  • 1 cup chicken broth
  • 1 cup freshly grated Parmesan cheese
  • 1 cup shredded mozzarella cheese
  • 1 cup shredded cheddar cheese
  • 2-3 tablespoons Cajun seasoning adjust to taste
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon smoked paprika
  • Salt to taste
  • Black pepper to taste
  • 1 pound cooked chicken, sausage, or shrimp optional
  • Fresh parsley, chopped for garnish

Equipment

  • large pot
  • Large skillet or saucepan
  • Cheese grater
  • Measuring cups
  • Measuring spoons
  • whisk
  • colander

Method
 

  1. Bring a large pot of salted water to a boil.
  2. Add the rigatoni pasta and cook according to package directions until al dente.
  3. Reserve about 1 cup of pasta water before draining.
  4. Drain the pasta and set aside.
  5. In a large skillet or saucepan, melt the butter over medium heat.
  6. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.
  7. Slowly pour in the heavy cream, whisking continuously to prevent lumps.
  8. Gradually add the chicken broth, still whisking.
  9. Bring the sauce to a simmer, then reduce heat to low.
  10. Stir in the Parmesan cheese, mozzarella cheese, and cheddar cheese. Continue stirring until all the cheese is melted and the sauce is smooth and creamy.
  11. Add the Cajun seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper. Taste and adjust seasonings as needed.
  12. Add the cooked rigatoni to the sauce and toss to coat evenly.
  13. If the sauce is too thick, add a little of the reserved pasta water until it reaches your desired consistency.
  14. If using, stir in the cooked chicken, sausage, or shrimp.
  15. Serve the Cajun Cheesy Rigatoni Parmesan Sauce immediately.
  16. Garnish with fresh parsley, if desired.

Notes

Adjust the amount of Cajun seasoning to your preference. Freshly grated Parmesan cheese is recommended for best flavor and melting quality. Reserve pasta water to help bind the sauce to the pasta. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat in the microwave or a saucepan, adding a splash of milk or broth if needed. To make it vegetarian, omit the meat and add vegetables like bell peppers, onions, mushrooms, and zucchini.
