Garlic Butter Lemon Tilapia ingredients
  • Tilapia Fillets – Either fresh or frozen, Tilapia fillets would work well. If the fillets are frozen, defrost them and pat dry before using them.
  • Butter – if you are using salted butter, you have to pay attention to the amount of salt you are using. For the best flavor, I love to use grass-fed butter.
  • Garlic – fresh garlic is the best for this recipe. You can use more or less as you’d like.
  • Lemon – we’ll use both lemon just and lemon zest that adds a bright lemon flavor and pairs perfectly with the silky, buttery texture.
  • Paprika – For a more intense flavor, use smoked paprika
  • Thyme and Oregano – you can replace them with your favorite dried herbs.
  • Salt and Pepper – to taste.

How To Bake Tilapia

I love how easy it is to make this delicious garlic butter lemon tilapia. Here is everything you have to do:

  1. Preheat the oven to 400 F degrees.
  2. Prepare the tilapia fillets. Pat dry the tilapia using paper towels, then arrange them into a baking dish.
  3. Make the marinade. In a mixing bowl, combine melted butter, lemon juice, lemon zest, and seasonings.
  4. Assemble the dish: Pour the garlic lemon butter over the fillets. Top with lemon slices.
  5. Bake in the oven for 12-15 minutes or until the fish is flakey and cooked through.
  6. Garnish with fresh parsley and red pepper chili flakes. Enjoy!

Tips For Baking Tilapia

  • If you want your tilapia fillet to have a delicious crust, you have to pat dry the fish with paper towels to remove as much moisture as possible.
  • Add parmesan cheese over each tilapia fillet 5 minutes before they are ready.
  • Check the filets after around 10 minutes to ensure they are not overcooked. They should take no more than 12-15 minutes to be done.

Storing Ideas 

  • Fridge – Store the leftover baked tilapia in an airtight container in the fridge for up to 5 days.
  • Freezer – Store this garlic butter lemon tilapia in the freezer in an airtight container for 2 months. But you need to know that once you thaw it, the texture of the fish will change a bit.
  • Reheat tilapia in the oven at 350F. I don’t recommend using the microwave to reheat fish fillets.

Frequently Asked Questions

How To Choose The Perfect Tilapia Fillets?

Look for boneless, skinless tilapia fillets with pink and white-colored flesh in any grocery shop or fish market.

What Does Tilapia Taste Like?

Tilapia is a white fish that is mild and flaky, and it doesn’t taste or smell like fish at all. I like how subtle the flavor is and how it pairs well with almost any flavor combination.

How To Know When My Tilapia Is Done?

When the flesh turns white and flakes easily with a fork, you know the tilapia is done baking. If you’re still unsure, stick a thermometer in the thickest section and see if the temperature is at or above 140°F.

Can I Use Frozen Tilapia For This Recipe?

Sure, you can use frozen tilapia. But I recommend doing that only if you forget to thaw it, and if you are using frozen tilapia, you need to know that you will have to cook it longer in the oven.
