Preheat the oven to 375 degrees F. Mix the maple syrup and dark brown sugar in a small bowl.
Line a baking sheet with aluminum foil and set a rack on stop. Put the bacon on the rack leaving space between the strips. Brush with the maple syrup mixture and then sprinkle some fennel seeds on top¿fennel is a strong spice so use it sparingly. Season with black pepper.
Bake until brown and crisp, 20 to 25 minutes. Loosen the bacon from the rack and let it cool there 5 minutes before serving.
