Loaded Potato Salad 
Active Time: 30 mins
Total Time: 1 hr 15 mins
Servings: 8
Ingredients:
3 lb. russet potatoes, peeled and cut into 1-in. pieces (about 7 cups)
1 1/4 cups mayonnaise
1 1/4 cups sour cream
1 Tbsp. distilled white vinegar
1 1/4 tsp. kosher salt
3/4 tsp. granulated sugar
3/4 tsp. black pepper
1/2 tsp. celery seed
1/2 cup finely chopped red onion (from 1 small [4 oz.] onion)
1/2 cup finely chopped celery (from 3 large stalks)
10 thick-cut bacon slices, cooked and coarsely chopped (about 1 cup), divided
9 oz. sharp Cheddar cheese, shredded (about 1 1/2 cups), divided
1/2 cup sliced scallions (from 2 large scallions), divided
Directions:
Step 1. Cook the potatoes: Boil in salted water until tender. Then drain them and spread them on a baking sheet to cool slightly. Chill the potatoes in the fridge until they’re completely cooled.
Step 2. Make dressing: In a separate bowl, combine mayonnaise, sour cream, vinegar, salt and pepper, sugar, and celery seed.
Step 3. Finish potato salad: Add to the dressing the cooled potatoes and red onion, plus some of the bacon, cheese, and scallions. Chill the potato salad for about 30 minutes.
Step 4. Garnish and serve: Once chilled, finish the potato salad with the remaining bacon, cheese, and scallions. Serve immediately.
Notes:
How much potato salad per person?
As a rule of thumb, allow about a half cup of potato salad per person. For more generous portion sizes, allow about three-quarters cup per person.
Can potato salad be frozen?
Potato salads made with mayonnaise don’t tend to fare well in the freezer. That’s because the freezing and thawing changes the texture of the dairy ingredients, so the consistency of the salad changes, too.
How long can potato salad sit out?
Potato salad is perishable and cannot sit out for more than two hours. If the temperatures are hot and you’re outside, it can only sit out for closer to one hour.
