Chef’s Notes
Red lentils cook quickly and naturally thicken the soup.
Fresh spinach is added near the end to preserve its vibrant colour and nutrients.
Lemon juice brightens the flavours and balances the richness.
This soup thickens as it cools; add extra broth when reheating if needed.
Tips for Success
Rinse lentils thoroughly before cooking.
Use low-sodium broth so you can better control the salt level.
Stir occasionally to prevent lentils from sticking to the bottom of the pot.
Add spinach only at the end to avoid overcooking.
Blend only part of the soup if you enjoy a mix of creamy and chunky textures.
Fresh herbs added before serving enhance flavour and presentation.
A drizzle of olive oil or a spoonful of yoghurt makes a delicious garnish.
