Growing sprouts in a mason jar is a straightforward and inexpensive way to grow your own sprouts in your kitchen.

In these directions we use the word ‘seed’, this includes all seeds, beans and lentils. We don’t recommend sprouting Chia in a jar, use a hydroponic pad or a terracotta sprouter instead.

One Tbsp of seed makes approximately one cup of sprouts, depending on the variety.

Equipment List

  1. 1 Quart glass mason jar
  2. Mason jar lid with rinsing screen (BPA free plastic or stainless steel)


  1. Muslin fabric and an elastic band or food grade string to secure it.
  2. A dish rack to drain the jar or a mason jar draining rack


  1. Make sure your mason jar is clean and you have the lid ready to attach.
  2. Rinse your seeds under cold water and put them in the jar.
  3. Add plenty of cold water to the jar so the seeds are covered and put the lid on/secure the muslin.
  4. Allow the seeds to soak for 24 hours in the jar.
  5. Drain the ‘soaking’ water out of the jar.
  6. Add fresh, cold water and rinse the seeds, pouring the excess water out of the jar.
  7. Invert the jar so it is upside down, at an angle so the water can continue to drain. Make sure there is no standing water in the jar. Use a dish draining rack or a mason jar rack to prop up the jar.
  8. Continue to rinse and drain the seeds twice a day (morning and evening.)
  9. Depending on the variety of seed, small sprouts will appear in a day or so. You can eat them as soon as they start to sprout or wait a few days until they leaf out and have a couple of small leaves.
  10. If the leaves are not green enough, put the sprouts in a sunny spot for a an hour or so, but don’t let them dry out.
  11. When the sprouts are ready, take them out of the jar, drain any excess water and store them in the fridge just like any other salad.
