Honey Mustard Grilled Mahi Mahi
If you’re looking for a flavorful and healthy seafood dish that feels restaurant-worthy yet easy enough for a weeknight, Honey Mustard Grilled Mahi Mahi is the perfect choice.
Mahi mahi, sometimes called dorado or dolphinfish, is a lean, firm-textured white fish with a mildly sweet flavor. It’s hearty enough to handle the grill without falling apart, making it ideal for marinades and bold seasonings. Pairing it with a honey mustard glaze adds the perfect combination of tangy, sweet, and savory notes that complement the natural richness of the fish.
This recipe uses a quick marinade of honey, Dijon mustard, garlic, and lemon to infuse the fish with flavor before grilling. The result is a golden, slightly caramelized glaze coating tender, flaky mahi mahi fillets. It’s nutritious, simple to prepare, and pairs beautifully with rice, grilled vegetables, or a crisp salad.
Ingredients
For the Fish:
- 4 mahi mahi fillets (about 6 oz each)
- 1 tablespoon olive oil (for brushing grill)
- Salt and black pepper to taste
For the Honey Mustard Marinade:
- 3 tablespoons Dijon mustard
- 2 tablespoons honey
- 1 tablespoon whole-grain mustard (optional, for texture)
- 2 garlic cloves, minced
- Juice of 1 lemon
- Zest of ½ lemon
- 2 tablespoons olive oil
- ½ teaspoon paprika
- ½ teaspoon cayenne pepper (optional, for a little heat)
- Salt and pepper to taste

How to Make Honey Mustard Grilled Mahi Mahi
Step 1: Prepare the Marinade
In a small bowl, whisk together Dijon mustard, honey, whole-grain mustard (if using), garlic, lemon juice, lemon zest, olive oil, paprika, cayenne pepper, salt, and black pepper.
Taste and adjust balance—add more honey if you prefer sweeter, or more mustard for tang.
Step 2: Marinate the Fish
Pat mahi mahi fillets dry with a paper towel.
Place fillets in a shallow dish or resealable bag.
Pour half of the honey mustard marinade over the fish, making sure it coats evenly. Reserve the other half for basting and serving.
Cover and refrigerate for 20–30 minutes. Avoid marinating too long, as the lemon juice can start to “cook” the fish.
Step 3: Preheat the Grill
Heat the grill (gas or charcoal) to medium-high heat, about 375–400°F.
Lightly oil the grill grates to prevent sticking.
Step 4: Grill the Mahi Mahi
Remove the fish from the marinade, letting excess drip off.
Place fillets on the hot grill. Cook for 3–4 minutes per side, depending on thickness.
Baste with reserved marinade during the last minute of cooking for extra flavor.
The fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F.
Step 5: Serve
Transfer the grilled mahi mahi to a serving platter.
Drizzle with remaining honey mustard sauce.
Garnish with chopped parsley and serve with lemon wedges.

FAQs
- Can I use bottled honey mustard sauce instead of making the marinade from scratch?
Yes, but homemade honey mustard has fresher, more balanced flavors. Store-bought sauces can be overly sweet or processed.
- How do I know when mahi mahi is done cooking?
Mahi mahi should be opaque and flake easily with a fork. For accuracy, use a thermometer—the fish is fully cooked at 145°F.
- Can I bake the fish instead of grilling?
Absolutely. Bake at 400°F for 12–15 minutes, brushing with honey mustard sauce halfway through for a caramelized finish.
- How long should I marinate mahi mahi?
20–30 minutes is ideal. Any longer and the lemon juice can break down the fish and change its texture.
- What wine pairs best with Honey Mustard Grilled Mahi Mahi?
A crisp white wine like Sauvignon Blanc, Pinot Grigio, or Chardonnay pairs wonderfully with the tangy-sweet glaze.If you’re looking for a flavorful and healthy seafood dish that feels restaurant-worthy yet easy enough for a weeknight, Honey Mustard Grilled Mahi Mahi is the perfect choice.
