How to Store Arugula: Do not wash arugula until you are ready to eat it. Wrap the leaves loosely in dry paper towels to absorb excess moisture, then place them in a hard container (to prevent crushing) or a Ziploc bag with a little air inside. Store in the crisper drawer. This method helps keep it fresh for 7 to 10 days.
Food Safety Tip: Arugula grows close to the ground. Always wash thoroughly before consuming to remove sand and soil, but only wash right before your meal.
The “Diva” of Salad Greens
If iceberg lettuce is the sturdy workhorse of the salad world, arugula (or rocket) is the absolute diva. One minute it is perky and peppery, and the next minute, literally overnight, it turns into a wet, dark green sludge at the bottom of the bag. It is frustrating to buy a plastic clamshell for $5 only to throw half of it away.
Unlike when you store iceberg lettuce, which has a thick structure, arugula leaves are incredibly tender. They bruise easily and “breathe” heavily, creating their own moisture that eventually drowns them. Over the years, I have learned that treating arugula more like you would store fresh herbs (with gentle hands and humidity control) is the secret to longevity.
Don’t give up on this delicious green! With a simple roll of paper towels and the right container, we can double its lifespan.
The Science: Why Arugula Rots
To keep arugula fresh, you have to fight against its own biology. According to the Virginia Tech Food Science department, leafy greens have very high respiration rates.
- Respiration & Moisture: Arugula “exhales” water vapor. In a sealed plastic bag, this water condenses on the leaves. Since the cell walls are thin, this standing water encourages bacteria to break them down, causing slime.
- Compression: Because the leaves are so delicate, jamming them into a drawer crushes them. Damaged leaves release enzymes that speed up decay for the whole bunch. This is why hard containers often work better than bags.
- Ethylene: Like most greens, it is sensitive to ripening gas. Keep it away from bananas or when storing tomatoes.
Visual Glance: The Shelf Life
Arugula has a shorter clock than hardy greens like kale. Here is what to expect.
Comparing it to other salads, arugula is much more fragile than when you store romaine lettuce. If you mix them in a salad, the arugula will always spoil first, so I recommend storing them separately until serving time.
Storage Method Showdown
I tested these methods in my own fridge. The difference between “edible” and “sludge” was just one paper towel.
Video Guide: The Paper Towel Trick
Keeping it Green
This video demonstrates the most effective way to store delicate greens like Rocket (Arugula). The key is absorption.
The Technique: You don’t need to wash it first if it’s pre-washed. Just layer it with paper towels to wick away the moisture it breathes out. If you do wash it, ensure it is bone dry, a salad spinner is mandatory.
As noted by University of Maine Extension, reducing surface moisture is the best way to prevent bacterial growth.
Interactive Storage Chart
Filter by the type of arugula you bought. Those plastic clamshells need help!
| Type | Container | Freshness | Key Tip |
|---|---|---|---|
| Baby Arugula (Box) | Add Paper Towel | 7-10 Days | Flip container daily to redistribute water. |
| Wild Bunch | Damp Towel on Stems | 5-7 Days | Treat stems like herbs, keep leaves dry. |
| Arugula Pesto | Freezer | 6 Months | Best way to save wilting greens! |
| Unopened Bag | Original Bag | 3-4 Days | Leaves crush easily; move to box if possible. |
| Dressed Salad | Bowl | 12 Hours | Acid (vinaigrette) cooks leaves instantly. |
Safety: The Slime Test
Arugula goes bad quickly and obviously. Referencing Nutrition.gov, check these signs:
- ⚠️ Wet Sludge: If the leaves have turned dark green, wet, and gooey, throw them out. This is bacterial decay.
- 👀 Yellowing: Yellow leaves are old and will taste bitter, but they aren’t necessarily unsafe if dry. Pick them out.
- ⚠️ Sour Smell: Arugula should smell peppery or neutral. A sour or “swampy” smell means it’s garbage.
Arugula Myths Busted
Let’s clear up some kitchen folklore:
- 🚫 Myth: You can freeze leaves for salad. Reality: No. Arugula is too delicate. It will thaw into green slime. Only freeze it if you plan to blend it into pesto or soup, similar to storing kale for smoothies.
- 🚫 Myth: Washing extends life. Reality: Moisture kills arugula. Only wash right before eating.
Reviving Wilted Arugula
If your arugula is looking a bit sad and droopy but hasn’t turned slimy yet, you can shock it back to life. Submerge the leaves in a bowl of ice water for 10-15 minutes.
The cold water rehydrates the leaves. Spin them bone-dry in a salad spinner immediately. This works for many tender greens, just like the trick for lettuce storage.
Having the right storage tools makes saving delicate greens easy. Here are my top picks.
Leakproof Containers
Hard-sided containers protect arugula from getting crushed in the drawer.

Arugula lasts 3 to 5 days in the fridge when stored unwashed in a loose bag with a dry paper towel. Kale is far sturdier than arugula and can last up to 7 to 10 days in the fridge using the same method. Swiss chard is another delicate leafy green with a similar 3 to 5 day fridge window and needs the same paper towel and bag method as arugula. Heartier salad leaves like iceberg lettuce stay crisp for up to 2 weeks in the fridge, making it a much longer-lasting option than arugula.
