Advices
Advice
Choose tomatoes that are juicy yet firm. Soft ones lose shape during slicing and cooking, turning into mush and spoiling the dish’s appearance.
Preparation
Step 1
You can use fresh or frozen pollock. If using frozen, thaw it first by placing it in the refrigerator (not at room temperature). You can also use whole fish instead of fillet - just clean and cut it into serving portions.
Step 2
Rinse the pollock fillet, pat it dry, and cut into medium-sized pieces. You may substitute it with any red or white, freshwater or saltwater fish you like.
Step 3
Wash and dry the tomatoes, then cut them into wedges. If using cherry tomatoes, cut them in half.
Step 4
Peel the onions and slice them into thin half-rings. Red onions can be swapped with yellow or shallots.
Step 5
Prepare the marinade. You can customize the spices. Use any vegetable oil (olive oil is preferred).
Step 6
In a bowl, mix olive oil, lemon juice and zest, garlic passed through a press, dried thyme, ground black pepper, and salt. Mix thoroughly.
Step 7
Pour the marinade over the fish and let it marinate for 30 minutes.
Step 8
Grease a baking dish with olive oil. Place the onion in an even layer on the bottom, then spread the tomato slices on top. Drizzle with olive oil, sprinkle with salt and pepper. Bake in a preheated oven at 180°C (350°F) for 20 minutes.
Step 9
After 20 minutes, remove the dish from the oven and gently place the marinated fish on top of the vegetables. Return to the oven and bake for another 15–20 minutes, or until the fish is cooked through and flaky.
Step 10
Garnish the baked fish with fresh parsley and serve. Enjoy your meal!
