Freezing potato mash made with root and fresh vegetables

I regularly make homemade mash using the following ingredients

• Potatoes


• Sweet Potatoes


• Carrots


• Cabbage (2 varieties)


• Onion


• Leek


• Butter


• Cream


• Cayenne Pepper / Paprika

This is the first time I have made a 4-5 litre batch and would like to freeze it. Will it be safe to eat despite having fresh cabbage mashed into the recipe?
