This classic Hawaiian Macaroni Salad is the perfect side dish for any island-inspired meal, bringing authentic plate lunch vibes right to your dinner table. The creamy, slightly sweet dressing coats every piece of pasta for a comforting dish that gets better as it sits.
I first made this macaroni salad for a backyard luau party and it was the first dish to disappear. Now it's requested at every summer gathering my family hosts, and I've perfected the balance of sweet and tangy flavors.
Ingredients
- Elbow Macaroni: A full pound creates the perfect base for soaking up all the creamy dressing
- Mayonnaise: Use good quality full fat mayo for authentic Hawaiian flavor
- Milk: Creates the perfect creamy consistency and helps the dressing penetrate the pasta
- Sugar: Adds that signature subtle sweetness that defines Hawaiian mac salad
- Apple Cider Vinegar: Balances the richness with just the right amount of tang
- Salt and Pepper: Simple seasonings that enhance without overwhelming
- Yellow Onion: Finely grated to incorporate throughout without crunchy bits
- Carrot: Adds color, subtle sweetness, and a nutritional boost
Step-by-Step Instructions
- Cook the Pasta:
- Boil the elbow macaroni in heavily salted water until it's just past al dente. Hawaiian mac salad traditionally has very soft pasta that will absorb the dressing well. Drain thoroughly and rinse under cold water to stop the cooking process. Transfer to a large mixing bowl and set aside.
- Create the Dressing:
- In a separate bowl whisk together mayonnaise, milk, sugar, apple cider vinegar, salt, and pepper until completely smooth. The consistency should be pourable but still thick. Gently fold in the grated onion and carrot making sure they're evenly distributed throughout the dressing.
- Combine and Marinate:
- Pour about two thirds of the dressing over the still warm macaroni and fold gently until each piece is coated. Cover and refrigerate for 15 minutes to allow the pasta to absorb the initial dressing. After resting, add the remaining dressing and gently mix again. Refrigerate for at least an hour before serving allowing the flavors to fully develop.

The secret to this recipe is allowing the warm pasta to absorb the first layer of dressing before adding more. My Hawaiian neighbor taught me this technique after I complained about my mac salad always drying out. This method ensures creamy pasta through and through not just on the surface.
The History Behind the Dish
Hawaiian macaroni salad became popular during the plantation era when workers from various cultures would share lunch items. The Japanese workers introduced rice while other groups contributed different proteins. This creamy macaroni salad completed what is now known as the iconic plate lunch found throughout Hawaii. The dish reflects Hawaii's unique multicultural history and has evolved with some regional differences across the islands.
Perfect Pairings
This macaroni salad is traditionally served as part of a plate lunch alongside two scoops of white rice and a protein like Kalua pork, teriyaki chicken, or grilled fish. The creaminess perfectly balances spicy or savory main dishes. For a complete backyard luau, serve with huli huli chicken, pineapple rings, and Hawaiian sweet rolls. The cooling effect of the mac salad makes it especially good with anything barbecued or grilled.
Storage and Make-Ahead Tips
This salad actually improves with time as the flavors meld together. You can make it up to two days in advance keeping it tightly covered in the refrigerator. If the salad seems dry after storing, simply stir in a tablespoon or two of milk to refresh the creaminess. The salad will keep for up to five days refrigerated but is best within the first three days when the texture is optimal.

There's nothing like a creamy, authentic Hawaiian macaroni salad to bring a little taste of the islands to any meal.
