🥄 INGREDIENTS LIST AND SUBSTITUTION
OLIVE OIL:
Adds richness and helps brown the sausage. It can be swapped with vegetable oil or butter.
SMOKED SAUSAGE:
Andouille or any smoked sausage works! Turkey or chicken sausage can be a lighter option.
ONION:
Shallots or leeks can be used instead.
CUJAN SPICE:
Home-made or store-bought. You can swap this for smoked paprika.
FRESH GARLIC:
Garlic powder can work in a pinch.
LOW-SODIUM CHICKEN BROTH:
Or use low-sodium vegetable broth.
SUGAR:
Sugar balances out the acidity of the tomatoes and enhances the overall flavor (optional).
HEAVY CREAM:
It makes the sauce rich, and creamy and gives it that alfredo vibe. You can use half-and-half instead.
SPAGHETTI:
You can swap for any short pasta like rigatoni or rotini. A little tip when using spaghetti, break it in half and add it to the sauce.
SHREDDED CHEESE:
Monterey Jack cheese melts smoothly into the sauce. Cheddar or mozzarella work well too.

Notes
Don’t have smoked sausage? Use any variety you like for a similar depth of flavor.
Want a thicker sauce? Let it simmer uncovered for a few extra minutes before adding the cream.
Like it extra spicy? Add a pinch of cayenne or extra Cajun seasoning.
Not a fan of Spaghettie? Swap it for fettuccine, penne, or any pasta you prefer.
Got leftovers? Lucky you! This pasta tastes even better the next day. Just reheat with a splash of broth or cream and enjoy.
Can this be made ahead? Yes! Cook as directed, let it cool and store in an airtight container.
Fridge: Store leftovers in an airtight container for up to 3 days.
Freezer: Not ideal due to the creamy sauce, but you can freeze it for up to 1 month. Thaw overnight in the fridge and reheat gently.
