Cook macaroni in salted boiling water until tender, then rinse under cold water and drain completely to keep the salad creamy and not watery.
Whisk together mayonnaise, mustard, sugar, vinegar, paprika, salt, and pepper until smooth and velvety to form the classic Amish-style dressing.
Combine cooked macaroni with chopped eggs, celery, red pepper, and onion in a large bowl so every bite has color, crunch, and flavor.
Pour the dressing over the macaroni mixture and gently fold until everything is evenly coated without breaking the pasta.
Taste and adjust sweetness, salt, or tanginess to match the traditional Amish balance of sweet and savory.
Cover the bowl and chill for at least 1 hour so the flavors blend and the dressing thickens beautifully.
Serve cold alongside warm comfort dishes like Carrot and Parsnip Soup for a complete, satisfying meal.
