How To Freeze Brussel Sprouts

The best way to freeze Brussel sprouts, especially if you are not sure how you want them cooked it to blanch them first. This is almost like freezing them raw. They won’t be cooked, which leaves it open for you to choose what to do with them at a later date.

There is a little work involved, so let’s get started and find out how you blanch and freeze Brussel sprouts.

  1. Clean Your Sprouts
    Trim and prep your sprouts first. You will also want to wash them and let them dry completely. If you are worried about insects, you can soak the sprouts in cold water with a tablespoon of salt added. This will bring out any bugs, so you can be sure you are freezing only the best sprouts.
  2. Blanch Them
    Set a pan of water to boil. While the water is coming to boil, prepare a large bowl of ice water next to the stove. Add your sprouts to the boiling water. Add the largest ones first and the smallest last. You are aiming to boil the largest sprouts for about 4 minutes and the smallest for about 3 minutes.
  3. Cool Them
    Once the time is up, remove the sprouts from the boiling water and plunge them into the ice water. Once the sprouts are cool you can drain and dry them.
  4. Bag Them
    Label some freezer bags with the name and date. Pop a portion of sprouts into each bag.
  5. Freeze
    Seal the bags and freeze.

How to Freeze Roasted Brussel Sprouts

If you know you want to have your sprouts roasted or you are freezing leftover roasted sprouts, then the great news is you can freeze roasted Brussel sprouts too. Here is how.

  1. Roast Your Sprouts
    Roast your Brussel sprouts with your favourite herbs and spices. Be bold and brave with the seasonings you use, as sprouts are particularly good at taking on flavours. Once cooked, allow them to cool completely.
  2. Flash Freeze
    Grab a baking sheet and lay out the sprouts on top into a single layer. Make sure the sprouts are not touching. This step is to ensure they don’t stick together while being frozen. Freeze for an hour or two and then take the baking sheet out of the freezer and transfer the sprouts into freezer bags.
  3. Final Freeze
    Label the bags with the date and the contents and put them back into the freezer.
