• Slow Cooker Lentil Soup

We love soups this time of the year, whether it's a Creamy Cauliflower and Broccoli Soup or a Spicy Carrot and Parsnip Soup, soup is always on the menu once the temperatures drop.

This easy lentil soup is properly cosy, it's rich and creamy and filling enough that it's great not just for lunch but for dinner too!

I use dried brown lentils for this soup, they cook perfectly in the slow cooker. I also add some Indian spices to make this warmly spiced. It's not too spicy so the whole family will enjoy this.

⭐️ Why You'll Love This Soup

• It's so easy to make - this really is such a simple soup to make, everything goes in the slow cooker and there's no need to precook anything!
• A great budget-friendly recipe - using dried lentils and a few store cupboard ingredients, this soup is budget-friendly and goes a long way!
• It's full of flavour! - This soup is hearty and full of flavour, it's filling too, making it great for lunch but hearty enough for dinner too.

📝 What You'll Need

The full ingredient list and detailed steps can be found in the recipe card below.

• Lentils - I use dried brown lentils for this soup. You can use green lentils if you prefer. I find that dried red lentils turn a bit mushy when cooked for a long period of time so I would avoid those. I would also avoid canned lentils, as they won't stand up to the long cooking time. You could add them in towards the end of cooking if you like.
• Vegetables - you will need one onion, cellery, carrots, a couple of potatoes, canned tomatoes and spinach for this recipe.
• Spices - I use ground cumin, turmeric, ground coriander and yellow mustard seeds for this soup. I also used fresh garlic and ginger. They are the perfect combination to give you a warmly spiced soup.
• Stock - you will need 1 litre of vegetable stock for this recipe, I used vegetable stock cubes to make the stock.

🥘 How To Make Slow Cooker Lentil Soup

1. Add all the ingredients except the spinach to your slow cooker.

2. Stir in the chopped tomatoes and stock. Cook on high for 5 hours.

3. Remove one or two ladels and blend them then return them to the slow cooker. Add the spinach and stir well. Cook for another minute or two until the spinach has wilted. Once the spinach has wilted and the potatoes are cooked through the soup is done.

🍽 What To Serve with Lentil Soup

This soup is perfect on its own but if you want to make more of a meal of it then try it with some good crusty bread, or a slice or two of White Soda Bread. It's also great with a slice of brown soda bread.

📖 Variations

• Vegetables - You can add more veggies if you like, or swap some out. You could swap the potatoes for butternut squash or sweet potatoes, you may need to reduce the cooking time though so do keep that in mind.
• Greens - We love spinach in this but kale, cavo nero, or chard would work too.
• Make it creamy - I find this soup lovely and creamy but you could take it a step futher and add some coconut milk or some double cream to get a truly luxurious soup.
