There are certain meals that feel like a reward—dishes you crave after a long day, when comfort and indulgence matter more than speed. Creamiest One-Pan Shrimp Fettuccine Alfredo is exactly that kind of recipe. It’s the perfect choice for a cozy evening at home, an intimate dinner with loved ones, or anytime you want restaurant-quality pasta without the extra effort or cleanup.
This dish is inspired by classic Italian-American Alfredo, reimagined for modern home cooks who love rich flavors but appreciate simplicity. Cooking everything in one pan allows the pasta to absorb every bit of creamy goodness while the shrimp stay tender and flavorful. The result is a silky, luxurious sauce that clings to every strand of fettuccine—deeply satisfying, elegant, and surprisingly easy to prepare.
Why One-Pan Shrimp Fettuccine Alfredo Is So Special
What sets this recipe apart is the technique. Instead of boiling pasta separately and combining it with sauce later, everything cooks together in one pan. This method creates layers of flavor while saving time and reducing dishes.
The shrimp add natural sweetness and a delicate texture that balances the richness of the Alfredo sauce. Garlic, butter, cream, and cheese come together into a smooth, velvety base that feels indulgent without being overwhelming. Each bite delivers a harmony of savory depth and creamy comfort.
This recipe is ideal for busy weeknights when you want something impressive or weekend dinners when you want to treat yourself without stress.

Salt – 1 teaspoon (or to taste)

Step-by-Step Instructions
Season the Shrimp
Begin by preparing the shrimp properly, as this step lays the foundation for flavor and texture. Place the peeled and deveined shrimp on a clean kitchen towel or paper towels and gently pat them dry. Removing excess moisture is essential—it helps the shrimp sear rather than steam, ensuring a tender bite with light caramelization. Once dry, season the shrimp evenly with 1 teaspoon salt, ½ teaspoon black pepper, and 1 teaspoon Italian seasoning. Toss gently to coat all sides. This simple seasoning enhances the shrimp’s natural sweetness without overpowering the creamy Alfredo sauce that will follow. Set the shrimp aside while you prepare the pan.
Sauté the Shrimp
Heat a large, deep skillet over medium heat and add 1 tablespoon olive oil along with 1 tablespoon unsalted butter. The combination of oil and butter prevents burning while adding richness. Once the butter has melted and begins to lightly foam, carefully place the shrimp in a single layer. Cook for 1 to 2 minutes per side, just until the shrimp turn pink and opaque. Avoid overcooking at this stage, as the shrimp will return to the pan later. Overcooked shrimp can become rubbery, so remove them as soon as they are just done. Transfer the shrimp to a plate and set aside.
Build the Flavor Base
Without cleaning the pan, add the remaining 2 tablespoons of butter. The leftover bits from the shrimp add depth and flavor to the sauce. Once the butter melts, add the minced garlic. Stir continuously and cook for about 30 seconds, just until fragrant. Garlic burns quickly, so keep a close eye on it. This brief sauté releases aromatic oils that infuse the entire dish with warmth and savory richness, forming the backbone of the Alfredo sauce.
Add Liquids and Pasta
Slowly pour in the heavy cream and whole milk, stirring to combine with the butter and garlic. This blend creates a balanced base—rich yet smooth, creamy without being overly heavy. Once combined, add the uncooked fettuccine directly into the pan. Gently press the pasta down so it’s mostly submerged in the liquid. This one-pan technique allows the pasta to cook while absorbing the creamy flavors, resulting in a sauce that clings beautifully to every strand. Bring the mixture to a gentle simmer, avoiding a rapid boil.
Cook the Pasta
Cover the skillet and let the pasta cook for 10 to 12 minutes, stirring occasionally to prevent sticking. As the pasta cooks, it releases starch into the liquid, naturally thickening the sauce. Stirring ensures even cooking and helps distribute the sauce evenly. The fettuccine should become tender but not mushy, and the sauce should thicken to a silky consistency. If the sauce becomes too thick before the pasta is fully cooked, add a small splash of milk to loosen it.
Finish the Sauce
Reduce the heat to low before adding the Parmesan cheese. Gradually sprinkle in 1½ cups freshly grated Parmesan while stirring continuously. Lower heat is essential here—high temperatures can cause cheese to clump or separate. The cheese should melt smoothly into the sauce, creating a glossy, velvety texture. Taste and adjust seasoning if needed, adding a pinch of salt or pepper to balance the richness.
Return the Shrimp
Gently add the cooked shrimp back into the pan along with 1 tablespoon lemon juice and red pepper flakes if using. Stir carefully to coat the shrimp in the sauce. Simmer for 2 to 3 minutes, just long enough for the shrimp to warm through and absorb the creamy flavors. The lemon juice brightens the dish and balances the richness without overpowering it.
Garnish and Serve
Remove the pan from heat and sprinkle with freshly chopped parsley. Serve immediately while the sauce is at its creamiest. This final touch adds freshness, color, and a subtle contrast to the rich Alfredo sauce, completing the dish beautifully.

Frequently Asked Questions
1. Can I use frozen shrimp for this recipe?
Yes, frozen shrimp work well as long as they are fully thawed and patted dry before cooking. Excess moisture can water down the sauce, so removing as much liquid as possible is key. Thawed shrimp still provide excellent texture and flavor when cooked correctly, making them a convenient option for busy home cooks.
2. How do I prevent the Alfredo sauce from becoming grainy?
Grainy sauce is usually caused by overheating or using pre-shredded cheese. Always lower the heat before adding Parmesan and stir gently. Freshly grated cheese melts smoothly and integrates better into the cream, resulting in a silky, luxurious sauce.
3. Can I make this dish ahead of time?
While Alfredo is best served fresh, you can make it ahead and reheat gently. Add a splash of milk or cream when reheating over low heat, stirring constantly. Avoid high heat, as it can cause the sauce to separate and the shrimp to become rubbery.
4. What can I substitute for heavy cream?
You can use a combination of whole milk and a small amount of cream cheese for richness. While the sauce may be slightly less thick, it will still be creamy and flavorful. Keep in mind that substitutions can affect texture, so gentle heat and constant stirring are essential.
