Onion Peels: The Secret Ingredient Grandma Never Wasted

Onion peels (yellow, red, or white)

A clean tray or baking sheet

Instructions:

Collect the dry outer peels of onions and rinse lightly if dusty. Pat dry.

Spread them out on a tray and let them dry in the sun for several days, or place them in an oven at low heat until crisp.

Once fully dry, grind the peels into a fine powder using a spice grinder or mortar and pestle.

Store in a small glass jar with a tight lid. It can last for months when kept dry.

Just a pinch can season roasted potatoes, stews, or grilled meats with a gentle, earthy flavor.

Extra Tips from the Kitchen

Add whole onion peels directly into soup stock for a deeper golden color, then strain before serving.

Mix a little peel powder with salt and garlic for a homemade seasoning blend.

Red onion peels give a beautiful natural hue to rice or pasta dishes.

Combine with herbs like thyme or rosemary for fragrant roasted vegetables.

Using onion peels is a small, inexpensive way to boost flavor, color, and aroma in everyday cooking while honoring a timeless kitchen tradition. Grandma knew best—nothing goes to waste in a loving, resourceful kitchen.
