Why You'll Love This Recipe
About the Ingredients
12 oz (340g) fettuccine pasta
Use high-quality pasta for best texture. You can substitute with linguine or spaghetti — just adjust cooking time.
1 lb (450g) large shrimp, peeled and deveined
Choose 21-25 count shrimp. If frozen, thaw overnight in the fridge. You can use scallops or chicken as a protein swap.
6 cloves garlic, minced
Fresh garlic is essential. Pre-minced jarred garlic works in a pinch but use 1.5 times more.
2 cups (480ml) heavy cream
Heavy cream gives the sauce richness. For a lighter version, use half-and-half but expect a thinner sauce.
1 cup (100g) freshly grated Parmesan cheese
Grate your own from a block — pre-shredded contains anti-caking agents that can make the sauce grainy. Substitute with Pecorino Romano for a sharper flavor.
4 tbsp (56g) unsalted butter
Salted butter works too, just reduce added salt. You can use olive oil for a different flavor profile.
1/2 cup (120ml) dry white wine
Use a Sauvignon Blanc or Pinot Grigio. If you avoid alcohol, substitute with chicken broth and 1 tsp lemon juice.
1 tsp salt
Adjust to taste. Sea salt or kosher salt preferred.
1/2 tsp black pepper
Freshly ground is best. Adjust to your heat preference.
2 tbsp fresh parsley, chopped
For garnish. Dried parsley works but use 1 tbsp.
Tips & Tricks
Don't overcook the shrimp
They cook in just 2-3 minutes per side. Remove them as soon as they turn pink and opaque to keep them tender.
Avoid a grainy sauce
Always grate your Parmesan fresh and add it over low heat, stirring constantly. High heat can cause the cheese to clump.
Reserve pasta water
Before draining, scoop out 1 cup of starchy pasta water. If your sauce is too thick, add a splash to loosen it up without thinning flavor.
Pro Tips
Step-by-Step Instructions
1. Cook the pasta
Bring a large pot of salted water to a rolling boil (212°F/100°C). Add fettuccine and cook according to package directions until al dente, usually 10-12 minutes. Reserve 1 cup of pasta water, then drain and set aside.
2. Sear the shrimp
Pat shrimp dry and season with a pinch of salt and pepper. In a large skillet over medium-high heat (400°F/204°C), melt 2 tbsp butter. Add shrimp in a single layer and cook for 2-3 minutes per side, until pink and opaque. Remove to a plate.
3. Sauté garlic
Reduce heat to medium (350°F/177°C) and add remaining 2 tbsp butter. Add minced garlic and sauté for 1 minute, until fragrant but not browned (golden).
4. Deglaze with wine
Pour in the white wine and scrape up any browned bits from the bottom. Let it simmer for 2-3 minutes, until reduced by half and the alcohol cooks off.
5. Make the sauce
Lower heat to low (250°F/121°C) and pour in the heavy cream. Stir gently and bring to a simmer, about 2 minutes. Do not boil hard, or the cream may curdle.
6. Add Parmesan
Gradually whisk in the grated Parmesan cheese, a handful at a time, until smooth and melted. Continue stirring over low heat for 1-2 minutes until the sauce thickens slightly and coats the back of a spoon.
7. Combine everything
Add the cooked pasta and shrimp back into the skillet. Toss to coat evenly with the sauce. If the sauce is too thick, add reserved pasta water a splash at a time until desired consistency.
8. Season and serve
Taste and adjust salt and pepper. Garnish with fresh parsley. Serve immediately, as the sauce thickens as it cools.
Delicious Variations
Add Vegetables
Sauté 2 cups of spinach or broccoli florets with the garlic for extra nutrients and color.
Spicy Kick
Add 1/2 tsp red pepper flakes with the garlic for a subtle heat.
Chicken Alfredo
Swap shrimp with 2 boneless chicken breasts, sliced thin and cooked through in the same pan.
How to Store Creamy Garlic Shrimp Pasta with Alfredo Sauce
Refrigerator
Store in an airtight container for up to 3 days. The sauce may thicken; add a splash of milk or cream when reheating.
Freezer
Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat gently in a skillet over medium-low heat (300°F/149°C), stirring constantly. Add a splash of milk or pasta water to bring back the creamy texture.
Frequently Asked Questions
Q: Can I use pre-cooked shrimp?
Yes, but add them at the end to avoid overcooking. Just warm them through in the sauce for 2-3 minutes.
Q: Why is my Alfredo sauce grainy?
Graininess usually comes from pre-shredded cheese or high heat. Use freshly grated Parmesan and keep the heat low when adding it.
Q: Can I make this dairy-free?
Yes, use coconut cream and vegan butter, plus a dairy-free Parmesan alternative. The flavor will change slightly but still be delicious.
Q: How do I get a thicker sauce?
Let the sauce simmer longer to reduce, or add a slurry of 1 tsp cornstarch mixed with 2 tbsp water. Stir until thickened.
