This humble soup has always come through for me. It’s nourishing, forgiving, and helps use up any veggie zombies haunting your fridge.
This is my go-to soup when I want something healthy and filling, especially when I have a lot of vegetables wilting away in my fridge.
What I love most about this recipe is its flexibility. As long as you have some type of lentil or bean and a variety of vegetables, it works wonderfully. Don’t hesitate to use whatever you have on hand and take this chance to clean out your fridge. For example, I added tomatoes, mini potatoes, and peppers—three ingredients I had never used before—and it turned out great. No matter what you include, it may look like sludge, but it will taste fantastic!



Sludge Soup:
Ingredients:
- 1 Onion (diced)
- 4-8 Garlic cloves (minced or diced)
- 1 Bunch of celery (chopped)
- 4-6 Carrots (peeled and chopped)
- 1 Bulb of fennel with stems and fronds (chopped)
- 1 Bag spinach or kale (frozen or fresh-chopped)
- Any other veggies you want to use up (I used tomatoes, mini potatoes, and peppers in mine)
- 2 Cartons of stock
- 1 Bag of dried lentils
- 1 Bag of dried beans (any variety – I used blackeye peas in this version)
- 2 Tbsp Olive Oil
- Garlic salt
- Crushed red pepper (optional)
- 4-8 cups filtered water (as needed)

This recipe is mostly all about chopping, prepping, and giving yourself plenty of time to let it all cook down. Since this soup is so healthy, you can go a bit wild with the finishing touches. I like to pair mine with some sourdough toast and top the soup with some Greek yogurt, chili crisp, or a fried egg.
Pro tip: watch this video on properly rinsing and draining your lentils or beans.
Recipe:

Add stock.
-
Rinse lentils and beans, then add them to the pot.
-
Add the rest of the veggies.

Once the beans are soft it is ready to eat.
