Sweet Potato and Red Lentil Soup

👨‍🍳 Method

For the Fried onion

1. 1
   Ahead of time, rinse the legumes in a colander until the water runs clear. No need to soak.

   Colander

   💡Split peas and small lentils don't need soaking; dried beans do, otherwise they cook for hours and stay hard inside.
2. 2
   Heat the olive oil in a pot over medium heat.

   Add the onion and fry 8 minutes, stirring now and then, until the onion is soft and translucent and starts to turn golden at the edges. If it browns too fast, lower the heat.

   💡Add by cooking time: what needs long (onion, carrot, meat) goes in first, and what burns fast (garlic, dry spices) goes in last, only until fragrant.
4. 4
   Add the garlic and fry about 30 seconds to 1 minute, just until fragrant. Don't let the garlic brown.

   💡Garlic burns quickly and turns bitter. Add it only after the onion has softened, over medium heat, and add the next ingredient as soon as it smells fragrant.

4. 8
   Turn down the heat and simmer with the lid slightly open 25 minutes, until the legumes is tender and the sweet potatoes is completely soft: some of the cubes break down and thicken the sauce.

   ⚙ SimmeringStove

   💡A gentle simmer, not a boil: a hard boil dries the food out and clouds it, a slow simmer cooks it evenly.
5. 9
   Blend the soup with a stick blender until smooth.

   Stick blender

   💡Legumes cooked until they fall apart, like red lentils and split peas, blend with a stick blender into a velvety soup without cream.
6. 10
   Season with salt and the lemon juice, taste and adjust.

   💡The lemon goes in at the end: acid at the start of cooking slows down the softening of the legumes. Adjust the salt at the end, after the soup has reduced.
7. 11
   Drizzle a little of the olive oil over each bowl.
