This is one of my favorite weeknight dinners because it comes together in just 35 minutes and tastes like something from a fancy restaurant. Mahi mahi is such a wonderful lean fish that's packed with protein and omega 3 fatty acids, making it as good for you as it is delicious. The roasted radishes add this lovely peppery sweetness that you wouldn't expect, and the silky lemon butter sauce ties everything together beautifully. Best of all, it requires minimal prep and uses simple ingredients you probably already have on hand. Trust me, this one is a keeper.

Preheat oven to 425°F. Pat mahi mahi fillets dry with paper towels and season both sides with salt, pepper, and thyme.
Tip: Drying the fish ensures better browning and a more delicate texture.

Toss halved radishes with 2 tablespoons olive oil, minced garlic, salt, and pepper on a large baking sheet. Spread in a single layer and roast for 12-15 minutes until golden and tender.
Tip: Stir radishes halfway through cooking for even caramelization.

Push roasted radishes to the sides of the baking sheet. Place mahi mahi fillets in the center and drizzle with remaining 2 tablespoons olive oil.
Tip: Ensure fillets have space around them for proper heat circulation.

Return baking sheet to oven and roast for 6-8 minutes until mahi mahi is opaque and flakes easily with a fork.
Tip: Do not overcook as mahi mahi is delicate and can become dry quickly.

While fish cooks, melt butter in a small saucepan over low heat. Add lemon juice and lemon zest, whisking gently for 1-2 minutes until combined.
Tip: Keep heat low to prevent butter from browning.

Transfer mahi mahi and roasted radishes to serving plates. Drizzle warm lemon butter sauce over the fish and radishes.
