Cooking Instructions

Prep Tuna: Begin by preparing your fresh tuna steaks. If they are frozen, ensure they are fully thawed in the refrigerator. Once ready, pat the tuna dry with paper towels.
Make Spice Rub: In a small bowl, combine salt, black pepper, cayenne pepper, garlic powder, paprika, dried thyme, and celery salt. Mix these spices thoroughly to create your seasoning blend.
Season Tuna: Rub the spice mixture evenly over each side of the tuna steaks. Let the seasoned tuna sit for a few minutes to absorb the flavors while you heat your skillet.
Heat Skillet: Heat a large cast-iron skillet over medium-high heat and add oil once hot. Ensure the skillet is very hot for perfect searing.
Sear Tuna: Transfer the seasoned tuna steaks into the skillet and sear each side for about 1-2 minutes for a rare finish, adjusting the time as necessary.
Make Remoulade: In a bowl, combine mayonnaise, Creole mustard, horseradish, lemon juice, Worcestershire sauce, ketchup, and hot sauce. Mix and adjust seasoning to your preference.
Slice & Serve: Slice the tuna steaks into ¼-inch thick pieces, drizzle remoulade over the top, and serve alongside your favorite sides.
