Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper. Spread the raw or frozen fries in an even layer on the baking sheet. Bake for 15 minutes until golden brown and crispy.
While the fries are baking, cook the bacon in a skillet over medium heat until crispy. Remove, drain on paper towels, then crumble into small pieces. Slice the pickled jalapeños into thin rings.
2 cups frozen or fresh-cut fries
Once the fries are done, remove from the oven and sprinkle shredded cheddar cheese evenly over hot fries. Return to the oven and broil for 2-3 minutes until the cheese is melted and bubbly, watching closely to prevent burning.

Remove the baking sheet from the oven and evenly distribute crispy bacon crumbles and pickled jalapeño slices over the cheesy fries. Drizzle with a small amount of vegetable oil or hot sauce if desired. Season with salt and pepper to taste.

Serve immediately on plates or in bowls, allowing the cheese to ooze and toppings to be visibly melty and colorful. Enjoy the messy, flavorful dish with a fork or hands.
