Equipment

  • Large deep skillet or Dutch oven with lid
  • Wooden spoon or spatula
  • Knife and cutting board
  • Measuring Cups and Spoons
  • Cheese grater (optional)

Ingredients
  

  • 12 oz Andouille or smoked sausage, sliced
  • 1 medium onion, finely chopped
  • 1 bell pepper (any color), diced
  • 3 cloves garlic, minced
  • 2 tbsp Cajun seasoning (adjust to taste)
  • 8 oz pasta (penne, rigatoni, or shells recommended)
  • 3 cups chicken broth (or as needed)
  • 1 cup heavy cream
  • 1 cup shredded Parmesan or sharp cheddar cheese
  • Salt and pepper, to taste
  • Fresh parsley or green onions for garnish (optional)

Instructions
 

  • Brown sausage in a large skillet over medium-high heat until crisp, about 5-7 minutes. Remove some fat if excessive, but leave enough to sauté veggies.
  • Add onions, bell peppers, and garlic to the pan; sauté until softened and fragrant, about 4-5 minutes.
  • Sprinkle Cajun seasoning over sausage and veggies; toast for 1 minute, stirring constantly.
  • Deglaze pan with a splash of chicken broth or white wine, scraping up browned bits.
  • Add uncooked pasta and remaining broth; bring to a simmer. Stir frequently to prevent sticking. Cook until pasta is al dente and most liquid is absorbed, about 10-12 minutes.
  • Reduce heat to low; stir in cream and cheese until sauce is smooth and coats pasta. Adjust seasoning with salt and pepper.
  • Garnish with parsley or green onions and serve hot.

Notes

  • For a lighter version, use half-and-half instead of heavy cream.
  • Feel free to add greens like spinach or kale during the last few minutes of cooking.
  • Adjust spice level by increasing or decreasing Cajun seasoning and cayenne.
  • Leftovers store well refrigerated for up to 4 days and reheat best on the stovetop with a splash of broth.
  • This dish freezes best without cream; add cream fresh when reheating.
