Add potatoes to a Dutch oven filled with water and 1 T salt. Boil for about 25 minutes until potatoes are tender with fork inserted. NOTE: the size of your potatoes will determine length of time to make them soft enough to smash. Preheat oven to 425℉.
Line a half sheet baking pan with sides with parchment paper and coat with olive oil.
Drain cooked potatoes and add to prepared baking sheet.
Use a bottom of a glass to smash each potato.
Melt butter for a few seconds in the microwave.
Drizzle potatoes with melted butter and sprinkle with salt, pepper and garlic powder or garlic salt.
Add to preheated oven.Set a timer for 30 minutes to turn over about halfway through to cooking time to keep crispy on both sides.Continue to cook for an additional 30 minutes or until potatoes are as crisp as you like. While potatoes are roasting, cook bacon, drain, and chop. Set aside.
Combine a dash of salt and pepper with mayonnaise, sour cream, mustard, and lemon juice, to create the dressing.
Thinly slice the green onions.
Reserve 1 T green onions and 1 T of chopped bacon for topping the potato salad.
When potatoes have cooled on baking sheet, remove and add to cutting board and roughly chop.
Add the potatoes to a large mixing bowl. Then add the green onions, chopped bacon and dressing and stir until coated. NOTE: Taste for seasoning at this point. Add potato salad to a serving bowl and top with the reserved bacon and green onions. Garnish with fresh dill or parsley if you like.
Serve immediately and refrigerate leftovers. Enjoy!
NOTE: To serve refrigerated leftovers, if they seem dry, spray with a little water, cover and microwave for a couple of minutes to warm to bring this back to a great consistency.
