Ingredients You’ll Need

The magic of this Baked Lemon Garlic Butter Tilapia Recipe is really in the simple, fresh ingredients working together. When you pick your tilapia, try to get fresh fillets that aren’t too thick for even cooking. I love using fresh garlic and parsley because they add so much brightness!

  • Unsalted butter: Melted, it carries the garlic and lemon flavors beautifully and helps keep the tilapia moist.
  • Fresh lemon juice: Essential for that bright, citrusy punch—freshly squeezed is way better than bottled.
  • Garlic cloves: Finely chopped to spread that incredible aroma all over the fish.
  • Dried thyme: Adds a subtle earthy note that complements the garlic and lemon perfectly.
  • Paprika: Just a touch for mild smokiness and color.
  • Ground black pepper or red pepper flakes: A little spice kick, depending on your preference.
  • Tilapia fillets: I love using 3-4 fillets, about 1 1/2 pounds total for a family of four.
  • Kosher salt: For seasoning fish evenly—it helps to bring out natural flavors.
  • Fresh parsley: Coarsely chopped for garnish—adds color and fresh herbal notes.
  • Lemon wedges: A must-have for squeezing extra zesty goodness just before eating.

Variations

I’m all about making recipes your own. This baked lemon garlic butter tilapia is super easy to tweak, whether you want to amp up the spices or keep it even lighter. Feel free to experiment and find your perfect flavor balance.

  • Spicy Kick: I once added a pinch of cayenne pepper instead of black pepper, and it gave the dish a warm heat that my family loved.
  • Herb Swap: If you don’t have thyme, fresh dill or basil can work beautifully for a different herbal twist.
  • Butter Alternative: For a dairy-free version, melted olive oil works great and keeps the fish tender.
  • Added Veggies: Throw in some cherry tomatoes or asparagus spears around the fish before baking for an all-in-one tray meal.

How to Make Baked Lemon Garlic Butter Tilapia Recipe

Step 1: Mix the Lemon Garlic Butter Sauce

Start by melting your butter so it’s warm and smooth—that consistency helps it coat the fish evenly. Stir in fresh lemon juice, finely chopped garlic, dried thyme, paprika, and black pepper. This sauce is the heart of the recipe, so take a moment to give it a good mix—your kitchen’s going to smell amazing!

Step 2: Prepare the Tilapia

Pat your tilapia fillets dry with paper towels; this step is super important because dry fish means the butter sauce will stick better. Then season both sides generously with kosher salt. I like to lay the fillets in a 9×13-inch baking dish in a single layer. If they need to overlap a bit, that’s okay, but try to keep them mostly flat for even cooking.

Step 3: Spoon Over the Sauce and Bake

Pour the lemon garlic butter mixture evenly over the fillets, making sure every piece gets some of that flavorful goodness. Pop the dish in a preheated 425ºF oven and bake for 18 to 20 minutes. You’ll know it’s done when the fish is opaque and flakes easily with a fork. I love how the butter sauce bubbles and infuses the fish during baking—it’s pure magic.

Step 4: Garnish and Serve

Right after baking, sprinkle chopped fresh parsley on top for a pop of color and freshness. Don’t forget the lemon wedges on the side—squeezing a little extra lemon juice just before eating really brightens up the dish!

Pro Tips for Making Baked Lemon Garlic Butter Tilapia Recipe

  • Dry Your Fish Thoroughly: I learned that patting the tilapia dry before seasoning helps the butter sauce stick and prevents watery baked fish.
  • Don’t Overcrowd the Baking Dish: Giving each fillet some breathing room means they cook evenly instead of steaming.
  • Use Fresh Ingredients: Fresh lemon juice and parsley make a huge difference, so skip the pre-bottled stuff when you can.
  • Watch Your Baking Time: Tilapia cooks fast—overbaking makes it dry, so set your timer and check at 18 minutes.

Garnishes

I always garnish mine with freshly chopped parsley and a couple of lemon wedges. Parsley adds a lovely fresh flavor and bright green color that makes the dish feel complete. Plus, a squeeze of fresh lemon juice right before you dig in gives a vibrant pop that you don’t want to miss.

Side Dishes

My go-to sides with this recipe are garlicky roasted broccoli and a fluffy bed of rice or quinoa to soak up all that buttery lemon sauce. Sometimes I’ll whip up a simple green salad with a light vinaigrette to keep the meal balanced but still full of flavor.

