Starting in late May, I make a Strawberry Rhubarb Crisp at least once a week. It’s a great dessert, and let’s be honest, you can easily convince yourself that fruit + oats make for a solid breakfast the next day.

Rhubarb season is way too short. If you want to enjoy it for longer than six weeks each year, freezing your own is definitely the way to go. And unlike canning, freezing requires zero special equipment or skills. If you can put a tray into a freezer, you can do this!

Can You Freeze Rhubarb?

Yes! The growing season is very short, so having chopped frozen rhubarb as part of your freezer essentials can make your meal prep a breeze.

When you freeze things in a single layer on a baking sheet, this is called flash-freezing. Flash freezing basically allows each piece of rhubarb to freeze separately. This will allow them to be stored together without being frozen in one big clump.

Need 1 cup for a recipe? You can easily just scoop it out of your freezer bag without having to hack at a big chunk.

Can I Freeze Rhubarb Raw?

Yes, but only if you plan to use it with two months. If you want to keep the rhubarb in the freezer longer, it is best to blanch it before freezing.

Thankfully, it’s super easy to blanch rhubarb. You’ll just need to bring a pot of water to a boil, add the rhubarb, and cook for 60 seconds. Scoop the slices out with a slotted spoon and put into a bowl with ice water. THAT’S IT.

How to Use It

Rhubarb is great for more than just fruit crisps and pies! You can add some to Low-Sugar Strawberry Jam for a delightful strawberry/rhubarb spread. Finely chop some and add it to this Strawberry Syrup or Strawberry Puree to pour over whole wheat pancakes, whole grain waffles, or Instant Pot Cold Start Yogurt.
