Mac & Cheese for One

Coat the bottom of a small saucepan with cooking spray; heat over medium heat. Add panko; cook, stirring often, until golden, 30 to 45 seconds. Transfer to a plate. Let the pot cool slightly, then wipe it clean. 

Add 2 cups water to the pot; bring to a boil over high heat. Add pasta and cook according to package instructions. Drain the pasta; transfer to a bowl and cover to keep warm. Wipe out the pot.

Heat oil in the pot over medium heat. Stir in flour; cook, whisking constantly, until golden and toasty, 30 to 45 seconds. Gradually whisk in milk; cook, whisking constantly, until the sauce simmers and thickens, 1 to 2 minutes. Remove from heat and stir in cheese, salt, Worcestershire and garlic powder. Stir in the pasta. Top with the toasted breadcrumbs just before serving.
