Healthy Broiled Tilapia for a Fast, Flavorful Dinner

This broiled tilapia pairs mild white fish with lemon, garlic, paprika, and parsley for a bright, savory main dish. A hot broiler cooks the fillets quickly, while a simple coating of olive oil and seasonings keeps the method straightforward for a weeknight meal.

Ingredients

4 tilapia fillets, 5 to 6 ounces (140 to 170 g) each, thawed if frozen and patted dry
1 tablespoon olive oil (15 ml)
1 medium lemon, finely zested and juiced, about 1 teaspoon zest (2 g) and 2 tablespoons juice (30 ml)
2 garlic cloves, finely grated or minced (about 6 g)
1 teaspoon sweet paprika (2 g)
1/2 teaspoon fine salt (3 g)
1/4 teaspoon freshly ground black pepper (about 0.5 g)
2 tablespoons chopped fresh parsley (about 8 g)
1 lemon, cut into wedges for serving (about 150 g)

Instructions

Heat the broiler and prepare the pan. Arrange an oven rack so the fish will sit about 5 to 6 inches (13 to 15 cm) below the broiler element. Turn the broiler to high and let it preheat while you prepare the fish. Line a rimmed metal baking sheet with foil for easier cleanup; lightly oil the foil or use a broiler-safe rack set over the pan. Do not use a glass baking dish under the broiler.
Dry the fillets. Blot both sides of the tilapia with paper towels. Removing surface moisture helps the seasoning adhere and reduces steaming. If a fillet has a very thin tail end, tuck it under slightly so it is closer in thickness to the rest of the piece and less likely to overcook.
Mix the seasoning. In a small bowl, stir together the olive oil, lemon zest, lemon juice, garlic, paprika, salt, and black pepper. Brush or spoon the mixture over both sides of each fillet. Arrange the fish in a single layer on the prepared pan, leaving a little space between pieces so hot air can circulate.
Broil the fish. Set the pan under the broiler and cook for about 4 minutes. Carefully rotate the pan if your broiler heats unevenly, then continue cooking for about 3 to 4 minutes. The fillets are thin, so check early rather than relying only on the clock. There is no need to turn them over unless your broiler or pan browns the top unevenly.
Check for safe doneness. Insert an instant-read food thermometer sideways into the thickest part of a fillet. The USDA FSIS safe minimum internal temperature for fish is 145°F (63°C); cook until it reaches that temperature and the flesh is opaque and flakes easily with a fork. If needed, return the pan to the broiler in 1-minute increments and check again. Avoid judging doneness by color alone, since fillet thickness and lighting can make that unreliable.
Finish and serve. Transfer the cooked fish to plates, scatter the parsley over the top, and serve with lemon wedges. The fillets are delicate, so use a wide spatula and lift from underneath rather than trying to pick them up with tongs.

Tips

Choose fillets of similar thickness. Tilapia pieces can vary a lot in shape. Similar-sized portions finish at about the same time; if one is much thinner, check it separately and remove it as soon as it reaches 145°F (63°C).
Dry, but do not over-season. Patting the fish dry helps the oil and spices cling. The measured salt gives a lightly seasoned result; if serving with salty sides or a salty sauce, keep it as written rather than adding extra before cooking.
Use a substitute for fresh parsley if needed. Chopped cilantro or dill works well in the same amount, though each gives the finish a different character. If using dried parsley, use 2 teaspoons (about 1 g) and mix it into the oil before brushing so it can soften.
Watch closely near the end. Broilers vary in intensity, and thin tilapia can go from tender to dry quickly. Keep the pan at the recommended distance, check the thickest section with a thermometer, and add cooking time in short increments.

Serving Suggestions

Serve the fillets immediately with a grain or starch that can catch the lemony juices. Steamed rice, couscous, quinoa, or boiled baby potatoes all make easy partners. For a more substantial plate, add a green vegetable such as broccoli, green beans, asparagus, or sautéed spinach. A crisp salad with cucumber, tomatoes, and a simple vinaigrette gives the meal a fresh contrast to the warm garlic and paprika seasoning.

