A creamy, tangy Hawaiian-style macaroni salad made with tender pasta, shredded carrot, and a simple mayonnaise-milk dressing. Great for potlucks and plate lunches.
Bring a large pot of salted water to a boil. Cook the macaroni until al dente. Drain and rinse under cold water until the pasta is cool. Toss with a touch of oil or a tablespoon of dressing to prevent sticking.
Whisk together mayonnaise, milk, vinegar, sugar, salt, and pepper until smooth. Adjust seasoning to taste.
In a large bowl, mix pasta with carrot, onion, peas, and relish. Fold in the dressing until evenly coated. Cover and refrigerate at least 30 minutes, ideally 2–4 hours.
Toss again before serving, garnish with chopped green onion if desired, and serve chilled.
Notes
Make-ahead: Salad stores well for up to 24 hours; add extra dressing if absorbed.
Substitutions: Swap half the mayo for Greek yogurt for a lighter version.
Dairy-free: Use plant-based mayo and thin with water if needed.
