How To Properly Store Brussels Sprouts

You can buy Brussels sprouts off the stem or attached to the stem. However, most times, retailers sell the ones with no stems attached.

If you buy Brussels sprouts with the stem attached, detach the heads from the stem and throw the stalks out.

The best place to store Brussels sprouts is in the refrigerator. I highly recommend placing them in a container that allows for unrestricted airflow. If possible, wrap the sprouts in a damp towel to retain as much moisture as possible.

Storing Brussels at room temperature is not ideal since their quality will deteriorate at a fast rate. However, if you plan to use them that same day or the day after, you can leave them on your kitchen counter.

Can you Freeze Brussels Sprouts?

As mentioned above, you can freeze Brussels sprouts to extend their shelf life. Freezing Brussels sprouts may take time, but it is worth all the trouble. Here is how to go about it.

The first step is to prepare the vegetables. Do this by trimming them and getting rid of the rough outer leaves.

Wash the heads thoroughly, ensuring you get rid of any dirt or insects, then divide them into groups of the big, medium, and small sprouts.

After doing so, you should blanch the sprouts. Boil some water in a saucepan, then submerge the heads in the boiling water. Blanch the big heads for 5 minutes, the medium ones for 4 minutes, and the small ones for 3 minutes.

Once blanched, move the heads to a saucepan filled with cold water. Doing this will ensure that the sprouts stop cooking. If you are freezing a big batch of Brussels sprouts, let them sit in the water until the water becomes somewhat warm.

Drain the water, then place the heads on a dry cloth and let them dry for approximately 20 minutes. Ensure the Brussels sprouts are completely dry before moving to the next step.

Portion the sprouts depending on how much you eat at a time, then transfer them to Ziploc bags or freezer-safe airtight containers. Place the bags or containers in the freezer for up to 16 months.

Tips on buying fresh Brussels sprouts

Here are a few tips on buying fresh Brussels sprouts every time to get the best out of them.

If you have the option, buy Brussels sprouts that are still attached to the stem. 

  1. Most times, they last longer than those detached.
  2. Always inspect the leaves. Avoid the ones that are yellowish or brownish. Instead, go for the bright green ones.
  3. The sprouts should not have pits or cracks. Pits and cracks indicate mold growth.
  4. Always choose smaller sprouts. You’ll notice that they are sweeter compared to big Brussels sprouts.
  5. Try buying sprouts of similar sizes. This way, they will cook evenly, and you’ll have a better experience.
  6. Smell the sprouts. They should smell fresh and earthy. If their aroma is similar to that of cabbage, they are old. Don’t buy them.
  7. Only buy Brussels sprouts that are refrigerated. The ones displayed at room temperature are likely to go bad at a fast rate. They may turn yellow or wilt before you get the chance to cook them.
  8. Don’t buy puffy and soft sprouts. Go for the ones that feel compact and firm.
