Creamy Pesto Shrimp Alfredo is the kind of dinner that feels fancy but takes barely any time at all. Juicy shrimp simmer in a rich, garlicky pesto alfredo sauce, finished with parmesan and sweet blistered tomatoes for a pop of color and flavor.
The best part? It’s ready in under 10 minutes and fits right into gluten-free or low-carb meals. Spoon it over zucchini noodles or cauliflower rice, or twirl it up with your favorite pasta if carbs are on the menu. Either way, that creamy pesto sauce steals the show.
What Makes This Creamy Shrimp Alfredo Work
This Creamy Shrimp Alfredo comes together in no time, but still tastes like something you’d order at a restaurant. That creamy alfredo base is infused with basil pesto, giving it a bold, herby richness that pairs perfectly with tender, juicy shrimp. A splash of cream brings everything together into a silky sauce that clings beautifully in every bite.
Blistered cherry tomatoes add a fresh, sweet contrast to the rich sauce,while parmesan deepens the savory flavor. Whether your’e going low-carb or twirling it with pasta, it’s a quick weeknight recipe that feels like a treat.
What Goes Into Creamy Shrimp 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 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.
How To Make Creamy Pesto Shrimp Alfredo
- Sauté Shrimp and Tomatoes Heat the butter in a large skillet over medium-high heat. Add the shrimp and grape tomatoes, seasoning with salt and pepper. Cook for about 2 minutes until the shrimp begins to turn pink.
- 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.
- Pour in the Sauce Ingredients Reduce the heat to low-medium. Add the basil pesto, half anf half (or heavy cream), and half of the parmesan cheese. Stir gently to combine.
- Simmer the Sauce Let the sauce gently simmer for 1-2 minutes until it thickens slightly and the cheese melts into the mixture.
- Finish with Fresh Herbs Sprinkle in the chopped parsley or basil alng with the remaining parmesan. Stir once more to blend the flavors together.
- 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 bread 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.
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.

Third time making this today! By far one of my favorite recipes. Easy and taste amazing. Thanks for sharing another great recipe
Yum! Yum!
We don’t do cups here, UK, but I just made sure I made plenty sauce and we mopped it up with garlic bread. Avocado salad on the side.
Made this tonight, super easy, quick and delicious. Used frozen cooked shrimp, made the homemade pesto, and served over riced cauliflower. It was a huge hit. Will make again in a heartbeat:)
This was so easy. And tasty. Skipped the tomatoes and served over riced cauliflower for an easy, low carb, keto meal. Making it with chicken next!! Yum!!
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!
Can you use frozen cooked shrimp?
Yes, that works great!
This was SO good. We really enjoyed it. It was so easy and fast too. This is going into the regular rotation!
YAY! That is perfect and just what I love to hear! Thank you for sharing! XO
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.
Thank you for another restaurant quality recipe. I made this for dinner last night and my husband said it is his new favorite meal. He is now requesting it for his birthday dinner.
YAY!! That is a bonus when the husband loves it! So glad that it turned out well for you! Thanks so much for sharing!
