Ingredients
Method
- Cook spaghetti in salted boiling water 1 to 2 minutes less than package directions. Drain and set aside.
- Melt 2 tbsp butter in a skillet over medium heat. Whisk in flour and cook 1 minute. Slowly whisk in broth, milk, garlic powder, and onion powder. Simmer until thickened, 3 to 4 minutes. Off heat, stir in 1 cup Monterey Jack, salt, and pepper.
- Preheat oven to 375°F (190°C). Toss drained spaghetti, chicken, and sauce in a large bowl until evenly coated.
- Spread into a greased 9×13-inch dish. Top with remaining 1 cup cheese, then panko. Drizzle with 1 tbsp melted butter. Bake 25 minutes, then broil 2 minutes until golden.
- Rest 5 minutes, then scoop and serve hot.
Notes
Rotisserie chicken keeps this quick; shred it while the pasta water heats up. If the casserole has been refrigerated, add 5 to 7 minutes to the bake time to warm it through. The broiler step is optional but gives the best crunchy top, so do not skip it.
