Recipe Ingredients for Grilled Fish with Lemon and Capers

Each ingredient in this recipe plays a significant role in creating a delicious and harmonious flavor profile. The combination of fresh Mahi Mahi, bright lemon, and savory capers comes together beautifully, making it a perfect dish for any occasion.
- Mahi Mahi filets – 4 pieces: A firm and flavorful fish that holds up well to grilling.
- Oil – 1 tablespoon: Used for oiling the grill grates, ensuring the fish doesn’t stick.
- Lemon – Pieces for serving: Adds a fresh, zesty flavor that complements the fish beautifully.
Directions for Grilled Fish with Lemon and Capers

Cooking Grilled Fish with Lemon and Capers is a breeze and can be incredibly satisfying. Here’s how to do it step by step:
- Start by thawing the Mahi Mahi if it’s frozen. Ideally, you should do this overnight in the fridge. But if you’re pressed for time, you can submerge it in cold water.
- Once thawed, drain the fish in a colander. To ensure it’s ready for grilling, place the filets between layers of paper towels and press down gently to remove excess moisture.
- Next, zest the lemon and squeeze out the juice. If the zest is in large pieces, consider chopping it up to distribute the flavor evenly.
- In a bowl, combine the lemon zest, lemon juice, capers (chopped), olive oil, garlic powder, onion powder, dried parsley, and black pepper. Whisk them together to create a flavorful marinade.
- Place the fish filets in a small Ziploc bag and pour the marinade over them. Seal the bag and let the fish marinate in the fridge for one to two hours. Be cautious not to exceed this time, as the lemon juice can start to “cook” the fish.
- When you’re ready to grill, remove the fish from the marinade and drain it, catching the marinade for disposal later to avoid clogging your drain. Allow the fish to come to room temperature.
- Preheat your grill to high heat, spraying the grates with non-stick grilling spray or brushing them with oil.
- Once the grill is hot, lower the heat to medium-high and place the fish on the grates. To achieve beautiful criss-cross grill marks, lay the filets at a diagonal angle. Cook for approximately two to three minutes, until you see nice grill marks when lifting an edge.
- Rotate the fish on the same side in the opposite direction to create crosshatches and cook for another two to three minutes.
- Turn the fish over and grill for about two to three minutes on the other side. The fish is done when it feels firm yet not hard to the touch. I usually cook mine for about nine minutes total.
- Serve hot, garnished with additional lemon slices for squeezing at the table, if desired.
Things Worth Knowing
- Thawing Tip: If you’re short on time, thaw the fish in cold water rather than overnight. Just be sure to change the water periodically for even thawing.
- Marinating: For maximum flavor, don’t skip the marination step. Just a couple of hours can infuse the fish with a wonderful zing.
- Grill Safety: Always preheat your grill to ensure those gorgeous grill marks form and to prevent sticking.
- Doneness Check: Use a fork to gently flake the fish. If it flakes easily and is opaque all the way through, it’s done!
