Can You Freeze Spinach?

Yes, freezing fresh spinach is easy and keeps it fresh and nutritious. It’s a handy way to make it last longer and use it in many dishes.

Freezing Spinach for Smoothies

Like adding spinach to smoothies? Try freezing it as a puree. Just blend spinach with a bit of water until smooth. Then, pour it into ice cube trays or silicone muffin tins. After freezing, put the cubes into a freezer bag or container. This lets you use just the right amount for smoothies anytime.

Freezing Spinach for Cooking

When using spinach in cooked recipes, blanch it first. Blanching keeps the spinach’s texture and color nice. Just boil water, dunk the spinach for 1-2 minutes, and then cool it in ice water. Squeeze out extra water and put the spinach into freezer bags or containers.

Proper Storage

Use airtight bags or containers when freezing spinach. This avoids freezer burn and keeps moisture out. Always label with the freezing date. Properly stored, frozen spinach stays good for 8-12 months.

Thawing Frozen Spinach:

  • For refrigerator thawing: Put the spinach in the fridge to thaw overnight. Use it in cooked dishes like casseroles or soups.
  • For cooking with frozen spinach: Just add it to your dish as it cooks. The heat will thaw the spinach right in the pan.

Tips for Preserving Spinach

Keeping spinach fresh is easy with a few steps. These tips help your spinach stay green and tasty.

Step 1: Inspect and Prepare

First, look over the spinach and take out any bad leaves. This stops the rest from going bad.

Remember: One bad leaf can spoil the whole bunch!

Step 2: Dry Thoroughly

To maintain freshness, you must dry spinach well. Wash the leaves gently, then let them air dry. Or, use a salad spinner.

Next, wrap the spinach in paper towels to soak up extra water. Keeping it dry avoids sliminess and spoilage.

Step 3: Proper Storage

Storing spinach the right way means keeping it cold and dry.

Use airtight containers or bags for storage. Ensure they’re sealed well to keep air and moisture out.

Store in the fridge’s crisper drawer for best results. This keeps it cold and slows spoilage.

For plastic containers, choose ones with air holes. Or pick bags made for greens. This prevents moisture buildup.

Step 4: Washing and Drying Considerations

It’s usually best to store spinach unwashed for longer freshness. If you need to wash it, dry it completely after.

Use the paper towel method to dry your spinach well. Place dry leaves on lined paper towels in a container or bag. This method helps keep spinach crisp.

Step 5: Regular Checks

Check your spinach often. Look for spoilage signs like discoloration or bad smell.

Spotting spoilt spinach early can prevent cross-contamination and keep the rest of your stored greens safe to eat!


Preserving spinach right involves checking, drying, and storing carefully. By removing spoiled leaves, drying well, using the right containers, and checking often, you can keep spinach fresh longer. Enjoy its health benefits for more time.
