Ingredients

• 2 tablespoons olive oil
• 1 large onion, roughly chopped
• 2 carrots, peeled and chopped
• 3 celery stalks, chopped
• 1 small leek, cleaned and sliced (white part only)
• 4 garlic cloves, smashed
• 1 cup mushrooms, sliced (preferably cremini or button)
• 1 large tomato, quartered
• 1 handful fresh parsley stems
• 2 sprigs fresh thyme
• 1 bay leaf
• 10 black peppercorns
• 8 cups water
• Optional: 1 piece of kombu (dried seaweed) for extra umami
• Salt to taste (added at the end)

Equipment

• Large stockpot (at least 6-quart capacity)
• Wooden spoon
• Fine mesh strainer or cheesecloth
• Large bowl or container for straining
• Measuring cups and spoons
• Knife and cutting board
• Storage containers or freezer bags

Instructions

1. Prepare the vegetables: Wash and roughly chop all vegetables. There’s no need to peel everything; the skins add color and nutrients.
2. Heat the olive oil: In your large stockpot, warm the olive oil over medium heat. Once shimmering, add the onion, carrot, celery, leek, and garlic. Sauté for about 5-7 minutes, stirring occasionally, until the vegetables soften and start to brown slightly.
3. Add mushrooms and tomato: Toss in the mushrooms and tomato pieces. Cook for another 3-4 minutes to develop more flavor.
4. Add herbs and spices: Add parsley stems, thyme, bay leaf, peppercorns, and kombu (if using). Stir gently to combine all aromatics.
5. Pour in water: Add the 8 cups of cold water to the pot. Increase heat to high and bring to a gentle boil.
6. Simmer the stock: Once boiling, reduce heat to low and let it simmer uncovered for 45 minutes to 1 hour. Avoid boiling vigorously as it can cloud the stock.
7. Strain the stock: Remove from heat. Using a fine mesh strainer or cheesecloth, strain the stock into a large bowl or container to remove the solids. Press down on veggies gently to extract maximum flavor.
8. Season and cool: Add salt to taste once strained. Let the stock cool to room temperature before storing.
9. Store or freeze: Pour the stock into airtight containers or freezer bags. It will keep in the fridge for up to 4 days or freeze for up to 3 months.

Tips & Variations

“Using vegetable scraps like carrot peels, onion ends, and celery leaves can make this recipe even more sustainable and flavorful!”

Tips:

• Roast the vegetables first for a deeper, caramelized flavor. Simply toss them with a little oil and roast at 400°F (200°C) for 20-25 minutes before simmering.
• Avoid using starchy vegetables like potatoes or beets, as they can cloud the stock or overpower the flavor.
• Don’t salt too much during cooking; it’s better to season your finished dish instead.
• If you don’t have fresh herbs, dried herbs work fine—just use about one-third the quantity.

Variations:

• Asian-inspired stock: Add ginger slices, star anise, and a splash of soy sauce instead of parsley and thyme.
• Italian-style stock: Incorporate rosemary, basil, and a Parmesan rind (if not strictly vegan) for extra richness.
• Spicy twist: Throw in a few dried chili flakes or a fresh jalapeño for a subtle heat.
