Stuff You’ll Need
- 3 tablespoons extra-virgin olive oil, divided
- 1 small onion, finely chopped
- 3 garlic cloves, minced
- 12 ounces (about 3¾ cups) penne
- 1 can (28 ounces) crushed tomatoes
- 2¾ cups water
- 1¾ teaspoons table salt, divided
- ½ teaspoon red pepper flakes
- ½ cup panko bread crumbs
- 2½ pounds rotisserie chicken, skin and bones discarded, meat shredded (about 3 cups)
- 1¾ cups whole-milk mozzarella cheese, shredded
Stuff to Know Before Baking
For a fresh finish, sprinkle with chopped basil before serving.
Start the Base
Heat 2 tablespoons of oil in a Dutch oven over medium heat until shimmering.
Add the onion and three-quarters of the garlic. Cook until softened, about 4 minutes.
Simmer the Pasta
Stir in the penne, crushed tomatoes, water, 1½ teaspoons salt, and red pepper flakes.
Bring to a boil, then reduce to medium heat. Cover and simmer, stirring occasionally, until the pasta is tender, about 10 minutes.
Make the Crunchy Topping
In a small bowl, combine the panko, remaining tablespoon of oil, remaining garlic, and a pinch of salt.
Microwave in short bursts, stirring occasionally, until golden brown, about 2 to 3 minutes.
Add Chicken and Broil
Adjust the oven rack to the middle and preheat the broiler.
Stir the shredded chicken into the pasta, then sprinkle the mozzarella evenly over the top.
Broil until the cheese is melted and golden brown in spots, about 5 minutes.
Finish and Serve
Top with the toasted panko mixture. Serve immediately.
