Lentil Kale Lasagne Recipe

This nutritious, creamy vegetarian lentil lasagne contains 2 types of lentils as well as a bit of ‘hidden’ kale.  It is super easy to make, hearty and filling and above all – delicious!

This vegetarian lentil lasagne contains a moderate amount of cheese so it’s low in fat yet fantastically rich and creamy thanks to the lentil filling.  It contains a handful of ingredients so preparation is very quick and uncomplicated.

What lentils to use in lentil lasagne

I used a combination of red and green puy lentils (ordinary green lentils will do too).  The red lentils add richness and thicken the sauce while the green lentils keep their shape throughout cooking adding texture.

This combination of green and red lentils creates quite a ‘meaty’ filling, and you won’t miss the real thing!

Lentils are a super convenient ingredient as they do not need pre-soaking or precooking.  Simply stir into the sauce together with the other ingredients and cook until soft (see Instructions).

How to make the filling for lentil lasagne recipe

In a large pan heat up the oil, add the bay leaf, garlic and onions and cook gently for about 3 minutes.  Add the lentils, spices, seasoning, kale, chopped tomatoes and passata as well as 2/3 of the water.

Cover and let the mixture simmer away for about 40 minutes or until the sauce has thickened and the red lentils are fully cooked.  Don’t forget to stir the mixture often to prevent it sticking to the bottom of the pan.

Stir in the parmesan cheese, add the rest of the water and make your bechamel sauce.

Once the lentil sauce is ready make the white (bechamel) sauce.  For this vegetarian lasagne I have adapted my 3-ingredient simple white sauce recipe.  It takes minutes to prepare.

In a saucepan melt the butter, add the corn flour and whisk together until smooth.  Pour in the milk, increase the heat and whisk until the sauce thickens and starts bubbling up.  Remove from the oven, season lightly and spoon over the lasagne (see below).

This sauce will thicken as it stands.  If that happens simply add a drop of milk.

You can now put the lasagne together.

Lightly grease the bottom of your lasagne dish (20 cm x 30 cm) and cover with 3 lasagne sheets.  Add half of the sauce, smooth out and cover with 3 more lasagne sheets.  Create another layer of sauce and lasagne sheets, sprinkle the cheddar cheese over the top, pour over the white sauce and bake in a preheated oven for one hour. Half way through cover loosely with paper to prevent the lasagne browning too much.

See Instructions below for more detail.

What other spices can I use in healthy vegetarian lasagne

I only used oregano and paprika but you can also use basil or thyme if you like.  Use a combination of these spices or just one of them.  Entirely up to you.
