Ingredients

The Mahi Mahi & Marinade:

  • 4 Mahi Mahi Filets about 2 pounds
  • 2 Limes juiced
  • 3 Garlic Cloves Minced
  • 1 jalapeño seeded and chopped
  • cup Cilantro roughly chopped
  • 1 tsp Salt
  • 2 tbsp Olive Oil

The Cilantro Lime Crema:

  • 3 tbsp Sour Cream
  • 3 tbsp Mayonnaise
  • ¼ cup Green Onions Chopped
  • ¼ cup Chopped Cilantro
  • Zest from ½ lime
  • Juice from ½ lime
  • 1 tsp Salt

For Serving:

  • 8-10 Corn or flour tortillas
  • 2 cups Shredded cabbage or slaw mix
  • Fresh lime wedges

Instructions

  • Mise en Place: Gather your fresh limes, cilantro, garlic, jalapeño, extra virgin olive oil, and salt before you begin.
  • The Marinade: Pulse the aromatics and oil in a food processor until you achieve a vibrant green consistency.
  • The Soak: Place the Mahi Mahi in a Ziploc bag with the marinade and refrigerate for one hour to infuse the flavor.
  • Sauce Prep: Whisk the sour cream, mayo, onions, cilantro, lime, and salt together then chill until serving.
  • BGE Setup: Preheat your Big Green Egg to 450°F using the direct heat method for a clean, professional sear.
  • The Sear: Grill the filets for four minutes per side with the dome closed to lock in moisture and flavor.
  • The Pull: Remove the fish once the internal temperature hits 130°F on an instant-read thermometer for maximum juiciness.
  • The Rest: Let the Mahi Mahi sit for five minutes to ensure the juices redistribute through the meat before slicing.
  • The Build: Slice the fish and serve on warm tortillas topped with crisp slaw and a generous drizzle of Cilantro Lime Crema.
