Ingredients
  

For the Zesty Mahi Mahi
  • 2 fillets Mahi Mahi approx. 6 oz (170g) each, skin removed if desired, patted dry
  • 2 tbsp Olive oil
  • 1/2 lemon Lemon thinly sliced
  • 1/2 lemon Lemon juiced (about 1.5 tbsp)
  • 3 cloves Garlic minced
  • 2 tbsp Fresh parsley finely chopped
  • 1 tsp Dried oregano
  • 1/2 tsp Salt
  • 1/4 tsp Black pepper
  • 1/2 tsp Smoked paprika optional, for color and depth
For the Roasted Vegetables
  • 1 bunch Asparagus approx. 1 lb (450g), tough ends trimmed
  • 1 cup Cherry tomatoes halved
  • 1 tbsp Olive oil
  • 1/4 tsp Salt
  • 1/8 tsp Black pepper

Equipment

  • Large baking sheet
  • Parchment Paper
  • Small Mixing Bowl
  • Knife
  • Cutting Board

Method
 

Preparation
  1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
Prepare Vegetables
  1. On one side of the prepared baking sheet, arrange the trimmed asparagus and halved cherry tomatoes. Drizzle with 1 tablespoon of olive oil, season with 1/4 teaspoon salt and 1/8 teaspoon black pepper. Toss gently to coat.
Season Mahi Mahi
  1. In a small mixing bowl, combine 2 tablespoons olive oil, fresh lemon juice (from 1/2 lemon), minced garlic, chopped fresh parsley, dried oregano, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and smoked paprika (if using). Mix well to form a thick marinade.
  2. Place the patted-dry mahi mahi fillets on the empty side of the baking sheet, away from the vegetables. Spoon the prepared seasoning mixture evenly over both sides of each mahi mahi fillet. Top each fillet with a few thin lemon slices.
Bake
  1. Transfer the baking sheet to the preheated oven. Bake for 15-20 minutes, or until the mahi mahi is opaque and flakes easily with a fork, and the vegetables are tender-crisp. The cooking time will depend on the thickness of your fillets.
Serve
  1. Carefully remove the baking sheet from the oven. Serve the Zesty Garlic Herb Baked Mahi Mahi immediately with the roasted asparagus and cherry tomatoes. A sprinkle of fresh parsley over the top for garnish is optional.

Notes

Mahi mahi cooks quickly, so be careful not to overcook it, as it can become dry. The internal temperature should reach 145°F (63°C). You can substitute other quick-cooking vegetables like broccoli florets or bell pepper strips for the asparagus and tomatoes. Adjust roasting time if necessary. Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently to prevent drying out.

Pro Tips for Making This Baked Mahi Mahi Dinner

When I’m making a dish like this Baked Mahi Mahi Dinner, I always rely on a few little tricks I’ve picked up over the years to ensure it turns out perfectly every time. It’s all about enhancing those natural flavors and making the cooking process as enjoyable as possible!

My Secret Trick: I always line my baking sheet with parchment paper! It makes for the easiest cleanup, and the fish and vegetables slide right off without sticking, preserving their beautiful presentation and ensuring a perfectly tender Baked Mahi Mahi Dinner.

First, don’t overcrowd your baking sheet. Giving the fish and vegetables enough space allows them to roast rather than steam, leading to beautifully caramelized edges and perfectly cooked ingredients. If your sheet is too full, use two!

Always use fresh lemon juice and zest. The bottled stuff just doesn’t have the same vibrant punch, and that bright, zesty note is absolutely crucial for elevating the delicate flavors of the mahi-mahi and making this a truly memorable Baked Mahi Mahi Dinner.

Finally, keep an eye on your cooking time. Mahi-mahi cooks relatively quickly, and overcooked fish can become dry. I always check for flakiness with a fork around the 18-minute mark to ensure it’s perfectly tender and juicy.

Fun Variations for Baked Mahi Mahi Dinner

One of the things I adore most about home cooking is the freedom to play and adapt! This Baked Mahi Mahi Dinner is wonderfully versatile, and a few simple swaps can completely transform its character. It’s like having a blank canvas for your culinary creativity!

Spice It Up

For those who love a little heat, consider adding a pinch of red pepper flakes to the lemon-garlic butter mixture. My sister always asks me to add a touch of cayenne for an extra kick that beautifully complements the lemon. It turns a simple Baked Mahi Mahi Dinner into something with a bit more zing!

Herb Garden Freshness

While parsley and oregano are lovely, feel free to experiment with other fresh herbs. Dill adds a beautiful, subtle anise flavor that pairs wonderfully with fish, or a sprinkle of fresh thyme can bring an earthy depth. It’s a fantastic way to use what’s thriving in your garden!

Seasonal Veggie Swaps

Asparagus and cherry tomatoes are delightful, but this dish is incredibly forgiving if you want to swap in other seasonal vegetables. Thinly sliced bell peppers, zucchini, or even broccoli florets would bake beautifully alongside the fish, absorbing all those lovely lemon-garlic flavors. A friend loves when I include colorful bell peppers for a vibrant touch to her Baked Mahi Mahi Dinner.

What to Serve With Baked Mahi Mahi Dinner

When I prepare this delightful Baked Mahi Mahi Dinner, I often think about how to create a complete meal that feels both comforting and elegant. It’s about complementing those bright, fresh flavors with something equally satisfying.

I love serving this Baked Mahi Mahi Dinner with a side of fluffy quinoa or a light couscous. Their mild flavors and textures are perfect for soaking up the zesty lemon-garlic juices from the fish and vegetables. My mom always pairs it with a simple green salad dressed with a vinaigrette to keep things fresh and light. For a quick serving idea, a scoop of brown rice is always a welcome addition to the plate. Sometimes, if I’m feeling fancy, I’ll even add a sprinkle of toasted slivered almonds over the fish for a little extra crunch.

How to Store Baked Mahi Mahi Dinner

After all the love that goes into making this Baked Mahi Mahi Dinner, you’ll want to ensure any leftovers are kept just as delicious! Proper storage means you can enjoy those wonderful flavors for another meal, just like magic.

For refrigerator storage, allow the cooked Baked Mahi Mahi Dinner to cool completely to room temperature. Then, transfer the fish and vegetables to an airtight container. It will keep beautifully in the fridge for up to 2-3 days. My personal tip? I like storing the fish separately from the vegetables if possible, as it helps maintain its texture.

If you’re looking to freeze leftovers, wrap individual portions of the cooked mahi-mahi tightly in plastic wrap, then place them in a freezer-safe bag or container. This will help prevent freezer burn and keep the fish fresh for up to a month. When reheating, gently warm in the oven or microwave until heated through, being careful not to overcook.

Nutritional Benefits

This Baked Mahi Mahi Dinner isn’t just delicious; it’s also wonderfully nourishing, proving that wholesome eating can be incredibly flavorful! Mahi Mahi is an excellent source of lean protein, supporting muscle health and keeping you feeling full. Combined with the vibrant array of vitamins and antioxidants from the fresh lemon, asparagus, and cherry tomatoes, it’s a treat that’s both satisfying and contributes to a balanced plate.
