Preheat your oven to 200°C (390°F). Lightly drizzle a baking dish with a tablespoon of olive oil to prevent sticking.
Pat the cod fillets dry with paper towels, then season generously with salt and pepper on both sides. Place them skin-side down in the prepared dish.
In a small bowl, whisk together minced garlic, lemon zest, lemon juice, and olive oil until well combined. This mixture will add bright flavor and aroma to the fish.
Spoon the garlic-lemon mixture evenly over each fillet, spreading it gently with the back of a spoon to coat the fish thoroughly.
Lay thin slices of lemon on top of each fillet for extra flavor and a pretty presentation.
Bake in the preheated oven for 12-15 minutes. The fish should turn opaque and flake easily when tested with a fork. You’ll hear a gentle sizzling and smell a fragrant citrus aroma as it bakes.
Check the internal temperature with a thermometer; it should read about 60°C (140°F). If it’s ready, the edges will be lightly golden and the fish will be firm yet tender.
Once done, remove the baking dish from the oven and let the fish rest for 2-3 minutes. This helps the juices settle and keeps the fish moist.
Garnish the fillets with chopped fresh herbs and a squeeze of fresh lemon juice for extra brightness.
Serve the baked cod immediately, accompanied by your favorite greens or grains. Enjoy the flaky, flavorful fish with its crispy edges and bright citrus notes!
