What’s the best thing to freeze smoothies in?

Smoothies make for a delicious and nutritious on-the-go breakfast or snack. The beauty of smoothies is that you can prep them in advance, which makes your mornings that much easier. But in order to enjoy smoothies throughout the week, you need to know the best vessel for freezing them.

Freezing smoothies allows you to batch prep multiple servings at once. This saves you time and lets you pull together customized smoothies using your frozen, pre-portioned ingredients. But not all containers are created equal when it comes to freezing smoothies.

The ideal smoothie freeze container should be airtight, freezer-safe, BPA-free, easy to stack, and portion-friendly. With the right freezer containers, you can whip up smoothie pops, cubes, and ready-to-blend bags so you can enjoy fresh, homemade smoothies whenever you want.

Plastic Containers

Plastic containers are a popular choice for freezing smoothies. However, not all plastics are created equal. You’ll want to choose plastic that is:

  • BPA-free – BPA is a chemical found in some plastics that can leach into foods. Look for BPA-free plastic containers.
  • Freezer-safe – Not all plastics can withstand freezing temps without cracking or warping. Opt for freezer-grade plastic.
  • Airtight – A tight seal is crucial to prevent freezer burn and oxidation.
  • Stackable – Stackable containers save freezer space.
  • Portion-friendly – Look for pint, quart, or cup sizes that hold 1-2 servings.
  • Durable – Choose thick, durable plastic that won’t easily crack when dropped.

Ideal Freezer Temps for Smoothies

To maintain quality, smoothies should be frozen at a steady 0°F. Temperature fluctuations can cause icy crystals to develop. Here are some tips for proper freezing:

  • Set your freezer to 0°F if possible
  • Avoid opening the freezer frequently
  • Fill any empty space in your freezer with bags of ice to maintain consistent temps
  • Don’t overstuff your freezer, air needs to circulate
  • Position smoothies towards the back of the freezer where temps are most stable

How Long Do Smoothies Last in the Freezer?

When frozen properly at 0°F, smoothies can last 6-12 months in the freezer before quality decreases. Here are some signs your frozen smoothie has expired:

  • Ice crystals, freezer burn spots, or dried out texture
  • Separation when thawed with water leaching out
  • Off odors, usually from oxidation
  • Change in color, especially greens becoming brown
  • Mold spots on fruit

For best quality and nutrition retention, aim to consume frozen smoothies within 6 months.
