Skillet Hamburgers With Oven Fries

• 4 large russet potatoes, peeled (about 2 1/2 lb.)
• 2 tablespoons vegetable oil, plus extra for greasing
• 1 12 lbs ground round
• salt
• fresh ground black pepper
• 4 hamburger buns, split (or onion rolls)
• ketchup
• mayonnaise
• mustard
• sliced tomatoes
• lettuce
• sliced red onion

1. Preheat the oven to 400.
2. Using a French-fry cutter or sharp knife, cut each potato lengthwise into long strips about 1/2-inch thick.
3. Toss with the 2 tablespoons oil and spread in a single layer on a large baking sheet.
4. Bake, occasionally scraping up the potatoes with a metal spatula, until the fries are golden brown, about 1 hour; transfer to paper towels to drain.
5. Just before the fries are done, lightly oil the bottom of a large cast-iron frying pan.
6. Place the pan over med-high heat and heat until very hot.
7. While the pan is heating, in a bowl, using clean hands, lightly mix together the ground beef, 1 tsp salt, and 1/2 tsp pepper.
8. Handling the seasoned beef as little as possible, form into 4 plump patties, each about 4 inches in diameter.
9. Place the burgers in the hot frying pan.
10. Cook until browned on the first side, about 3 minutes.
11. Turn and cook until browned on the second side, about 3 minutes longer for medium burgers.
12. While the burgers are cooking, toast the buns in a toaster or under a broiler, cut side up, for about 1 minute.
13. Season the hot oven fries to taste with salt and pepper.
14. Place each burger on a bun.
15. Serve at once, with the fries.
16. Pass the ketchup, mayonnaise, mustard, tomatoes, lettuce, and onion at the table.
