Step-by-Step Instructions

Step 1: Prepare Your Vegetable Scraps

Rinse all vegetable scraps thoroughly to remove any dirt. Chop larger pieces into roughly 1-inch chunks for even cooking. Remember, these are parts you’d normally throw away—carrot tops, onion skins, and celery ends are packed with flavor!

Step 2: Sauté the Base

Heat olive oil in a large pot over medium heat. Add any aromatic scraps (onion ends, garlic pieces) and sauté for 2-3 minutes until fragrant. This builds a flavor foundation for your sustainable soup.

Step 3: Add Remaining Ingredients

Add all remaining vegetable scraps, the parmesan rind, bay leaf, and water. Bring to a gentle boil, then reduce heat and simmer for 30-40 minutes, allowing the flavors to meld beautifully.

Step 4: Strain and Serve

Strain the soup through a fine-mesh sieve, reserving the nutritious broth. You can either discard the now-spent vegetable scraps in your compost bin or blend a portion back into the soup for added texture.
