Ingredients for recipe:
Before we get into the step by step instructions, a few notes about the ingredients:
Fish: the recipe calls for mahi but you can use cod, haddock, halibut or your favorite white fish. Just monitor cook time to ensure your fish is cooked through.
Garlic: fresh cloves are always best.
Fresh herbs: fresh dill is a slam-dunk choice for this dish. Substitute basil, chives or flat-leaf parsley.
Asparagus: make it a one-pan dinner by adding fresh asparagus spears or thin green beans to your baking sheet.

How to Make Baked Mahi Fish
1. Prep fish
Preheat oven to 400 degrees. Place fish fillets on a baking sheet covered with foil. Add trimmed asparagus to the pan, if using.
2. Make Garlic Butter Dill Sauce
Melt butter and sliced garlic in microwave. Then add Dijon, lemon juice, salt, pepper and fresh dill and stir. Pour butter herb sauce over the mahi and asparagus.
3. Bake and Serve
Bake for 10-12 minutes, until fish is cooked through and flaky (about 140). Serve with additional fresh dill and lemon wedges, for garnish.
Does mahi taste fishy?
Mahi Mahi is a mild, firm white fish. It's mild enough to be a great option for kids or anyone who's not sure they like fish. The flavorful sauce on this easy baked fish recipe makes it a winner for the whole family.
Side dishes for baked mahi:
Duchess Potato Casserole would be an ideal side to soak up all that delicious garlic Dijon sauce, along with the roasted asparagus. If you're looking for a fresh side, try Tomato Cucumber Salad.
How to store and reheat baked fish?
To store, transfer baked mahi to an airtight container and keep in the refrigerator for up to 2-3 days. To reheat, warm gently in a skillet with a tablespoon of stock or water, or a pat of butter, until just heated through.

I loved the dill so much! I think I overcooked it, but it was still really good. Can't wait to make again!
