Recipe Information
Ingredients
- 12 oz elbow macaroni
- 4 tbsp unsalted butter
- 1 large sweet onion
- 3 tbsp all-purpose flour
- 3 cups whole milk
- 2 cups sharp cheddar cheese, shredded
- 1 cup gruyere cheese, shredded
- 0.5 cup parmesan cheese, grated
- 1 tsp salt
- 0.5 tsp black pepper
- 1 cup panko breadcrumbs
- 1 tbsp olive oil
- 1 tsp fresh thyme leaves (optional, for garnish)
Instructions
Bring a large pot of salted water to a boil. Cook the elbow macaroni according to package instructions until al dente. Drain and set aside.
In a large skillet, melt 2 tablespoons of butter over medium heat. Thinly slice the sweet onion and add it to the skillet. Cook, stirring occasionally, for 15-20 minutes until the onion is golden brown and caramelized. Remove from heat and set aside.
Preheat your oven to 375°F (190°C).
In a large saucepan, melt the remaining 2 tablespoons of butter over medium heat. Add the flour and whisk for 1-2 minutes until a roux forms.
Gradually whisk in the milk, ensuring no lumps remain. Cook for 3-4 minutes, stirring constantly, until the mixture thickens.
Lower the heat to medium-low and stir in the sharp cheddar, gruyere, and parmesan cheeses. Mix until the cheese melts and the sauce is smooth.
Add the salt and black pepper to the cheese sauce. Taste and adjust seasoning if necessary.
Stir the drained macaroni into the cheese sauce until fully coated, then gently fold in the caramelized onions.
Transfer the mac and cheese mixture to a greased 9x13 inch baking dish, spreading it out evenly.
In a small bowl, mix the panko breadcrumbs with the olive oil. Sprinkle the breadcrumb mixture evenly over the mac and cheese.
Bake in the preheated oven for 15-20 minutes, or until the top is golden and bubbly.
Let cool for 5 minutes before serving. Garnish with fresh thyme leaves, if desired.
