Can You Freeze Arugula?

Yes - arugula and rocket are the exact same plant (Eruca vesicaria), just different regional names for it. "Arugula" is the common term in the US and Canada, borrowed from an Italian dialect word, while "rocket" (sometimes "rucola" or "roquette") is standard in the UK, Ireland, Australia, and much of Europe.

Everything in this guide applies equally regardless of which name you know it by - the freezing method, blanching time, and storage windows don't change based on what a region calls it.

You may also see "wild rocket" or "wild arugula" (Diplotaxis tenuifolia) on packaging, a related but botanically distinct plant with narrower, more deeply lobed leaves and an even more peppery bite - it freezes the same way as standard arugula/rocket, though its slightly tougher leaf structure holds up marginally better to blanching and freezing than delicate baby arugula does.

If a recipe or storage guide from a UK source mentions rocket and one from a US source mentions arugula, you're reading about the same vegetable.

Yes, and it's the easiest way to use frozen arugula - there's no real benefit to thawing it first for cooked applications.

Add frozen arugula straight into soups, stews, or pasta sauces during the last few minutes of cooking, where it wilts in almost immediately, similar to how you'd add fresh spinach at the end of a dish.

For sautéing, toss frozen arugula into a hot pan with a little oil or butter - it releases some water as it thaws and cooks, so give it a minute longer than you would fresh leaves, and don't crowd the pan.

If you froze arugula as pesto or a puree, there's even less to think about: scoop out a frozen cube or portion and stir it directly into hot pasta, a sauce, or a dressing, where it thaws and blends in as the dish comes together.

It freezes acceptably for cooked uses, but arugula is one of the more delicate leafy greens on this site, and it shows. Because the leaves are thin with a lot of surface area relative to their volume, freezing ruptures a large proportion of their cell structure, and thawed arugula comes out soft, limp, and notably wilted - there's no getting the raw, peppery crunch back.

Blanching first (a brief 1-minute dip in boiling water, then an ice bath) deactivates the enzymes that would otherwise keep degrading color and flavor during storage, extending good quality to about 6-8 months versus a much shorter window for raw-frozen leaves.

If you want a genuinely better result than whole frozen leaves, blend arugula into a pesto or puree (with olive oil, garlic, nuts, and Parmesan, or even just oil and salt for a simpler puree) before freezing. Pureeing sidesteps the soggy-leaf problem entirely, since you're no longer relying on the leaf structure holding up - you get a concentrated, freezer-friendly product that tastes like arugula rather than a limp, watery version of it.

Either way, frozen arugula is a cooked-dish ingredient from here on - it's not coming back for salads or as a raw garnish.

For whole blanched leaves, a heavy-duty freezer bag with the air pressed out works well - pack the leaves in a flat, thin layer so they freeze quickly and you can snap off portions later without thawing the whole bag.

For arugula pesto or puree, a lidded silicone freezer tray↗(affiliate link, opens Amazon) is genuinely the better option: it portions the puree into measured cubes you can pop out one or two at a time for a single serving of pasta or a quick sauce, rather than defrosting a large block for a small amount of use.

Rigid containers work for either format if you don't need individual portions, but leave a small amount of headspace for pesto or puree, since the oil and water content can expand slightly as it freezes.

Whatever you choose, press out as much air as possible - arugula's thin leaves and any oil-based puree are both prone to freezer burn and oxidation if air gets trapped in the packaging.

Frozen-and-thawed arugula shines wilted into hot dishes: stirred into soups and minestrone, tossed into pasta with olive oil and garlic in the last minute of cooking, folded into a frittata or scrambled eggs, or blended into a warm white bean and greens stew.

Arugula pesto (whether you froze it as pesto or blended thawed leaves into pesto fresh) is excellent stirred into pasta, spread on sandwiches or flatbread, or spooned over roasted vegetables or grilled chicken.

Sautéed arugula, wilted quickly in olive oil with garlic and a pinch of red pepper flakes, makes a simple, fast side dish that hides the texture change well since it's meant to be soft anyway.

Avoid using frozen arugula raw in salads, on top of pizza after baking, or as a fresh garnish - all applications where its peppery crunch and structure are the point, and where the limp, wilted texture of thawed arugula will be an obvious letdown.

A modest one, mostly around timing and toughness. Baby arugula has thinner, more tender leaves with a milder peppery flavor, and it wilts and softens fastest of the three - both fresh in the fridge and once frozen and thawed, so err toward the shorter end of any blanching time given for it (closer to 30-45 seconds rather than a full minute).

Standard mature arugula has slightly heartier leaves and a more pronounced peppery bite; it holds up marginally better through blanching and freezing since there's a bit more structure to lose before it turns fully limp.

Wild arugula (a related but different species, sometimes labeled "wild rocket") has narrower, more deeply lobed leaves and the most intense, almost mustardy flavor of the three - its leaf structure is a touch more robust, so it tolerates the standard 1-minute blanch well and holds its (already assertive) flavor a little longer in the freezer than baby arugula does.

Regardless of type, all three follow the same core method: blanch briefly, shock in ice water, dry thoroughly, and freeze for cooked uses only - the differences are in degree, not in the underlying approach.
