Hawaiian Macaroni Salad Recipe With Tuna: Al Dente Pasta With Sweet Pea Crunch

This Hawaiian macaroni salad brings authentic island flavors to your table with minimal effort. The combination of al dente pasta, sweet peas, and flaky tuna creates a texture that’s both hearty and refreshing.

I’ve perfected this version by balancing creamy dressing with crisp vegetables for that signature Hawaiian plate lunch experience. The secret is in the ratio of mayonnaise to vinegar, which keeps it rich without being heavy.

What results is a side dish that’s creamy yet light, with just enough sweetness from the peas and a subtle tang from the dressing. It’s a crowd-pleaser that pairs perfectly with grilled proteins or as part of a picnic spread.

Serve chilled for best results, allowing the flavors to meld completely. This salad keeps well for days, making it ideal for meal prep.

Ingredients for Hawaiian Macaroni Salad Recipe with Tuna

Pantry staples plus a couple fresh veggies. Nothing complicated here.

The tuna is key here—Bumble Bee or Starkist in water works best (not oil, which can make the salad greasy). Barilla or De Cecco elbow macaroni holds its shape well after cooking. For the peas, frozen is actually better than canned—sweeter and less mushy. Most grocery stores carry everything you need, but Costco has great bulk pricing on tuna and mayo if you’re making this often.

No tuna? Chickpeas or shredded chicken can stand in, though it won’t be quite the same. Fresh peas work if they’re in season (blanch them first). The vinegar can be apple cider for a fruitier note, but white keeps the color cleaner. If you’re out of celery, bell pepper adds a nice crunch—just keep the ratio of veggies to pasta similar.

This salad actually gets better after a day in the fridge. Store in an airtight container for up to 5 days. The dressing might thicken slightly—just stir in a splash of milk if needed before serving. Perfect for meal prep or potlucks.

Step-by-Step Instructions for Hawaiian Macaroni Salad With Tuna

Here’s my foolproof method for creamy, crunchy salad with perfect texture every time.

Step 1: Cook and Cool the Elbow Macaroni

Boil the 12 oz Elbow Macaroni in salted water until just al dente—about 1 minute less than package instructions. You want it slightly firm so it holds up to the creamy dressing without turning mushy.

Drain immediately and rinse under cold water to stop the cooking process. Spread the pasta on a baking sheet and let it cool completely to room temperature. This prevents the mayonnaise from thinning out when mixed with hot pasta.

Step 2: Prepare and Combine the Vegetables

Finely dice the 2 whole Carrots and 2 pieces Celery, and mince the 0.5 whole Yellow Onion. I like to use a food processor for the carrots and celery to get perfectly even pieces, but a sharp knife works just fine.

Thaw the 1 cup Frozen Sweet Peas under cold running water and drain well. In a large bowl, combine the cooled macaroni, diced vegetables, and peas. The peas add a subtle sweetness and pop of color that makes this dish special.

Step 3: Prepare the Tuna and Dressing

Drain the 2 cans Canned Tuna thoroughly and flake into a bowl. I press the tuna between paper towels to remove any excess moisture—this keeps your salad from getting watery.

In a separate bowl, whisk together the 1.5 cups Mayonnaise, 2 tbsp White Vinegar, 1 tsp Salt, 0.5 tsp Black Pepper, and 0.5 tsp Garlic Powder until smooth. The vinegar cuts through the richness of the mayo beautifully.

Step 4: Mix and Chill for Maximum Flavor

Add the flaked tuna to the bowl with the macaroni and vegetables. Pour the dressing over everything and fold gently with a spatula until every piece is evenly coated. Be careful not to overmix—the tuna should stay in nice flakes, not get mashed into the pasta.

Cover the bowl tightly with plastic wrap and refrigerate for at least 1 hour. This chilling time lets the flavors meld together and the pasta absorb some of the creamy dressing. I always make this the day before if possible—the flavor improves overnight.

Step 5: Garnish and Serve

Just before serving, thinly slice the 3 pieces Green Onions and sprinkle them over the top. The green onions add a fresh, oniony bite that brightens up the creamy salad.

Give the salad one final gentle stir to distribute the green onions throughout. Serve chilled in a large bowl or as a side dish with your favorite main course. The salad keeps beautifully in the refrigerator for up to 3 days, though it rarely lasts that long in my house!

Storing and Reheating This Dish

Refrigerator Storage

Transfer your salad to an airtight container once fully chilled. It stays fresh in the fridge for up to 5 days, though I find the flavors peak around day two. The dressing may thicken slightly—just stir before serving.

Freezing Tips

While not ideal due to texture changes, you can freeze this salad for up to 1 month. Use freezer-safe bags and squeeze out excess air. Thaw overnight in the fridge and stir in 1-2 tbsp milk to restore creaminess.

Reheating Not Recommended

This dish is best served cold straight from the fridge. Reheating can cause the mayonnaise to separate and the pasta to turn mushy. If you must warm it, use low heat and stir constantly. 🥗

Portioning for Meals

Divide into single-serving containers for easy grab-and-go lunches. I use 16 oz mason jars—they’re perfect for layering and keep everything fresh. Add a slice of lemon on top to prevent browning.

Reviving Leftovers

If your salad seems dry after storage, fold in 1-2 tbsp mayonnaise or a splash of vinegar. This brings back the creamy texture without diluting the flavor. Stir gently to avoid breaking the pasta. ❄️
