To cook potatoes in Instant Pot, add 2 cups of water, then place clean potatoes in a steamer basket, attach lid, set the vent to sealing, and set manual for 2 minutes. Once pressurized and the 2 minutes have passed, let it natural release for 5 minutes. Then turn valve to full release. Open lid and carefully remove the basket of potatoes. Let potatoes cool for 5 minutes in basket.• Other ways of cooking the potatoes include boiling, steaming, or microwave. Next, preheat oven to 425°F then line baking sheet with parchment paper. Place potatoes on parchment paper then smash down with a potato masher, metal spatula, or the bottom of a glass jar. Make sure to keep the potato in 1 piece. The thinner you smash the crispier. The thicker the fluffier in the middle. Melt butter then add 2 tbsp olive oil, stir. Using a pastry brush drizzle butter and oil mixture over each potato. Sprinkle potatoes with ranch powder. Bake for 25-35 minutes or until golden and crispy. Serve hot!
