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

Top shot of ingredients: Shrimp, grape tomatoes, half and half, garlic, parmesan cheese, basil pesto, salt, unsalted butter, parsley, and pepper.
  • Jumbo Shrimp: Choose fresh or thawed shrimp for the best 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.

How To Make Creamy Pesto Shrimp Alfredo

Shrimp and tomatoes, seasoned with salt and pepper in a skillet.
  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.
Garlic added to the shrimp and tomatoes.
  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.
Added pesto, half and half, and half of the parmesan cheese.
  1. Pour in the Sauce Ingredients Reduce the heat to low-medium. Add the pesto, half and half, and half of the parmesan cheese.
Shrimp and tomatoes with thick sauce.
  1. Simmer the Sauce Let the sauce gently simmer for 1-2 minutes until it thickens slightly and the cheese melts into the mixture.
Sprinkled in the chopped parsley with the parmesan over the creamy shrimp and tomatoes.
  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, I love serving this creamy shrimp over zucchini noodles, cauliflower rice, or steamed veggies, just like I do in my 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

Can I Use Frozen Shrimp Instead of Fresh?

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

What’s the Best Type of Pesto to Use?

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.

Can I Swap Out the Cream?

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.

Ingredients 
 

  • 2 tablespoons unsalted butter
  • 1 pound jumbo shrimp tails on or off
  • 4-5 cloves garlic minced
  • 4 ounces grape tomatoes
  • 1/2 cup basil pesto
  • 1 cup half and half or heavy cream, see notes
  • 1/2 cup parmesan cheese fresh grated, divided
  • 1 pinch salt to taste
  • 1 pinch pepper to taste
  • 1 tablespoon fresh parsley or basil, chopped

Instructions 

  • Heat butter in a large skillet over medium-high heat. Add the shrimp and tomatoes, and season with salt and pepper to taste. Cook for 2 minutes, then add the garlic and cook for a further minute until shrimp starts to change colour and garlic is fragrant.
  • Reduce heat to low-medium heat. Add pesto, half & half (or heavy cream) and half of the parmesan cheese. Mix and scrape any bits off of the bottom of the pan.
  • Gently simmer for a further minute or two until shrimp is cooked, the sauce thickens slightly and the cheese has melted through. Sprinkle with parsley or basil and remaining parmesan cheese.
  • Serve immediately over pasta, rice, steamed veg, zucchini noodles or cauliflower rice.

Notes

Half and half is an American product, made from equal parts light cream and milk. Substitute with half light cream and half 2% milk (or full fat if not worried about calories and fat counts). Alternatively, use all light cream or heavy cream.
If serving with pasta: add 2 cups cooked pasta along with 1/4 cup of reserved pasta water into the sauce. Gently mix the sauce through until combined. Add in the shrimp and serve immediately.

    We made this last night and had it with linguine. It was delicious! Easy enough for a weeknight dinner but fancy enough for company. Used some frozen shrimp we already had plus cherry tomatoes from our garden! Will definitely add it to the rotation!

    I made this for dinner tonight and it was WONDERFUL! I was a little concerned since pesto is not anything we have ever eaten before but both my husband and I absolutely loved it. It was very fast and easy with a lovely fresh and creamy sauce. and low carb to boot! We also tried Konjac pasta for the first time and loved it too. I have tried several of your recipes and all have been a success.
