This pasta bake is a weeknight dinner staple in my household: a garlic and cheesy pasta casserole with chicken that feeds a crowd. This is an easy recipe; only one dish required (just the baking dish) and everything is cooked at the same time in the oven. No need to boil the pasta or cook the chicken beforehand.
Set the oven to 400 F. Spray cooking oil on a 9 x 13 inch casserole pan.
Add and distribute all of the casserole ingredients onto the pan. Stir so that the ingredients are mixed.
Tightly cover the pan with two layers of foil, and place in the oven to bake until the pasta and chicken are cooked, about 50 minutes.
Remove the pan from the oven and turn the oven up to broil. Prepare the herb topping by mixing all of the topping ingredients together.
Remove the foil from the pan. Distribute the herb topping over the casserole. Place the uncovered pan back in the oven and let it broil until the topping is browned and crispy, about 5 minutes.
Let the casserole cool before scooping into it, about 10 minutes.
