How do you freeze raw carrots?


Freezing carrots is a great way to preserve fresh carrots for future use. Frozen carrots maintain many of the nutrients found in fresh carrots, and they can be easily stored in the freezer for months. Freezing works well for all types of carrots, including whole carrots, diced carrots, and even carrot sticks. With a few simple preparation steps, you can freeze large batches of carrots to have on hand whenever you need them. In this comprehensive guide, we will cover everything you need to know about successfully freezing raw carrots at home.

Benefits of Freezing Carrots

There are several advantages to freezing carrots rather than relying solely on fresh carrots:

  • Extends shelf life – Fresh carrots only last about 2 weeks in the refrigerator. Frozen carrots can be kept frozen for 8-10 months.
  • Convenient – Frozen carrots are prepped and ready to go whenever you need them for recipes or cooking.
  • Maintains nutrients – If frozen properly, carrots retain many of their important vitamins, minerals, and antioxidants.
  • Avoid waste – Freezing preserves fresh carrots and prevents having to throw them out from spoiling.
  • Budget-friendly – Buying larger quantities of fresh carrots to freeze can be cheaper than purchasing carrots weekly.
  • Year-round availability – Enjoy delicious carrots even when they are out of season by using your frozen carrots.

Freezing carrots is an easy, cost-effective way to make sure this healthy vegetable is always readily available for your family.

Picking and Preparing Carrots to Freeze

Selecting fresh, high-quality carrots is an important first step for freezing. Follow these tips for choosing and preparing carrots for the freezer:

  • Choose firm, crisp carrots without splits, mushy spots, or mold.
  • Opt for medium-sized carrots, which freeze more evenly than larger, thicker carrots.
  • Trim and peel carrots thoroughly. Cut off all greens and peel the outer layer.
  • Slice or dice carrots into your desired shape and size for freezing.
  • Blanch carrots before freezing to help retain color, texture, and nutrients. See instructions below.
  • Pat carrots dry very thoroughly before freezing.

Proper preparation is key. Make sure your carrots are fresh, cleaned, peeled, cut, blanched, and patted completely dry in order to freeze well. Removing excess moisture prevents freezer burn.

How to Blanch Carrots

Blanching is a quick pre-freeze heat treatment that helps vegetables better retain color, texture, and nutrients during freezing. Here are two methods to blanch fresh carrots:

Stovetop Blanching

  1. Bring a large pot of water to a boil. Use 1 gallon of water per 1 lb of carrots.
  2. Clean and prepare carrots. Cut or slice according to recipe or preference.
  3. Add carrots to the boiling water and blanch for 3-5 minutes, adjusting time as needed for thicker/thinner cuts.
  4. Drain carrots in a colander and immediately submerge in ice bath to stop cooking process.
  5. Let carrots cool in the ice bath for the same amount of blanching time, then drain thoroughly.

Microwave Blanching

  1. Place carrot pieces in microwave-safe bowl and add 1 tbsp of water per 1 lb of carrots.
  2. Cover bowl and microwave for 2-3 minutes until carrots are partially cooked but still firm.
  3. Drain carrots and submerge in an ice bath for 2-3 minutes to stop cooking.
  4. Drain carrots thoroughly before freezing.

Blanching takes just a few minutes but makes a big difference in preserving carrot quality when frozen. Cool carrots quickly after blanching to lock in nutrients.

Step-By-Step Instructions for Freezing Carrots

Follow this simple step-by-step guide for freezing carrots of all types:

  1. Purchase fresh carrots. Choose firm, crisp carrots without splits or blemishes. Medium-sized carrots freeze best.
  2. Trim and peel carrots. Cut off all greens attached to the carrots. Thoroughly peel the outer layer with a vegetable peeler or paring knife.
  3. Cut carrots. Slice or dice the carrots into desired size and shape. Match cut sizes if batch freezing for even cooking.
  4. Blanch carrots. Blanch sliced or diced carrots for 3-5 minutes depending on thickness. Shock in an ice bath to stop cooking process.
  5. Drain and dry carrots. Drain blanched carrots thoroughly in a colander. Spread out on towels and pat very dry.
  6. Portion carrots. For batch freezing, weigh or measure carrot pieces into recipe-ready portions. Place portions in a single layer on trays.
  7. Freeze carrots. Place uncovered trays of carrots in the freezer. Freeze until solid, about 2 hours. Transfer to bags.
  8. Pack and seal bags. Put individually frozen carrot portions into freezer bags or containers. Remove excess air, seal, label, and return to freezer.
  9. Freeze for up to 10 months. Store frozen carrots at 0°F or below. Carrots will maintain best quality for about 8-10 months in the freezer before drying out.

