Healthy Baked Tilapia Recipe

When looking for easy and healthy dinners, I often turn to fish recipes.  Fish is usually pretty easy to prepare and cook, and also is a healthy option.  Fish generally is a good source of protein and sometimes healthy fats as well.  Tilapia is a leaner fish, so is a great source of protein for fewer calories than some other sources.

What is Tilapia?

Tilapia is a mild white fish, which has become popular because it is mild tasting, easy to farm and is a great source of protein. It is also low in fat and calories.  A 3 ounce serving of Tilapia has 20 grams of protein and only 2.5 grams of fat and 110 calories! However, recent studies have shown that it is important to be aware of where your tilapia comes from. You can check the Monterey Bay Aquarium Seafood Watch to see where the best places are to get your Tilapia from.

Oven Baked Tilapia

I love this Lemon Butter Baked Tilapia because it is so fast and easy but packed with flavor!  Tilapia is a mild white fish, so it needs a little help in the flavor department.  Butter, garlic and lemon to the rescue!  Lemon butter is a classic flavor for fish, and it works perfectly here along with garlic, parsley and a hint of red pepper.  I punched up the lemon flavor with both lemon juice and zest, along with lemon slices. A simple sauce of lemon, butter and garlic takes just minutes to put together.  Then the tilapia filets are bathed in the buttery lemon sauce and quickly baked in the oven.

How Long to bake Tilapia in the oven

Tilapia cooks very quickly in the oven. Lemon Butter Baked Tilapia will cook in about 10-12 minutes at 400 degrees.  I like to finish this tilapia recipe under the broiler to give it a little color.  You know the fish is done when it flakes easily with a fork or reaches 145 degrees internal temperature.

    Very tasty and a nice change from breaded fish filets. I used lemon pepper in addition to salt just for an added zing (and I had some I needed to use up) and lemon juice concentrate since I forgot to buy lemons at the grocery. I’m sure the fresh lemons and juice would be wonderful and I will not forget to purchase them next time. And there will definitely be a next time!

    1. Hi Calylla, Lemon pepper seasoning won’t give it the same flavor as fresh lemon juice and zest. You can definitely give it a try though!

    2. I used lemon pepper seasoning and about 2Tbsp lemon juice from concentrate when I made it the first time and it was still good. Different than the original recipe, but still good. You could probably get away with cutting out the lemon juice if you have none, but it will be a more savory garlic flavor profile. Just pat the fillets dry and coat them I the lemon pepper seasoning, then mix the remaining ingredients into the melted butter and proceed with following the original recipe from there.

  2. Hi! I enjoy your website. What other kinds of fish would work well in this recipe? Any mild white fish?
