Classic Macaroni Salad

Gather all ingredients.

Bring a large pot of lightly salted water to a boil. Cook macaroni pasta in the boiling water, stirring occasionally, until tender yet firm to the bite, about 8 minutes. Rinse under cold water and drain.

Mix mayonnaise, sugar, vinegar, mustard, salt, pepper, and macaroni pasta together in a large bowl.

Stir in celery, onion, green pepper, carrot, and pimentos.

Refrigerate salad for at least 4 hours before serving, but preferably overnight.