Follow proper blanching, cooling, draining, and packing methods as outlined above, and your frozen carrots will look and taste great when thawed.

Freeze Times for Different Carrot Cuts

The necessary freeze time can vary based on how you cut the carrots:

Carrot Cut Blanch Time Recommended Freeze Time
Matchstick carrots 2-3 minutes 8 months
Diced or cubed carrots 3-4 minutes 10 months
Carrot sticks or spears 4-5 minutes 10 months
Sliced or shredded carrots 3-4 minutes 10 months
Whole baby carrots 5 minutes 12 months

Matchstick cuts have more exposed surface area, so they won’t freeze quite as long as cubes and slices. But any cut of carrot can be frozen for 8+ months and stay delicious!

Can You Freeze Carrots Without Blanching?

Blanching is strongly recommended but you can freeze carrots without blanching if needed. Just know that the final result may be softer with some loss of flavor, nutrition, and color. Follow these tips if freezing carrots without blanching:

  • Make sure carrots are freshly harvested and in prime condition.
  • Peel and cut carrots then dry extremely well before freezing.
  • Portion carrots in a single layer on trays and freeze solid before bagging.
  • Try adding a bit of lemon juice or ascorbic acid to help preserve color.
  • Expect slightly diminished quality and shorter maximum freeze time of 6 months.

Blanching makes a big difference, but in a pinch, you can still get decent results freezing carrots without blanching first. Just don’t expect them to look or taste quite as good as properly blanched carrots.

How to Store Frozen Carrots

Storing frozen carrots properly is important for preserving quality over time. Follow these frozen carrot storage tips:

  • Use freezer-safe plastic bags, containers, or waxed paper.
  • Exclude as much air as possible and seal tightly.
  • Lay bags flat or stack containers efficiently to prevent freezer burn.
  • Label bags or containers with contents and date frozen.
  • Freeze at 0°F or below for longest shelf life.
  • Store frozen carrots away from doors or vents where temperatures fluctuate.
  • Avoid repeated thawing and refreezing.

Well-sealed freezer bags or airtight containers help protect against oxidation and freezer burn. Store bags flat and containers stacked to prevent cold air circulation around produce.

How Long Do Frozen Carrots Last?

Frozen properly, carrots can be kept frozen for 8 to 12 months before quality starts to degrade. Here are some guidelines for maximum freezer times for different carrot preparations:

  • Diced, sliced, or shredded carrots – 10-12 months
  • Carrot sticks or spears – 10-12 months
  • Whole baby carrots – 12 months
  • Matchstick cut carrots – 8-10 months

Check carrots at regular intervals and use within these time frames for best quality. Discard any carrots with freezer burn or off colors or textures.

What Happens if You Freeze Carrots Too Long?

Freezing carrots for longer than these recommended time frames can lead to the following consequences:

  • Dry, shriveled texture from excessive moisture loss
  • Freezer burn causing dry spots and off flavors
  • Oxidative browning leading to unappealing colors
  • Loss of vitamin C content
  • Mushy, mealy texture from cellular breakdown
  • Off odors and tastes from prolonged freezer times

Eat frozen carrots within 8 to 12 months for the best quality. Discard any carrots that show signs of excessive freezer damage like texture changes and dull or brown colors.


Freezing carrots at home is simple and rewarding. Follow the guidelines in this article for selecting, preparing, blanching, freezing, storing, and thawing carrots, and you will have delicious frozen carrots on hand anytime you need them. Properly frozen carrots retain nutrients, color, flavor, and texture much better than fresh carrots that go bad after a couple weeks. The next time you see carrots on sale at the market, stock up and fill your freezer so you can enjoy nutrient-rich carrots for months to come.
