I make this baked tilapia when I want dinner that feels bright and a little fancy but comes together faster than ordering takeout. The lemon garlic butter keeps the fish tender and fragrant, while a pinch of red pepper flakes wakes up the whole dish.

- Bright lemon flavor that cuts through butter
- Buttery finish with a fresh garlic lift
- Ready in about 20 minutes for weeknight cooking
- Low fuss and easy cleanup
I remember my first time making this for a small family dinner. The kids were skeptical until they tried a forkful and asked for seconds, which made the whole evening glow.
Ingredients
- Tilapia filets – mild, flaky fish that cooks quickly; choose filets that are even in thickness for uniform cooking
- Kosher Salt – simple seasoning to bring out flavors; use less for smaller filets and taste as you go
- Butter – adds richness and helps carry garlic and lemon flavors; use unsalted if you want tighter control over seasoning
- Red Pepper Flakes – optional, gives a gentle heat; add less for kids or skip entirely
- Lemons – provide zest and juice for brightness; pick firm lemons with thin skin for more juice
- Parsley – fresh herb for color and a clean finish; flat leaf parsley has better texture for chopping
Step-by-Step Instructions
- Preheat and prep – Preheat the oven to 400 F. Lightly oil a shallow baking dish or line it with parchment. Pat the tilapia filets dry on both sides with paper towel so the butter and seasonings stick and the surface roasts instead of steaming.
- Season the fish – Lay the filets in the dish in a single layer. Season both sides with kosher salt and freshly ground black pepper. Do not skip patting dry first or the fish may take longer to brown and can be soggy.
- Prep lemons and garlic – Zest one lemon into a small bowl, slice another lemon into rounds, and juice until you have about 1 to 2 tablespoons of lemon juice. Mince 2 to 3 garlic cloves very finely so the garlic disperses through the butter and does not burn.
- Make the lemon garlic butter – Melt 3 to 4 tablespoons of butter gently in a microwave or small pan until warm and glossy but not browned. Stir in the minced garlic, lemon zest, and lemon juice. Add a pinch or two of red pepper flakes if using. Taste and adjust lemon or salt as needed. Avoid overheating the butter so the garlic does not become bitter.
- Dress and top – Spoon the lemon garlic butter evenly over each filet, making sure some of the garlic distributes across the tops. Place one or two lemon rounds on top of each filet to steam and infuse flavor while baking.
- Bake and test – Bake at 400 F. Begin checking at 10 minutes with a fork. The fish should be opaque and flake easily. For safety and best texture aim for an internal temperature of 145 F. Thicker filets may need up to 20 minutes. Avoid overbaking or the fish will dry out.

You Must Know
- Lean protein rich in vitamin B12 and selenium
- Low in calories when prepared with modest butter
- Freezer-friendly if you freeze raw filets quickly and wrap tightly
This dish always reminds me of summer dinners when I would squeeze fresh lemons over fish on the porch. My favorite ingredient is the lemon zest because that concentrated citrus aroma lifts the whole plate.
Storage tips
Cool leftover fish to room temperature no longer than two hours then store in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in a 300 F oven for 8 to 10 minutes covered so it does not dry out.
Ingredient substitutions
If you do not have tilapia you can use cod or haddock with similar timing for thin filets. Swap parsley for cilantro for a brighter, slightly peppery finish. Use olive oil instead of butter for a lighter version, though the flavor will be less rich.
Serving suggestions
Serve this tilapia with steamed rice or a simple green salad and roasted or steamed vegetables. A lemon wedge at the table allows guests to add extra brightness.
Freezer meal conversion
To freeze for later, place raw filets on a tray to flash freeze for 30 minutes, then transfer to freezer bags with a squeeze of lemon and a pat of butter. Use within 2 months and thaw overnight in the refrigerator before baking as directed.
Pro Tips
- Use room temperature butter so it disperses evenly over the fish
- Zest before juicing and keep some zest aside for garnish
- Check the thickest part of the filet with a thermometer at 10 minutes
- If filets are very thin, reduce bake time to avoid drying out
- Finish with chopped parsley off heat for a fresh herbal pop
