Can I make macaroni salad ahead of time?
Yes, prepare it up to 1 day in advance. Store covered in the refrigerator; the flavors deepen as it sits. Add a splash of mayo or vinegar before serving if the salad dries out.
How do I keep the macaroni from getting mushy?
Cook the pasta 1–2 minutes under the package's recommended time so it's al dente, then drain and cool completely before mixing with the dressing.
What can I substitute for mayonnaise?
Use Greek yogurt mixed with a bit of extra vinegar for tang, or a combination of mayo and sour cream (75/25 ratio) for a lighter version.
Can I double this recipe?
Yes. Double all ingredients, but taste the dressing before adding the full amount of salt—mayo and relish already contain salt.
How long does macaroni salad keep?
Store covered in the refrigerator for 3–4 days. The pasta will continue to absorb dressing, so stir in extra mayo if needed before serving.
