Preheat the oven 400 degrees.
In a bowl, add the salmon fillet. Squeeze the juice of one lemon on the fish. Add cold tap water to cover the fish. Allow the fish to sit in the lemon water for 15 minutes.
Rinse the salmon with cold water. Pat dry with paper towel. Season the fillet with one tablespoon of the chopped dill, one teaspoon salt, 1/2 teaspoon black pepper, 1/2 teaspoon paprika and one tablespoon olive oil. Gently rub the season all over the fish. Set aside.
In a large tin foil pan or large sheet pan, add the carrots, potatoes, onions, leeks, dill, garlic, fennel seeds, one teaspoon paprika, one teaspoon salt, one teaspoon fresh ground black pepper and the extra virgin olive oil. Coat the vegetables with the spices and oil and spread the veggies in a single layer on the pan.Note: If using a sheet pan, line it with parchment paper - makes for easy clean up. Roast the vegetables in the oven for 25 minutes. Add the wine and stir to coat the vegetables. Cover the pan with tin foil and allow the vegetables to continue to cook for 20 minutes.
Remove the pan from the oven. The vegetables should be nice and tender - use a fork to pierce the potato to ensure it is tender. Place the salmon in the center of the vegetables - you can either place the fish right on top of the vegetables or use a spatula to move some of the vegetables from the center of the pan and place the fish in the center. Add the lemon slices - a few pieces directly on the salmon and the remainder on the vegetables. Cover with the tin foil.
Place the pan back into the oven and continue cooking for 15 minutes. Remove the pan from the oven. Leave the pan covered and allow to rest for 10 minutes.
Plate and serve the salmon on a bed of the vegetables. Enjoy.
