Baked Tilapia Garlic Butter

I pulled this together on a rainy Tuesday when the fridge was looking bare and takeout felt too lazy. All I had were some tilapia fillets I'd frozen weeks earlier and a neglected lemon rolling around in the crisper drawer. Twenty minutes later, the kitchen smelled like a seaside bistro, and I realized I'd been overthinking dinner for months.

The first time I made this for my parents, my dad looked up from his plate and asked if I'd ordered it from somewhere. He's not big on compliments in the kitchen, so I knew the garlic and lemon had worked their magic. My mom asked for seconds, which she never does, and I've been keeping tilapia stocked ever since.

Ingredients

• 4 tilapia fillets (about 150 g each): Tilapia is mild and forgiving, so it won't punish you if you're new to cooking fish, and it soaks up the garlic butter like a sponge.
• 4 tablespoons unsalted butter, melted: Unsalted lets you control the seasoning, and melted butter clings to every crevice of the fish instead of sitting in clumps.
• 3 cloves garlic, minced: Fresh garlic is non-negotiable here, the jarred stuff tastes flat and won't fill your kitchen with that intoxicating aroma.
• 2 tablespoons fresh lemon juice: Freshly squeezed lemon juice brightens the richness of the butter and keeps the fish from tasting heavy.
• 1 teaspoon lemon zest: The zest adds a floral, aromatic layer that bottled juice just can't match.
• 2 tablespoons fresh parsley, chopped: Parsley adds a pop of color and a clean, grassy note that balances the garlic.
• ½ teaspoon salt: Just enough to bring out the natural sweetness of the fish without overpowering it.
• ¼ teaspoon black pepper: A gentle warmth that doesn't compete with the lemon or garlic.
• ¼ teaspoon paprika: Paprika adds a hint of smokiness and a beautiful golden color to the butter sauce.
• Lemon wedges: A final squeeze at the table wakes up every bite and makes the dish feel restaurant quality.
• Additional chopped parsley: Extra parsley makes the plate look alive and gives your guests something green to admire.

Instructions

Preheat and Prep:

Set your oven to 200°C (400°F) and lightly grease a baking dish big enough to lay the fillets flat without overlapping. Crowding them will steam the fish instead of letting it bake evenly.

Dry the Fillets:

Pat each tilapia fillet dry with paper towels and arrange them in the dish. Moisture on the surface will dilute the butter sauce and prevent browning.

Make the Garlic Butter:

In a small bowl, whisk together melted butter, minced garlic, lemon juice, lemon zest, parsley, salt, pepper, and paprika until everything is evenly distributed. The smell alone will make you hungry.

Coat the Fish:

Pour the garlic butter mixture over the fillets, using a spoon to make sure each one gets an equal share. Don't be shy, every drop counts.

Bake Until Flaky:

Slide the dish into the oven and bake for 15 to 18 minutes, until the fish flakes easily with a fork and looks opaque all the way through. Overcooked tilapia turns rubbery, so check early.

Optional Broil:

If you want a lightly golden top, switch the oven to broil for 1 to 2 minutes, watching closely so it doesn't burn. This step is optional but adds a nice finish.

Garnish and Serve:

Plate the fillets, spoon any remaining butter from the dish over the top, and garnish with lemon wedges and fresh parsley. Serve immediately while it's hot and fragrant.

I brought this to a potluck once, worried it was too simple to impress, and three people asked for the recipe before I'd even finished my own plate. One friend texted me the next day saying she'd already made it twice. That's when I realized simplicity isn't a weakness, it's a superpower.

Choosing the Right Fish

Tilapia is gentle and approachable, but if you can't find it or want to switch things up, cod and haddock both work beautifully with this garlic butter treatment. I've also used sole when it was on sale, and it came out delicate and sweet. Just make sure whatever you choose is firm enough to hold its shape in the oven and not fall apart when you serve it.

What to Serve Alongside

I usually pair this with steamed broccoli or green beans, and either jasmine rice or roasted baby potatoes to soak up the extra butter. A crisp salad with a lemon vinaigrette feels right if you want something lighter. The key is to keep the sides simple so the garlic and lemon stay the stars of the plate.

Make It Your Own

This recipe is a blank canvas, and you can dress it up or down depending on your mood. I've added a pinch of crushed red pepper flakes when I wanted a little heat, and once I stirred in a teaspoon of Dijon mustard to the butter for a tangy twist. You can also swap the parsley for fresh dill or cilantro if that's what you have on hand.

• Try adding a splash of white wine to the butter sauce for a more elegant finish.
• Toss in some cherry tomatoes around the fillets before baking for bursts of sweetness.
• Sprinkle grated Parmesan over the top during the last few minutes for a cheesy, golden crust.
