This easy Hawaiian macaroni salad combines tender elbow macaroni, grated carrots, sweet onion, and green onions in a rich, tangy mayonnaise dressing. Creamy, cool, and simple to prepare, it’s the perfect side dish for a Hawaiian plate lunch, summer cookout, potluck, or family dinner.

Hawaiian macaroni salad is everything you want in an easy side dish. It’s cool and creamy, has just enough tang to balance the mayonnaise, and is made with simple ingredients you can find at nearly any grocery store.

Unlike many mainland classic macaroni salad, this version doesn’t rely on pickles, mustard, chopped eggs, cheese, or lots of crunchy vegetables. The ingredient list stays intentionally simple. Grated carrot adds a little sweetness and color, while grated sweet onion and sliced green onion create a savory flavor that runs through the entire bowl.

The dressing is what makes this Hawaiian mac salad stand out. Mayonnaise gives it its signature richness, whole milk loosens the dressing so it coats the pasta evenly, and rice vinegar adds a mild tang without overpowering the other ingredients. After chilling, the pasta and vegetables come together in a creamy, comforting salad that goes with nearly any grilled or roasted main dish.

This is also an excellent recipe to prepare ahead of time. In fact, it tastes better after it has rested in the refrigerator for at least an hour. That makes it especially useful when you’re planning a barbecue, birthday party, picnic, or busy weeknight dinner.

What Is Hawaiian Macaroni Salad?

Hawaiian macaroni salad is a creamy, mayonnaise-based pasta salad commonly served as part of a local-style plate lunch. A typical plate lunch pairs a savory meat with white rice and a scoop of cool mac salad. The mild, creamy pasta helps balance rich, salty, sweet, or smoky main dishes.

Recipes vary from cook to cook, but most versions begin with elbow macaroni, mayonnaise, and grated carrot. Onion, milk, vinegar, sugar, celery, green onion, and seasonings may also be included depending on the family or restaurant.

What makes Hawaiian-style mac salad different from a classic mainland macaroni salad is its simplicity. It generally contains fewer mix-ins and has a smoother, richer dressing. You usually won’t find large pieces of bell pepper, cheese, pickles, or fresh herbs competing with the creamy pasta.

There also isn’t any pineapple in this recipe. Despite the common habit of adding pineapple to dishes labeled “Hawaiian,” pineapple isn’t a standard ingredient in traditional local-style macaroni salad. This dish is meant to be mild, savory, creamy, and tangy rather than fruity.

Hawaiian plate lunch developed through the blending of food traditions brought together in Hawaiʻi, and macaroni salad became one of its best-known side dishes. Today, it is served at restaurants, drive-ins, food trucks, cookouts, family gatherings, and casual celebrations.

Ingredients You’ll Need

The complete measurements are included in the recipe card, but here is a closer look at what each ingredient does in this Hawaiian macaroni salad recipe.

• Elbow macaroni: Elbow macaroni is the classic pasta shape for this salad. Its curved shape and hollow center catch the creamy dressing, helping every bite taste rich and flavorful.
• Mayonnaise: Mayonnaise creates the thick, creamy base of the dressing. Use a full-fat mayonnaise for the closest texture and flavor; light mayonnaise can make the finished salad thinner or slightly sweeter.
• Whole milk: Milk loosens the mayonnaise and helps it flow around the pasta. Whole milk gives the dressing a smooth texture without making it watery.
• Rice vinegar: Rice vinegar adds gentle acidity that cuts through the richness of the mayonnaise. It has a softer flavor than distilled white vinegar, making it a good choice for a mild, balanced salad.
• Kosher salt: Salt seasons the dressing and brings out the sweetness of the carrots and onion. Remember that the pasta water is also salted, so taste the salad after chilling before adding more.
• Green onions: Use only the green portions for a fresh onion flavor and pop of color. Slice them finely so they mix evenly throughout the salad.
• Carrot: Finely grated carrot adds color, mild sweetness, and a little texture. Grating it finely helps it blend into the salad rather than creating large, crunchy pieces.
• Sweet onion: Grated sweet onion distributes savory onion flavor throughout the dressing. Grating is important because it releases the onion’s juices and prevents noticeable chunks from overpowering the creamy pasta.

The Best Mayonnaise for Hawaiian Mac Salad

Because mayonnaise is the main ingredient in the dressing, its flavor makes a noticeable difference. Choose a thick, full-fat mayonnaise with a balanced flavor rather than a strongly seasoned specialty mayonnaise.

Best Foods is a common choice in Hawaiʻi, while the same brand is sold as Hellmann’s in many other parts of the United States. Duke’s or another high-quality full-fat mayonnaise can also work. The most important thing is to use a mayonnaise you already enjoy.

Avoid using Miracle Whip unless you specifically want a sweeter and sharper salad. Its flavor is different from traditional mayonnaise and will noticeably change the finished dish.

Japanese-style mayonnaise is also richer and more seasoned than standard American mayonnaise. It can be delicious, but it won’t create the same mild flavor as the recipe written here.

Should You Rinse the Macaroni?

Rinsing pasta is usually discouraged for hot pasta dishes because the starch helps sauces cling to the noodles. Cold pasta salads are different.

Rinsing the macaroni under cold water stops the cooking process, cools the noodles quickly, and washes away some of the excess surface starch. This helps keep the elbows from sticking together while they drain.

For this recipe, rinsing is especially helpful because the dressing contains a generous amount of mayonnaise. Starting with cool, well-drained pasta helps prevent the mayonnaise from becoming oily and keeps the final salad thick and creamy.

