Blackened tuna steak is coated in a bold Cajun-style spice blend with paprika, cayenne, garlic, and pepper, then quickly seared in a hot skillet. The outside forms a dark crust while the center stays tender and rare. A fast, high-protein dish packed with big flavor.
Rinse defrosted tuna under cold running water; pat dry with a paper towel.
Mix the seasoning spices together in a large bowl. Scatter on a plate.
Press the tuna into the seasoning or dust the top and bottom of the tuna with the mixture.
Heat butter or oil in a large skillet over high heat.
Sear tuna for about 1 minute per side, just until a dark crust forms.
Remove from the pan and let rest for a few minutes before slicing and serving.
Garnish with sesame seeds, sliced scallions, and serve with lemon wedges.
Notes
