Slow Cooker Black Lentil Dahl

Get a sneak peek of my brand new cookbook, Six Ingredient Slow Cooker, with this comforting black lentil Dahl recipe.

Can I use tinned lentils instead of dried ones?

For this recipe, dried black lentils (urad dal) are ideal as they absorb flavour during the slow cook. Tinned lentils may become too soft and won’t achieve the same creamy texture.

Do I need to soak black lentils before cooking?

Soaking is optional, but soaking the lentils for a few hours or overnight can help reduce cooking time and improve digestibility. If you’re short on time, you can cook them from dry—just allow the full cooking time.

How long should I cook black lentil dahl in the slow cooker?

Cook on low for 6–7 hours or high for 3–4 hours, until the lentils are tender and the dahl is thick and creamy.

Can I freeze this black lentil dahl?

Yes, it freezes very well. Let it cool completely, then transfer to an airtight container. Freeze for up to 3 months. Defrost overnight in the fridge and reheat until piping hot.

Is this dahl suitable for vegans?

Yes – the base recipe is naturally vegan. Just double-check any toppings (like yoghurt or ghee) and use plant-based alternatives if needed.

What should I serve with black lentil dahl?

It’s delicious with steamed basmati rice, naan, or chapatis. Add a side of cucumber raita, pickled onions, or mango chutney for extra flavour.

Can I make this recipe spicier or milder?

Absolutely. Adjust the level of chilli or garam masala to suit your taste. You can also stir in coconut milk or yoghurt at the end to mellow the heat.

Is this recipe good for meal prep?

Yes – it’s perfect for batch cooking and keeps well in the fridge for 3–4 days. The flavours actually improve over time, making it ideal for midweek meals.

Can I add vegetables to this slow cooker dahl?

Definitely. You can stir in spinach, peas, or chopped tomatoes towards the end of cooking to boost the nutrition and variety.

What makes black lentil dahl different from other dahls?

Black lentils create a thicker, richer texture and hold up well during long cooking, giving this dish a hearty and comforting quality that’s ideal for slow cooking.
