    • How to Tell if Brussel Sprouts Are Bad?

    Whether you just got them from the store or they've been sitting in your fridge for a while, it's important to know the signs of good and bad brussel sprouts!

    I have eaten my fair share of brussel sprouts and have come across enough bad batches from the store to know what to avoid. I hope this article will teach you everything you need to know about brussel sprouts!

    What Are Brussel Sprouts?

    Brussel sprouts are a form of cabbage that is known for its edible buds/sprouts. They are in the cruciferous family and got their name because they were cultivated in Brussels, Germany.

    What Does a Good Brussel Sprout Look Like?

    Fresh brussel sprouts are firm with tight leaves. They smell earthy and not like cabbage.

    How to Tell if Brussel Sprouts Are Bad?

    Bad brussel sprouts can have a bad smell, similar to old cabbage. They might be a lighter green color, have brown edges, can be moldy, or even slimy.

    Quick Inspection Tips

    If you can reveal a green, firm, brussel sprout center, you can typically still eat the sprout. Just remove any leaves that are loose or show signs of decay, and cut off the stems to reveal a fresh, firm stem.

    Cut the sprout in half and see what the center looks like. Use your best judgment on whether to eat or not.

    If you are really unsure, it is always better to be safe than sorry, so toss or return your produce.

    Black and Brown Stem

    If the stem of the brussel sprout is black or brown, or there are black spots on the leaves, it is starting to go bad or has gone bad. Sometimes you can remove a bad outer leaf, similar to cabbage, and still eat the inside, if there are no other signs of decay.

    If you pull back a few leaves, you can still eat the good, firm, inside.

    How to Tell If Raw Brussel Sprouts Are Bad?

    Raw sprouts are bad if there is mold present, all their leaves are loose, the leaves are turning yellow/brown, or if the sprout is soft and squishy.

    How to Tell If Cooked Brussel Sprouts Are Bad?

    There will usually be a sour odor, and the brussel sprouts might be extra liquidy, mushy, and there could be mold. Cooked brussel sprouts should typically be eaten within 2-3 days once cooked.

    Don't worry, I promise not to spam you!

    Overcooked brussel sprouts will release a sulfurous smell, especially when boiled. This is where a lot of the hate for these tasty sprouts come from!

    Bugs in Raw Brussel Sprouts?

    Sometimes, when you are removing the outer loose leaves or even when you cut the sprout in half, you will see evidence of where a worm ate its way through the sprout. 

    If there are only a few sprouts that show this, I will just cut those pieces off (or toss the entire sprout) and cook the rest.  If the entire bag/bunch of sprouts has evidence of being eaten by worms, I will often return the produce to the store and not eat it.

    Above, you can see evidence of a worm eating the outside leaves (top left), evidence of a worm eating inside the brussel sprouts (top right), and leftover worm poop and some dirt inside the leaves of the brussel sprouts (bottom).

    What are Brussel Sprouts Good For?

    Brussel sprouts are high in fiber, potassium, Vitamins A, C, and K. They even have 3 grams of protein for every cup!

    Frequently Asked Questions

    Can You Freeze Brussel Sprouts?

    Yes! They need to be blanched first, but will freeze anywhere from 12-16 months.
    The method for blanching and freezing brussel sprouts is the same as broccoli, so check out how to freeze broccoli here!

    How Long Do Brussels Sprouts Last ?

    Raw on the counter, they will last 3-4 days; raw in the refrigerator, they will last 1-2 weeks. Cooked brussel sprouts will keep 2-3 days in the refrigerator.

    What Do Brussel Sprouts Taste Like?

    Brussel sprouts have a milder cabbage flavor and are much denser. ย The smaller the sprout, the sweeter the flavor, whereas the larger sprouts will taste a bit more like cabbage.ย 

    How Do I Check the Texture to Tell if Sprouts Are Bad?

    Fresh sprouts are firm and tight. If they feel soft, mushy, or slimy when you squeeze them gently, it's a sign they've started to spoil.

    Can I Eat Brussels Sprouts With Some Bad Outer Leaves?

    If only a few outer leaves are yellow or wilted, you can peel those away and eat the rest, but if most leaves are discolored or slimy, it's safer to discard them.

    Should You Refrigerate Brussel Sprouts?

    Yes. Uncooked/raw brussel sprouts will last 1-2 weeks when refrigerated.
