Ingredient Breakdown

The pasta is the heart of this dish, and the key is to cook it just until al dente. Pasta that’s too soft won’t hold up once coated in dressing. Elbow macaroni works best because its shape cradles the dressing perfectly, ensuring every bite is coated in creamy goodness.

The dressing is what defines a great macaroni salad — smooth, tangy, and ever so slightly sweet. The combination of mayonnaise and sour cream forms a luscious base, while dry mustard and cider vinegar cut through with a mild sharpness. Sugar rounds out the flavors, giving the salad a balanced profile that’s both savory and refreshing.

The vegetables add brightness and crunch. Celery brings a crisp snap, red onion offers a subtle bite once soaked in cold water, and parsley infuses a hint of freshness. The optional addition of vine-ripened tomatoes adds color and a juicy burst that complements the creaminess. Altogether, these ingredients transform a simple pasta salad into something vibrant and well-balanced.

Step-by-Step Preparation Guide

Cooking the pasta is the first step toward achieving the perfect texture. Always salt the water generously — it’s your chance to season the pasta from within. Once cooked, rinse it under cold water to stop the cooking process and remove excess starch that might make the salad heavy. Cooling the pasta completely before mixing ensures the dressing adheres evenly without breaking down.

The vegetables require minimal preparation but make a major impact. Soaking the red onion in cold water for a few minutes mellows its bite, while finely dicing the celery ensures consistent crunch throughout. Chopping the parsley adds color and a clean herbal note that cuts through the richness of the dressing.

For the dressing, whisk together mayonnaise, sour cream, vinegar, mustard, sugar, and salt until smooth and emulsified. This blend should taste balanced — tangy but not overpowering, creamy yet not overly heavy. Once ready, pour it over the pasta mixture and gently fold until everything is evenly coated. A light hand ensures the macaroni stays intact and the vegetables retain their crispness. Chill the salad for at least 30 minutes to allow the flavors to harmonize and the dressing to thicken slightly.

Ingredients

2 cups dry elbow macaroni, cooked, rinsed, and drained
3 tablespoons sour cream
½ cup prepared mayonnaise
1½ tablespoons cider vinegar
¾ teaspoon dry mustard
1½ teaspoons sugar
½ teaspoon kosher salt, plus more to taste
Freshly ground black pepper, to taste
⅓ cup diced celery
¼ cup minced red onion, soaked in cold water for 5 minutes, then drained
1 tablespoon minced flat-leaf parsley
½ cup diced vine-ripened tomato (optional)

Instructions

Cook the elbow macaroni in salted boiling water according to package directions until al dente. Drain well, rinse under cold water to stop the cooking process, and set aside to cool completely.

In a large mixing bowl, combine the cooled macaroni with diced celery, red onion, parsley, and tomato, if using. Toss lightly to distribute the ingredients evenly.

In a separate smaller bowl, whisk together the mayonnaise, sour cream, cider vinegar, dry mustard, sugar, and salt until smooth and creamy. This dressing should be tangy yet balanced with a touch of sweetness.

Pour the prepared dressing over the macaroni mixture and gently fold until every piece is well coated. Taste and adjust with additional salt and freshly ground black pepper as desired.

Chill the salad for at least 30 minutes before serving to allow the flavors to meld and the dressing to slightly thicken. Serve cold as a refreshing side dish — perfect for picnics, barbecues, or casual family gatherings.
