Diner-Style Home Fries

1. Heat 1 tablespoon oil in 12-inch skillet over medium-high heat until shimmering. Add onion and cook, stirring frequently, until browned, 8 to 10 minutes. Transfer to small bowl; set aside.
2. Meanwhile, place potatoes and 1 teaspoon salt in large saucepan, cover with 1⁄2 inch water, and bring to boil over high heat. As soon as water begins to boil, drain potatoes thoroughly in colander.
3. Heat remaining 1-1⁄2 tablespoons oil and butter in now-empty skillet over medium-high heat. Add potatoes and shake skillet to evenly distribute potatoes in single layer, making sure 1 side of each piece is touching skillet. Cook without stirring until potatoes are golden brown on bottom, about 4 to 5 minutes, then carefully turn potatoes, making sure potatoes remain in single layer. Repeat process until potatoes are tender and browned on most sides, turning 3 to 4 times, 10 to 15 minutes. Stir in onion, paprika, remaining 1⁄4 teaspoon salt, and pepper to taste and serve.
