Can You Freeze Arugula? The Short Answer
Yes, you can freeze arugula! However, the texture and taste may change during the freezing process. Fresh arugula can become limp after thawing, making it unsuitable for salads but perfect for cooked dishes, smoothies, or pestos.
The Freezing Process: Step-by-Step Guide
Freezing arugula requires careful preparation to maintain the best quality. Here’s a step-by-step guide to ensure you freeze your arugula correctly.
Step 1: Harvesting and Cleaning
If you’re harvesting arugula from your garden, make sure to pick only the freshest and healthiest leaves. If you’re using store-bought arugula, check for any signs of spoilage.
- Rinse the arugula leaves thoroughly under cold water to remove any dirt or insects.
- Drain the leaves in a colander to remove excess water.
Step 2: Blanching the Arugula
Blanching is a crucial step when freezing arugula. This process helps to preserve the vegetable’s color, texture, and nutritional value.
- Bring a pot of water to a rolling boil.
- Prepare an ice bath by filling a large bowl with ice water.
- Once the water is boiling, add the arugula and blanch for 30 seconds.
- Immediately transfer the arugula to the ice bath to stop the cooking process.
- Once cooled, drain the leaves again.
Step 3: Drying and Packing
It’s important to remove as much moisture as possible before freezing, as excess water can lead to freezer burn.
- Pat the arugula dry with a clean kitchen towel or paper towel.
- Place the arugula in a single layer on a baking sheet.
- Freeze the leaves for 1–2 hours until they are firm.
- Once frozen, transfer them into airtight freezer bags or containers.
Storage Tips
Make sure to label your bags or containers with the date of freezing to keep track of freshness. Ideally, frozen arugula can last up to 6–12 months in the freezer.
Using Frozen Arugula

Can arugula be frozen raw?
Yes, arugula can be frozen raw, but it may not retain its best texture or flavor once thawed. Freezing fresh greens like arugula typically results in a change in their texture, making them more wilted and softer. If you enjoy arugula in salads or fresh dishes, freezing it raw may not yield the best results for your desired use.
If you still choose to freeze raw arugula, it’s essential to wash and dry the leaves thoroughly before placing them in an airtight container or freezer bag. This will help reduce freezer burn and preserve the quality of the greens to some extent. However, keep in mind that the best way to utilize frozen raw arugula is by incorporating it into cooked dishes, such as soups or stir-fries.
Should I blanch arugula before freezing it?
Blanching arugula before freezing is highly recommended as it helps preserve the flavor, color, and nutrients of the greens. Blanching involves briefly boiling the leaves and then rapidly cooling them in ice water. This process stops enzyme actions that can cause a decline in quality during storage. Blanching also helps reduce the bitterness often associated with raw arugula.
To blanch arugula, bring a pot of water to a boil and prepare a bowl of ice water. Submerge the arugula leaves in boiling water for about 1-2 minutes, then quickly transfer them to the ice water to cool. Once cooled, drain them thoroughly on a clean kitchen towel or colander and pack them into airtight containers or bags before freezing. This method often results in better texture and flavor when the arugula is thawed.
How long can frozen arugula last?
Frozen arugula can last up to 6-12 months in the freezer when stored properly. However, for the best taste and quality, it’s recommended to consume it within the first 3-6 months. Over time, even frozen foods can develop freezer burn, which can affect the taste and texture of the greens.
To maximize the shelf life of frozen arugula, ensure that it is kept in an airtight container or vacuum-sealed bag. Label the packages with the date of freezing, so you can keep track of how long they’ve been stored. Regularly checking your freezer for any signs of freezer burn or spoilage will help you use your frozen greens at their best.
What is the best way to store arugula in the freezer?
The best way to store arugula in the freezer is to first wash, dry, and blanch the greens. After blanching, quickly cool the leaves using an ice bath, then drain them well to remove excess moisture. This prevents ice crystals from forming and preserves the quality of the arugula during freezing.
Following the drying process, pack the arugula into airtight freezer bags or containers. Remove as much air as possible from the bags to prevent freezer burn. Finally, label the bags with the date and store them flat in the freezer for easy stacking and access.
Can frozen arugula be eaten raw after thawing?
Frozen arugula is generally not recommended for eating raw after thawing, as the freezing process alters its texture. When thawed, the leaves tend to be limp and may be unappealing in salads or fresh dishes. Instead, it’s better to use thawed arugula in cooked recipes where the texture change is less noticeable.
However, if you enjoy experimenting, you can try adding thawed arugula to smoothies or pureeing it into soups or sauces. While the texture may not be ideal for fresh consumption, using thawed arugula in blended forms can still provide its unique flavor and nutritional benefits.
Can I freeze arugula that has already been dressed?
It is not advisable to freeze arugula that has already been dressed with vinaigrette or any other dressing. Freezing dressed greens can result in a mushy texture and lead to a change in flavor once thawed. The acids and oils in dressings can also affect how the greens freeze and thaw, making them less palatable.
If you want to save leftover dressed arugula, it’s best to consume it within a few days rather than freezing it. Alternatively, consider freezing plain arugula and dressing it fresh after thawing if needed.
Can I use frozen arugula in smoothies?
Yes, frozen arugula can be an excellent addition to smoothies! When added to a blender, the texture of the frozen greens typically becomes smooth and blends well with fruits, yogurt, and other smoothie ingredients. Freeze-dried arugula offers a convenient way to incorporate nutrients and an earthy flavor into your smoothie without worrying about spoilage.
Before using frozen arugula in smoothies, you can decide whether you want to thaw it slightly or use it directly from the freezer. If you choose to thaw, just leave it at room temperature for a few minutes, so it softens a bit. This can help ensure your smoothie maintains a nice, drinkable texture without being overly thick.
How can I tell if frozen arugula is still good to use?
To assess if frozen arugula is still good to use, begin by checking the packaging for any significant signs of freezer burn, such as ice crystals forming on or inside the bag. While freezer burn doesn’t make food unsafe to eat, it can significantly reduce the taste and quality of the greens. If the arugula smells off or has changes in color or texture, it’s best to discard it.
Additionally, if you notice any significant changes in flavor or an unpleasant odor when you cook or blend thawed arugula, that might be an indicator that it has gone bad. Always trust your senses when evaluating the quality of frozen food. If in doubt, it’s better to err on the side of caution and not consume the product.
