Time: 20 minutes
Serves: 4


  • 1 large tomato, sliced 
  • 1 Tbs. extra-virgin olive oil
  • 4 6 oz. fillets of white fish (tilapia, haddock, or hake)
  • 2 Tbs. mayonnaise
  • ½ tsp. Old Bay or other seafood seasoning
  • 1/8 tsp. freshly ground black pepper
  • lemon, cut into wedges


  1. Preheat the oven to 375°F. On a large foil-lined baking pan, place the tomato slices in a single layer. Drizzle with the oil.
  2. Blot the fish dry with a paper towel, then place the fillets on the baking pan with the tomatoes. In a small bowl, mix the mayonnaise with the Old Bay seasoning and the pepper. Spoon the mayonnaise mixture over the fish.
  3. Switch the oven to broil. Place the baking pan 6–8 inches under the broiler and broil until the tomatoes are bubbling hot and the fish flakes easily with a fork, 5–8 minutes.
  4. Top the fish with the tomato slices. Serve with the lemon wedges.