Creative Ways to Present

For a special occasion, I’ve served the tilapia on a big platter garnished with lemon slices and fresh herbs, alongside some grilled asparagus spears. It looks stunning and instantly elevates the meal when guests are over, plus the colors are so inviting!

Make Ahead and Storage

Storing Leftovers

After your delicious dinner, cool any leftover tilapia and sauce completely, then store it in an airtight container in the fridge. I usually keep it for up to 2 days, and it still tastes fresh and juicy.

Freezing

If you want to make a bigger batch, this recipe freezes well. Wrap each fillet tightly in plastic wrap, place in a freezer-safe bag, and freeze for up to 3 months. When you’re ready to eat, thaw overnight in the fridge for the best texture.

Reheating

To reheat, I recommend warming leftovers gently in a 350ºF oven for about 10 minutes to keep the fish tender and avoid drying it out. Microwaves can work too, but do it in short bursts and cover the fish to trap moisture.

FAQs

  1. Can I use other types of fish for this recipe?

    Absolutely! While tilapia is perfect because it’s mild and cooks quickly, you can swap it for cod, haddock, or even salmon. Just adjust baking time slightly based on the thickness of the fillets.

  2. Do I have to use fresh garlic or can I use garlic powder?

    Fresh garlic gives the best flavor and aroma, but garlic powder works in a pinch—just use about 1/2 teaspoon instead of the fresh cloves. The dish will be less pungent but still tasty.

  3. Is this recipe gluten-free?

    Yes! This Baked Lemon Garlic Butter Tilapia Recipe contains no gluten ingredients, so it’s safe for anyone avoiding gluten.

  4. Can I prepare this recipe ahead of time?

    You can prep the butter sauce and season the fish a few hours ahead, then cover and refrigerate. Just add the butter mixture and bake closer to serving time for the best fresh flavor.

Final Thoughts

When I first tried this Baked Lemon Garlic Butter Tilapia Recipe, I was blown away by how something so simple could taste so incredible. It’s become one of those go-to meals I can rely on when time is short but I still want to feel like I’m feeding my family something special.

Description

This Baked Lemon Garlic Butter Tilapia recipe is a quick and flavorful dish perfect for a healthy weeknight dinner. Tender tilapia fillets are coated in a zesty lemon garlic butter sauce and baked to flaky perfection, garnished with fresh parsley and served with lemon wedges for an extra burst of citrus.


Ingredients

Tilapia and Seasoning

  • 1 1/2 pounds tilapia fillets (3 to 4)
  • 1 1/2 teaspoons kosher salt
  • 1/4 teaspoon freshly ground black pepper or red pepper flakes

Lemon Garlic Butter Sauce

  • 4 tablespoons (1/2 stick) unsalted butter, melted
  • 1 tablespoon freshly squeezed lemon juice (from 1/2 medium lemon)
  • 4 cloves garlic, finely chopped
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon paprika

Garnish

  • 1 tablespoon coarsely chopped fresh parsley leaves (from 5 sprigs)
  • Lemon wedges, for serving


Instructions

  1. Preheat Oven and Prepare Butter Mixture: Heat the oven to 425ºF. In a small bowl, stir together the melted butter, freshly squeezed lemon juice, finely chopped garlic, dried thyme, paprika, and black pepper until well combined.
  2. Prepare Tilapia Fillets: Pat the tilapia fillets dry with paper towels to remove excess moisture. Season both sides evenly with kosher salt. Arrange the fillets in an even layer in a 9×13-inch baking dish, allowing slight overlap if necessary.

  4. Bake the Tilapia: Place the baking dish in the preheated oven and bake the tilapia for 18 to 20 minutes, or until the fish is opaque, flakes easily with a fork, and is cooked through.
  5. Garnish and Serve: Remove the tilapia from the oven and sprinkle with freshly chopped parsley. Serve the baked fish with the buttery sauce from the baking dish and garnish with lemon wedges for squeezing over the top.

Notes

  • Be careful not to overcook the tilapia to keep it moist and tender.
  • If you prefer a spicier dish, increase the red pepper flakes slightly.
  • Use fresh parsley for a bright, fresh flavor, but dried parsley can substitute in a pinch.
  • This recipe pairs well with steamed vegetables, rice, or a light salad.
  • Make sure to pat the fish dry before seasoning to help the seasoning stick better.
