01 - Preheat 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). Serve immediately while warm and crispy.
