingredients
Scale:
8 ounces elbow macaroni (or any pasta of your choice)
2 large onions, thinly sliced (preferably yellow or sweet onions)
2 tablespoons olive oil
1 tablespoon butter
1 teaspoon salt
2 tablespoons butter (for cheese sauce)
2 tablespoons all-purpose flour
2 cups whole milk
1 teaspoon garlic powder
1/2 teaspoon black pepper
1/4 teaspoon nutmeg
2 cups shredded Gruyère cheese
1 cup shredded sharp cheddar cheese
1 cup panko breadcrumbs
1/2 cup grated Parmesan cheese
2 tablespoons melted butter (for topping)
Instructions
In a large pot, bring salted water to a boil. Cook the pasta according to package instructions until al dente, about 7-9 minutes. Drain and set aside, reserving some pasta water if needed.
In a large skillet over medium heat, add the olive oil and butter. Once melted, add the sliced onions and salt. Cook, stirring occasionally, until the onions are deeply golden brown and caramelized, about 20-25 minutes. Remove from heat and set aside.
In a saucepan, melt 2 tablespoons of butter over medium heat. Stir in the flour and cook for 1-2 minutes until lightly golden. Gradually whisk in the milk, ensuring there are no lumps. Cook until the sauce thickens, about 5-7 minutes.
Once the sauce has thickened, stir in garlic powder, black pepper, nutmeg, Gruyère, and cheddar cheese. Mix until the cheese is fully melted and the sauce is creamy.
In a large mixing bowl, combine the cooked pasta, caramelized onions, and cheese sauce. Stir until the pasta is evenly coated.
Preheat your oven to 350°F (175°C). Transfer the pasta mixture to a greased baking dish.
In a small bowl, mix panko breadcrumbs with grated Parmesan and melted butter. Sprinkle this mixture evenly over the mac and cheese.
Bake in the preheated oven for about 25-30 minutes, or until the top is golden brown and crispy.
Allow the dish to cool for a few minutes before serving. Enjoy your French Onion Mac and Cheese warm!
