"Easy spicy potatoes using unique spices all thrown into a slow cooker! No pre-cooking anything! This recipe is a modified version of an old Sri Lankan spicy potatoes recipe, but is for all tastes! This recipe goes well with curried chicken and rice."
Pour olive oil into the bottom of a slow cooker. Layer onion slices over the oil. Add green chile peppers, mustard seeds, cumin seeds, sugar, garlic, salt, and pepper. Layer potatoes on top, seasoning each layer with a sprinkle of salt and red pepper flakes.
Cook on High until potatoes are tender, 3 1/2 to 4 hours. Stir gently before serving.
