Ingredients
List of Ingredients with Measurements
- 8 oz fettuccine pasta
- 1 lb large shrimp, peeled and deveined
- 4 tablespoons unsalted butter
- 3 cloves garlic, minced
- 1 cup heavy cream
- 1 cup grated Parmesan cheese
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
- Fresh parsley, chopped, for garnish
- Zest of 1 lemon
Key Ingredient Notes
Fettuccine is the best pasta for this dish. Its flat shape holds the sauce well. Large shrimp work best because they are meaty and cook quickly. Unsalted butter gives you control over the salt level. Parmesan cheese adds a rich flavor. Garlic is the star, so use fresh, minced garlic for the best taste. Lemon zest brightens the dish and adds freshness.
Possible Substitutions
If you don’t have fettuccine, use spaghetti or penne. For shrimp, you can use scallops or chicken. In place of heavy cream, try half-and-half for a lighter version. If you want a vegan option, use coconut cream and a vegan cheese substitute. Fresh parsley adds color, but dried herbs can work in a pinch.

Step-by-Step Instructions
Cooking the Fettuccine
Start by boiling a large pot of salted water. Add 8 ounces of fettuccine pasta. Cook according to the package guide until it is al dente, usually about 8 to 10 minutes. When done, drain the pasta but save about 1 cup of the starchy water for later. This water helps thicken the sauce.
Sautéing the Shrimp
Next, grab a large skillet and set it over medium heat. Melt 2 tablespoons of unsalted butter in the skillet. Add 1 pound of peeled and deveined shrimp. Sprinkle salt, pepper, and 1 teaspoon of Italian seasoning over them. Cook the shrimp for 2 to 3 minutes on each side, until they turn pink and opaque. Once cooked, remove the shrimp and set them aside on a plate.
Making the Garlic Butter Sauce
In the same skillet, add the remaining 2 tablespoons of butter. Let it melt, then toss in 3 cloves of minced garlic. Sauté this mix for about 1 minute. Keep an eye on the garlic so it doesn’t burn; burnt garlic tastes bitter and spoils the dish.
Preparing the Alfredo Sauce
Now, pour in 1 cup of heavy cream. Increase the heat slightly to bring this to a gentle simmer. Once it simmers, add in 1 cup of grated Parmesan cheese. Stir this mix until the cheese melts completely. If the sauce feels too thick, add a bit of the reserved pasta water until it reaches your desired creaminess.
Combining Shrimp and Pasta
Reintroduce the cooked fettuccine and the sautéed shrimp back into the skillet. Toss everything together to coat the pasta and shrimp in that rich, creamy sauce. For a fresh kick, gently fold in the zest of 1 lemon.
Serving Suggestions
Remove the skillet from the heat. Taste the dish and adjust the seasoning with more salt and pepper, if you like. Serve your Garlic Butter Shrimp Alfredo hot. Garnish with freshly chopped parsley for a pop of color and flavor. Enjoy this simple yet tasty dish!
Tips & Tricks
How to Perfectly Cook Shrimp
To cook shrimp just right, start with large, fresh shrimp. Peel and devein them first. Heat your skillet on medium heat and melt 2 tablespoons of butter. Add the shrimp to the hot skillet. Cook each side for 2-3 minutes. Watch for their color change. They should turn pink and opaque. Overcooking makes shrimp tough, so keep an eye on them.
Ensuring a Creamy Alfredo Sauce
For a creamy sauce, use heavy cream. Pour it into the skillet after cooking the garlic. Heat it gently and bring it to a simmer. Then, add grated Parmesan cheese slowly. Stir until it melts completely. If the sauce is too thick, add reserved pasta water a bit at a time. This helps achieve the perfect texture.
Adjusting Flavor Profiles
To adjust flavors, taste your dish before serving. You may want more salt or pepper. Adding lemon zest at the end brightens the dish. You can also try fresh herbs like basil or thyme. They add a lovely aroma and depth. If you like heat, a pinch of red pepper flakes can spice things up.
Pro Tips
- Perfectly Cooked Pasta: Always cook your pasta until al dente for the best texture. It will continue to cook slightly when mixed with the sauce.
- Fresh Shrimp: Use fresh or high-quality frozen shrimp for optimal flavor. Look for shrimp that are firm and have a clean smell.
- Cheese Matters: For the best Alfredo sauce, use freshly grated Parmesan cheese instead of pre-grated. It melts better and enhances the flavor.
- Adjust Consistency: If your sauce is too thick, add reserved pasta water gradually until you reach your desired creaminess. This will help the sauce cling to the pasta.
Variations
Adding Vegetables
You can make Garlic Butter Shrimp Alfredo even better by adding vegetables. Try adding spinach, broccoli, or bell peppers.
- Spinach: Add fresh spinach to the skillet right before you mix in the shrimp and pasta. It wilts down nicely and adds color.
- Broccoli: Steam or blanch broccoli florets until bright green. Toss them with the pasta and shrimp for extra crunch and nutrients.
- Bell Peppers: Slice bell peppers and sauté them with the garlic for added sweetness and flavor.
Adding veggies not only makes the dish colorful but also boosts its health benefits.
Spicy Garlic Butter Shrimp Alfredo
For a spicy twist, you can add heat to your Garlic Butter Shrimp Alfredo.
- Red Pepper Flakes: Sprinkle in red pepper flakes while cooking the shrimp. Start with a small amount and add more based on your heat preference.
- Hot Sauce: Mix a dash of your favorite hot sauce into the Alfredo sauce. This will give it a nice kick.
- Jalapeños: Sauté sliced jalapeños with garlic for an extra layer of flavor.
This spicy version will wake up your taste buds!
Low-Carb Alternatives
If you want a lighter version, consider low-carb alternatives.
- Zoodles: Swap out fettuccine for zucchini noodles. They cook quickly and absorb flavors well.
- Shirataki Noodles: These noodles are very low in carbs and calories. They work well in creamy sauces.
- Cauliflower Rice: Serve your shrimp Alfredo over cauliflower rice for a unique and healthy twist.
These alternatives make the dish lighter but still very tasty!
