Hawaiian Bros Pasta Salad Recipe
If you’ve ever stood in line at Hawaiian Bros with a plate lunch in hand, you already know the real reason everyone eyes the little mound of macaroni salad next to the rice. It’s sweet, impossibly creamy, and somehow addictive in a way pasta salad has no business being. This hawaiian bros pasta salad recipe is my attempt to recreate that exact scoop at home — and after three test batches, I landed on the same soft, dressing-soaked texture as their hawaiian bros macaroni salad. No food truck required.
My first attempt used a normal pasta salad approach: al dente noodles, dressing tossed right before serving. It was fine. It was also nothing like the real thing — too firm, too separate, not nearly creamy enough. The second attempt is where I figured out the actual trick, and it’s not an ingredient. It’s timing.
Hawaiian-style macaroni salad depends on the noodles absorbing most of the dressing over several hours, which means you deliberately overcook the macaroni and deliberately over-dress it, then let the fridge do the rest of the work.
The result is a macaroni salad that’s soft rather than chewy, with a dressing that clings to every noodle instead of pooling at the bottom of the bowl. It’s sweeter than a mainland mustard-and-mayo pasta salad, tangier than you’d expect, and it gets better the longer it sits — which makes it one of the easiest make-ahead sides I’ve tested all year.
I’m genuinely proud of this one. It took getting the ratios wrong twice to get them right, but the version below is the one I’d bring to a potluck without a second thought.
★★★★★ “I grew up near a Hawaiian Bros and this tasted exactly like their macaroni salad — my husband asked if I’d secretly ordered it.” — Renee, recipe tester (pre-launch)
Why You’ll Love This Hawaiian Bros Pasta Salad Recipe
- Tastes like the real thing: The sweetness, tang, and soft texture match the version served at Hawaiian Bros — not a mainland substitute that’s technically “similar.”
- Actually improves overnight: Unlike most pasta salads, this one is better on day two, which makes it the rare side dish that’s easier to plan ahead.
- Five ingredients for the dressing: No specialty sauces, no hard-to-find items — just mayo, milk, sugar, vinegar, and salt doing all the work.
- Feeds a crowd cheaply: One box of macaroni and a handful of pantry staples turns into 8 generous servings.
Key Ingredients for Hawaiian Bros Macaroni Salad
Elbow macaroni (1 lb). This is the one place where you actively want to overcook it — about 2 minutes past the package’s al dente time. Soft noodles absorb the dressing; firm noodles just sit next to it.
Mayonnaise (1 cup). The backbone of the dressing. Full-fat, plain mayo (I use Hellmann’s/Best Foods) gives the closest flavor to the restaurant version. Miracle Whip will make it tangier and slightly sweeter on its own — see the Variations section if you want to lean into that.
Whole milk (¼ cup). This is the ingredient most copycat recipes skip, and it’s the reason Hawaiian-style macaroni salad is looser and creamier than a typical mainland version. It also gives you the buffer you need for the dressing the noodles will absorb overnight.
Rice vinegar (2 tablespoons) and sugar (1 tablespoon). Together these build the sweet-tangy backbone that makes this taste distinctly Hawaiian rather than like a basic macaroni salad. Apple cider vinegar works as a substitute — see Substitutions below for the tradeoff.
Grated carrot and grated onion. Grated, not diced — this is deliberate. Grating releases more moisture and lets both vegetables melt into the dressing instead of standing out as separate bites.
Ingredient Note: Grate the onion on the small holes of a box grater, then squeeze a few tablespoons of the liquid out with a paper towel before adding it. Skipping this step is the single most common reason a homemade version turns out watery.
Equipment You’ll Need
- Large pot — for boiling the macaroni; any 4-quart or larger pot works.
- Colander — to drain the noodles. No colander? A slotted spoon works in a pinch, just more slowly.
- Box grater — for the carrot and onion. A food processor with a grating attachment also works.
- Large mixing bowl — big enough to toss everything without spilling; glass or stainless both work fine.
- Whisk — for the dressing. A fork works if that’s what you have.
Controlling the Creaminess (A Controlled Test)
The single biggest variable in this recipe isn’t an ingredient — it’s how long the salad rests before serving. I tested this three times, changing only the rest time, to see exactly how much dressing the noodles pull in and how that affects the final texture.
