Even when following all the top tips on how to store fresh asparagus, it is only going to last you about 5 days. When combined with its short peak season, I’ve found that freezing asparagus is the perfect way (other than pickling!) to enhance its shelf life, avoid waste, and make the most of this vegetable practically year-round. Unfortunately, just shoving the spears in a freezer bag and calling it a day isn’t going to cut it. However, following a simple method for blanching, you can preserve the color, texture, flavor, and nutritional value of the veggie. It will be perfect for adding to casseroles, risotto, pasta, stir-fries, and more.

How to prepare fresh asparagus for breezing

It’s important to start with fresh produce before we learn how to freeze asparagus. Look out for stalks that are firm, smooth, and stand upright (not limp/wilting). They should also be a rich green color at the top (unless you’re using white or purple), with no mush/mold. Asparagus peak season is Spring, best between April/ May. The first step is to trim the woody ends of the stalks. First, bend the bottom of a stalk until it snaps. Then line up the ends of a handful of spears on a cutting board and use a chef’s knife to trim the same amount from them all. Repeat with the remaining spears. If your stalks are particularly wide, they may also have a tough peel on the stalk, so feel free to use a vegetable peeler to peel it. This isn’t necessary for small/medium stalks. Meanwhile, bring a large pot of water (lightly salted if preferred) to a boil. Once boiling, carefully lower the asparagus into the water using tongs or a slotted spoon. Alternatively, you can steam-blanch the veggie by placing a steaming basket in a large pan with a lid and cooking it for 3-6 minutes based on its thickness.

How Long to Blanch Asparagus Before Freezing?

The time to blanch depends on its size/thickness. For very thin spears, 1-1:30 minutes is enough. For medium spears, 2 minutes should work great. And, for large/extra-large spears, I recommend 3-4 minutes. It is ready when it has a bright, vibrant green color with a crisp-tender texture. Once the time is up, use tongs to transfer the asparagus to an ice bath (large bowl of ice water) to halt the cooking process. Allow it to sit in the water for about 5 minutes or until entirely cooled. Once cool, transfer to a clean kitchen towel to drain and carefully pat the spears dry. If wanted, now is the time to cut them down into smaller 1-2-inch pieces.

How to freeze asparagus

First, spread the blanches spears across a large baking sheet in a single layer, ensuring they aren’t touching. Then transfer the tray to the freezer to flash freeze for 1-2 hours until they’re solid. This step ensures they won’t stick together when frozen, so it’s easy to thaw only as much as you need each time. Finally, transfer the spears to an airtight container or freezer bag (push as much air out as possible then seal).

Can you freeze asparagus raw without blanching it

Technically, freezing fresh asparagus is possible by placing them directly into the freezer-safe container. However, I wouldn’t recommend it as blanching asparagus is essential for several reasons:

How long can you freeze asparagus for?

You can store blanched fresh asparagus in the fridge for 3-4 days after blanching. Alternatively, the frozen veg will store in the freezer for between 6-8 months for the best quality (flavor and texture), though it technically lasts up to 12 months.

How to use frozen asparagus

There’s no need to defrost frozen asparagus before cooking it (yay!). I love to throw it directly into dishes in the last few minutes of cooking on the stove or before baking them. Because the frozen spears will become tender upon cooking, I prefer using them in recipes where the tender texture works well. I.e., creamy asparagus soup, stews, casseroles, vegetable stir-fries, one-pot pasta bakes, risotto, quiche, etc. To cook just the frozen asparagus. My preferred method is to add it to a pan and sauté the asparagus with a little olive oil or butter for just 1-2 minutes (depending on its size) until tender and hot-through.
