Smoked Sausage Cajun Alfredo is a rich and creamy fettuccine dish with a bold Cajun kick. This recipe combines tender pasta with smoky sausage, Cajun seasoning, and crushed red pepper, creating a deliciously spicy variation of classic Alfredo. The smoky sausage pairs perfectly with the creamy sauce, and the entire dish comes together in about 30 minutes—perfect for a quick and satisfying meal!

Key Ingredients & Substitutions
- Pasta: Fettuccine is a great choice for holding onto the rich Alfredo sauce, but you can use any pasta you have on hand. For a fun twist, try homemade pasta!
- Smoked Sausage: Andouille sausage works beautifully here, but you can swap it for turkey sausage, chorizo, or kielbasa. Since it’s already cooked, it only needs a quick heat-through.
- Heavy Cream: This creates a luscious Alfredo base. For a lighter option, use half-and-half or whole milk.
- Cajun Seasoning: Adds bold, spicy flavor. Homemade Cajun seasoning will give you the best taste! Adjust the amount to suit your spice preference.
- Crushed Red Pepper: Enhances the heat. If Cajun seasoning alone is spicy enough for you, feel free to leave this out—or add extra for more kick!
- Parmesan Cheese: Freshly grated Parmesan melts best and gives the sauce a rich, cheesy flavor. Don’t forget extra for topping!
Adding Vegetables
We sometimes like to add veggies to the Smoked Sausage Cajun Alfredo for extra texture and flavor! Try sautéed bell peppers for color, spinach for earthiness, broccoli for crunch, zucchini for a tender bite, or mushrooms for a savory kick. Feel free to get creative with your favorite veggies—just be sure to adjust cooking times so everything is perfectly cooked before mixing them into the dish.
Storing & Reheating Smoked Sausage Cajun Alfredo
To store leftovers, allow the dish to cool to room temperature, then transfer it to an airtight container. Keep it refrigerated for up to 3-4 days. When reheating, use the stovetop over low heat or the microwave, adding a splash of cream or milk to loosen the sauce if needed.
Can You Freeze Smoked Sausage Cajun Alfredo?
Yes! This dish can be frozen, though the texture may change slightly when reheated. To freeze:
- Let it cool completely.
- Store in a freezer-safe container for 2-3 months.
- Thaw in the refrigerator overnight before reheating.
While the sauce might thicken after freezing, a little extra cream or milk will bring it back to life. Enjoy!