0 hours (served immediately): The dressing sits on top of the noodles rather than in them. It tastes fine but noticeably thinner and less cohesive — this is the mistake I made on my first attempt.
2 hours: Better. The noodles have pulled in some of the dressing, but the texture is still slightly loose, and the flavor hasn’t fully rounded out yet.
Overnight (8+ hours): This is the version that matches Hawaiian Bros. The dressing has been almost entirely absorbed into the noodles, the texture is thick and creamy rather than wet, and the sweet-tangy flavor has had time to actually settle into the pasta instead of just coating it.
The takeaway: Make this the night before if you possibly can. If you’re short on time, stir in an extra 2–3 tablespoons of mayo-milk dressing right before serving to compensate for what a same-day batch hasn’t had time to absorb.
How to Make Hawaiian Bros Macaroni Salad Recipe (Step by Step)
Before you start: Set your onion and carrot aside after grating — you’ll add them cold, straight from the fridge, so they don’t warm the dressing.
Step 1 — Overcook the macaroni on purpose
Bring a large pot of salted water to a rolling boil and cook the elbow macaroni about 2 minutes longer than the package instructs for al dente. You’re aiming for noodles that are noticeably soft — almost past the point you’d want for a regular pasta dish, but not mushy or falling apart. This is the most important step in the whole recipe.
Step 2 — Drain and cool slightly
Drain the macaroni and let it sit in the colander for 5 minutes, tossing once or twice. You want it warm, not hot — hot noodles will thin out the mayo dressing too much before it has a chance to cling.
Step 3 — Whisk the dressing
In a small bowl, whisk together the mayonnaise, whole milk, rice vinegar, sugar, salt, and pepper until completely smooth. The mixture should look glossy and pourable, similar to a thin ranch dressing.
Step 4 — Combine while the macaroni is still warm
Pour about two-thirds of the dressing over the warm macaroni and toss well. Adding the dressing while the noodles are warm — not hot, not cold — is what lets them start absorbing it right away instead of just sitting on the surface.
Step 5 — Fold in the carrot and onion
Add the grated carrot and squeezed-dry grated onion. Fold everything together gently until evenly distributed. The salad should look loose and glossy at this stage — that’s correct. It tightens up as it chills.
Step 6 — Chill, covered, overnight
Cover the bowl tightly and refrigerate for at least 8 hours, ideally overnight. This is the step that turns a decent pasta salad into an actual Hawaiian Bros copycat — don’t skip it, and don’t rush it.
Step 7 — Loosen and finish before serving
Right before serving, stir in the remaining reserved dressing a spoonful at a time until the texture looks creamy again — the noodles will have soaked up a lot of moisture overnight. Top with sliced green onion.
Pro Tips for Perfect Hawaiian Bros Pasta Salad
Tip 1: Overcook the macaroni — genuinely, on purpose. This isn’t a typo carried over from a bad recipe. Firm noodles won’t absorb the dressing the way soft ones will, and that absorption is the entire texture the recipe is built around.
Tip 2: Squeeze the grated onion dry. Grated onion releases a surprising amount of liquid. Skipping this step is the most common reason a homemade batch turns out thinner and less creamy than the restaurant version.
Tip 3: Reserve some dressing for the next day. The noodles will drink up more dressing than you’d expect overnight. Holding back a third of it lets you fix the texture right before serving instead of guessing at the start.
Tip 4: Salt it again after chilling. Cold dressing reads as less salty than warm dressing. Taste again after the overnight rest and adjust — it usually needs a small pinch more than you think.
Variations and Substitutions
Dietary Variations:
- Gluten-free: Swap in a gluten-free elbow macaroni. Cook it slightly softer than the package’s al dente time, same as the wheat version — GF pasta can go from soft to mushy faster, so check it a minute earlier than you would regular macaroni.
- Lighter version: Replace half the mayo with plain Greek yogurt. The tang increases slightly and the texture stays creamy, though it won’t taste quite as rich as the original.
Flavor Variations:
- Add-ins: A cup of diced ham or cubed Spam turns this into more of a full plate-lunch side, closer to what’s often served alongside it at Hawaiian Bros.
