Instructions: Heat oven to 400 degrees. Combine paprika, oregano, garlic powder, onion powder, salt, cumin, pepper, and cayenne pepper on a plate. Rub butter over tuna steaks. Press tuna steaks into spice mixture; gently rub spices onto fish.

Heat a large heavy ovenproof skillet (cast-iron works great) over high heat for 2 minutes or until skillet smokes. Cook tuna steaks 1 minute on each side. They will make some smoke, this is normal. Transfer skillet to oven and roast fish 5 minutes for medium-rare doneness.

This recipe yields 4 servings.

Comments: If you dont have an ovenproof skillet, transfer seared fish to a baking sheet to finish cooking.

Description: "Tuna, a naturally lean fish, is tender and juicy when cooked rare or medium-rare. In this dish, searing dry heat chars a spice crust onto the fish."
