In a heavy bottomed pan (I used the pressure cooker pan) add in the grated beetroot fry well for about 5 mins or till the raw smell leaves. Now add in the milk.
Cook well until the milk is completely gone .By this time the beetroot should also have been almost cooked .at this stage add in the sugar.
The sugar will starts to melt down and halwa will again become watery. Add this stage add in the cardamom powder and Ghee. Keep the stove in a medium flame and cook till the halwa starts leaving the edge of the pan. Garnish with nuts and serve.
Notes
You can prepare carrot halwa by following the same recipe just by replacing beetroot with carrot
You can also skip adding nuts if you don’t prefer.