Ingredient Substitutions:
- Apple cider vinegar works 1:1 in place of rice vinegar, though the flavor will be slightly sharper and less delicate.
- If you don’t have whole milk, half-and-half works and makes the dressing marginally richer.
If you’re building out a full plate-lunch spread, this sumac slaw is a good contrast on the side — it brings a bright, vinegary crunch that balances how rich the macaroni salad is.
Troubleshooting
My macaroni salad turned out watery instead of creamy?
This almost always comes down to the grated onion. Onion releases a lot of liquid as it sits, and if it isn’t squeezed dry before folding it in, that liquid thins the dressing over the resting period. Squeeze the grated onion in a paper towel next time before adding it.
The noodles are firm, not soft, even after chilling overnight?
The macaroni wasn’t cooked long enough. This recipe depends on noodles that are noticeably past al dente — about 2 minutes longer than the package instructs. Firm noodles won’t absorb dressing the same way, no matter how long they sit in the fridge.
The salad looks dry the next day?
This is normal, not a mistake — the noodles absorb a significant amount of dressing overnight. Stir in the reserved dressing, a spoonful at a time, until the texture looks glossy and creamy again before serving.
Storage and Make-Ahead
Counter: Don’t leave this out longer than 2 hours total — it’s mayo-based and needs to stay cold.
Refrigerator: Store in an airtight container for up to 4 days. The texture continues to firm up slightly each day; loosen with a splash of milk or a spoonful of mayo before serving leftovers.
Freeze: Not recommended. Mayo-based dressings separate and turn grainy once frozen and thawed.
Reheating: This is a cold salad — no reheating needed. Just bring it to room temperature for about 15 minutes before serving if it’s very cold.
Make-Ahead: This is genuinely a make-ahead recipe, not just a “can be made ahead” one — it’s better the next day. Make it up to 2 days before you need it.
Frequently Asked Questions
Q: What makes this different from a regular macaroni salad recipe? A: The macaroni is deliberately overcooked and the dressing includes milk in addition to mayo, which is what gives Hawaiian-style macaroni salad its signature soft, creamy texture instead of the firmer bite of a mainland pasta salad.
Q: Can I make this hawaiian bros macaroni salad recipe the day before a party? A: Yes — you should. The texture and flavor actually improve overnight as the noodles absorb the dressing. Just hold back some dressing to stir in right before serving.
Q: Why is my hawaiian bros macaroni salad so sweet? A: The sugar and rice vinegar are meant to balance each other into a distinct sweet-tangy flavor that’s characteristic of Hawaiian-style macaroni salad. If you’d prefer it less sweet, start with half the sugar and adjust to taste.
Q: Can I use a different pasta shape? A: Elbow macaroni is traditional and holds the dressing best because of its shape, but small shells or ditalini will also work with the same overcooking technique.
Q: Is this the same as Hawaiian potato-mac salad? A: It’s closely related — some Hawaiian plate lunch spots blend in mashed potato for extra creaminess. This version sticks to macaroni only, which is closer to what Hawaiian Bros specifically serves.
Q: How far ahead can I grate the carrot and onion? A: Up to a day ahead. Store them separately in the fridge in airtight containers, and squeeze the onion dry again just before folding it into the salad, since it will release more liquid as it sits.

Instructions
- Bring a large pot of salted water to a boil. Cook the elbow macaroni about 2 minutes past the package’s al dente time, until noticeably soft.
- Drain the macaroni and let it sit in the colander for 5 minutes, tossing once, until warm but no longer steaming.
- In a small bowl, whisk together the mayonnaise, milk, rice vinegar, sugar, salt, and pepper until smooth and glossy. Reserve about ⅓ of the dressing.

- Before serving, stir in the reserved dressing a spoonful at a time until creamy. Taste and add a pinch more salt if needed. Top with sliced green onion.
Notes
- Squeezing the grated onion dry before adding it prevents a watery dressing — this is the step most homemade versions skip.
- The salad will absorb dressing significantly overnight; always hold some dressing back to loosen it before serving rather than adding it all upfront.
- Store leftovers in an airtight container in the fridge for up to 4 days; do not freeze, as the mayo-based dressing separates when thawed.
