Begin by bringing a large pot of salted water to a boil. Once boiling, add the elbow macaroni and cook according to the package instructions until al dente. Drain the macaroni and rinse it under cold running water to cool it down. Set aside.
In a large mixing bowl, combine the mayonnaise, sour cream, Dijon mustard, and apple cider vinegar. Use a whisk to blend the ingredients together until smooth and creamy.
Carefully fold in the finely chopped red and green bell peppers, red onion, celery, and diced dill pickles to the dressing mixture. Stir gently until all the vegetables are well-coated with the dressing.
Add the cooled elbow macaroni into the vegetable and dressing mixture. Stir thoroughly, making sure the macaroni is evenly coated in the flavorful dressing.
Next, gently fold in the shredded cheddar cheese, sliced green onions, garlic powder, and smoked paprika. Mix delicately to ensure an even distribution of flavors without breaking the macaroni.
Taste the salad and season it with salt and pepper according to your preference. Adjust the flavors as necessary to tailor it to your liking.
Cover the bowl with plastic wrap or a lid and refrigerate the macaroni salad for a minimum of 1 hour. This allows the flavors to meld beautifully.
Just before serving, give the salad a good final stir to reincorporate any ingredients that may have settled.
Notes
