A Note from Kim

Your New Summer Sidekick

Pasta salads, like this shrimp pasta salad, have made a serious comeback, and not the heavy, mayo-filled kind you might remember. Don’t get me wrong, those nostalgic recipes have their charm, but this fresh, mayonnaise free version is on a whole new level!

Loaded with tender pasta, juicy shrimp, crisp summer veggies, and a zesty Italian ranch dressing, this dish is bright, hearty, and full of flavor. Whether it’s a summer BBQ, picnic, or potluck, this one is guaranteed to impress with its color, texture, and freshness.

With love (and lots of good eats), - Kim

Really good! Very flexible in what you put in it. You can make a lot or a little depending on your needs, and interest in vegetables.

Ingredients needed

This easy shrimp pasta salad recipe is filled with flavor, colors and textures that make it absolutely irresistible. Here’s everything you’ll need to make it for your next cookout or party:

Shrimp, cucumber, onions, corn, bell pepper, garlic and uncooked pasta divided into small bowls.
  • Pasta. Feel free to use any variety you’d like! I love tri-color rotini for extra color, but cavatappi or bowtie noodles work great too.
  • Fruits & veggies. We’re adding colorful bell peppers (I like using orange, yellow and red bell pepper), sweet corn, cucumber, juicy cherry tomatoes, corn, and avocado.
  • Shrimp. Precooked small shrimp (usually sold frozen) makes this recipe quick and easy. I like using small salad shrimp to match the size of the noodles and veggies. If you can only find larger shrimp, simply chop them into bite-sized pieces before adding to the salad (and make sure you cook them first, of course!). See the note in the recipe card for more details on how to cook shrimp for this recipe.
  • For the dressing. I like to keep it simple by just mixing store-bought ranch dressing and Italian dressing with some pesto, garlic, red onion and garlic powder. Super easy, yet really tasty!

Recipe variations

This recipe is pretty spectacular as written, but the great thing about pasta salad is that you can easily customize the ingredients. Here’s some ideas:

  • Pasta. I love using rotini noodles because they are fun to eat and the sauce gets trapped in the corkscrews, allowing for each bite to be SO flavorful! However, feel free to use any type of short pasta such as penne, farfalle, fusilli, shells or elbow macaroni.
  • Make it gluten free. Simply use your favorite gluten-free pasta shape.
  • Protein. You can easily change up the protein by swapping the shrimp for grilled chicken, salami or cooked crumbled bacon. You could even make this vegetarian by simply omitting the shrimp or swapping with canned chickpeas.
  • Cheese. Try adding in some cheese. Cubed cheddar cheese works great, but even mozzarella or crumbled feta cheese would be delicious.
  • Vegetables. Add more veggies to the mix with cooked green beans, marinated artichoke hearts, celery, peas, olives, fresh spinach or grilled zucchini.

Kim’s recipe tips

  • Salt the pasta water. Since this is eaten cold, the flavors can get muted. Make sure the pasta is well-salted as it cooks, since salting is the only chance you have to season the actual noodles. Read about how to properly salt your pasta water here. As a general rule of thumb, add 1 teaspoon salt to 4 cups of water. Also, don’t be afraid to add more salt to the finished salad, if it needs it.
  • Cook the pasta to al dente. Because the pasta sits in dressing, it tends to get soggy if overcooked. Pasta also gets a little firmer when served cold, so don’t undercook it or it can end up a bit crunchy. Boil the pasta according to the package directions of what al dente is (for rotini, that is 7-8 minutes).
  • Chill before serving. Letting it rest in the fridge gives the flavors time to meld together.
  • Add avocado last. Fold it in right before serving so it stays fresh and doesn’t brown.

Frequently asked questions

What are the five mistakes to avoid pasta salad?

-Not using the right size and shape of pasta. Short pasta works best. 
Overcooking or undercooking the pasta. Cook pasta just until al dente.
-Not seasoning the pasta enough. Salt the pasta water and once everything is mixed, taste and add salt and pepper as needed.
-Not dressing the pasta salad while it’s still warm. You will want to cool the pasta slightly, but don’t wait too long before tossing it in the dressing. This helps the dressing stick to the pasta.
-Making your pasta salad too far in advance. This great to make ahead a few hours or a day, but after more than a day, it will start to lose some freshness.

Does pasta salad get softer?

Yes, as the pasta soaks up the dressing, it will soften up a bit further, which is why you want to cook it to just al dente.

How to cook shrimp for pasta salad?

Boil a pot of water, and fill a medium-sized bowl with cold water and ice cubes. Once the water is boiling, add the shrimp and cook for 2-3 minutes. Drain the shrimp and add them to the ice bath to stop them from cooking further. Let them cool in there for a few minutes prior to draining them and patting them dry with a paper towel. 

Serving options

Shrimp pasta salad is the ultimate simple meal or side dish! My whole family loves this one, and you just can’t go wrong with the combination of succulent shrimp, crunchy veggies, tender pasta and zesty dressing. Here’s some ways to serve it:

  • Straight from the bowl. The noodles, high-protein shrimp and all of the vegetables make this salad plenty filling for a light meal.
  • Atop fresh greens. If you want to add even more nutrition and veggie goodness, you could toss this pasta recipe with fresh greens, then add on a bit of extra dressing to create a satisfying green salad.
  • As a side dish. I typically serve this as a side with grilled meats, burgers or sandwiches. You could even omit the shrimp, if preferred.

Make ahead & storage recommendations

  • Make ahead. This is great to make several hours in advance of serving because it’s best when served chilled. You can even mix the dressing together up to 2 days ahead of time, and store it in the refrigerator.
  • Storing leftovers. Place leftover salad in an airtight container in the fridge for about 3 days. Before serving again, give it a good stir, taste and season again as needed. I would recommend adding the avocado on when you’re ready to serve so that it stays fresh.
