Introduction
This Mediterranean-style Barramundi recipe highlights fresh, vibrant flavors with juicy tomatoes, briny olives, and fragrant basil. It’s a simple yet elegant dish perfect for a quick weeknight dinner or a special gathering.

Ingredients
- 4 5-oz Barramundi fillets (thawed if frozen)
- 1 tsp Sea salt
- 1/4 tsp Black pepper
- 2 tbsp Olive oil
- 2 tbsp Unsalted butter
- 1 large Red onion (sliced into thin half moons)
- 2 cloves Garlic (minced)
- 2 cups Cherry tomatoes
- 1 cup Olives (pitted; mix of black and green recommended)
- 1 tbsp Lemon juice (plus extra lemon wedges for serving)
- 1/2 cup Fresh basil (cut into ribbons; divided)
- 1/3 cup Feta cheese (diced or crumbled; optional)
Instructions
- Step 1: Pat the fish dry with paper towels and season both sides with sea salt and black pepper.
- Step 2: Heat olive oil in a large nonstick skillet over medium-high heat until shimmering. Add two fillets, skin-side down, and sear for 2-4 minutes until golden brown.
- Step 3: Flip the fillets and cook for 1-3 minutes more, until golden and the internal temperature reaches 135-140°F (57-60°C). Transfer to a plate, cover, and keep warm. Repeat with the remaining fillets.
- Step 4: Add butter to the same pan and melt. Add the sliced onions and cook for about 5 minutes until translucent and beginning to brown.
- Step 5: Stir in the minced garlic and cook for about 1 minute until fragrant.
- Step 6: Add cherry tomatoes, olives, lemon juice, and half of the basil ribbons. Cover and cook for 5-6 minutes until tomatoes soften and start to pucker.
- Step 7: Return the fish to the pan, spooning the tomato and olive mixture over the fillets. Serve topped with the remaining basil, feta cheese if using, and extra lemon wedges for squeezing.
Tips & Variations
- Use a mix of black and green olives for balanced briny flavor.
- To reduce cooking time, cut cherry tomatoes in half before cooking.
- For added heat, sprinkle with red pepper flakes when adding garlic.
- If feta isn’t available, try crumbled goat cheese or omit cheese altogether for a lighter dish.
- Serve with crusty bread or over a bed of couscous or quinoa for a complete meal.
Storage
Store leftover cooked fish in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat to avoid drying out the fish. The tomato and olive mixture can be reheated separately and spooned over the fish after warming.

FAQs
Can I use other types of fish instead of Barramundi?
Yes, firm white fish like cod, snapper, or sea bass work well with this recipe and provide similar texture and flavor absorption.
How do I know when the fish is done?
The fillets should be opaque and easily flake with a fork. Using a thermometer, an internal temperature of 135-140°F (57-60°C) ensures perfectly cooked fish without drying it out.

Instructions
- Prepare the fish: Pat the barramundi fillets dry thoroughly with paper towels. Season both sides evenly with sea salt and black pepper to enhance the flavor.
- Sear the fish: Heat olive oil in a large nonstick skillet over medium-high heat until it shimmers. Place two fish fillets skin-side down and sear them for 2-4 minutes until the surface is golden brown.
