01 - Preheat oven to 425°F. Toss potato fries with vegetable oil, salt, and black pepper until evenly coated. Arrange fries in a single layer on a baking sheet. Bake for 25 to 30 minutes, flipping halfway through cooking, until golden brown and crispy.
02 - While potatoes are roasting, cook bacon slices in a skillet over medium heat until crisp. Transfer cooked bacon to a paper towel-lined plate to drain. Coarsely chop the bacon once cooled.
03 - Melt unsalted butter in a small saucepan over medium heat. Whisk in all-purpose flour and cook for 1 minute to form a roux. Gradually whisk in beef or chicken stock and Worcestershire sauce. Simmer for approximately 5 minutes, stirring constantly, until gravy thickens. Season with salt and pepper to taste.
04 - Fry or poach 4 large eggs to your preferred doneness. Keep warm until ready to assemble.
05 - Distribute crispy fries evenly among 4 plates. Top with cheese curds and pour hot gravy over the fries to partially melt the curds. Add chopped bacon and gently place a cooked egg on each serving. Garnish with fresh chives if desired. Serve immediately.
