How to Make Mediterranean Baked Fish

Ingredients

  • 4 fillets of cod, halibut, snapper, or sea bass (about 6 oz each)
  • 2 cups cherry tomatoes, halved
  • ½ cup Kalamata olives, pitted and sliced
  • 1 medium red onion, thinly sliced
  • 3 cloves garlic, minced
  • 3 tbsp extra virgin olive oil
  • Juice of 1 lemon
  • 1 tsp dried oregano
  • 1 tsp fresh basil or parsley, chopped
  • Salt and pepper to taste

Step-by-Step Instructions

  1. Prep Fish: Pat the fish fillets dry with paper towels. Lightly season them with salt, pepper, and a drizzle of olive oil.

  2. Make Topping: In a bowl, combine the halved cherry tomatoes, sliced olives, thinly sliced red onion, minced garlic, dried oregano, lemon juice, and extra virgin olive oil. Toss well.

  3. Bake: Place the seasoned fish fillets in a baking dish. Spoon the tomato-olive mixture over the top. Bake in a preheated oven at 400°F (200°C) for 20–25 minutes, or until the fish flakes easily with a fork.

How to Store Mediterranean Baked Fish

If you have leftovers, store them in an airtight container in the refrigerator. The Mediterranean Baked Fish can last for up to 3 days in the fridge. To reheat, place the fish in a baking dish and warm it at a low temperature in the oven until heated through. Avoid using the microwave, as it can make the fish rubbery.

Tips to Make Mediterranean Baked Fish Perfect

  • Choose Fresh Fish: Freshness is key to a great dish. Select fish fillets that have a mild scent and firm texture.
  • Don’t Overcook: Keep an eye on the cooking time. Overcooked fish can become dry, so check for flakiness at around 20 minutes.
  • Customize the Toppings: Feel free to add other ingredients like capers, artichoke hearts, or even zucchini for added flavor and nutrition.

Flavor Variations

You can customize this Mediterranean Baked Fish recipe to suit your taste preferences. Try adding different herbs like dill or tarragon. For a spicy kick, include some red pepper flakes. If you enjoy citrus flavors, orange zest can replace lemon juice for an interesting twist. Additionally, swap olives for sun-dried tomatoes or replace cherry tomatoes with diced bell peppers for variation.

Pro Tips for Success

  • Use a Meat Thermometer: If you want to ensure your fish is perfectly cooked, use a meat thermometer. The internal temperature should reach 145°F (63°C).
  • Let It Rest: After taking the dish out of the oven, let the fish rest for a few minutes to allow juices to redistribute.
  • Experiment with Different Fish: While cod and halibut are popular options, you can use any firm white fish or even salmon for a different flavor profile.
