In a pan on medium heat add oil, turmeric, curry powder and stir, add in onion, garlic and ginger and stir until onion is coated in spices. Turn off heat and stir in coconut milk.
In your crockpot bowl add chicken stock and crushed tomatoes, stir. Add the coconut milk and spices from the pan and stir.
Lastly add lentils to the crockpot bowl and stir. Place lid on top.
Turn your crockpot on to low for about 5-6 hours or high for less. I know you're not supposed to lift the lid on a crockpot but you will probably need to stir it after the first 2 hours and each hour after as it sticks to the sides a little. You will need to adjust cooking times because it depends on how soft you like your lentils and how thick you want your dahl to be. I served with greek yoghurt.
This dahl is very mild if you like a larger curry flavour you may wish to double the powder.
Adjust ingredients to your liking.
My pictured dahl looks soupy it thickened up a bit with the greek yoghurt.
The dahl also thickens up in the fridge overnight. I made this batch and it's my lunch for about 3 days or I divide and freeze in portions.
Add chopped vegetables to the crock pot at the beginning for more of a meal.
I like this instead of soup on a cold day with a thick slice of bread to dunk.
