Preheat your oven to 375°F (190°C) and then lightly brush the bottom of your casserole dish with olive oil.
Place the tilapia fillets in the dish in a single layer.
Squeeze the juice of one lemon evenly over the fish. Season them with Slap Ya Mama, or your favorite fish seasoning. We typically use about ½–1 teaspoon per fillet.
Scatter the cherry tomatoes around the edges of the casserole dish and then place three lemon slices on top of each fillet.
Cover the baking dish tightly with aluminum foil and bake the fish for 20–25 minutes, or until the fish is opaque and flakes easily with a fork.
Remove the dish from the oven and immediately sprinkle the fresh basil over the fish and tomatoes. Serve it right away with rice, spooning some of those tomatoes and pan juices over the top.
