The Best Hawaiian Macaroni Salad

But we call is Mac Salad. This Hawaiian macaroni salad hands down my go to recipe with a creamy tang and impeccable flavor using a few quick tricks to take it up a level!

There’s just something magical about Hawaiian-style mac salad. It’s creamy, tangy, a little sweet, and always the unsung hero next to smoky Kalua pork or crispy chicken Katsu on a classic plate lunch. Have you tried a classic plate lunch before? If you haven’t this is a must have, and if you have ever been to Oahu you will know from my First Timer’s Guide to Oahu that going to Rainbow Cafe is THE place. 

I’ve tested so many variations of this iconic side, and the one that finally hits all the notes? It’s inspired by America’s Test Kitchen’s Hawaiian Macaroni Salad — and it’s every bit as good as what you’ll find on the islands. Even my Oahu born and raised brother in law approved! 

Whether you’re planning a backyard luau or just want a nostalgic taste of the islands, this Hawaiian mac salad recipe is simple, crave-worthy, and a total cookout essential.

Why This Hawaiian Macaroni Salad Works

Authentic Hawaiian mac salad is not your average pasta salad. What makes it stand out?

• Overcooked macaroni – Yep, we intentionally overcook the pasta until it’s soft. This helps it soak up the tangy dressing. 
• Vinegar soak – While the pasta is still warm, I learned from ATK to toss it with apple cider vinegar. This punches up the flavor right from the start and gets flavor throughout the pasta, not just flavor in the dressing.
• Simple mix-ins – Grated carrot, celery, a bit of onion, and a touch of sugar round out the flavor without overcomplicating things.
• Mayo-forward – This is the time to break out the good stuff (ahem, Duke’s is my new go to!). It’s creamy, rich, and the true base of the salad.

Ingredients for Authentic Hawaiian Macaroni Salad

Because the original America’s Test Kitchen version creates SO MUCH, like not an exageration, I have halved my recipe. And it still will feed an army. 

Here’s what you’ll need:

• 1/2 pound elbow macaroni (8oz)
• 1/4 cup apple cider vinegar
• 1 cup mayonnaise (Best Foods Mayo/Hellman’s Mayonnaise, or Duke’s is my preferred.) 
• 1 cup whole milk
• 2 teaspoon brown sugar
• 1/4 tsp Ground Black Pepper
• 1/2 teaspoon Salt
• 2 medium carrots, peeled and shredded
• 1 stalk Celery, finely minced
• 2 Green Onions, thinly sliced
• 1/8 tsp Celery Seed – optional, I add it because I love the flavor.

How to Make Hawaiian Macaroni Salad

The instructions are quite simple, but a few little tricks make this truly memorable. Trust the process! 

1. Boil the macaroni – Cook the pasta until very soft (about 12 minutes), not al dente. Drain well. Pour the drained pasta into a large bowl. Do not rinse the pasta under any hot or cold water. You want the starchy exterior to remain. 
2. Add vinegar – Immediately toss the hot macaroni noodles with apple cider vinegar and let it cool for 10 minutes. Every couple of minutes mix the salad around to it soaks in the cider vinegar evenly, and cools more quickly before dressing the salad. This step helps the pasta absorb flavor and gives it a bit of tang.
3. Make the dressing – In a separate bowl, whisk together mayonnaise, milk, sugar, salt, ground pepper, shredded carrots, minced celery, celery seeds, and thinly sliced green onion. Keep it in the refrigerator until ready to dress your mac salad. 
4. Mix and chill – Once the pasta has cooled, stir in 3/4 the dressing until everything is evenly coated. Season with salt and pepper to taste. Chill for at least 1 hour, or ideally overnight. 
5. Taste and adjust – Just before serving, add in the remaining 1/4 of the reserved salad dress, and give it a stir. This will keep the salad extra creamy! Store in an airtight container.
