Ingredients
-
2 lbs white fish filets (such as cod, tilapia, halibut, etc.)
-
2 tablespoons olive oil
- 4 teaspoons fish seasoning (or any preferred blend)
Instructions
- Set your oven to 375°F to preheat.
- Pat the fish dry with a clean towel. Arrange the fillets on a baking sheet and coat both sides with the olive oil.
- Sprinkle the seasoning evenly over the fish.
- Bake for 15–20 minutes, or until the fillets flake easily and the internal temperature reaches 145°F.
- Remove from the oven and serve immediately.
-
The cooking time can vary based on how thick your fillets are—thin pieces finish faster.
-
Cooked fish will last 3–4 days when stored in the refrigerator.
-
To reheat, place leftovers on a lined baking sheet, add a splash of water, cover loosely with foil, and warm at 275°F for about 15 minutes.
- Using an instant-read thermometer helps prevent overcooking and keeps the fish moist.
- Can I use any type of white fish for this?
Absolutely. Cod, tilapia, halibut — they all work a treat. Use whatever you’ve got or whatever’s on sale. This recipe is wonderfully forgiving.
- Do I need fresh fish, or can I use frozen fillets?
Frozen is totally fine! Just thaw them completely and pat them dry. Excess moisture is the enemy of good texture, so don’t skip the drying — it makes all the difference.
- How do I know when the fish is perfectly cooked?
Fish is done when it flakes easily with a fork and turns opaque. If you want to be extra precise (or tend to overcook like yours truly on a busy night), aim for an internal temp of 145°F.
- My fish turned out a little dry — what went wrong?
Most likely, it baked for a few minutes too long. Fish cooks fast! Try checking a couple of minutes early next time. And don’t forget the olive oil — it keeps everything juicy and tender.
- What can I serve with this to make dinner feel “complete”?
This baked fish plays nicely with just about anything. Steamed greens, roasted veggies, rice, a fresh salad… you can’t go wrong. If you want to make it feel fancy with zero effort, add lemon wedges and a drizzle of melted butter. Boom — dinner done.
