Tilapia is a mild white fish with thin fillets that cook quickly, making it ideal for a weeknight main dish. It cooks evenly in the oven and is totally hands off—no need to flip the fish on the stovetop—freeing you up to make any side dishes.

The straightforward preparation and quick baking time make this tilapia recipe perfect for a busy evening. Tilapia is a lean fish, low in calories and high in protein, and tends to be one of the cheapest seafood options out there. You can find it fresh at the seafood counter or frozen, and either will work for this recipe. You also don't have to worry about mercury because the vast majority of tilapia sold at the supermarket is farmed in closed tanks, making it relatively low in mercury. (Look for tilapia that is farmed using environmentally friendly conditions for the best fish.)

Scale this recipe up or down to make the perfect amount for your family. Baked tilapia makes a fabulous meal with steamed rice or a roasted potatoes. Brussels sprouts or broccoli are great with fish, but any steamed vegetable or salad would make a good side, too. Tilapia is a bit of a culinary blank slate.

  • Tilapia should be cooked to a minimum temperature of 145 F (63 C) or until the flesh is opaque and flakes easily with a fork. Don't overbake tilapia since it can easily dry out.
  • Small individual baking dishes are convenient because they go from the oven to the table, and they make a nice presentation.

Recipe Variations

  • Make this recipe dairy free by using vegan butter or olive oil.
  • Add 1 teaspoon of finely minced fresh garlic to the butter mixture or about 1/2 teaspoon of garlic powder.
  • Omit the green onions and add another herb to the lemon butter mixture. Fresh chopped dill or fresh thyme are both good with fish.
  • Replace the parsley with fresh chervil or use about 1/2 teaspoon of dried chervil.
  • Add a little spice with a sprinkle of smoked paprika or crushed red pepper flakes.
  • Sprinkle a tablespoon of capers over the fish before baking.

How to Store and Freeze Baked Tilapia

Leftover baked tilapia will keep for about two days in an airtight container in the fridge. If you freeze it, wrap it well. It should keep for up to six months, but it will taste best by three months. Defrost in the fridge, and gently reheat it in the oven or on the stovetop.
