Step-by-Step Instructions
Preparing the Shrimp
First, you need to season the shrimp. Take 1 pound of medium shrimp and place them in a bowl. Sprinkle 1 tablespoon of Cajun seasoning over the shrimp. Toss the shrimp until they are fully coated in the seasoning. This step adds a nice kick to the dish.
Next, heat 2 tablespoons of olive oil in a large pot or deep skillet over medium heat. Once the oil is hot, add the seasoned shrimp. Cook them for about 2 to 3 minutes. You want them to turn pink and opaque. Once they are done, remove the shrimp from the pot and set them aside.
Cooking the Base and Pasta
In the same pot, add 3 cloves of minced garlic. Sauté the garlic for about 30 seconds. It should smell fragrant but not burnt. Then, pour in 1 cup of heavy cream and 2 cups of chicken broth. Bring this mixture to a gentle simmer.
Now, it’s time to add the pasta. Place 8 ounces of fettuccine pasta into the pot. Make sure the pasta is fully submerged in the liquid. Cook it according to the package instructions, which is about 10 to 12 minutes. Stir the pasta occasionally to prevent it from sticking.
Combining Ingredients
When the pasta reaches al dente, stir in 1 cup of grated Parmesan cheese. Mix well until the cheese melts and becomes creamy. Next, add 1 cup of halved cherry tomatoes and 1 cup of spinach leaves to the pot. Stir gently until the spinach wilts and the tomatoes warm up.
Finally, return the cooked shrimp to the pot. Mix everything together gently. Season with salt and pepper to taste. Remove the pot from heat and let it sit for a couple of minutes. This allows the dish to thicken slightly before serving.
Tips & Tricks
How to Perfectly Cook Shrimp
To cook shrimp just right, start with fresh or thawed shrimp. Peel and devein them first. Toss the shrimp in Cajun seasoning to add a spicy kick. Heat olive oil in your pot over medium heat. Add the shrimp and cook for about 2–3 minutes. You want them to turn pink but not rubbery. Remove them once cooked and set aside. This keeps them juicy and full of flavor.
Ensuring Creamy Alfredo Sauce
For a creamy Alfredo sauce, use heavy cream and chicken broth. Bring the mixture to a gentle simmer, then add your fettuccine. Stir often for even cooking, about 10-12 minutes. Once the pasta is al dente, mix in grated Parmesan cheese. Stir until it melts and blends into the sauce. If the sauce is too thick, add more broth or cream to reach your desired consistency.
Serving Suggestions for Best Presentation
To serve your Cajun shrimp Alfredo, use wide bowls for a nice look. First, scoop the pasta into the bowl, then add shrimp and veggies. Top with freshly chopped parsley for color. A sprinkle of extra Parmesan adds elegance. This not only makes the dish look great but also enhances flavor. Enjoy your beautiful and tasty meal!

Variations
Vegetarian Cajun Alfredo Option
If you want a meat-free meal, try a vegetarian version. Swap the shrimp for firm tofu or chickpeas. Toss them with Cajun seasoning like you would with shrimp. Sauté them until golden. You get a tasty, hearty dish that everyone can enjoy.
Adding Vegetables for Extra Nutrition
Boost the health factor by adding veggies. Toss in bell peppers, zucchini, or mushrooms. Add them when you cook the garlic. This lets them soak up the flavor and cook down nicely. You will not only get more color but also more nutrients.
Using Different Pasta Types
Fettuccine is great, but you can use other pasta types. Try penne, rotini, or even whole wheat pasta. Just make sure to adjust the cooking time according to the package. Each type brings a new twist to the dish.

FAQs
