Tilapia is safely and nicely cooked when it reaches an internal temperature of 145°F (63°C) at the thickest part of the fillet, measured with a food thermometer.

Quick Scoop

  • Target internal temp: 145°F (63°C) for tilapia to be safe and flaky.
  • Visual cues: Flesh turns opaque white and flakes easily with a fork.
  • Oven temp range: Common baking temps are 350–400°F (175–200°C); time depends on thickness (roughly 10–20 minutes for typical fillets).

Simple oven guideline

  • Preheat oven to 375°F (190°C).
  • Season tilapia and place on a lightly oiled baking sheet.
  • Bake about 15–20 minutes (thinner fillets closer to 10–15, thicker closer to 20), then check with a thermometer; pull it out once the center hits 145°F.

If you don’t have a thermometer, go by looks and texture: opaque all the way through and flakes easily, with no translucent or jelly-like spots in the center.

Mini FAQ

  • Is 400°F okay? Yes, just check earlier (around 10–12 minutes) so you don’t dry it out.
  • Is 350°F okay? Yes; it’s gentler but takes longer, often around 20–25 minutes depending on thickness.
