This classic macaroni pasta salad features a creamy homemade Italian dressing that clings to every curve of the elbow macaroni. It’s bright, tangy, and packed with crisp vegetables, making it the perfect potluck or meal prep dish that actually gets better after a day in the fridge.
For best results, cook pasta 1 minute less than al dente and rinse with cold water to stop cooking. Reserve about 1/4 cup of dressing to refresh the salad before serving if making ahead. The salad improves after a day in the fridge. To mellow red onion, soak diced onion in cold water for 10 minutes, then drain well before adding.
