Prep the tilapia: Start by patting the tilapia fillets dry with paper towels. This will help the seasoning stick better and ensure a nice crisp texture when cooking.

Make the seasoning: In a small bowl, mix together the paprika, garlic powder, onion powder, cayenne pepper, dried oregano, thyme, salt, and black pepper. Stir until the spices are well combined.

Coat the fillets: Rub the seasoning mix generously over both sides of the tilapia fillets. Be sure to cover every inch of the fish to get that delicious blackened crust.

Heat the skillet: Place a large cast-iron skillet over medium-high heat. Add the olive oil or melted butter and allow it to heat up, making sure the skillet is nice and hot.

Cook the tilapia: Carefully place the seasoned fillets into the skillet. Cook them for about 3-4 minutes on each side, or until the fish is golden brown on the outside and flaky on the inside.

Finish and serve: Once the fillets are cooked, remove them from the skillet and squeeze fresh lemon juice over the top. This adds a burst of brightness that complements the smoky flavors. Serve immediately with your favorite sides.
