Recipe Overview

Prep Time: 15 minutes
Cook Time: 15 minutes
Total Time: 30 minutes
Servings: 4
Dietary Type: Not Gluten-Free

Ingredients

½ lb fettuccine
1 lb shrimp, peeled and deveined
6 tablespoons butter, divided
4 cloves garlic, minced
1 ½ cups half-and-half
1 ⅓ cups Parmesan cheese, grated
1 tablespoon flour
1 (16 ounce) box frozen chopped spinach, thawed and drained
Cajun seasoning, to taste
½ teaspoon fresh ground pepper (approximately)

Equipment Needed

Large pot for boiling pasta
Two skillets
Small bowl
Tongs

Instructions

Begin by heating a large pot of water for the fettuccine. Be sure to generously salt the water once it comes to a boil; this will season the pasta from the inside out.
While the water is heating, prepare the shrimp. Rinse, peel, and devein them if necessary. Pat them dry with a paper towel to ensure they sear properly.
In a small bowl, combine the flour and grated Parmesan cheese. Mix well and set aside. This mixture will help thicken the sauce.
Once the water is boiling, add the fettuccine and cook according to package directions, usually around 8-10 minutes, or until al dente.
While the pasta is cooking, prepare the sauce. In one skillet, melt 4 tablespoons of butter over medium heat. Add the minced garlic and sauté for about a minute, until fragrant, being careful not to burn it.
Add the thawed and drained spinach to the skillet with the garlic and butter. Stir frequently until the spinach is heated through and any excess moisture has evaporated.
While the spinach is heating, melt the remaining 2 tablespoons of butter in a separate skillet over medium to medium-high heat. Keep a close eye on this pan, as you don’t want the butter to burn.
Sprinkle the shrimp generously with Cajun seasoning. Add the seasoned shrimp to the skillet with the melted butter. Reduce the heat to medium and stir frequently. The shrimp will cook quickly, so it’s important to remove them from the heat as soon as they turn pink and the flesh is no longer translucent. Overcooked shrimp will become rubbery, so aim for perfectly cooked, tender shrimp. This should only take about 2-3 minutes.
Pour the half-and-half into the skillet with the spinach. Stir well to combine.
Slowly sprinkle the Parmesan/flour combination into the spinach and half-and-half mixture, stirring constantly to prevent lumps from forming. Ensure the flour is fully incorporated.
Reduce the heat to low, season with pepper, and stir occasionally. The sauce should begin to thicken slightly.
Once the fettuccine is cooked al dente, drain it well.
To serve, scoop a serving of fettuccine onto the center of each plate. Using tongs, give the whole bunch a twist to create a nice, neat pile.
Ladle a generous amount of sauce over the noodles and arrange the shrimp on top. Serve immediately.

Expert Tips & Tricks

Don’t overcook the shrimp! This is the most important tip for this recipe. Overcooked shrimp is rubbery and unpleasant. Cook just until pink and opaque.
Thaw the spinach properly: Make sure to squeeze out as much excess water as possible from the thawed spinach. This will prevent the sauce from becoming watery.
Grate your own Parmesan: Pre-grated Parmesan often contains cellulose, which can prevent it from melting smoothly into the sauce. Freshly grated Parmesan will result in a creamier, more flavorful sauce.
Add a splash of lemon juice: A squeeze of fresh lemon juice at the end adds a bright, tangy flavor that complements the creamy sauce and spicy shrimp.
Spice it up! Feel free to adjust the amount of Cajun seasoning to your liking. If you prefer a milder flavor, use less. For a spicier dish, add a pinch of red pepper flakes to the sauce.

Serving & Storage Suggestions

Serve this Spicy Shrimp and Spinach Fettuccine Alfredo immediately for the best flavor and texture. Garnish with a sprinkle of fresh parsley or a dusting of extra Parmesan cheese for a pop of color and added flavor. This dish pairs well with a crisp white wine, such as Sauvignon Blanc or Pinot Grigio, or a light, refreshing salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a saucepan over low heat, adding a splash of milk or half-and-half if needed to loosen the sauce. Avoid reheating in the microwave, as this can cause the shrimp to become rubbery. Freezing is not recommended, as the sauce may separate upon thawing.

FAQs (Frequently Asked Questions)

Q: Can I use fresh spinach instead of frozen?
A: Yes, you can use fresh spinach. You’ll need about 1 pound of fresh spinach, and be sure to wash it thoroughly and remove any tough stems. Sauté it in the garlic butter until wilted before adding the half-and-half.

Q: How can I prevent the sauce from being too thin?
A: Ensure you’ve drained the spinach thoroughly. If the sauce is still too thin, you can add a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) and stir until thickened.

Q: Can I make this dish ahead of time?
A: While the components of the dish can be made separately (sauce, shrimp, pasta), it is best to assemble and serve immediately. The sauce may thicken too much, and the shrimp can become rubbery when reheated.

Q: What’s the best way to reheat leftover pasta?
A: The best way is to reheat it in a skillet with a little milk or half-and-half over low heat, stirring frequently until heated through. This helps prevent the sauce from drying out.

Q: Can I use a different type of cheese?
A: While Parmesan is the traditional choice for Alfredo sauce, you could experiment with other hard, grating cheeses like Pecorino Romano or Asiago.
