Easy Mahi-Mahi Carpaccio Recipe with Capers and Lemon

If you are looking for an elegant, restaurant-quality seafood appetizer that looks sophisticated but costs a fraction of the price of dining out, this easy mahi-mahi carpaccio recipe is an absolute must-try. Made with thinly sliced, fresh white fish, it is a truly amazing and refreshing dish that balances the buttery texture of raw mahi-mahi with the bold, briny punch of tangy capers, crisp shaved onions, and a drizzle of rich extra virgin olive oil. Perfect for warm weather entertaining or a quick date night at home, this affordable gourmet recipe comes together in just 10 minutes with minimal prep and simple, budget-friendly ingredients. It proves you don’t need to spend a fortune or have advanced chef skills to serve a stunning, coastal-inspired centerpiece that will completely wow your guests.

I use a premium bag of frozen mahi-mahi portions (like the wild-caught fillets found at Costco), you can easily shave the fish into paper-thin, translucent slices using your sharp Japanese knife while the protein is still firm and partially frozen. One of the best things about making this gourmet appetizer with a bag of frozen individual fillets is the lack of food waste. For this recipe, you only need 2 pieces of mahi-mahi to create a gorgeous, full platter that easily serves a crowd.
Because each fillet is individually vacuum-sealed, you can simply pull out exactly what you need for date night or a dinner party, and keep the rest safely tucked away in your freezer for future weeknight meals. It is a fantastic, cost-effective way to enjoy high-end seafood without having to purchase a massive, expensive fresh loin all at once!

Ingredients
2 Portions Frozen Mahi-Mahi: Wild-caught fillets (such as Costco portions), sliced paper-thin with your sharp Japanese knife while still partially frozen.
1/4 Small White Onion: Shaved into razor-thin slivers.
2 tbsp Nonpareil Capers: Drained and scattered evenly across the platter.
2 tbsp Extra Virgin Olive Oil: Premium quality, for a rich, silky finish.
1/2 Fresh Lemon: Juiced and zested over the fish just before serving.
Sea Salt Flakes & Freshly Cracked Black Pepper: To taste.
Directions
- Slice the Fish Paper-Thin
- Lightly sprinkle the fish with sea salt flakes and freshly cracked black pepper to taste. Squeeze just a touch of fresh lemon juice over the top, but be careful not to use too much, as you want the bright citrus to enhance, not kill, the natural, delicate flavor of the fresh fish.
- Scatter your thin white onions evenly across the platter. Drizzle a premium extra virgin olive oil over the fish and onions in a slow, zigzag motion to coat everything with a rich, silky finish.
- Scatter the drained capers across the top to add a bright, briny pop.
- Optional: For a final, vibrant touch, gently scatter a few fresh arugula leaves over the center of the plate for color and texture. Serve immediately while chilled.
