2-3 boneless, skinless chicken
breasts, cut into 1-inch squares
Table salt and ground black pepper
3 tablespoons olive oil
1 medium onion, minced
4 medium cloves garlic, minced
½ teaspoon dried oregano
¼ teaspoon red pepper flakes
12 ounces ziti
4¼ cups water
2½ cups low-sodium chicken broth
4-5 cups broccoli florets (depending
on how much broccoli you want)
½ cup oil-packed sun-dried tomatoes,
rinsed and chopped coarse
¾ cup heavy cream
¾ cup grated parmesan cheese or
1½ tablespoons fresh lemon juice
Season the chicken with salt and pepper. Heat 2 tablespoons of the oil in a 12-inch nonstick skillet over medium-high heat until just smoking. Add the chicken in a single layer and cook for 1 minute without stirring. Stir the chicken and continue to cook until most, but not all, of the pink color has disappeared and the chicken is lightly browned around the edges, 1 to 2 minutes longer. Transfer the chicken to a clean bowl and set aside.
Add the remaining tablespoon of oil, onion, and 1/2 teaspoon salt to the skillet. Return the skillet to medium-high heat and cook, stirring often, until the onion is softened, 2 to 5 minutes. Stir in the garlic, oregano, and pepper flakes, and cook until fragrant, about 30 seconds.
Add the pasta, 3 cups of the water, and the broth. Bring to a boil over high heat and cook until the liquid is very thick and syrupy and almost completely absorbed, 12 to 15 minutes, stirring occasionally.
Add the broccoli, sun-dried tomatoes, and the remaining 1 1/4 cups water. Cover, reduce the heat to medium, and cook until the broccoli turns bright green and is almost tender, 2-3 minutes.
Uncover and return the heat to medium-high. Stir in the cream, parmesan, and reserved chicken with any accumulated juices and continue to simmer, uncovered, until the sauce is thickened and the chicken is cooked and heated through, 1 to 2 minutes. Off the heat, stir in the lemon juice and season with salt and pepper to taste. Serve, passing more grated parmesan at the table, if desired.
