Ingredient Breakdown
Every element plays a role in creating flavor and texture.
1. Mahi Mahi Filets
Mahi mahi is a firm, white fish with a slightly sweet flavor. It holds up well to baking and pairs beautifully with citrus. It’s lean, protein-packed, and mild enough to please even non-seafood lovers.
2. Olive Oil (for drizzle)
Adds moisture and helps the fish bake evenly while giving it a delicate richness. Use a high-quality extra virgin olive oil for the best results.
3. Old Bay Seasoning
A classic seafood seasoning made with paprika, celery salt, and spices. It adds depth and a subtle kick without overpowering the fish.
4. Butter (2 tbsp, softened)
Forms the base of the lime butter. Butter adds richness and helps carry the lime flavor across the fish.
5. Lime Juice + Zest (of 1 lime)
Brightens the dish with tangy citrus notes. Zest is especially powerful for adding fragrance and flavor without extra acidity.
6. Pinch of Salt
Balances the flavors and enhances the citrus and spice.

Mahi Mahi with Lime Butter
Servings: 4 | Prep Time: 5 minutes | Cook Time: 12–15 minutes | Total Time: 20 minutes
Ingredients:
4 mahi mahi filets
1–2 tbsp olive oil (for drizzle)
Old Bay seasoning, generous sprinkle for each filet
2 tbsp butter, softened
Zest + juice of 1 lime
Pinch of salt
Directions:
Preheat oven to 400°F. Line a sheet pan with parchment paper.

Bake for 12–15 minutes, or until fish flakes easily with a fork (internal temp 137–145°F).
While fish bakes, mash softened butter with lime juice, zest, and a pinch of salt.
When mahi mahi comes out of the oven, brush lime butter over both sides of each filet.
Serve hot with extra lime wedges, if desired.
Tips for Success
Pat the Fish Dry: Helps the oil and seasoning stick, and prevents soggy texture.
Don’t Overcook: Mahi mahi cooks quickly. Pull it from the oven as soon as it flakes easily.
Room Temperature Butter: Make sure butter is softened for easy mixing with lime.
Customize Seasoning: Swap Old Bay for Cajun seasoning, lemon pepper, or garlic herb blends.
Garnish with Fresh Herbs: A sprinkle of cilantro or parsley makes the dish pop.
Variations
Grilled Mahi Mahi with Lime Butter: Grill filets over medium heat for a smoky version.
Spicy Lime Butter: Add a pinch of cayenne or chili flakes to the butter.

Storage & Reheating
Refrigerate: Store leftovers in an airtight container for up to 3 days.
