Can You Freeze Rhubarb?

Directions for Freezing Rhubarb

Step 1 - Clean and Dry the Rhubarb

The very first step is to clean the rhubarb. Rinse the stalks well under running water. If you use a vegetable cleanser (side note: did you know that rhubarb is a vegetable?) and brush, go ahead and use them to get the stalks super clean.

Next, dry the rhubarb well. You can do this by laying the stalks on paper towels and pressing them with another paper towel on top, or you can use a clean kitchen towel.

Why do you dry them off? Because excess moisture creates freezer burn, which damages the texture and flavor.

Step 2 - Slice the Rhubarb

Place a rhubarb stalk on a cutting board so that it's facing you horizontally. Then take a sharp knife and slice it from end to end, tossing the very end of the stalk out.

If there's a green leafy part still intact, make sure you cut that away, too. Continue slicing this way for every rhubarb stalk.

How thick you make the slices depends on your personal preference. If you're not sure, a good rule of thumb is generally about an inch thick or a little less.

Step 3 - Flash Freeze the Rhubarb Slices

Take a baking sheet that will fit in the freezer and line it with parchment paper or wax paper. If you have a nonstick tray, that'll work just fine on its own.

Spread the rhubarb slices out on the baking sheet so that they're not overcrowded. Then put the tray in the freezer for up to a couple of hours, or until the rhubarb is frozen solid.

This is a neat trick to get the rhubarb to freeze without clumping together in one big mess that you'll struggle to separate down the road.

Step 4 - Put the Rhubarb in Freezer Safe Containers

When the rhubarb slices are frozen all the way through, it's time to put them into a freezer-safe container, making sure to fill it all the way to remove excess air.

Another great way to freeze is to use plastic freezer bags. These will make it super easy to get all the air out, and the bags will probably take up minimal space in the freezer.

There you have it! Perfectly frozen rhubarb for pies, jams and anything you like.
