Can you freeze rhubarb?

If you’re swimming in produce from your garden, farmers’ market, or CSA, you may be wondering:

  • Can you freeze rhubarb?
  • Okay, but does it freeze WELL?
  • In what kinds of recipes can you use it?

Great news, friends. Rhubarb is a prime candidate for freezing. It’s easy to freeze, it holds up great in the freezer, and you can use it in virtually all cooked recipes that call for fresh.

Here’s how to do it.

How to do it

It only takes five minutes to prep this veggie for the freezer. Here’s what you’ll do.

chopping and prepping rhubarb to freeze
  1. Prep the stalks. Remove any leaves (which are poisonous) and wash and dry the stalks well. Trim and discard the ends. Then slice the stalks into segments. Half to one inch is a great all-purpose size. Or prep according to specific recipes if you know what you’ll be making.
  2. Line a rimmed half-sheet pan with parchment.
  3. Spread the pieces evenly over the prepped pan, without crowding. One pound fits perfectly on a half-sheet pan. Freeze until solid, about 24 hours.
  4. Transfer the frozen segments to a sealable freezer bag or reusable container. Keep frozen for up to a year to use in your favorite recipes.

Expert tips and FAQs

How long does frozen rhubarb keep?

You can easily keep it for up to a year, after which you’ll have a whole new crop.

What kinds of recipes can I use it in?

The great news here is that you can use frozen rhubarb in virtually any recipe that calls for fresh (as long as there’s cooking or baking involved). See the section below for our favorite ways to use it.

Do you have to blanch rhubarb to freeze it?

Blanching is boiling very briefly and then plunging into cold water. You really do not have to blanch this vegetable before freezing.

Can I freeze fresh rhubarb raw?

You sure can. Just wash, dry, and cut into segments as detailed in the post for ease of use.

Is frozen rhubarb as good as fresh?

When using it in cooked recipes, we find that frozen is just as good as fresh. Like most fruits and veggies, this one gets very soft when thawed, but you can add it to recipes without thawing it first. You may need to add a few minutes to the cooking or baking time, depending on the recipe, but should not need to make any other changes.

Should I thaw frozen rhubarb before baking?

Nope, you don’t have to! And in fact we don’t recommend it. It gets soft when thawed, so it’s easier to work with frozen.

Can I freeze stewed rhubarb?

Yes, you can! If you’d rather not freeze it raw, you can also make our sauce/compote and freeze that.

How to use it

The great news is that you can use it in pretty much any recipe that you’d use fresh. Here are our favorites:
