Hawaiian Macaroni Salad Recipe America’s Test Kitchen: Sweet Pea and Carrot Crunch

There’s a reason this creamy macaroni salad appears at every Hawaiian gathering—its perfect balance of textures and flavors makes it irresistible. I’ve refined this version to capture that signature island taste with a few simple but crucial tweaks.

The secret lies in the combination of tender elbow macaroni, crisp sweet peas, and shredded carrots, all folded into a tangy-sweet mayonnaise dressing. A splash of vinegar brightens the richness, while a touch of mustard adds depth without overpowering the dish.

What you’ll get is a salad that’s creamy yet light, with a satisfying crunch in every bite. It’s the kind of side that elevates any meal, from backyard barbecues to holiday spreads.

Serve it chilled for the best texture and flavor. Here’s how to make it perfectly every time.

Ingredients for Hawaiian Macaroni Salad Recipe America’s Test Kitchen

Every Hawaiian gathering needs this creamy, crunchy, perfectly balanced salad.

The macaroni is key—De Cecco or Barilla hold their shape best after cooking. Sweet peas should be bright green (frozen works in a pinch). For the carrots, pre-shredded bags save time but whole carrots shredded fresh taste sweeter. Hellmann’s or Duke’s mayo deliver that signature richness. The onion and celery add the essential crunch, so don’t skip them even if you’re short on time.

No apple cider vinegar? White vinegar at half the amount gets you close. Yellow mustard is classic, but Dijon at half the quantity adds a nice depth. For a lighter version, Greek yogurt at half and half with mayo works surprisingly well. The sugar can be swapped for honey (1:1), but it’ll add a slightly floral note. Fresh herbs like dill or parsley would be a great addition if you’ve got them.

This salad tastes even better after 24 hours in the fridge—perfect for making ahead. Keeps well for 4-5 days in an airtight container. The veggies will soften slightly over time, but the flavor just keeps getting better. Ideal for picnics since it holds up well at room temperature.

Step-by-Step Instructions for Hawaiian Macaroni Salad

This method ensures creamy, well-balanced flavors with the perfect crunch in every bite.

Step 1: Cook and Cool the Elbow Macaroni

Bring a pot of salted water to a rolling boil and add the 8 oz Elbow Macaroni. Cook until al dente, about 1 minute less than package directions specify. You want it slightly underdone so it absorbs the dressing without turning mushy.

Drain the macaroni immediately and rinse under cold water to stop the cooking process. Shake off as much water as possible, then spread it on a baking sheet to cool completely. This prevents the pasta from turning the salad gummy and ensures it stays firm when mixed with the dressing.

Step 2: Prepare the Fresh Vegetables

While the macaroni cools, finely dice the 0.25 cup Sweet Onion and 0.5 cup Celery. Peel and shred the 2 whole Carrots using a box grater or food processor. If using frozen 1 cup Sweet Peas, thaw them under cold water and pat dry with a paper towel.

The finer the dice, the better these ingredients will distribute throughout the salad. I prefer a uniform ¼-inch dice for the onion and celery to ensure every forkful has the right texture balance. The shredded carrots should be light and fluffy, not packed down.

Step 3: Whisk Together the Creamy Dressing

In a large bowl, combine the 1.5 cups Mayonnaise, 2 tbsp Apple Cider Vinegar, 1 tbsp Yellow Mustard, 1 tbsp Granulated Sugar, 0.5 tsp Salt, and 0.25 tsp Black Pepper. Whisk until smooth and fully emulsified.

Slowly pour in the 0.25 cup Whole Milk while whisking constantly to create a silky, pourable dressing. The milk thins it just enough to coat the pasta and vegetables without being heavy. Taste and adjust the seasoning—you might want a pinch more salt depending on your mayonnaise brand.

Step 4: Combine and Chill for Maximum Flavor

Add the cooled Elbow Macaroni, Sweet Peas, shredded Carrots, Sweet Onion, and Celery to the bowl with the dressing. Fold everything together gently but thoroughly with a silicone spatula, ensuring every piece is well coated.

Cover the bowl tightly with plastic wrap and refrigerate for at least 2 hours, or ideally overnight. This chilling time allows the pasta to absorb the dressing and the flavors to meld. The salad will thicken slightly as it sits, so don’t worry if it seems a bit loose at first.

Give it one final stir before serving to redistribute the dressing. The texture should be creamy but not soupy, with a bright, tangy flavor and a satisfying crunch from the fresh vegetables.

Make-Ahead Tips for This Recipe

Overnight Chilling

For the best flavor, make this salad the day before serving. The pasta absorbs the dressing overnight, creating that signature creamy texture Hawaiian macaroni salad is known for. I always prep it 24 hours ahead for gatherings. 💡

Same-Day Prep

If you’re short on time, you can make it the morning of. Just ensure it chills for at least 4 hours in the fridge. The flavors won’t be as developed, but it’ll still taste great. I’ve done this for last-minute potlucks with success.

Vegetable Prep

Prep all your vegetables the night before to save time. Store them in separate airtight containers in the fridge. The onion, celery, and carrots will stay crisp for up to 2 days when stored this way.

Dressing Adjustments

If making ahead, you might need to add 1-2 tbsp milk before serving if the salad seems thick. The pasta continues to absorb liquid as it sits. I always keep a little extra milk on hand for this.

Storage Containers

Use a large, shallow container rather than a deep bowl for chilling. This allows the salad to cool more evenly in the fridge. I recommend glass containers with tight-fitting lids for easy storage and transport. ❄️

Final Touches

Always give the salad a good stir before serving to redistribute the dressing. I like to taste and adjust seasoning one last time, adding a pinch of salt or splash of vinegar if needed.
