This hearty Slow-Cooker Vegetarian Lasagna is filled with lentils and vegetables so you will not miss the meat. Bursting with flavours it makes a delicious meal to enjoy between friends and family.

The preparation for this dish is quite straightforward, simply make sure you cut all the vegetables very finely otherwise they will not cook properly.

There is no pre-cooking. You can prepare the Vegetable Layer and Tomato Lentil Sauce ahead so that if you are in a rush the lasagne can be assembled in a few minutes.

If you are short in time but still want to enjoy some wholesome homemade food, then a slow cooker is your answer. You can leave food to cook gently while you are at work or busy running errands and have some delicious dishes ready by the time you return. Such an efficient way to manage your time and effort in the kitchen.

I used a 6.5 Litre Andrew James Digital Slow Cooker to make this recipe. You can read my full review here. This dish makes 6 generous portions.

    The slow cooker veg lasagne recipe calls for 500g tomato sauce. In UK that could be confused for tomato ketchup. Does recipe mean 500g passata?

      Hi – No it is tomato sauce not tomato ketchup. You can use passata but tomato sauce (homemade or store-bought) will generally have more flavour. Personally I use Seeds of Change Tomato & Basil Pasta Sauce which is available from UK supermarkets. Annabelle

    Does this recipe use dried, uncooked lentils? Or canned lentils?
