Frozen Broccoli Cubes

This was a recipe created out of necessity after my neighbor brought me a huge bag of broccolini that I didn’t know what to do with. So, after doing a little research on the web, I decided to steam and puree the broccoli into frozen broccoli cubes that I could just pop into my next green smoothie or healthy soup. 

Here’s how to freeze broccoli into Frozen Broccoli Cubes.

Recipe Steps

Step One

The first step in making broccoli cubes is to steam and chill the broccoli. I steamed the broccoli in my steamer basket on the stovetop, but you can also do it in the microwave.

Step Two

The next step after you steam the broccoli is to put it into an ice water bath to cool it down. This will help preserve the lovely green color of the cooked broccoli.

Step Three

After steaming and chilling the broccoli to keep it from over-cooking, I then recommend pureeing it to make into cubes. Of course, if you don’t want to puree your broccoli, then you could just freeze it at this point. 

To freeze the broccoli instead of pureeing it, you would just lay it onto a parchment-lined baking sheet and freeze for at least an hour before transferring it to a zip-top bag for long-term storage.

Step Four

To puree the steamed broccoli, you only need to process it for about 30 seconds on high.

Step Five

Then, the second-to-last step is to pour that beautiful green puree into ice cube trays. I used these silicone ice cube trays I bought online.

Step Six

Finally, after the broccoli cubes are frozen solid, you can then transfer them into zip-top bags for long-term storage.

FAQs

How do you use broccoli cubes?

I often add them to my green smoothies. Once they are blended with fruit and all the other ingredients, you can’t even taste the broccoli! This Strawberry Green Smoothie would be a great recipe to use your broccoli cubes in.

If you don’t want to add your frozen broccoli cubes to a smoothie, you can also add them to a soup or stew to add extra veggies and fiber.

Can I leave out the lemon?

Yes, I think it helps mask any bitterness to the broccoli, but you can leave it out.
