Why This Recipe Works

Toasting the panko bread crumbs in the microwave added crunch without the risk of burning them under the broiler.

Before You Begin

Sprinkle with chopped fresh basil before serving.

Instructions

Heat 2 tablespoons oil in Dutch oven over medium heat until shimmering. Add onion and three-quarters of garlic and cook until softened, about 4 minutes. Add pasta, tomatoes, water, 1¾ teaspoons salt, and pepper flakes and bring to boil. Reduce heat to medium; cover; and simmer until pasta is tender, about 10 minutes, stirring occasionally.

Meanwhile, combine panko, remaining 1 tablespoon oil, remaining garlic, and remaining ¼ teaspoon salt in bowl. Microwave until golden brown, 2 to 3 minutes, stirring occasionally; set aside.

Adjust oven rack to middle position and heat broiler. Stir chicken into pasta and sprinkle mozzarella over top. Broil until mozzarella is melted and spotty brown, about 5 minutes. Sprinkle with reserved panko mixture. Serve.
