1 ½ pounds boneless, skinless chicken breast, cut into 1 ½-inch pieces
1 teaspoon salt, divided
½ teaspoon pepper, divided
1 large red bell pepper, diced
1 large yellow onion, diced
3 cloves garlic, minced
1 28-ounce can crushed tomatoes
½ cup sliced drained hot cherry peppers
½ cup heavy cream
Directions
Bring a large pot of salted water to a boil, add the rigatoni, and cook according to package directions. Drain the pasta and set aside.
Meanwhile, in a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the chicken and sprinkle ½ teaspoon salt and ¼ teaspoon pepper onto the meat. Cook, stirring occasionally, until the chicken is completely cooked through. Transfer to a plate and set aside.
Add the remaining 2 tablespoons of olive oil to the same skillet, followed by the bell pepper, onion, garlic, and remaining salt and pepper. Cook, stirring frequently, until the vegetables soften, about 5-6 minutes.
Add the crushed tomatoes and cherry peppers to the skillet. Bring to a simmer and cook, stirring occasionally, until the sauce thickens slightly, about 5 minutes.
Mix in the cream until combined. Add the chicken and pasta and stir until coated. Top with Parmesan and parsley if desired, and serve.
