Extra Tips for Successfully Vacuum Sealing Fish

Vacuum sealing fish makes prepping and cooking your meals easier than ever, but there are some tips that you can do to simplify the vacuum sealing process.

First, you can season your fish before you vacuum seal it. This removes any prep work that you will have to do when it’s time to cook your fish. Just allow the pieces to thaw and then place them on the stove or grill! We suggest you season your fish with spices. If you want to season your fish in a light sauce, let it sit for about an hour and then gently wipe off the sauce before putting a vacuum sealing it.

Another important tip is to mark every piece of fish that you seal. If you’re not planning on eating your fish for weeks to months, you may forget what you caught. A few quick marks with a permanent marker can help you remember what you have stored in your freezer.
