Maltese Baked Tuna: A Taste of the Mediterranean

My grandmother, a woman who could coax flavor out of thin air, had a knack for simple dishes that spoke volumes. I remember one summer evening, the scent of ripe tomatoes and herbs wafting from her kitchen. She was making something she called “Tuna Bake,” a dish she picked up from a friend whose family hailed from Malta. It wasn’t fancy, but the tender tuna nestled amongst fragrant vegetables, infused with the warmth of olive oil and a hint of the sea, was unforgettable. It was a dish that tasted of sunshine and family, and to this day, it evokes memories of laughter-filled meals under the Mediterranean sun, even though we were miles away from it.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 45-60 minutes
• Total Time: 1 hour 5 minutes – 1 hour 20 minutes
• Servings: 4
• Yield: 1 baking dish
• Dietary Type: Pescatarian, Gluten-Free, Dairy-Free

Ingredients

• 1/4 cup extra virgin olive oil
• 3 small onions, diced
• Salt, to taste (Note: nutritional analysis for sodium will be incorrect; you must account for the salt you add!)
• Freshly ground black pepper, to taste
• 1 lb baking potatoes, peeled and thinly sliced
• 1 1/2 – 2 lbs tuna steaks, about 1/2 inch thick (usually around 4 steaks)
• 1 lb plum tomatoes, halved and cored
• 4 garlic cloves, crushed but left whole
• 1/2 cup water
• 1 tablespoon red wine vinegar
• 1/4 cup fresh mint, chopped
• 1/4 cup fresh parsley, chopped

Equipment Needed

• Baking dish (or slow cooker)
• Knife
• Cutting board
• Measuring cups and spoons
• Aluminum foil (if baking dish does not have a lid)

Instructions

1. Preheat your oven to 350°F (175°C).
2. Brush the sides and bottom of a baking dish with some of the olive oil. If you’re opting for a slow cooker, simply brush the bottom and lower part of the cooking bowl.
3. Scatter the diced onions evenly on the bottom of the prepared baking dish or slow cooker.
4. Season the onions with salt and pepper to taste. For an authentic touch, consider using sea salt or kosher salt.
5. Layer the thinly sliced potato slices to cover the onions. Ensure an even distribution for proper cooking.
6. Lightly season the potato layer with salt and pepper.
7. Continue alternating layers of onions and potatoes, seasoning each layer, until all the onions and potatoes are used up. The final layer should be potatoes.
8. Place the tuna steaks on top of the last layer of potatoes, arranging them evenly across the surface.
9. Cover the tuna steaks with the halved plum tomatoes, placing them cut-side down. This will allow their juices to release during cooking and infuse the dish with flavor.
10. Add the crushed (but whole) garlic cloves among the tomatoes. Their flavor will mellow as they cook, adding a subtle complexity.
11. Pour the water into the baking dish, ensuring it reaches the lower layers.
12. Drizzle the remaining olive oil and red wine vinegar evenly over the tomatoes.
13. Sprinkle the chopped fresh mint and parsley over the entire top of the dish, distributing the herbs for maximum fragrance.
14. Season the entire dish generously with salt and pepper, adjusting to your personal taste preference. Keep in mind that the tuna and potatoes will absorb the seasoning as they cook.
15. Cover the baking dish tightly. If your dish doesn’t have a lid, use aluminum foil, crimping the edges to create a tight seal. This will help to trap moisture and ensure even cooking.
16. Bake in the preheated oven until the potatoes are fork-tender. This usually takes around 45-60 minutes, but may vary depending on your oven and the thickness of the potato slices. Check for doneness by inserting a fork into a potato slice; it should slide in easily.
17. Once the potatoes are tender, remove the baking dish from the oven and let it rest for 10 minutes before serving. This allows the flavors to meld together and the dish to cool slightly.

Expert Tips & Tricks

• Tuna Variety: While tuna steaks are ideal, you can also use canned tuna in a pinch. Drain the tuna well and add it during the last 20 minutes of baking to prevent it from drying out.
• Slow Cooker Adaptation: For a hands-off approach, this recipe works beautifully in a slow cooker. Cook on low heat for 6 hours or on high heat for 4 hours. Add a little extra water if needed to keep the tuna moist.
• Thick Tuna Steaks: If you’re using thick tuna steaks, increase the cooking time and add more water as needed to ensure the tuna cooks through without drying out.
• Wine Infusion: For a deeper flavor, add a splash of white or red wine to the braising liquid before baking.
• Pre-Soaking Potatoes: If you have time, soak the sliced potatoes in cold water for 30 minutes before layering them. This helps to remove excess starch, resulting in a creamier texture.
• Flavor Boost: A pinch of red pepper flakes adds a subtle kick of heat to the dish.

Serving & Storage Suggestions

Serve the Maltese Baked Tuna hot, directly from the baking dish. Garnish with extra fresh parsley or mint for a pop of color. It pairs perfectly with a simple green salad and crusty bread for soaking up the flavorful juices.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. They can be enjoyed cold or reheated in the microwave or oven. To reheat in the oven, cover the dish with foil to prevent it from drying out. This dish is also surprisingly good served at room temperature for lunch.
