• 1-1/4 to 1-1/2 lbs tilapia, or catfish, barramundi, snapper fillets
• Salt and freshly ground black pepper
• 2 tablespoons freshly squeezed lemon juice, divided
• 2-1/2 tablespoons olive oil, divided
• 6 cloves garlic, peeled and roughly chopped
• 1 lb zucchini, ends trimmed and quartered lengthwise (see notes)
• 8 plum tomatoes, ends trimmed and cut into 1/2-inch slices
• 1 to 2 tablespoons capers, rinsed and drained
• 2 tablespoons fresh parsley, chopped

• Preheat your oven to 425°F (220°C). Prepare a large rimmed baking sheet by coating it generously with nonstick spray or lining it with parchment paper for even easier cleanup.
• Season the fish fillets on both sides with a generous sprinkle of salt and freshly ground black pepper. Drizzle them with 1 tablespoon of the fresh lemon juice and a light coating of olive oil. Set the seasoned fish aside to allow the flavors to meld while you prepare the vegetables and topping.
• For the flavorful topping, add 2 tablespoons of olive oil to a small saucepan and place it over medium-low heat. Stir in the roughly chopped garlic. As soon as the oil begins to gently bubble around the garlic (this should take about 30 seconds), reduce the heat to low. Continue to cook the garlic slowly, ensuring it doesn’t brown, which can make it bitter.
• Periodically stir the garlic mixture in the saucepan to ensure even cooking and prevent any browning. The goal is to gently infuse the olive oil with a sweet, mellow garlic flavor.
• Cut the zucchini quarters in half crosswise, creating bite-sized pieces. Arrange these zucchini pieces in a single layer on your prepared baking sheet. Season them lightly with salt and pepper. Roast the zucchini in the preheated oven for 5 to 7 minutes to give them a head start and encourage caramelization.
• Carefully add the sliced plum tomatoes to the baking sheet with the zucchini, spreading them out in a single layer. Season the tomatoes with a pinch of salt and pepper. Return the pan to the oven and continue roasting for an additional 10 minutes, allowing the vegetables to further soften and caramelize.
• After the vegetables have roasted for a total of 15-17 minutes, place the seasoned fish fillets onto the sheet pan, making sure they are not overcrowded. Continue roasting for an additional 8 to 12 minutes, or until the fish is opaque throughout and flakes easily with a fork. Cooking time may vary depending on the thickness of your fish fillets.
• While the fish finishes cooking, return to your garlic and olive oil mixture. Add the remaining tablespoon of lemon juice, along with the rinsed and drained capers and the fresh chopped parsley. Turn up the heat for just a minute to gently warm the mixture through, then remove it from the heat and set it aside. This step ensures the fresh ingredients are incorporated just before serving, preserving their vibrant flavors.
• Once the fish and vegetables are cooked, carefully remove the sheet pan from the oven. Serve each fish fillet topped with a generous portion of the fragrant garlic-caper mixture. Arrange the roasted zucchini and tomatoes alongside the fish. Enjoy immediately!

To truly achieve a beautiful caramelization and tender texture on your zucchini, it’s beneficial to remove some of its excess moisture before roasting. To do this, after quartering the zucchini lengthwise, cut the quarters in half crosswise. Arrange these pieces, cut side up, on a flat surface (like a clean cutting board or a separate sheet pan) and sprinkle them generously with salt. Let them sit for about 10 minutes, or until you see small beads of liquid form on the cut surfaces. Then, simply blot the zucchini thoroughly with paper towels before proceeding with the recipe. This step helps the zucchini brown rather than steam in the oven. You can apply the same technique to your plum tomatoes if you wish to concentrate their flavors even further.

Important Note: If you choose to pre-salt your zucchini (and/or tomatoes) to draw out moisture, remember to significantly cut back on the amount of salt you use during the cooking process for the vegetables. This will prevent your dish from becoming overly salty. Always taste and adjust seasoning as needed before serving.

**Choosing Your Fish:** While tilapia is specified, this recipe is highly versatile. Consider other mild, flaky white fish fillets like cod, halibut, snapper, barramundi, or even thicker cuts of catfish. Adjust cooking times slightly based on the thickness of your chosen fish. Thicker fillets might require a few extra minutes of roasting.

**Don’t Overcrowd the Pan:** For optimal roasting and browning of your vegetables and fish, ensure a single layer on the baking sheet. If your pan is too crowded, the ingredients will steam instead of roast, leading to a less desirable texture. If necessary, use two baking sheets and rotate them halfway through cooking.

**Perfect Garlic:** When simmering the garlic for the topping, pay close attention to the heat. Garlic can burn quickly, turning bitter. Keep the heat low and stir frequently to achieve that lovely, mellow garlic flavor without any harshness.

**Herb Variations:** Feel free to experiment with other fresh herbs in your topping. Dill or oregano would also complement the Mediterranean flavors beautifully. A sprinkle of fresh mint could add an unexpected bright note.
