Frozen raw carrots (blanched, of course) stay tasty for 10 to 12 months. Unblanched? Maybe 2-3 months before they turn into sad, flavorless sponges. Don’t be that person.
Label your bag with the date, or you’ll play a guessing game next spring. And don’t thaw them in the fridge unless you want mush. Just toss frozen carrots straight into soups, stews, or roasts—they’ll cook beautifully from frozen.
