Pesto Alfredo Shrimp

There are two kinds of pasta nights. The ones where you open a jar and hope for a reliable, and the ones where dinner feels like you put in effort even though you did not. This Pesto Alfredo falls confidently into the second category.

You get the richness of a classic Alfredo, the freshness of Creamy Pesto, and juicy shrimp that cook in minutes. The result is a glossy, restaurant-level bowl of comfort that feels indulgent without being heavy, fussy, or overcomplicated. This is the kind of pasta that makes people think you followed a complicated Creamy Pesto recipe, then quietly went back for seconds.

What Makes This Pesto Alfredo So Good (And Worth Your Time)

This recipe works because every element is doing a clear job instead of just hanging out on the plate.

• Alfredo meets pesto, not competes with it. The cream and parmesan mellow the pesto's sharp edges instead of drowning them, giving you balance rather than overload.
• Shrimp cook separately and fast. This keeps them juicy and tender, not rubbery or lost in sauce.
• The sauce clings to the pasta. A bit of pasta water emulsifies everything, creating that silky finish you want in a proper Pesto Fettuccine Alfredo. The same technique is what gives dishes like this no-cream seafood carbonara pasta their glossy, restaurant-style finish.
• It tastes indulgent without feeling heavy. The pesto brings brightness that keeps the cream from tipping into “too much.”

What Goes Into Pesto Alfredo

This recipe keeps things simple but flavorful, with a handful of ingredients that come together to create a rich, vibrant sauce. You'll only need about 10 minutes from start to finish.

• Jumbo Shrimp: Choose fresh or thawed shrimp for a reliable texture. Tails on or off, your call.
• Basil Pesto: This brings bold herby flavor and a touch of nuttiness to the creamy sauce.
• Half and Half or Heavy Cream: Use half and half for a lighter feel, or heavy cream for ultra-rich, velvety results.
• Parmesan Cheese: Freshly grated parmesan melts into the sauce, adding salty depth and creaminess.

Note: Please see recipe card at the bottom for a full list of ingredients with measurements.

Add Ins And Swaps (If You're Feeling Extra)

If you want to tweak things without breaking the balance, here are options that actually make sense.

• Swap shrimp for salmon or chicken: Pan sear first, then proceed as written for the sauce.
• Add sun dried tomatoes: Finely sliced for little pops of sweetness and acidity.
• Use spinach or baby kale: Stir in right at the end so it wilts into the sauce without going soggy.
• Change the pasta shape: Linguine or tagliatelle work beautifully if fettuccine is not happening.

On the stove

1. Sauté Shrimp Heat butter in a skillet over medium-high heat. Add shrimp and tomatoes, seasoning with salt and pepper. Cook until the shrimp begins to turn pink.

1. Add Garlic Stir in the minced garlic and continue cooking for another minute, just until the garlic is fragrant and the shrimp is nearly cooked through.

1. Pour in the Sauce Ingredients Reduce the heat to low-medium. Add the pesto, half and half, and half of the parmesan cheese.

1. Simmer the Sauce Let the sauce gently simmer for 1-2 minutes until it thickens slightly and the cheese melts into the mixture.

1. Finish with Fresh Herbs Sprinkle in the chopped parsley or basil along with the remaining parmesan. Stir once more to blend the flavors together.

1. Serve and Enjoy Serve the creamy pesto shrimp immediately over pasta, rice, zucchini noodles, cauliflower rice, or steamed vegetables.

For a low-carb option, we love serving this creamy shrimp over zucchini noodles, cauliflower rice, or steamed veggies, just like we do in our Creamy Tuscan Scallops and Carbonara Shrimp Alfredo. If you're leaning into a comfort, go for pasta, rice, or even mashed potatoes to soak up the sauce.

Garlic Mushroom Chicken Bites is always a good idea, especially with something this saucy. A crisp green salad with lemon vinaigrette adds a fresh contrast. Or pair it with a grilled steak for any easy surf-and-turf dinner at home.

Pro Tips From Someone Who's Made This Too Many Times

• Do not overcook the shrimp. Pull them off the heat the moment they turn opaque and pink.
• Add pasta water gradually. You want the sauce to cling, not swim.
• Keep the heat low once the parmesan goes in to avoid grainy sauce.
• Taste before salting. Parmesan and pesto already bring salt to the party.

Recipe FAQ's

Yes, just make sure they're fully thawed and patted dry before cooking so they sear nicely and don't water down the sauce.

Store-bought basil pesto works great, but if you have homemade on hand, even better. Just be sure it's good quality pesto with fresh flavor.

You can use either half and half or heavy cream. Half and half makes it lighter, while heavy cream gives you a richer, thicker sauce.
