Most people throw away tuna cans after consuming their meal, but these small, sturdy containers can actually become amazing tools for setting up and storing food in your refrigerator. With a little cleaning and creativity, tuna cans can help you save space, reduce waste, and keep your fridge tidy.
1. Clean the Cans Thoroughly Before Use
Before reusing tuna cans, it’s crucial to make sure they’re clean and safe for food storage.
Wash each can with hot, soapy water to get rid of oil and residue.
To get rid of any lingering fish smell, soak the cans in a solution of baking soda and vinegar for 15–20 minutes.
Dry them completely to prevent rusting.
You can also line the inside with parchment paper or plastic wrap if you plan to place food directly inside.
2. Store Small Leftovers and Ingredients
Tuna cans are perfect for holding small portions or leftover ingredients that often clutter your fridge such as chopped onions, minced garlic, sliced fruits, or salad toppings.
Just portion your food into the cans, then cover them with cling wrap or reusable silicone lids. This keeps the ingredients fresh while taking up minimal space.
3. Organize Meal Prep Items
If you love prepping your meals in advance, tuna cans are perfect for organizing ingredients. You can store portions of cheese, sauces, herbs, or nuts separately. When it’s time to cook, simply grab the can you need – quick and convenient.
For extra order, place several filled cans on a small tray or shelf section in your fridge. This method helps you see everything at a glance and decrease waste from forgotten ingredients.
4. Use as Mini Containers for Freezing
Clean tuna cans also work well for freezing small food portions. You can freeze soup stock, sauce cubes, lemon juice, or baby food in them.
Tip: Don’t fill the cans to the top – leave a bit of space because liquids expand when frozen. Once frozen, you can transfer the contents into bags or containers for long-term storage.
5. Label for Easy Identification
Since all tuna cans look the same once cleaned, labeling is key. Use masking tape or stickers to write the food name and date.
This helps you check how long something has been in the fridge and makes sure you use older items first – preventing waste and spoilage.
6. Important Safety Notes
While tuna cans are practical, avoid using them for acidic foods like tomato sauce or citrus, as the metal can react and affect flavor.
Also, don’t reuse cans with sharp edges or rust spots. For longer storage, transfer the contents into glass jars or airtight containers after chilling.
Conclusion
Reusing tuna cans is a simple and sustainable way to make the most of what you already have. With proper cleaning and smart organization, these small containers can become perfect tools for food storage in your refrigerator.
