In a shallow dish, combine the milk, minced garlic, olive oil, lemon juice, salt, and pepper. Stir until well mixed.
Place the salmon fillets in the marinade, making sure they are fully coated. Cover the dish with plastic wrap and refrigerate for at least 1 hour and up to 4 hours.
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Remove the salmon fillets from the marinade and place them on the prepared baking sheet. Discard the remaining marinade.
Bake the salmon for 12 to 15 minutes, or until the fish is cooked through and flakes easily with a fork.
Garnish with fresh parsley or dill, or citrus slices, if desired. Serve and enjoy!
Note: You can also grill or pan-fry the fish if you prefer.
