Ingredient Notes & Substitutions

Shrimp: You can also use chicken or sausage if you prefer. For a vegetarian twist, substitute shrimp with roasted mushrooms or zucchini.
Cajun Seasoning: Store-bought works fine, but homemade Cajun spice (paprika, garlic powder, cayenne, oregano) gives better control over heat.
Cheese: Parmesan adds saltiness while mozzarella gives that gooey stretch, don’t skip either!
Pasta Type: Any short pasta works, penne, rigatoni, or rotini hold sauce beautifully.
Cream Substitute: Half-and-half can be used for a lighter version.

Step-by-Step Instructions

Step 1 — Cook the Pasta

Bring a large pot of salted water to a boil and cook the pasta until just al dente. Drain and set aside, drizzling with a little olive oil to prevent sticking.

Save

Step 2 — Season and Sear the Shrimp

In a skillet, heat olive oil and butter over medium-high heat. Add shrimp, sprinkle Cajun seasoning, and cook for 2–3 minutes per side until they turn pink and slightly golden. Remove shrimp and set aside on a plate.

Save

Step 3 —Make the Alfredo Sauce

In the same pan, add minced garlic and sauté for 30 seconds until fragrant. Pour in heavy cream and chicken broth, stirring to combine. Lower the heat and slowly whisk in Parmesan cheese until melted and smooth. Add paprika and adjust seasoning.

Save

Step 4 —Combine Shrimp and Pasta

Add the cooked pasta to the sauce and toss well to coat every strand. Gently fold in the shrimp and half of the shredded mozzarella. Mix until evenly distributed.

Save

Step 5 —Bake to Perfection

Transfer the mixture to a greased baking dish. Sprinkle the remaining mozzarella cheese on top. Bake at 375°F (190°C) for 15–20 minutes or until bubbly and golden.

Save

Step 6 —Garnish and Serve

Once baked, let it cool slightly. Garnish with chopped parsley and a pinch of chili flakes if you like extra spice. Serve warm and enjoy that creamy Cajun perfection!

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven with a splash of milk to bring back the creaminess. Avoid freezing — dairy-based sauces tend to separate after thawing.

FAQs

bsolutely! If you’re short on time, you can skip the baking step. Just prepare the shrimp Alfredo on the stovetop, combine everything, and serve it straight from the pan. You’ll still get that creamy, spicy Cajun flavor, just without the golden cheesy crust on top.

A: Large or jumbo shrimp are perfect for this recipe because they stay juicy and meaty even after baking. Make sure they’re peeled and deveined for easy eating. You can use frozen shrimp too — just thaw and pat dry before cooking.

A: Definitely! Start with one tablespoon of Cajun seasoning, then taste the sauce before baking. If you prefer mild, cut it to half; for more kick, add chili flakes or a touch of hot sauce.

A: Penne or rigatoni are ideal because their ridges hold onto the sauce beautifully. However, you can also use fettuccine or even rotini, anything that clings to creamy sauce works like magic!
