How to Make Mahi Mahi in Oven
Quick Overview

Total Time: 20 minutes Prep Time: 10 minutes
Cook Time: 10-12 minutes Serves: 4 people
Key Ingredients for Mahi Mahi
For the Fish:
- 4 mahi mahi fillets (6 oz each)
- 2 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon paprika
For the Lemon Herb Topping:
- 2 lemons (juiced and zested)
- 2 tablespoons fresh parsley (chopped)
- 1 tablespoon fresh dill (chopped)
- 2 cloves garlic (minced)
- 2 tablespoons butter (melted)
Step-by-Step Instructions
Step 1: Preheat Your Oven
Set your oven to 400°F (200°C). This high temperature is crucial for achieving a beautiful golden crust while keeping the inside tender and flaky.
Step 2: Prepare the Baking Dish
Line a baking dish with parchment paper or lightly grease it with cooking spray. This prevents sticking and makes cleanup incredibly easy.
Step 3: Season the Fish
Pat the mahi mahi fillets completely dry with paper towels. This step is essential for proper seasoning and browning. Brush both sides with olive oil, then season generously with salt, pepper, garlic powder, and paprika.
Step 4: Create the Herb Mixture
In a small bowl, combine lemon juice, lemon zest, chopped parsley, dill, minced garlic, and melted butter. Mix well until all ingredients are evenly distributed.
Step 5: Assemble the Dish
Place the seasoned fillets in the prepared baking dish. Spoon the herb mixture evenly over each fillet, making sure to coat the entire surface.
Step 6: Bake to Perfection
Bake for 10-12 minutes, or until the fish flakes easily with a fork and reaches an internal temperature of 145°F (63°C). The exact time depends on the thickness of your fillets.
Step 7: Rest and Serve
Let the fish rest for 2-3 minutes before serving. This allows the juices to redistribute, ensuring maximum flavor and moisture.

Top Tips for Perfecting Mahi Mahi
Choose the Right Fish
Look for fillets that are firm, translucent, and have a mild ocean smell. Avoid fish with a strong fishy odor or mushy texture. Fresh mahi mahi should have a pinkish hue and firm flesh.
Don’t Overcook
Mahi mahi cooks quickly, so watch it carefully. Overcooked fish becomes dry and tough. The fish is done when it flakes easily and is opaque throughout.
Temperature Matters
Use a meat thermometer to ensure accuracy. The internal temperature should reach 145°F (63°C) for food safety while maintaining perfect texture.
Ingredient Substitutions
- No fresh herbs? Use 1 teaspoon dried herbs instead
- Out of paprika? Try cumin or chili powder
- No lemons? Lime juice works beautifully
- Olive oil substitute: Avocado oil or melted butter
Common Mistakes to Avoid
Never skip patting the fish dry – moisture prevents proper browning. Don’t overcrowd the baking dish, as this creates steam instead of roasting. Avoid moving the fish too much during cooking.
Storing and Reheating Tips
Proper Storage Methods
Store leftover mahi mahi in the refrigerator for up to 3 days in an airtight container. For best quality, wrap each fillet individually in plastic wrap before placing in the container.
Freezing Guidelines
Cooked mahi mahi can be frozen for up to 3 months. Wrap tightly in freezer-safe packaging and label with the date. Thaw overnight in the refrigerator before reheating.
Reheating Instructions
The best way to reheat mahi mahi is in a 350°F oven for 8-10 minutes. This gentle heat prevents the fish from drying out. Alternatively, use the microwave on 50% power for 1-2 minutes, checking frequently.
Food Safety Tips
Never leave cooked fish at room temperature for more than 2 hours. When reheating, ensure the internal temperature reaches 165°F (74°C) for food safety.
