by

That papery skin you peel off an onion isn’t trash—it’s a free, versatile resource waiting to be used. Packed with flavor, color, and nutrients, onion skins can be repurposed in countless ways to reduce waste and benefit your home, garden, and health.

Before you throw them away, discover these 11 creative and practical ideas to transform this kitchen scrap into a valuable asset.

1. Brew a Rich, Golden Broth
Turn scrap into stock! Onion skins are the secret to a deeply flavorful, beautifully colored vegetable broth. Save the skins from 3-4 onions and add them to a pot of water with other vegetable scraps (like carrot peels and celery ends). Simmer for an hour, then strain. You’ll be left with a rich, golden broth perfect for soups, stews, and sauces.

2. Craft a Natural Dye
Unleash your creativity with a natural dye. Onion skins produce stunning shades of amber, gold, and rusty orange. Boil a large handful of skins (from about 10 onions) in water for 30-45 minutes. Strain the liquid and use it to dye Easter eggs, fabric, yarn, or even paper for a beautiful, earthy touch.

3. Supercharge Your Compost
Give your compost pile a nutrient boost. Onion skins break down quickly, adding valuable organic matter and minerals to the mix. Simply toss them into your compost bin with your other kitchen scraps to create richer, healthier soil for your garden.

4. Mulch Your Garden Beds
Use dried onion skins as a lightweight, nutrient-rich mulch. Spread a thin layer around the base of your plants to help retain soil moisture, suppress weeds, and slowly release nutrients as they decompose. The subtle scent may even help deter certain pests.

5. Concoct a Powerful All-Purpose Cleaner
