I’ll show you how easy it is to grow broccoli sprouts right on your kitchen countertop. Best of all, there’s no dirt required! Growing broccoli sprouts at home is as easy as these five steps:

Soak the seeds overnight.
Transfer the seeds to a sprouting vessel and place in a dark, well-ventilated room.

Harvest the broccoli sprouts once they reach the desired length after about 4-5 days.

My Experience Growing Broccoli Sprouts:

My interest in growing broccoli sprouts started back in 2012 with this 2-minute video from NutritionFacts.org. The title is “Biggest Nutrition Bang for Your Buck” where Dr. Michael Greger states that “growing your own broccoli sprouts is one of the most cost-effective ways to improve one’s diet.” Wowsa! How could this admitted health-food junkie pass on a statement like that?

My Step-by-Step Guide for How to Grow Broccoli Sprouts at Home:

Dr. Greger advises 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 Victorio sprouter (updated with BPA-free plastic and 4 trays).

The sprouter kit came with alfalfa seeds, but I passed on those and used organic broccoli seeds from my friends at NOW Foods:

I am so mechanically un-inclined that I was a little nervous about screwing up the sprouter, but it really wasn’t that hard to figure out and the guide from Victorio was very helpful and easy to follow. I soaked my seeds overnight in a bowl of water and strained them before placing a tablespoon of the seeds on each tray:

The directions have you “washing” the seeds twice a day. Using the sprouter, that simply means to pour more fresh water into the top tray and let it siphon down to the bottom reservoir (you will see how this works if you have your own. It’s easy: I promise!). I was like a kid doing my first science experiment when I discovered the seeds actually sprouted the next day:

I think it might take up to 5 days to get fully-grown sprouts, but here’s how they looked this morning after 48 hours:

All up close and personal:

I moved them to a slightly lighter part of the kitchen to see if that helps along the process, although the directions say they shouldn’t be in direct sunlight.

Also, 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.
