In a large, deep Dutch oven, add the uncooked pasta, tomatoes, onion, peppers, broth, garlic, Cajun seasoning, crushed red pepper flakes, salt, and pepper. Stir combine.
Bring the ingredients to a boil over high heat. Then, cover, and reduce the heat to medium. Simmer for 12-15 minutes or until the pasta is al dente, stirring halfway through.
Stir in the grated Parmesan cheese, shrimp, sausage, cilantro, and heavy cream until well combined.
Garnish with Parmesan cheese shavings, if desired. Serve warm!
Store in an airtight container in the fridge for up to 3 days.
