How long should you cook fish in foil in the oven?

15-20 minutes depending on the type and thickness of the fish. Some meaty fish will require longer cooking time while a thin tilapia may only take up to 15 minutes to fully cook.

Look up the specific fish you are cooking to determine how long you should cook for.

How do you wrap fish in aluminum foil?

Some people prefer to use one piece of foil and fold over the fish, tucking the open sides tightly. But I personally prefer to use two pieces of foil, this way you can remove the top foil and still have the bottom foil to serve the fish neatly.

Arrange fish and vegetable on top of a piece of foil that is large enough to accommodate its packet content. Then place a second piece of foil over the fish and vegetables and tuck both bottom and top foil tightly on all sides.

What does wrapping in foil do?

There are a few good reasons to cook fish in foil. The fish comes out very moist and flaky, almost steamed-like. This method also helps prevent from oil/ grease spills and the packets make for a fun individualized serving.

What to serve with fish and vegetables:

Instant Pot Quinoa – Instant Pot Brown Rice or Instant Pot Potato Salad – these are three great choices of starch/ carbs that will go great with the fish in foil packets.

Tortellini Pasta Salad or Tomato Basil Tortellini

Simple Chickpea Salad
