Bring a large pot of salted water to a rolling boil, then add the macaroni and cook according to package directions until al dente—usually about 8-9 minutes. I always use Barilla because it holds its texture perfectly in a cold salad. Drain the pasta in a colander, then rinse thoroughly with cold water while tossing gently to stop the cooking process and remove excess starch. This keeps the pasta from becoming mushy as it sits in the dressing.

While the pasta cooks, finely dice the red onion into 1/8-inch pieces—this small size helps the flavor distribute evenly throughout the salad rather than having big chunks. Dice the celery stalk into similar small pieces and dice the green bell pepper into uniform 1/4-inch pieces. Set all vegetables aside on a cutting board; uniform sizing ensures even flavor distribution and better texture in every bite.

In a large mixing bowl, combine the mayonnaise, yellow mustard, vinegar, sugar, salt, black pepper, garlic powder, onion powder, and paprika. Whisk together until smooth and well combined, making sure the spices are evenly distributed throughout the creamy base. I prefer Hellmann's mayonnaise for its classic flavor, and I use Heinz white vinegar for that sharp, clean tang that brightens the whole dish.

Add the diced onion, celery, and bell pepper from Step 2 to the dressing base from Step 3. Stir well to coat all the vegetables evenly. This step should take just a minute or two to ensure the vegetables are fully incorporated and beginning to marinate in the flavors.

Add the cooled macaroni from Step 1 to the vegetable-dressing mixture. Fold together gently but thoroughly, using a rubber spatula to combine everything evenly without breaking the pasta. Add about half of this combined mixture back into the bowl, reserving the remaining half of the dressing separately—this two-stage dressing approach prevents the pasta from becoming oversaturated and keeps it from getting mushy during the chill time.

Transfer the partially dressed pasta to a covered container and refrigerate for at least 2 hours—this allows the flavors to meld and the pasta to absorb the dressing gradually. Just before serving, stir in the reserved dressing from Step 5 and fold gently to combine. This method ensures the salad stays creamy and the pasta maintains its texture rather than becoming heavy and oversaturated.
