Gochujang Paste
Gochujang is a savory, sweet, and spicy fermented Korean condiment made from red chili powder, glutinous rice, fermented soybeans, and salt. Its complex flavor profile adds incredible depth and a gentle heat to any dish. Traditionally used in Korean classics like bibimbap and tteokbokki, gochujang is now loved worldwide for its versatility. It pairs especially well with grilled proteins, lending them a glossy finish and irresistible umami punch.

Mahi-Mahi
Mahi-Mahi, also known as dolphinfish (not related to the dolphin mammal!), is prized for its firm, flaky texture and mild, slightly sweet flavor. It holds up beautifully to grilling, making it a perfect canvas for bold marinades like soy-gochujang. Rich in lean protein and low in fat, Mahi-Mahi is also a great source of vitamins B3, B6, and B12, along with selenium and potassium.

Recipe Origin | GRILLED MAHI-MAHI W/ SOY-GOCHUJANG SAUCE
This recipe was inspired by a spontaneous backyard grilling session where I wanted something beyond the usual barbecue flavors. I had a craving for that distinctive kick you get from Korean dishes, so I whipped up a quick marinade featuring gochujang, soy sauce, and a little honey for balance. The Mahi-Mahi turned out so tender and flavorful that it instantly became a requested favorite for our family dinners! Now, whenever we’re looking for a light yet bold meal that feels special without tons of effort, this grilled fish is our go-to.

Tips, Serving Suggestions, and Storage Advice
Use Fresh Fish: Fresh Mahi-Mahi (or Halibut) will give you the best flavor and texture.
Adjust the Spice: Add more gochujang if you like it spicier, or a little extra honey if you prefer it milder.
Marinate Carefully: Don't marinate the fish for more than an hour — the acids can start to "cook" the fish and change its texture.
Non-Stick Grill Tip: Lightly oil your grill grates or pan to prevent the fish from sticking.
Alternative Fish Choices: This marinade also works great with cod, haddock, or even salmon.

Serve with Sides: Pair the grilled fish with jasmine rice, stir-fried veggies, or a fresh cucumber salad.
Indoor Grilling Option: Use a grill pan on the stovetop if the weather isn’t cooperating.
Leftovers: Store leftover cooked fish in an airtight container in the fridge for up to two days.
Reheat Gently: Reheat leftover fish over low heat to avoid drying it out.
Use Leftover Marinade: Simmer any unused marinade separately to serve as a drizzling sauce (never reuse raw marinade without cooking it first!).

FAQ Section
Q: Can I substitute another fish for Mahi-Mahi?
A: Absolutely! Halibut, cod, or haddock are great alternatives that hold up well to grilling and the bold marinade.
Q: How spicy is the sauce?
A: The heat level is mild to medium. You can adjust it by adding more or less gochujang based on your spice preference.

A: Simply add them to a dry skillet over medium heat for a few minutes, shaking often, until golden and fragrant.
Q: Can I make this ahead of time?
A: You can marinate the fish up to 8 hours ahead, but grilling should be done right before serving for best texture.

A: It’s best enjoyed fresh. However, you can freeze raw marinated fillets for up to 1 month and grill them after thawing.
Q: What can I serve with this dish?
A: Great options include jasmine rice, stir-fried vegetables, or a light cucumber and avocado salad.
Q: How do I know when the fish is cooked?
A: The fish should be opaque and flake easily when tested with a fork.
Q: Is gochujang gluten-free?
A: Some brands are, but check the label to be sure, as traditional gochujang may contain wheat.
