Important Recipe Notes
- Don’t add pasta too early. Always add it in the last 30 minutes so it doesn’t turn mushy and fall apart in the soup.
- Cut vegetables evenly. Try to dice the carrots, celery, and courgette in similar sizes so they cook at the same rate and stay nice and tender.
- Make sure to sauté the onion, carrots, and celery first. It builds a deeper, richer soup flavor.
- Rinse the beans well. This helps remove extra salt and starchy liquid, making the soup cleaner and lighter.
- If the soup gets too thick after cooking, just add a little extra hot water or stock before serving.
- Slow cookers can mellow seasoning, so always do a final taste test and adjust salt, pepper, or lemon juice before serving.
- Add the spinach and kale at the end so they stay bright and don’t overcook.
- Great for leftovers. The soup thickens overnight, so just add a splash of water or stock when reheating to bring it back to the right consistency.
