Hawaiian macaroni salad (my most popular recipe and for good reason)

If there is one recipe on this entire site that people come back to again and again, it is this one. Hawaiian macaroni salad has been my most requested dish since the moment I first posted it, and honestly, I am not even surprised.

There is something about Hawaiian mac salad that hits differently from every other pasta salad out there. It is not loaded with a dozen vegetables or dressed in a sharp vinaigrette.

It is simple, creamy, soft, and deeply comforting in a way that feels almost nostalgic even if you have never been to Hawaii. The magic is in the dressing and in knowing exactly how to cook the pasta to get that signature texture.

I have made this recipe more times than I can count — for cookouts, for family dinners, for meal prep, and sometimes just because I wanted something good in the fridge. Every single time it disappears fast. This is that recipe. Let's get into it.

Why you'll love this recipe

• It is incredibly simple to make. No complicated techniques, no hard-to-find ingredients. Boil pasta, make dressing, mix everything together, and chill. That is genuinely it.
• The dressing is rich and perfectly creamy. This is not a light, watery dressing situation. It is thick, luscious, and coats every single piece of macaroni in the most satisfying way.
• The pasta texture is everything. Hawaiian mac salad uses slightly overcooked pasta on purpose. It soaks up the dressing better and gives you that signature soft, creamy bite that makes this dish so distinct.
• It is a guaranteed crowd pleaser. Kids love it, adults love it, picky eaters love it. This is one of those rare recipes that genuinely works for everyone at the table.
• It gets better as it sits. Make it the night before and you will be amazed at how much the flavor deepens. The pasta absorbs the dressing overnight and becomes even more creamy and delicious.
• It goes with absolutely everything. Grilled chicken, pulled pork, burgers, ribs — Hawaiian mac salad is the perfect side dish for practically any meal you can think of.

Ingredients with key notes

For the macaroni salad:

• 16 oz elbow macaroni — This is the pasta you want for Hawaiian mac salad. The small curved tubes hold the creamy dressing perfectly. Do not substitute with a different pasta shape — it changes the whole texture and feel of the dish.
• 1 cup shredded carrots — Adds a subtle sweetness and a small pop of color throughout the salad. You can buy pre-shredded carrots to save time or shred them yourself for a fresher texture.
• 1/4 cup green onions, thinly sliced — Adds a mild onion flavor without being too sharp or overpowering. This is optional but recommended for a little extra flavor dimension.

For the creamy dressing:

• 2 cups mayonnaise — Full fat mayo is non-negotiable here. This is the foundation of the entire dressing and the reason the salad is so rich and creamy. Do not use light mayo or miracle whip — the flavor and texture will not be the same.
• 1/4 cup whole milk — This is the secret ingredient that makes Hawaiian mac salad different. Adding milk to the warm pasta thins the dressing slightly and helps it soak deep into every noodle. Use whole milk for the best result.
• 3 tablespoons apple cider vinegar — Adds a gentle tang that balances the richness of the mayo perfectly. Do not skip this — it is what keeps the dressing from feeling too heavy.
• 1 tablespoon sugar — Just a small amount adds a subtle sweetness that is very characteristic of authentic Hawaiian mac salad. You can reduce it slightly if you prefer but do not leave it out entirely.
• 1 teaspoon garlic powder — Adds a quiet savory depth to the dressing without overpowering anything else.
• Salt and white pepper to taste — White pepper is preferred here over black pepper. It blends into the dressing more smoothly and gives a gentler heat. You can see the black specks in the photos — that works too if white pepper is all you have.

Step-by-step instructions

Step 1: Cook the pasta

Bring a large pot of well-salted water to a boil. Add the elbow macaroni and cook it for two to three minutes longer than the package directions suggest. Yes, intentionally. Hawaiian mac salad uses slightly overcooked pasta that is soft enough to soak up the dressing properly. This is what gives it that signature creamy texture. Drain the pasta but do not rinse it — you want to keep some of the starch on the surface.

Step 2: Add milk while the pasta is hot

This step is important. While the pasta is still hot and fresh from draining, transfer it to a large mixing bowl and immediately pour the whole milk over it. Toss the pasta gently so the milk coats every piece. The hot pasta will absorb the milk as it cools, which is exactly what you want. Let it sit for about five minutes.

Step 3: Make the dressing

In a separate bowl, whisk together the mayonnaise, apple cider vinegar, sugar, garlic powder, salt, and white pepper until smooth and well combined. Taste it before adding it to the pasta. It should be creamy, slightly tangy, and just a touch sweet. Adjust the seasoning as needed.

Step 4: Combine everything

Add the shredded carrots and green onions to the pasta bowl. Pour about two thirds of the dressing over everything and toss well until fully coated. Reserve the remaining dressing for later — the pasta will absorb a lot of it as it chills.

Step 5: Chill and finish

Cover the bowl tightly with plastic wrap and refrigerate for at least one hour. Two hours is better. Overnight is best. When you are ready to serve, add the reserved dressing and toss again. The salad will have thickened up nicely as it chilled. Taste for seasoning and add a little extra salt, pepper, or vinegar if needed before serving.

Serving suggestions

• Serve it as the classic side dish alongside kalua pulled pork, grilled teriyaki chicken, or Hawaiian BBQ ribs for a full plate lunch experience right at home.
• Pair it with grilled burgers and coleslaw at your next backyard cookout for a crowd-pleasing summer spread.
• Serve it in small individual cups or bowls as part of a potluck spread — it is easy to portion and travels extremely well.
• Add a light sprinkle of white pepper and a few extra green onion slices on top right before serving for a clean and polished presentation.
• Pair it with a simple green salad and some garlic bread for a satisfying and easy weeknight dinner that comes together fast.

Storage tips

Refrigerator: Store leftover Hawaiian macaroni salad in an airtight container in the fridge for up to 4 days. It genuinely gets better by day two as the pasta continues to absorb the dressing and the flavors deepen.

Before serving leftovers: The pasta absorbs the dressing as it sits and the salad will look thicker and drier the next day. Stir in a spoonful or two of mayonnaise and a small splash of whole milk before serving to bring the creaminess back. Taste and adjust seasoning.

Freezer: This recipe does not freeze well at all. The mayo-based dressing separates completely when frozen and thawed, and the pasta texture becomes unpleasant. Keep it refrigerated and enjoy within 4 days.

Meal prep tip: This recipe is perfect for meal prep. Make a full batch on Sunday and enjoy it as a side dish throughout the week. Just keep the reserved dressing separate and stir it in as needed to keep the salad fresh and creamy.

Closing

And there you have it — the Hawaiian macaroni salad recipe that started it all for me. Simple ingredients, a few key techniques, and one seriously creamy, comforting bowl of goodness that never gets old.

Whether you are making it for a summer cookout, a family dinner, or just because you need something reliable and delicious in your fridge this week, this recipe will not let you down. It never does.

Make it, taste it, and then try not to eat the whole bowl before it even makes it to the table. That last part is harder than it sounds :)
