Do you love brussel sprouts but don’t have the time to properly prepare them during the week? Creating your own freezer stash of ready to cook frozen brussels is an edible insurance policy for fast and healthy side dishes.

I have a thing for brussel sprouts. See: Honey Sriracha Brussel Sprouts, Air Fryer Frozen Brussel Sprouts, Roasted Frozen Brussel Sprouts, and Air Fryer Brussel Sprouts.

And now, this tutorial on how to freeze brussel sprouts is giving us even more veggie goodness.

And if brussel sprouts aren’t your jam, consider adding cheese to them. Check out our Gluten-Free Cheese Sauce for the easiest cheese sauce ever!

Can You Freeze Brussel Sprouts?

Absolutely! This hardy vegetable is a great candidate for the freezer. When properly prepared, frozen brussel sprouts can be stored in the freezer for 6-12 months. 

Can You Freeze Fresh Brussel Sprouts Without Blanching?

Yes (and also no). It depends on how quickly you’d like to use them. If you plan to use the frozen sprouts within a few weeks, there is no need to blanch them first.

For long-term freezer storage, pre-cooking them helps to retain vitamins and nutrients and also preserves the color. Unblanched brussels will be mealy and grainy when defrosted or cooked.

Blanching also helps to lock in the flavor and keeps everything safe for long-term preservation. Thankfully it is an easy process and will take you less than 10 minutes.

Frozen Brussel Sprouts Equipment

You’ll need a saucepan or dutch oven, a slotted spoon, and a mixing bowl that you can fill with ice and water.

You’ll freeze brussel sprouts on a rimmed baking sheet lined with parchment, a silpat, or waxed paper. Once frozen, transfer to freezer storage (we love these reusable silicone bags for freezing items. Use “sustainablecooks15” for 15% off).

How to Reheat Frozen Brussel Sprouts

In most cases, you can cook the sprouts directly from the freezer. My favorite way to use frozen brussels is to roast them. You can read more about it in this guide on How to Roast Frozen Vegetables.

Preheat the skillet you’re using (or the air fryer) to make sure that the frozen sprouts start cooking as soon as they hit the skillet/air fryer basket. This will roast them instead of steaming them while they slowly heat up in a cold oven/air fryer.

Pro Tips/Recipe Notes

  • There is no need to thaw the frozen brussel sprouts before cooking them.
  • Freeze in portions you plan to use upon defrosting. Quart freezer bags will replace a 15 oz bag from the store.
  • Frozen brussel sprouts will last in a conventional freezer for six months. If you have a deep freeze/stand-alone freezer, you’re safe to keep them in there for up to a year.
