If you’ve ever wrapped half an onion in cling film or tossed it into a plastic bag, only to find your fridge smelling like a deli, you’re not alone. Enter the onion keeper—a small but mighty kitchen essential that helps you store leftover onions cleanly, safely, and odor-free.
Let’s break down the uses and benefits of an onion keeper, and why this unassuming container deserves a spot in your fridge.
What Is an Onion Keeper?
An onion keeper is a reusable storage container specifically designed to hold half-used or pre-cut onions. Typically made of plastic or silicone, it features:
- A tight-fitting lid to contain odors
- A shape that cradles halved onions securely
- Dishwasher-safe, BPA-free materials
- Sometimes a fun design that mimics the look of an onion!
Benefits of Using an Onion Keeper
1. Keeps Your Fridge Smelling Fresh
Cut onions are notoriously pungent. A sealed onion keeper traps that strong aroma, so it doesn’t transfer to other foods or leave your fridge smelling like onions for days.
2. Prevents Cross-Contamination
Storing onions openly or loosely wrapped can lead to contamination, especially if they come into contact with raw foods or open produce. An onion keeper provides a safe, hygienic barrier.
3. Extends Onion Freshness
Exposed onion surfaces dry out quickly. By keeping them in an airtight container, you preserve moisture and texture, so they stay fresher for longer.
4. Eco-Friendly Alternative
Forget single-use wraps or bags—onion keepers are reusable, helping you reduce plastic waste while keeping things tidy in your kitchen.
5. Multipurpose Use
While it’s perfect for onions, you can also use the container to store:
- Garlic bulbs or shallots
- Half lemons or limes
- Small fruits or veggie chunks
- Cheese wedges or snacks
When to Use an Onion Keeper
- After slicing half an onion for a salad or sandwich
- When meal prepping chopped onions ahead of time
- To store pre-sliced onions for burgers, tacos, or stir-fries
- Anytime you want to prevent onion smell from taking over your fridge
