Quick Answer
Yes, it is perfectly OK to use frozen spinach in smoothies. In fact, frozen spinach can be ideal for smoothies because it breaks down easily when blended. Frozen spinach contains the same nutrients as fresh spinach and provides an easy way to boost nutrition in smoothies. Some benefits of using frozen spinach in smoothies include convenience, longer shelf life, and available year-round. As long as the frozen spinach is 100% pure with no added ingredients, it can be a nutritious ingredient for smoothies.
What are the benefits of using frozen spinach in smoothies?
Convenience
One of the main benefits of using frozen spinach in smoothies is convenience. Frozen spinach is pre-washed, pre-chopped and ready to use straight from the freezer. This saves time compared to washing and chopping fresh spinach. It also provides a quick and easy way to add spinach to your smoothie routine. Keeping a stash of frozen spinach on hand means you can make nutritious green smoothies anytime without much prep work.
Longer shelf life
Frozen spinach has a much longer shelf life compared to fresh spinach. When stored properly in the freezer, frozen spinach can keep for 6-12 months. Fresh spinach, on the other hand, only lasts about 3-5 days in the fridge. The freezing process stops the decay process, preserving the nutrients and quality of the spinach. This makes frozen spinach perfect for smoothies because you can store it for longer periods without worrying about it going bad.
Availability year-round
One limitation of fresh spinach is that it goes out of season during hot summer months. However, frozen spinach is available year-round, regardless of what’s in season. This means you can make nutrient-packed spinach smoothies even when fresh spinach is not widely available in your area. The consistent availability provides more options for adding greens to your smoothies no matter the time of year.
Nutrient retention
Many people worry that frozen veggies lose nutrients during the freezing process. However, research shows that the vitamin and mineral content of frozen spinach is comparable to fresh-picked spinach. In some cases, frozen spinach has higher nutrient levels because it is flash frozen at peak ripeness. The quick freezing helps retain the spinach’s nutrients. So using frozen spinach in smoothies provides the same nutrition punch as fresh.
Affordability
Frozen spinach is typically more affordable than fresh spinach. And since the frozen bags contain multiple servings, you get more for your money. Making smoothies with frozen spinach can help you save money while still getting wholesome nutrition from leafy greens. Keep an eye out for sales on frozen veggies to further maximize your food budget.
Smooth, creamier texture
Some smoothie-makers find that frozen spinach leads to a smoother, creamier blended texture compared to fresh leaves. The ice crystals that form during freezing help break down the plant cell walls in the spinach. This releases more liquid that blends into the smoothie for a luxuriously creamy mouthfeel. So if you like your smoothies extra velvety, frozen spinach can help achieve that texture.
More blendable
In a similar vein, the frozen state makes spinach easier to blend in smoothies. Fresh spinach leaves tend to be sturdy and fibrous. But frozen spinach readily incorporates into the smoothie ingredients once blended. The frozen state makes the spinach more breakable and blendable for a smooth drink consistency.
Are there any downsides to using frozen spinach?
While frozen spinach has many benefits for smoothies, there are a couple potential downsides to consider:
Mild flavor differences
Some people notice subtle flavor differences between fresh and frozen spinach. The freezing process can degrade some of the plant compounds that contribute flavor. This can result in frozen spinach having a more muted taste. However, the other ingredients in smoothies typically overpower any flavor differences.
Texture changes when thawed
Frozen spinach has a softer, mushier texture once thawed compared to fresh leaves. The freezing damages the plant cells, changing the mouthfeel. This texture change may be undesirable in some raw applications like salads. But for smoothies, the altered texture makes frozen spinach easier to blend to a drinkable consistency.
Potential added ingredients
Check the packaging to ensure your frozen spinach does not contain any added salt, preservatives or other ingredients. You want to select plain frozen spinach with no flavorings or additives. Added ingredients could diminish the nutritional value for smoothies. As long as you choose pure, unseasoned frozen spinach, it will provide the same benefits as fresh.
Higher sodium content
Some frozen spinach contains higher sodium levels from the blanching process. Blanching helps preserve color, texture and nutrients. But it requires soaking the spinach in saltwater. Look for low-sodium brands of frozen spinach to limit sodium intake from what naturally occurs in the greens. Or rinse the thawed spinach before adding to your smoothie to wash away some excess sodium.
Higher cost for organic
Organic frozen spinach tends to cost more than conventionally grown options. If sticking to an organic diet, you may pay a premium for certified organic frozen spinach. But the extra cost may be worth it to ensure your spinach was grown without synthetic pesticides and fertilizers.
Nutrition comparison of fresh vs frozen spinach
Both fresh and frozen spinach pack a nutritious punch. Here is a nutrition comparison of the two options (based on 100g):
| Nutrient | Fresh spinach | Frozen spinach |
|---|---|---|
| Calories | 23 | 25 |
| Fat | 0.4g | 0.3g |
| Sodium | 79mg | 81mg |
| Carbs | 3.6g | 3.8g |
| Fiber | 2.2g | 2.4g |
| Protein | 2.9g | 3g |
| Vitamin A | 469% DV | 457% DV |
| Vitamin C | 28% DV | 33% DV |
| Vitamin K | 604% DV | 489% DV |
| Folate | 15% DV | 13% DV |
As shown, fresh and frozen spinach have very similar nutrient profiles. Both provide abundant vitamins A, C and K. Frozen spinach contains slightly higher amounts of some nutrients like vitamin C. This small boost may be due to frozen spinach being flash frozen right after harvesting. Overall, the differences are minor – frozen spinach provides the same impressive health benefits as fresh.
