How to Make Homemade Vegetable Broth from Kitchen Scraps
Published Date:
Cooking healthy meals often leaves behind a mountain of vegetable trimmings: onion skins, carrot tops, celery ends, and garlic papery skins. Instead of throwing them into the trash, you can collect and transform them into a rich, aromatic, and deeply flavorful homemade vegetable broth.
This zero-waste kitchen habit not only saves money but also provides you with a chemical-free base for soups, stews, and grains.
1. What Scraps to Save
Keep a container or bag in your freezer to collect clean trimmings as you cook.
- Great additions: Onions, garlic, carrots, celery, leeks, scallions, mushrooms, and herbs (parsley, thyme).
- Avoid: Brassicas (cabbage, broccoli, kale, Brussels sprouts) which turn bitter, starch-heavy potatoes which cloud the broth, and beets which turn it bright red.
2. The Simmering Process
Once your bag is full, it’s time to brew.
- Step: Empty the scraps into a large pot, cover with water, add a bay leaf and a few black peppercorns. Bring to a boil, then reduce heat and simmer gently for about 45 to 60 minutes. Strain out the solids, and press them to extract every drop of liquid.
3. Storing Your Liquid Gold
Let the broth cool, then pour it into jars or freezer bags.
- Duration: Keep in the refrigerator for up to 5 days, or freeze for up to 3 months. Freezing in ice cube trays is perfect for quick flavor additions to sauces later.
