01 - Preheat your oven to 425°F. Line a baking sheet with parchment paper.
02 - Place baby potatoes in a large pot, cover with water, and bring to a boil. Add salt and cook until fork-tender, 15-20 minutes.
03 - Drain potatoes and let cool slightly. Arrange on the prepared baking sheet.
04 - Use a glass or potato masher to gently smash each potato to about 1/2 inch thickness.
05 - Drizzle the smashed potatoes generously with olive oil; season with salt and pepper. Bake 20-25 minutes or until golden and crispy.
06 - Mix sour cream, mayonnaise, dill, chives, garlic powder, onion powder, lemon juice, salt, and pepper in a bowl until smooth. Chill until ready to use.
07 - Remove potatoes from oven. Spread or drizzle ranch sauce over each potato. Sprinkle with chopped dill pickles, jalapeños (if using), fresh herbs, and parmesan (if desired).
08 - Serve immediately while warm and crispy.
