Asparagus with Bacon-Hazelnut Vinaigrette and Slow-Cooked Egg Recipe

Preheat water oven to 142°F. Place eggs in water bath and cook at least 45 minutes, and up to 4 hours. Meanwhile, place bacon in heavy-bottomed 10-inch skillet and cover with 1/2 cup water. Place over burner on medium high heat and cook, stirring occasionally until water has evaporated and bacon has crisped, about 10 minutes. Transfer bacon and fat to medium bowl. Add hazelnuts, honey, mustard, olive oil, and vinegar. Whisk vigorously to combine. Season to taste with salt and pepper. Set aside. Bring 4 quarts of water with 4 tablespoons kosher salt to a rolling boil in large Dutch Oven. Add peeled asparagus and cook until bright green and tender but still crisp, 2 to 5 minutes depending on thickness. Drain asparagus and set on serving plate. Carefully crack cooked egg, and using fingertips, create a hole about 1-inch in diameter. Pour egg into small bowl, then carefully set on top of asparagus. Repeat with remaining eggs. Drizzle eggs and asparagus with bacon hazelnut vinaigrette and serve immediately.
