  • 1 head cauliflower


  • Wash cauliflower under tap water.
  • Pick off leaves, and cut into bite size pieces; consider what you might use the cauliflower for, egg muffins or egg casserole require small pieces, soups, stir fries or sautees do not. Stems are perfectly fine to use as well as the florets.
  • Bring a large pot of water to boil. Working in batches, blanch the cauliflower: simmer for 1 ½ minutes, then remove from the pot using a slotted spoon and transfer immediately to a bowl of ice water to stop the cooking process.
  • Repeat with remaining cauliflower.
  • Drain well.
  • Arrange on a large baking sheet. I love these baker's half sheets.
  • Freeze for 4 hours- overnight.
  • Transfer to a freezer bag, labelled with the contents & date. Pictured in this post are these reusable silicone freezer bags.
  • Freeze for up to 1 year!
