Creating Chicken Riggies is straightforward and fulfilling. Follow these steps to make your delicious dish:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Cook the rigatoni according to the package instructions until al dente. Drain and set aside.

2. Sauté Chicken: In a large skillet, heat olive oil over medium heat. Add the chicken pieces, season with salt and pepper, and sauté until browned and cooked through, about 6-7 minutes. Remove the chicken from the skillet and set aside.

3. Sauté Vegetables: In the same skillet, add the diced onion and sliced bell peppers. Sauté until softened, about 5 minutes. Add the minced garlic and red pepper flakes, cooking for an additional minute until fragrant.

4. Add Tomatoes: Stir in the crushed tomatoes, and let it simmer for about 5 minutes, allowing the flavors to meld together.

5. Add Cream: Pour in the heavy cream and stir. Allow it to simmer gently, thickening slightly.

6. Combine Chicken: Return the cooked chicken to the skillet, stirring to coat with the sauce.

7. Add Pasta: Toss in the cooked rigatoni and grated Parmesan cheese, combining everything well. Cook for an additional 2-3 minutes, just until heated through.

8. Check Seasoning: Taste and adjust seasoning with salt and pepper as needed.

9. Serve: Remove from heat, and garnish with fresh basil if desired.

These clear steps will guide you through the process of preparing your incredibly delicious Chicken Riggies!
