Prepare the Potatoes : Preheat your oven to 400°F (200°C). Scrub the potatoes, pat them dry, and cut into bite-sized pieces. Toss the potatoes with olive oil, spreading them in an even layer on a baking sheet. Place in the oven and bake for 20-25 minutes, or until they are golden brown and crispy to the touch. Allow them to cool slightly.

Add Flavor with Vinegar : Once cooled, place the baked potatoes in a large bowl. Drizzle them with apple cider vinegar, tossing gently to coat evenly.

Make the Dressing : In a separate bowl, mix the mayonnaise, sour cream (or Greek yogurt), kosher salt, and black pepper until smooth and creamy. Adjust seasoning to taste.

Combine Ingredients : Pour the dressing over the potatoes, tossing gently to coat. Add the chopped bacon, green onions, and shredded cheddar cheese, folding them in until everything is evenly distributed.

Chill and Serve : Cover and refrigerate for at least 1 hour to let flavors meld. Serve chilled, garnished with extra green onions or cheese if desired.
