For best results, cook the pasta just to al dente so it holds its shape and doesn’t become mushy as it absorbs the dressing in the fridge; be sure the macaroni is fully cooled and well-drained before mixing, or the dressing will thin out and slide off. Finely chopping the celery and onion gives a better texture and ensures some crunch and flavor in every bite, and you can briefly soak chopped onion in cold water to mellow its sharpness. This salad keeps well for up to 3 days in the refrigerator, making it great for preparing ahead, but always keep it chilled and avoid leaving it at room temperature for long periods, especially for picnics or potlucks.
