Key Ingredients & Substitutions
Fettuccine Pasta: Fettuccine is a classic choice for Alfredo. If you don’t have it, spaghetti or tagliatelle works well too. For a gluten-free option, try gluten-free pasta or even zucchini noodles!
Shrimp: Large shrimp really make this dish shine! If you’re allergic or don’t like shrimp, you can substitute with chicken or tofu for a different but delicious experience.
Cajun Seasoning: A great blend that adds amazing flavor. If you don’t have it on hand, mix paprika, garlic powder, onion powder, cayenne pepper, and thyme instead. You control the spice level!
Heavy Cream: For a lighter version, use half-and-half or evaporated milk. This will still give you a creamy texture, though it may be a bit lighter than traditional Alfredo.
How Do I Make Sure My Sauce is Creamy and Smooth?
To achieve a perfect creamy Alfredo sauce, focus on a few key techniques. Start by combining the heavy cream and garlic over low heat. This helps the flavors meld without boiling.
- Gradually add the Parmesan cheese while stirring continuously. This helps ensure it melts evenly without clumping.
- Don’t rush the heat! Keep it on low to medium to prevent the sauce from separating.
- If the sauce is too thick, you can always add a splash of pasta water to reach your desired consistency.
These tips will help you enjoy a wonderfully creamy sauce that clings to your pasta and shrimp perfectly!

Step-by-Step Instructions:
1. Cook the Pasta:
Start by boiling salted water in a large pot. Add the fettuccine pasta and cook according to the package instructions until it’s al dente. Once done, drain the pasta and set it aside. We want that perfect pasta for our dish!
2. Season the Shrimp:
In a mixing bowl, toss the peeled and deveined shrimp with Cajun seasoning until they’re well coated. This will give the shrimp a nice kick!
3. Cook the Shrimp:
In a large skillet, heat the olive oil over medium-high heat. Add the seasoned shrimp and cook for about 2-3 minutes on each side until they turn pink and are fully cooked. Once cooked, remove the shrimp from the skillet and set them aside.
4. Make the Garlic Butter:
In the same skillet, reduce the heat to medium and melt 2 tablespoons of butter. Add the minced garlic and sauté for about 1 minute, stirring until fragrant. Be careful not to burn the garlic!
5. Prepare the Creamy Sauce:
Lower the heat and slowly pour in the heavy cream, stirring gently. Let this simmer for about 3-4 minutes to allow the flavors to blend together.
6. Add Cheese and Final Touches:
Next, stir in the freshly grated Parmesan cheese and the remaining 2 tablespoons of butter until the sauce is smooth and creamy. Season with salt and pepper to taste—this is where you can adjust the flavors to your preference!
7. Combine Pasta with Sauce:
Now it’s time to bring it all together! Add the drained fettuccine into the creamy sauce and toss until all the noodles are coated evenly.
8. Return the Shrimp:
Gently add the cooked shrimp back into the skillet, mixing them with the pasta and creamy sauce. Let the ingredients warm together for a minute.
9. Add Bacon (Optional):
If you’re using bacon, sprinkle the chopped, cooked bacon over the top for an extra flavor boost.
10. Garnish and Serve:
Finally, garnish your Cajun Shrimp Alfredo with freshly chopped parsley for a nice pop of color. Serve immediately and enjoy this creamy, spicy dish that brings the taste of New Orleans right to your table!

Can I Use Frozen Shrimp for This Recipe?
Yes, you can use frozen shrimp! Just make sure to thaw them beforehand for even cooking. You can thaw shrimp overnight in the fridge, or if you’re short on time, place them in a sealed bag and submerge them in cold water for about 15-20 minutes.
What If I Don’t Have Fettuccine Pasta?
No problem! While fettuccine is traditional, you can use any pasta you have on hand. Spaghetti, linguine, or even penne will work just fine. Just adjust the cooking time according to the pasta type you choose.
Can I Make This Recipe Creamier?
Absolutely! For an extra creamy Alfredo sauce, you can add more heavy cream or an additional tablespoon of butter. Just remember to re-season with salt and pepper after adding more ingredients if needed.
How Can I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of milk or cream to the pasta as it warms to help rehydrate the sauce and keep it creamy.
