Preheat the oven to 400°F (200°C).
Season the haddock fillets with salt, pepper, lemon juice, and minced garlic.
Wrap each haddock fillet tightly in aluminum foil and place them on a baking sheet.
Bake in the preheated oven for 15-20 minutes, until the fish is cooked through and flakes easily with a fork.
While the fish is baking, use a vegetable peeler to create long ribbons from the zucchinis.
Heat olive oil in a skillet over medium heat. Add the zucchini ribbons and sauté for 3-4 minutes, until tender.
Serve the baked haddock fillets on top of the sautéed zucchini ribbons.
Enjoy!
