This is our favorite macaroni salad that features tender elbow macaroni mixed with bright veggies like red onions, celery, bell peppers, some herbs, and delicious creamy dressing. The dressing is smooth and flavorful made with mayo, sour cream, Dijon mustard, white wine vinegar, brown sugar, garlic powder, salt, and black pepper.
Cook pasta in salted water according to box instructions, until cooked al dente.
Drain cooked pasta and let it cool until no longer scalding hot. Gently fluff it from time to time while it cools.
Dice all vegetables and herbs while pasta is cooking and whisk all ingredients for the dressing in a separate bowl.
In a large mixing bowl, combine pasta vegetables, and herbs and mix.
Pour dressing into the bowl with the pasta and mix everything together until dressing is evenly incorporated throughout.
Cover the bowl with plastic wrap or transfer the salad into a food storage container with a lid. Refrigerate for at least 2 hours before serving.
