Creamy roasted sweet potato and red lentil soup (vegan, gluten free)

There is nothing better than the smell of sweet potatoes roasting in the oven covered in cinnamon, garlic and lots of herbs! This roasted sweet potato and red lentil soup is so simple to make as all the veggies are roasted in the oven while the red lentils and stock simmer on the hob until soft, then everything is just blended together to make the most deliciously thick and warming bowl of soup!

The roasted sweet potatoes are so delicious I always make double when I am making this soup and keep them to have as a veggie side the following day. Another great recipe using sweet potatoes is my super easy sweet potato crust broccoli quiche which has been one of my most popular recipes. I also use sweet potatoes in my 3 ingredient pizza crust which is one of our favourites when we fancy a treat!

Tip: This soup freezes really well so feel free to make a big batch πŸ™‚
