Do you have to par cook vegetables before freezing?

No, it is not necessary to par cook vegetables before freezing. Blanching is a process that involves briefly heating the vegetable in boiling water before submerging it in ice water to stop the cooking process. This process helps preserve the vegetable's color, flavor, and nutrients, and also helps to minimize freezer burn. While par cooking involves partially cooking the vegetable before freezing, blanching is a quicker and more effective method for preserving the vegetable's quality during the freezing process.
