    This slow cooker or stovetop Lentil Stew will warm you up on cold evenings. It's easy, hearty and bursting with vegetables and great taste. Optional harissa paste gives a lovely depth of warm flavor. Vegan and gluten-free.

    Slow Cooker Lentil Stew

    (NOTE: Stovetop method also given below)

    I love a good warming stew. When the weather draws in and the nights get shorter, I crave it.

    I want big bowls of hot vegetables, thick with their own sauce.

    And I want gently spiced one-pot dishes. I want to be warmed from the inside out.

    That's where this slow cooker lentil stew comes in. You could substitute many vegetables so it's a great way to reduce food waste and use up your vegetable box.

    The cumin and harissa paste enliven the vegetables and pack this simple vegan slow cooker casserole to full of aromatic flavours.

    It's nourishing, filling and fragrant.

    Perfect on its own or mopped up with fresh bread. Try my easy flatbread or kale herb soda bread.

    Slow Cooker Stews

    Using a slow cooker (crock pot) means you can add the ingredients in the morning, and return from work to the air in the house dancing with spice.

    It's such a flexible and stress-free way to prepare a meal!

    Plus, I love how a slow cooker makes like so easy. You can ignore it all day while it makes everything extra delicious.

    I love it for stew, but also my slow cooker chocolate beetroot cake (not vegan).

    Ingredients for easy vegan slow cooker lentil stew with harissa paste. Gluten free and full of vegetables.

    Ingredients in Lentil Stew

    Onion
    Garlic
    Celery
    Carrot
    Ground cumin
    Tomato Paste/Puree
    Vegetable Stock/Broth
    Chopped tomatoes
    Green lentils (feel free to use red lentils instead)
    Cabbage or Kale
    Spinach
    Lemon
    Harissa paste (spicy North African paste usually found in the ethnic aisle of most major supermarkets. Rose harissa works well too and is less firey)

    Most of the ingredients are store cupboard staples, but this recipe is very flexible, so feel free to make substitutions.

    That's one of the great things about slow cooker casseroles, they're endlessly adaptable.

    If you use the cumin and harissa paste, it will still taste similar if you substitute parsnips, kale and red lentils.

    Vegan Slow Cooker Lentil Stew with Harissa is easy to make and full of flavour.

    What is harissa?

    Harissa is a hot and spicy condiment paste traditional to North Africa and the Middle East, particularly found in Tunisia and Morocco.

    It's normally a blend of red peppers, dried red chillies, garlic, cumin and caraway, plus a mixture of other spices that might include rose petals.

    Different brands will all have different mixes, so some may be hotter than others, or perhaps sweeter, spicier or have rose notes in it.

    How do you use Harissa?

    Harissa is spicy, aromatic and adds a complex depth of flavour to many dishes. There are many ways to use it:

    • Add flavour to soups and stews
    • A marinade or rub for meat or vegetables
    • Add extra punch to tomato-based sauces
    • Mix with oil on roasted vegetables or potatoes
    • Swirled into cooked couscous

    Harissa is quite spicy, so start with just a little and add more if you like it hot. Rather than just heat for heat's sake, harissa brings many other flavours along with it making it not just hot, but truly, fragrantly, warming.

    What is a substitute for harissa paste?

    Harissa is available in the ethnic section of major supermarkets, but if you can't find it you could try to make your own or substitute it with chilli paste or your favourite hot sauce.

    If you still want that typical harissa flavour, you could add a pinch of ground cumin and caraway to the chilli paste.

    If you're looking for other vegan Crock pot recipes try my red lentil dahl, kale and ale stew or Spanish beans in tomatoes.

    They're all easy to make on the stove top, but add the ingredients to a slow cooker and they'll be extra easy.

    Recipes From A Pantry's caponata recipe (aubergine/eggplant stew) would also be great in a slow cooker. I made it for dinner last night and it's delicious!

    It's a really easy recipe that's bursting with flavor. Just follow these simple steps:

    How to make vegan lentil stew in the slow cooker

    2: add the tomatoes, stock, lentils, tomato puree and harissa paste (if using). If you're using cabbage (instead of kale) then you can add it now. Give it a stir, set the slow cooker and leave it to allow it to turn into lentil stew casserole goodness. It's that easy!

    Step 4. If you're using kale or spinach, add just before serving and stir it in to soften.

    Tips and Tricks for Lentil Stew

    • Try adding diced peeled potatoes to make it even heartier.
    • If you like spice, but don't have harissa, then add in a teaspoon or two of dried chilli flakes.
    • You can make lots of swaps for this Lentil Stew.
    • Try adding whatever root vegetables you have. For softer vegetables (like zucchini or eggplant) add them close to the end of the cooking time.

      I love that you gave the size of the slow cooker - I come across so many recipes that don't state how big a crockpot was used, and then you're left guessing whether you need to double up the ingredients etc.

      I made this yesterday. It's really easy and so flavourful. I've had a jar of harissa for ages but didn't know what to do with it so found this recipe. I'll make a batch again soon for the freezer and meal planning.
