This classic Hawaiian Macaroni Salad recipe is an iconic side dish across all the Hawaiian Islands, served on lunch plates and food trucks. It’s a bit tangy and sweet and very creamy, perfect for backyard summer cookouts or anytime throughout the year.See below the recipe card for step-by-step images.
In a large pot of salted boiling water, cook the macaroni according to package directions, except tack on an additional 3 minutes until it's fat and soft. Drain and then dump it back into the pot, off the heat. Pour the apple cider vinegar evenly over the top and gently stir until the pasta absorbs the vinegar. Stir in the carrots and onion. Cover and let it cool for 10 minutes.
While the pasta is cooling, make the dressing. Whisk together all the dressing ingredients in a medium bowl until smooth.
Remove the lid from the pasta pot and pour in HALF of the dressing.
Gently toss to coat, then place the lid back on and let stand for 20 minutes, stirring every 5 minutes or so, so the pasta can absorb the dressing.
Transfer mixture to a large mixing bowl, then pour the remaining dressing over the top along with the scallions and stir to combine.
Let it cool for another 20 minutes at room temperature.
Cover and refrigerate for at least 1 hour (ideally at least 4 hours).
Gently stir before serving, adding in 1 to 2 tbsp milk, if needed, to thin it out a bit.
Garnish with small diced scallions and enjoy cold.
