Baked Mahi-Mahi with Garlic-Herb Butter


This baked mahi-mahi is cooked on top of lemon slices that impart their flavor through the fish, which is complemented by the buttery garlic and herb sauce baked on top. We like the meatiness of mahi-mahi, but this simple technique works well with other fish too, like salmon, cod or halibut.

Active Time:
10 mins
Total Time:
40 mins


  • 1 medium lemon

  • 4 (5 ounce) skinless mahi-mahi fillets

  • ½ teaspoon salt

  • 2 tablespoons unsalted butter

  • 1 teaspoon fresh thyme leaves, plus more for garnish

  • 1 medium clove garlic, grated

  • ½ teaspoon coarsely ground pepper

  • ¼ teaspoon smoked paprika


  1. Preheat oven to 400°F. Line a large rimmed baking sheet with parchment paper. Grate lemon to yield 1 teaspoon zest; place the zest in a small microwaveable bowl. Cut 4 (1/4-inch-thick) slices from the grated lemon; transfer the slices to the prepared baking sheet. Save remaining lemon for another use.

  2. Place 1 mahi-mahi fillet on top of each lemon slice. Sprinkle evenly with salt.

  3. Place butter, thyme, garlic, pepper and paprika in the bowl with the lemon zest. Microwave on High until the butter is melted and the spices are fragrant, about 30 seconds. Stir to combine. Spoon and brush evenly over the mahi-mahi fillets.

  4. Bake until the fish flakes easily with a fork, about 20 minutes. Garnish with additional thyme, if desired.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
