Using a microwave-safe container, cover and microwave the baby potatoes for 10 to 12 minutes or until they are fork-tender. If they are not tender, the potatoes will not smash. Stir the potatoes halfway through the cooking time.
After cooking, drain and gently toss potatoes with salt and pepper.
Preheat the Blackstone to medium heat.
Pour the avocado oil on the flat top. Using a large spatula, spread the oil out.
Carefully, pour the potatoes into the oil on the flat top.
With a burger press or bacon press and a piece of parchment paper, smush the potatoes until flattened.
Grill the baby potatoes until crispy, about 10 minutes. Flip and cook the other side.
Remove from the grill and top with shredded cheese and crumbled bacon. Drizzle with sour cream and sprinkle the chopped green onions over the potatoes.
Serve the potatoes right away.
Notes
