Sprouting Broccoli Seeds

Even if you don’t have a green thumb, you can easily learn how to grow broccoli sprouts from broccoli seeds. Broccoli sprouts do not come from a regular head of broccoli, but from little broccoli seeds that you can purchase.

The best part about sprouting broccoli is that you don’t need to have a green thumb. All you need are a few tools to start sprouting broccoli seeds right on your kitchen countertop.

Why Broccoli Sprouts?

My interest in growing broccoli sprouts started way back in 2012 when I learned how nutritious broccoli sprouts are. They contain sulphoraphane that has research behind it showing its cancer-fighting properties. It is a powerful antioxidant that we should be consuming as often as possible.

I am a cancer survivor always looking for ways to reduce my risk of recurrence. So, I make broccoli sprouts at least a few times a month and try to eat them as often as possible. Since it’s such an easy thing to do, I wanted to share the process with you.

Step-by-Step Guide for Sprouting Broccoli

The easiest method is to use a Mason jar with a strainer lid to grow the sprouts, but I’ve tested a few different methods. My favorite way is to use a Sproutamo Easy Sprout Sprouter that is absolutely perfect for broccoli sprouts.

Step 1: Soak the Broccoli Seeds

So, you need to have both a sprouting vessel and broccoli seeds to get started.

As I mentioned above, you need to soak your broccoli seeds in a small bowl with filtered water for about 12 hours to start the sprouting process. You can put the bowl in a dark or light room for the first 12 hours.

Step 2: Transfer Seeds to Sprouting Vessel

After you have soaked the seeds, it’s time to rinse them and transfer them to your sprouting vessel.

Step 3: Sprout & Rinse

For the next 48 hours, you’ll need to keep the sprouts in a cool, dark place, such as a dark pantry or a kitchen cabinet. You’ll also need to rinse the sprouts at least 3 times a day. That’s when the Easy Sprouter comes in really handy. It has a built-in strainer so all you have to do is hold it under the kitchen sink to rinse the sprouts.

You’ll see that the sprouts will start to form, although they will be more yellow than green until you reach the last step.

Step 4: Move the Sprouting Vessel Out of the Dark

Once the sprouts have reached about a half-inch to full-inch in length, it’s time to move the sprouting vessel out of the dark and expose it to some sun. We don’t want to put the vessel in direct sunlight, but just in some nice indirect light for about 12 more hours. This will help develop the lovely green color that broccoli sprouts should have.

Step 5: Harvest the Sprouts

On about day 4 or 5, that’s when it’s time to harvest your sprouts. They should be fully grown and nice and green. All you have to do to harvest them is give them one really good final rinse and transfer them to a glass bowl with a lid. Store them in the refrigerator for up to 5 more days. If you’re looking for broccoli sprout recipes or how to eat broccoli sprouts, then I’ve got you covered too.

FAQs About Sprouting Broccoli Seeds

What is the white fuzz that looks like mold?

You should know that the little fuzzy parts of the sprouts are TOTALLY NORMAL. They’re micro “hairs” meant to help draw moisture into the sprout, and it’s not mold.

That said, you should let your nose tell you if your sprouts have gone moldy. Any kind of sour smell is not normal and means that they’re probably not safe to eat. I’ve only had this happen once in about fifty times, but it can happen.
