Preheat your oven to 425°F. Line a cookie sheet with parchment paper and set it aside.
In three separate shallow bowls, prepare the flour, beaten eggs, and panko crumbs. Start by coating each asparagus spear in flour, shaking off the excess. Next, dip the spears into the egg mixture, allowing any excess to drip off. Finally, coat them with panko crumbs, shaking off the extra crumbs before placing them on the prepared cookie sheet, ensuring they have space between them.
Bake the asparagus in the oven for 12 to 15 minutes, or until they turn golden brown.
While the asparagus is baking, combine the Greek yogurt, sour cream, dill, garlic, onion powder, lemon juice, salt, and pepper in a mixing bowl. Stir well to create the creamy dill sauce.
Serve the crispy asparagus fries alongside the creamy dill sauce in small bowls for dipping or on a plate with the fries. Enjoy your crunchy, flavorful snack!
