Blackened seasoning is my go-to seasoning for pan frying most types of fish, especially salmon, and it also works really well on ahi tuna. This dish takes almost no time to make, since the tuna is very quickly seared so that the center stays medium-rare. Well-done tuna is, frankly, a travesty - just make sure your tuna is fresh and/or (even better) sushi grade.
Ingredients: (2 servings)
Two 4-5 oz. Ahi tuna steaks
Blackened seasoning (or use whatever seasoning blend you like, including just salt & pepper)
4 tbsp. light mayonnaise
1-2 tsp. wasabi paste (according to your taste)
1 tsp. honey
1 scallion, minced
1-2 tbsp. water
1. Season the tuna steaks on all sides with the blackened seasoning or just salt & pepper.
2. Mix together the mayonnaise, wasabi paste, honey, & minced scallions. Thin out the sauce by stirring in 1-2 tbsp. of water. Set aside.
3. In a saute pan, heat 1 tbsp. of vegetable or olive oil over high heat and add the tuna steaks. Sear about 1-2 minutes per side (should be medium to medium rare in the middle) and remove immediately to a chopping board.
4. Slice the tuna steaks into 1/4" slices and fan each out on a serving plate. Serve with wasabi-honey mayonnaise sauce, lemon wedges and a salad on the side.
