Preparation

Step 1

Preheat oven to 375 degrees F. Butter a 9”x13” baking dish.
In a large pot of salted, boiling water, cook macaroni until al dente. Drain and set aside.
In a large saucepan, melt 1 stick butter. Sprinkle over flour and cook until slightly golden, 2-3 minutes. Pour in milk and whisk until combined. Season with mustard powder, salt, and pepper. Let simmer until starting to thicken, about 5 minutes.
Remove pan from heat and whisk in cheddar, then gruyere, and then 1 cup Parmesan. Continue whisking until melted and smooth. Stir in cooked macaroni and transfer to prepared baking dish.
In a small bowl, combine remaining Parmesan with Panko and olive oil. Sprinkle mixture over macaroni, then season with more black pepper.
Bake until bubbly and golden, 25-30 minutes.
Garnish with parsley. Let sit 10 minutes before serving.