How to use frozen spinach in smoothies
Using frozen spinach in smoothies is easy and straightforward. Here are some tips:
Choose plain, unseasoned frozen spinach
Check the package to ensure there are no salt, flavorings or other additives. You want plain frozen chopped spinach with no extra ingredients.
Use partially frozen or thawed spinach
Don’t add frozen spinach straight from the freezer. Allow it to partially thaw for 5-10 minutes first. The partial thawing makes it easier to blend up smoothly.
Add a handful or two
A good rule of thumb is to add 1-2 handfuls of frozen spinach to your smoothie. This provides nutritional benefits without overpowering the flavor. Adjust the amount to your own taste preferences.
Combine with fruit and liquids
Pair the frozen spinach with fruits like bananas, berries or mangos to mask any strong spinach flavor. Use a liquid base like almond milk, coconut water or orange juice to further dilute the taste.
Blend thoroughly
Use a powerful blender and blend for 45-60 seconds to fully break down the spinach, leaving a smooth consistency with no leafy bits. Letting it blend longer yields better results.
Add greens first
Put the frozen spinach in the blender before other ingredients. Adding the liquid and fruit on top helps push the spinach into the blades for proper blending.
Garnish with extras
Once blended, you can garnish with toppings like chia seeds, coconut flakes, cacao nibs or hemp seeds for extra texture and flavor.

Can you use canned spinach in smoothies?
Packaged canned spinach is another alternative to fresh spinach in smoothies. However, canned spinach has some drawbacks compared to frozen:
– Higher sodium content from the canning liquid
– More muted flavor and loss of texture
– Not as readily available year-round compared to frozen
– Shorter shelf life after opening the can
If using canned spinach, look for low-sodium options packed in water. Rinse the spinach before adding to your smoothie to wash away excess sodium. Frozen spinach ultimately provides higher quality nutrition and texture for smoothies. But canned spinach in a pinch can still provide Popeye power!
Should you cook or steam frozen spinach before adding to smoothies?
Cooking or steaming frozen spinach before adding it to smoothies is not necessary. Blending does a good job of breaking down the frozen spinach to a smooth consistency without any cooking required.
Here are some reasons you don’t need to pre-cook frozen spinach:
– No food safety concerns: Frozen spinach is commercially processed for safety.
– Blending helps break down cell walls: The mechanical action releases nutrients and softens the spinach.
– Added heat may degrade nutrients: Heat from cooking can potentially damage certain antioxidants and phytochemicals.
– Raw spinach provides more enzymes: Cooking decreases levels of some enzymes and heat-sensitive nutrients.
– Simplifies your smoothie-making: Skipping cooking means fewer dishes and steps.
Unless you have a personal preference for pre-cooked spinach, adding frozen spinach straight to smoothies is an easy, safe and nutritious option.
Should you microwave frozen spinach before adding to smoothies?
You also don’t need to microwave frozen spinach prior to adding it to smoothies. Microwaving can create hot spots that damage some sensitive nutrients. It also adds extra time and effort without significant benefits.
Here’s why you can skip microwaving frozen spinach for smoothies:
– No food safety improvement: Frozen spinach is safe eaten raw.
– Alters taste and appearance: Microwaving may create a dull green color and odd flavor.
– Makes spinach more mushy: Microwave heat further breaks down the spinach texture.
– Decreases vitamin C content: Some vitamin C loss occurs with microwaving’s heat.
– Blending does the work: Blending properly mixes in frozen spinach without microwaving.
If you want to thaw frozen spinach to room temperature before blending, letting it sit out for 5-10 minutes works well. But microwaving to hot temperatures is not necessary for safe and nutritious spinach smoothies.
Do you need more fresh fruits/veggies if using frozen spinach?
Using frozen spinach in place of fresh spinach does not require you to add extra fruits or veggies to your smoothie recipe. Frozen spinach provides the same nutritional benefits as fresh, so you can use an equivalent amount.
A few tips on fruits and veggies when using frozen spinach:
– Use frozen spinach in the same quantity as you would fresh leaves. No need to adjust the amounts.
– Include fresh fruits to mask unfavorable frozen spinach flavor or texture. Bananas, mangos and berries work well.
– Rotate between frozen and fresh produce to vary nutrients and prevent boredom.
– Make sure your smoothie contains a balance of fruits and veggies as needed for fiber, vitamins and minerals. Frozen spinach contributes to your daily produce needs.
– Add extra fruits like avocado for creaminess if desired, but it’s not mandatory when using frozen spinach.
In short, you can swap an equal amount of frozen spinach for fresh without worrying about modifying quantities of other ingredients. Use your regular smoothie recipe and simply replace the fresh spinach with frozen.
Do you need more liquid if using frozen spinach in smoothies?
Frozen spinach contains ice crystals that blend into liquid, so you typically don’t need to add extra liquid to your smoothie recipe when using frozen spinach. However, here are some tips on managing liquid:
– Start blending your frozen spinach smoothie with less liquid than usual. Then adjust consistency as needed while blending. The frozen spinach provides some liquid once broken down.
– If using partially thawed frozen spinach, you may not need much added liquid beyond the fruits and veggies. The spinach releases moisture during thawing.
– Don’t over-blend or leave spinach chunks too long at room temp or they’ll melt into mush rather than integrating smoothly.
– If your smoothie consistency seems too thick, drizzle in more milk, yogurt, juice or water while the blender runs until reaching the desired thinness.
– Use high-speed blenders for smoothest consistency and avoid adding excess diluting liquid. Slow blenders may require more added liquid.
So monitor the thickness and adjust liquid gradually if your smoothie seems too dense. But avoid pouring in lots of extra liquid upfront since frozen spinach blends into a nice liquid base.