If you want a sauce, keep it light and serve it on the side so the broiled surface stays visible. Plain yogurt mixed with lemon and chopped herbs, a spoonful of salsa, or a small dish of olive oil and extra lemon are all simple options. For tacos, break the cooked fish into large flakes and serve with warm tortillas, shredded cabbage, avocado, and lime. Take care when lifting the fillets, since tilapia flakes readily once cooked.

Variations

Make it more citrus-forward: Add 1 teaspoon (5 ml) of orange juice to the seasoning mixture along with the lemon. The orange adds a mild sweetness; keep the lemon zest so the flavor remains bright. Avoid adding a thick layer of citrus slices over the fish before broiling, because they can block direct heat and make cooking less even.

Use a smoky spice blend: Replace the sweet paprika with 1 teaspoon (2 g) smoked paprika. For a gentle warm note, add 1/8 teaspoon (about 0.3 g) ground cumin. Smoked paprika can dominate the mild fish, so begin with the listed quantity rather than adding a heavy coating.

Add a little heat: Stir 1/8 to 1/4 teaspoon (about 0.3 to 0.6 g) cayenne pepper into the oil mixture. The lower amount gives a subtle warmth; use the upper amount for a more noticeable kick. You can also serve sliced jalapeño at the table so each person can adjust their portion.

Try another mild white fish: The same lemon-garlic seasoning works with cod, haddock, or pollock. Since those fillets may be thicker or thinner than tilapia, use the thermometer rather than copying the exact cooking time. Cook any fish to 145°F (63°C) in its thickest part.

Storage and Reheating

Refrigerate leftover tilapia within 2 hours of cooking, placing it in a shallow airtight container so it cools promptly. Keep it refrigerated at 40°F (4°C) or below and use it within 3 to 4 days. If the fish has been sitting at room temperature for more than 2 hours, discard it rather than saving it. For longer storage, freeze the cooled portions in a freezer-safe container for up to 2 months for best texture. Thaw frozen leftovers in the refrigerator, not on the counter.

To reheat, place the fish in a covered oven-safe dish with a teaspoon of water or lemon juice to limit drying, then warm in a 300°F (150°C) oven until the center reaches 165°F (74°C). Check with a food thermometer, as reheating time depends on portion size. A microwave also works: cover loosely, heat in short intervals at medium power, and check the center temperature. The fish may become firmer after reheating, so avoid repeated warming and chill any uneaten portion promptly.

Frequently Asked Questions

Can I broil tilapia from frozen?
Thawing first gives the most even result and makes it easier to pat the fish dry and apply the seasoning. Thaw frozen fillets overnight in the refrigerator, or keep them sealed in a leakproof bag and place the bag in cold water, changing the water every 30 minutes. If cooking from frozen, separate the fillets as they thaw enough to handle, dry them thoroughly, and expect the cooking time to increase; verify 145°F (63°C) in the thickest part.

How do I keep tilapia from drying out?
Use fillets with a similar thickness, place the pan at the stated distance from the broiler, and start checking after about 6 to 7 minutes. A thermometer is more dependable than waiting until the fish looks deeply browned. Remove each portion once it reaches 145°F (63°C), even if another, thicker piece needs more time.

Should I flip the fillets while broiling?
Usually not. Thin fillets cook quickly from the broiler’s direct heat, and flipping can break them apart. If the tops brown unevenly, rotate the baking sheet instead. If you choose to flip because the fillets are unusually thick, use a thin, wide spatula and turn them gently after the first side has begun to set.

Can I use dried garlic or bottled lemon juice?
Fresh garlic and lemon provide the clearest flavor, but substitutions are possible. Use 1/4 teaspoon (about 0.8 g) garlic powder in place of the two fresh cloves, adding it to the oil mixture. Bottled lemon juice can replace the fresh juice in the same amount, but it will not provide zest; the dish will taste less aromatic, so add a little extra parsley if you like.

What if my broiler only has a low setting?
Use the high setting if available, since the recipe is designed for direct, intense heat. With a low broiler, the fish may take longer and may not brown as much. Keep the pan at the same approximate distance, begin checking at 7 minutes, and use the internal temperature—not browning—as the final safety check.