The key is to let the macaroni drain thoroughly after rinsing. Shake the colander several times, then leave it over the sink for a few minutes. Water trapped inside or around the noodles can dilute the dressing.

Some Hawaiian mac salad recipes call for adding vinegar to warm pasta so the noodles absorb it. That is a valid alternative technique, but this recipe mixes rice vinegar directly into the creamy dressing after the pasta has cooled. Follow the written method for consistent results with the ingredient ratios provided.

How Soft Should the Macaroni Be?

Traditional Hawaiian mac salad is often made with pasta that is softer than the firm al dente texture used for hot Italian pasta dishes. Softer noodles absorb flavor easily and give the salad its comforting texture.

For the best result, avoid undercooking the pasta. Very firm noodles can feel hard once refrigerated and may not blend well with the creamy dressing. You should also avoid cooking the macaroni until it begins to fall apart.

Aim for noodles that are tender all the way through but still hold their curved shape. Test one piece before draining. It should be easy to bite without a hard center.

Why Did My Macaroni Salad Turn Out Dry?

Macaroni absorbs moisture as it sits, especially after several hours in the refrigerator. That means a salad that looked perfectly creamy when first mixed may appear thicker the next day.

This doesn’t mean the recipe failed. In most cases, the salad only needs a small amount of fresh dressing to bring back its creamy consistency.

Mix 2 tablespoons of mayonnaise with 1 or 2 teaspoons of whole milk. Fold this mixture into the cold salad, adding more only as needed. The milk makes the mayonnaise easier to distribute without creating heavy clumps.

Dry salad can also result from undercooked pasta. Very firm noodles don’t have the same soft, tender texture and can make the entire dish seem less creamy. Cooking the pasta until tender and allowing the completed salad to rest gives the dressing time to coat every noodle.

Be careful not to fix a dry salad by adding milk alone. Too much milk may make the dressing watery. Combining a small splash of milk with mayonnaise preserves the rich texture.

Variations and Customizations

This simple recipe is delicious as written, but you can make small adjustments to suit your family or the ingredients you have available.

• Add peas: Fold in thawed frozen peas for extra color and a mild sweetness. Make sure they are fully thawed and drained first.
• Add celery: Mix in finely chopped celery if you like a little crunch. Use a small amount so the celery doesn’t overpower the smooth, creamy texture.
• Make it sweeter: Add a small amount of granulated sugar to the dressing if you prefer a sweeter restaurant-style macaroni salad.
• Make it vegan: Use vegan mayonnaise and unsweetened plant-based milk. Choose a neutral milk without vanilla or added sugar.
• Change the vinegar: Substitute apple cider vinegar for the rice vinegar if you want a slightly stronger, fruitier tang.

For a version that remains closest to a classic Hawaiian side dish, keep the mix-ins simple. Adding large amounts of meat, cheese, pickles, or bold seasonings can turn it into a tasty pasta salad, but it will no longer have the same mild plate-lunch character.

What to Serve With Hawaiian Macaroni Salad

Hawaiian macaroni salad is traditionally served cold next to a savory main dish and steamed white rice. Its creamy, mild flavor works especially well with meats coated in sweet, smoky, salty, or tangy sauces.

Try serving it with:

• Kalua-style pulled pork
• Huli huli chicken
• Teriyaki chicken or beef
• Chicken katsu
• Grilled chicken thighs
• Sticky barbecue ribs
• Slow-cooker pulled pork
• Grilled hamburgers
• Hot dogs
• Cirtus Marinated Grilled Shrimp
• Grilled fish
• Shredded barbecue chicken

To build a simple Hawaiian plate lunch at home, add one scoop of macaroni salad, one or two scoops of steamed white rice, and your favorite grilled or slow-cooked protein. Spoon extra sauce from the meat over the rice, but keep the macaroni salad cool and separate until serving.

It also makes an easy potluck side dish for summer parties. Serve it alongside baked beans, coleslaw, potato salad, corn on the cob, fruit salad, or a tray of fresh pineapple.

For a casual family dinner, pair this cold pasta salad with grilled chicken and sliced cucumbers. The salad is rich enough to make a simple meal feel complete without requiring another complicated side.

Make-Ahead Instructions

Hawaiian macaroni salad is a great make-ahead recipe because it needs time to chill. You can prepare it in the morning for dinner that evening or make it the night before a party.

After mixing the salad, place it in an airtight container and refrigerate it. Before serving, stir it well and check the consistency. The pasta will continue to absorb some of the dressing as it rests.

If the salad looks dry, combine a little additional mayonnaise with a splash of milk, then gently fold it into the pasta. Add only enough to restore the creamy texture.

You can also prepare some components separately. Cook, rinse, and drain the macaroni, grate the carrots and onion, and slice the green onions. Refrigerate everything in separate airtight containers, then mix the salad several hours before serving.

For the best flavor and texture, prepare the fully assembled salad no more than one day before you plan to serve it. It will remain safe and enjoyable beyond that point when stored correctly, but the texture is usually creamiest during the first day or two.

Storage

Store leftover Hawaiian macaroni salad in an airtight container in the refrigerator. Keep it refrigerated until you are ready to serve it, especially during warm weather.

For the best quality, eat it within 3 to 4 days. Stir the salad before serving because some of the dressing may settle or be absorbed by the noodles.

Don’t leave mayonnaise-based pasta salad at room temperature for extended periods. At a picnic, barbecue, or potluck, place the serving bowl over a larger bowl filled with ice and return leftovers to the refrigerator promptly.

Freezing isn’t recommended. Mayonnaise-based dressings can separate after freezing and thawing, while the macaroni and vegetables may develop a soft or watery texture.
