Lemon Garlic Butter Baked Tilapia

Our family is full of serious seafood lovers so I find myself whipping up seafood recipes on the regular. This one for lemon garlic butter baked tilapia is one that no one can get enough of! 

 

Tilapia is a delicate and incredibly mild fish which means that without the right seasonings or sauces, it can easily be super boring. But this baked tilapia recipe is anything but dull! 

Instead, I’ve incorporated bold flavor by smothering the fish in a buttery, lemon-laced sauce studded with garlic, lemon zest, and smoky paprika before baking it. The result? The most moist and flavorful filet you’ll ever make — and a whole lot of happy eaters at the dinner table!

What Makes This Tilapia Crave-Worthy

Trust me — once you try this tilapia, you’ll be putting this recipe on repeat.

• Bold seasoning. I jazz up this mellow fish with the bold smokiness of smoked paprika and the brightness of tomatoes that are baked right in the same dish. 
• Low in carbs. If you’re looking to limit carbs — or you’re hosting guests who are — this can be your go-to dish. It’s full of flavor but totally keto and low-carb friendly.
• Super easy. There are only a few steps to make the dish and it has a brief cooking time, making it perfect for weeknights or when you’re hosting guests. 
• Incredibly moist. Thanks to the way that it is cooked with the sauce, this tilapia dish turns out as tender and moist as if you’d poached it. 

Ingredients for Lemon Garlic Butter Baked Tilapia

This simple list of ingredients comes together to make a show-stopping dinner that no one will ever guess is as easy as it is! 

• Tilapia Filets – This mild fish is the star of the show. You can find it in the seafood section of your grocery store. If it’s frozen, allow it to thaw overnight in the refrigerator before preparing it.
• Cherry Tomatoes – The acidity from the tomatoes balances the dish but they also become slightly sweet when cooked. 
• Coarse Kosher Salt – Salt helps to bring out the flavors of tomatoes and the seasonings.
• Ground Black Pepper – Pepper adds a bit of gentle heat to the dish, balancing out the other flavors.
• Unsalted Butter – Butter is the base of the sauce and helps to keep the tilapia moist while it’s baking. 
• Garlic – You can either mince or grate the garlic, but be sure you have uniform pieces so it’s evenly distributed in the sauce. 
• Fresh Lemons – You’ll use both the juice and zest from lemons to create a concentrated citrus flavor. 
• Smoked Paprika – The smokiness of the paprika helps to build a more complex flavor profile in the sauce. 
• Fresh Parsley – This optional garnish gives the dish a pop of color and a touch of herbaceous flavor. 

How to Make Lemon Garlic Butter Baked Tilapia

One of the best parts of this recipe is how quickly you can make it.

1. Add fish and tomatoes to baking dish. Put the fish filets into a prepared baking dish. Place the tomatoes in the dish with the tilapia. Sprinkle the fish and the tomatoes with salt and pepper. 
2. Make butter mixture. Place the butter into a small bowl and microwave in intervals until melted. Add the garlic, lemon zest, lemon juice, and smoked paprika to the melted butter.
3. Pour butter over fish. After stirring until all ingredients are combined, pour the butter mixture evenly over the fish and tomatoes. 
4. Top with lemon slices. Slice the remaining half of a lemon and top the filets with the lemon slices. 
5. Bake. Place the fish in the preheated oven and bake it for the recommended time.
6. Serve over spaghetti squash, rice, cauliflower rice, or a pasta like buttered noodles. 

How Long to Bake Tilapia

Generally, tilapia takes about 15 minutes to bake in an oven set to 400 degrees Fahrenheit. The cooking time could be slightly longer or shorter depending on the size of the fillets. 

You’ll know that tilapia is ready to come out of the oven when it has reached an internal temperature of 145 degrees Fahrenheit on an instant-read thermometer stuck into the thickest part of the fish. Also, tilapia that is fully cooked will flake easily with a fork. 

What’s Good to Eat with Lemon Garlic Butter Baked Tilapia?

One of the reasons I love serving tilapia is that its mild flavor means that it mingles well with all sorts of different side dishes. For veggies, try serving it with peas and onions, pan fried broccolini, or marinated green beans.

For starchy sides, it pairs beautifully with lemon couscous, creamy risotto, and Hasselback potatoes. On chilly evenings, I also like to serve it with soup — try pairing it with a bowl of cauliflower soup, creamy potato leek soup, or minestrone.   

Variations 

Tilapia is the perfect blank canvas for creativity in the kitchen. You can mix and match your own favorite ingredients to create any flavor profile you like. 

• Citrus – Instead of lemon juice and zest, try using limes, oranges, or even grapefruit. 
• Heat – Add a spicy kick to the fish by incorporating cayenne pepper powder or red pepper flakes. 
• Garnish – Swap out the parsley and use fresh herbs like cilantro or basil instead.
• Seasoning – Give the sauce a bit of Italian flair by using Italian seasoning or make a Mexican-inspired version with taco seasoning blend. 
• Sauces – Try baking the fish with a different sauce. Bloves sauce, honey garlic sauce, or homemade eel sauce are all good options.
