  1. Rub the fish fillets with the crushed garlic, then place them in a shallow, non-reactive dish. Spoon the olive oil over the fish until they are coated. Place the onion on top of the fish. Cover the fish and refrigerate overnight to allow the fish to soak in the marinade.
  2. Preheat the oven to 350 degrees F (175 degrees C).
  3. If baking the fish, transfer it to a 9x13 inch baking dish along with the olive oil, garlic, and onion. Sprinkle the fish with the cayenne or white pepper. If you are grilling the fish, wrap the fish and oil, garlic, onion, and pepper in aluminum foil.
  4. Bake at 350 degrees F (175 degrees F) for 30 minutes.

Very tasty! I prepared mine a little differently of course, I can't help myself. I sliced my onions thin rather than chopping or dicing. I used a 5 pepper spice blend rather than cayenne. I laid the filets on top of some pre-cooked bacon I had leftover from breakfast. For the ingrediants, I added the oil, garlic, onions, salt and pepper to a small microwaveable container. I mixed these items together and cooked on high for 2 minutes, stirring half way through. I laid the bacon in the casserole dish, the filets on top, then covered with the oil/onion/garlic mix. I refridgerated for only an hour, then added an appropriate amount of 5 spice blend and covered with foil. I baked for the recommended 30 minutes. It was excellent, my husband loved it and so did I! I'll definately serve this or any variation of it again!


This is my new favorite recipe for Tilapia. I did modify the recipe to suit my taste buds. I didn't marinade this at all. I used my roasted garlic and spread two cloves on each piece of fish, added black pepper and salt. Drizzled olive oil and chili oil (Chinese grocer carry this) on fish. The last thing I added was Pappy's Rub on top of the onions (like a canjun spice mix). I used my mandolin slicer to thinly slice the onions. Baked for 30 minutes and broiled another 10 minutes. The onions taste more like onions rings when they are broiled and get crunchy. We ate 6 pieces between the two of us. DEEEEVine.


This was great. I marinated it only about 4 hours and baked it, serving it atop wilted spinach. I used less onion and added some basil. Next time I fix it I will add a little less olive oil (there was a LOT in the dish after cooking). I haven't had much luck fixing fish, although I order it frequently when dining out; now this will become a regular at our house!
