Step‑by‑Step Instructions for Blackened Tuna Steak Recipe Step 1: Prep the Tuna Begin by thawing your tuna steaks if they are frozen. Gently pat them dry with a paper towel to remove any excess moisture, ensuring a good sear. This essential step will help achieve that irresistible, blackened crust when you cook. Set the prepared steaks aside while you mix your spice rub. Step 2: Make the Spice Rub In a mixing bowl, combine salt, black pepper, cayenne pepper, garlic powder, paprika, dried thyme, and celery salt. Use a whisk or fork to mix the spices thoroughly, ensuring they are evenly distributed. This flavorful blend will coat your tuna steaks generously, enhancing the dish’s bold taste that makes the Blackened Tuna Steak Recipe stand out. Step 3: Apply the Spice Rub Take your drained tuna steaks and liberally sprinkle the spice mixture over both sides, pressing it gently into the fish. Ensure each steak is well-coated for maximum flavor and that classic blackened appearance. The spices should form a beautiful crust as they cook—this is crucial for the ultimate blackened tuna experience! Step 4: Heat the Skillet Heat a cast-iron skillet over medium to medium-high heat until it is shimmering and hot—this typically takes about 3-5 minutes. Once the skillet is ready, add cooking oil, swishing it around to coat the surface evenly. The right temperature is key to achieving that perfect sear, so don’t rush this step! Step 5: Sear the Tuna Carefully place the seasoned tuna steaks into the hot skillet. Sear them for about 1 minute on each side for a rare finish; adjust the cooking time to 3-5 minutes per side if you prefer medium or well-done. Watch for the exterior to become dark and charred, while the center should remain tender and juicy, characteristic of a delicious blackened tuna steak. Step 6: Prepare the Cajun Remoulade While the tuna is cooking, prepare the zesty remoulade by combining mayonnaise, mustard, horseradish, lemon juice, Worcestershire sauce, ketchup, hot sauce, paprika, black pepper, sugar, shallots, celery, fresh parsley, and scallion in a mixing bowl. Stir well until all ingredients are blended smoothly, allowing the flavors to meld together perfectly. Step 7: Rest and Serve Once the tuna steaks are cooked to your preference, remove them from the skillet and let them rest for a minute to lock in juices. Slice the steaks into ¼-inch pieces and arrange them on a serving platter. Drizzle your delicious Cajun remoulade over the top, and you’re all set to savor this fantastic Blackened Tuna Steak Recipe!
