How to Freeze Carrots

A quick-and-healthy meal is always within reach if you have frozen carrots. Find all the tips and tricks for perfectly blanched (or unblanched) frozen carrots, kept whole, diced or sliced. The freezer is your friend!

Frozen carrots are a lifesaver for quick soups and stews. Once you learn how easy it is to freeze carrots, you won’t leave the market (or grocery store) without an extra bushel of carrots!

Small frozen carrots are great for roasting. Add a good drizzle of olive oil, salt and pepper and pop them into a hot oven. Or briefly steam or sauté to finish cooking frozen baby carrots.

You can also use diced, frozen carrots straight from frozen for a quick-and-easy weeknight carrot soup.

How to freeze carrots

Freezing blanched carrots is the best way to preserve fresh carrots (or any other root vegetable) for a quick start on your mirepoix (or soffrito).

Blanching preserves the nutritional value and the colour. And flash freezing ensures individually frozen carrots instead of a big chunk of diced carrot.

Step 1. Prep the carrots for freezing

Scrub your carrots clean with a vegetable brush and remove the outer layer of the carrot with a vegetable peeler.

I freeze the off-cut pieces of carrot in a separate bag to use for stock, along with all kinds of discarded veggies that still have flavour and nutritional value.

Use a sharp knife and cut the carrot tops from the peeled carrots, including that bit at the top that traps so much dirt. Then grab a cutting board and cut the carrots depending on how you plan to use them.

  • Whole roasting or sauteing: I like to keep small or baby carrots intact for a quick sauté. Or medium-sized carrots for oven roasting. Try this harissa roasted carrot side dish for whole frozen carrots.
  • Stir fries: Cut carrots into lengthwise strips and then matchsticks (aka julienned carrots) or batons. You can also slice carrots into rounds.
  • Carrot cake: Grate the carrot as you would when making carrot cake with shredded carrots.
  • Stews, soups and casseroles: I prefer small to medium-sized dice for my mirepoix (the classic mix of celery, onion and carrots).

Or quickly chop carrots into rough, small chunks with a food processor. It is a great way to process many carrots in no time!

Step 2. Blanch carrots

Bring a large pot of water to a rolling boil over high heat, with enough water to comfortably cover the carrots.

While you wait for the water to reach a rolling boil, get your ice bath ready. Fill a large bowl (large enough to fit all your carrots) with cold water and ice. Don’t skip the ice bath!

Add the sliced carrots to the pot of rapidly boiling water and cook for two minutes.

I don’t change the blanching time depending on the size of the carrot pieces. I give all of my frozen vegetables a two-minute cook. This way, I know to subtract two minutes from the cooking time when relevant.

Step 3. Ice bath

This essential step creates crisp, vibrant carrots.

Drain the grated, diced, sliced or small whole carrots in a colander, or use a slotted spoon to remove whole carrots. And immediately drop them into the bowl of ice-cold water.

Let them cool completely, about three to five minutes.

Transfer the cold, par-cooked carrots to a clean kitchen towel and gently pat dry. Or use paper towels.

Step 4. Flash-freeze carrots in a single layer

Line a baking sheet (cookie sheet or rimmed baking tray) with parchment paper and arrange the blanched carrot pieces in a single layer.

Transfer the lined baking sheet to the freezer until the carrots are frozen solid – about two hours.

I store the parchment paper to reuse for the next batch of frozen vegetables.

Step 5. Store frozen carrots in airtight containers

Now you can transfer your carrots to an airtight container or freezer bag.

Resealable plastic freezer bags (like a Ziploc bag) work best because you can squeeze out as much air as possible to prevent freezer burn. And it’s easy to label the freezer bag with the date using a permanent marker.

You can use a vacuum sealer if you have one. Alternatively, place the bag in a water bath to squeeze out air – taking care to not let any water get into the bag of carrots.

I wash and reuse my freezer bags for the next batch of frozen vegetables.

Reusable silicone bags also work well for diced carrots. They’re a bit pricey, but it’s a great way to still get the excess air out without a single-use plastic product.

Properly frozen carrots can keep for up to a year in the freezer. But I prefer to use it within six months before any freezer burn sets in.

Why blanch carrots before freezing?

While it may seem like a hassle, it is a good idea to blanch carrots (or other similar root vegetables) before freezing.

  1. Blanching washes off any microorganisms that might remain on the surface.
  2. It partially cooks the carrots, making the cooking time from frozen faster.
  3. It slows down the enzyme action that causes loss in flavour, colour, texture and nutrients allowing the frozen carrots to last longer in the freezer.

Properly blanched, flash-frozen individual carrots (or diced carrots) are great for long-term storage.

The frozen carrots can last up to a year in the freezer. But I try to finish mine within six to eight months before freezer burn can set in.

While we know that blanching extends the freezer life of these vegetables, exactly which parts of vegetable blanching lore are worth the effort? According to a Serious Eats article on the rules of big-pot blanching, the most important is an icy cold bath after the brief boil.

Can I freeze carrots without blanching?

Yes, you can skip the blanching process. However, you will need to use the frozen carrots within a month because blanching inhibits the enzymes responsible for colour and nutrient loss.

Tips for freezing carrots without blanching:

  • Always peel the carrots if you don’t plan to blanch them. It removes more microorganisms from the outer layer of the carrots. They contribute to the loss of colour and nutrients.
  • If you skip blanching and flash freezing, it is best to dice the carrot finely and use it for mirepoix (that mix of diced carrots, celery and onion that gets a soup or stew going).
  • Don’t defrost the carrots to use raw in cold salads. It is best to use them for cooked dishes like soups, stews and mirepoix.
  • Use it within one month.

How to use frozen carrots

Frozen carrots are best used in hot dishes, especially soups, stews and mashed carrots that can do with the extra moisture.

There is no need to thaw frozen carrots. You can use them straight from frozen.

Don’t use frozen carrots for raw dishes like raw carrot salads. Fresh, raw carrots will always work best here.

Frozen carrots can get soggy and lose their texture once defrosted.

Frequently asked questions

What is the best way to freeze fresh carrots?

The best way to freeze fresh carrots is to blanch them first. Blanching stops the enzymatic action and preserves the crisp texture. Simply trim and peel the carrots, then cut them into the desired size. Blanch in boiling water for two minutes, cool them in an ice bath, drain them, and let them completely dry before freezing.

Can you freeze raw carrots without blanching?

Yes, you can freeze raw carrots without blanching. However, they tend to lose their crunchy texture and vibrant colour when frozen raw. To freeze raw carrots, cut them into small pieces, freeze on a flat surface until solid, then transfer them to a freezer-safe resealable bag and expel excess air. Use within a month.

Is it better to freeze carrots raw or cooked?

It is better to freeze cooked carrots. Blanching carrots before freezing helps to preserve their texture and flavour. Cooked carrots will also last longer in the freezer.

Do carrots get soft after freezing?

Yes, carrots can become soft after freezing. Blanching them before freezing helps to preserve their texture and flavour and will prevent them from becoming mushy.

What is blanching?

Blanching refers to partially cooking vegetables in boiling water (this cooking process can also be called parboiling). After boiling, plunge the vegetables into ice-cold water to stop cooking.
