Melt the butter with the olive oil in a big pot. Toss in the celery and let it sauté for a bit until it softens slightly.
02 -
Stir the garlic and red lentils into the pan. Let everything cook for a minute or so while mixing, helping the lentils soak up the butter mixture.
03 -
Pour the broth in and wait for it to start bubbling gently. Add any cheese rinds you’re using now. Lower the heat and pop the lid on, letting it cook for around 20 minutes until the lentils are completely tender.
04 -
Mix in the broccoli or any other veggies you want to use. Cook for 5-10 more minutes, just until they soften.
05 -
Take the pot off the heat and use a hand blender to purée everything until creamy. If using a jug blender, leave space for steam to escape by lifting the small cap, and cover with a towel for safety.
06 -
If it feels too thick, stir in a splash of hot broth to thin it out. Sprinkle in the grated cheese and stir until it melts perfectly into the soup.

Have a taste and add salt or pepper if it needs more. Ladle into bowls and enjoy warm, maybe with a chunk of bread.
