Most people know that filling your fridge and freezer to capacity can make it more efficient. However, if you don’t have enough food to fill your freezer, there are some non-food items you can use to take up space and improve its energy efficiency.

The Benefits of a Full Freezer

Every time you open your freezer, cold air escapes and warm air enters. The majority of energy used by the freezer is spent cooling the air that enters when the door is opened. When your freezer is full, there is less room for warm air to take up, and the items in the freezer help to cool down any air that sneaks in. Therefore, keeping your freezer full will result in less energy being used.

Non-Food Items to Fill Your Freezer

1. Newspaper: Stuffing the interior spaces with newspaper is an excellent way to take up space.

2. Bags of shipping peanuts: These take up lots of room in mostly empty freezers, and the bags are easily molded to fit into any space.

3. Ziplock bags filled with water: Filling these bags with water will not only improve energy efficiency, but you’ll also have ice on hand to keep your food cold if there’s a power loss.

4. Reusable plastic to-go containers filled with water: These stack up like building blocks, are easy to take in and out, and can be used for small gaps in your stocked fridge.

5. Milk jugs filled with water: This is an excellent way to reuse your milk jugs instead of recycling them.

How to Fill Your Freezer for Energy Efficiency:

1. Defrost and dry your freezer.

2. Move your food items towards the front and sides so that you can quickly access them when needed.

3. Fill the interior central cavity with the non-food item of your choice.

4. Leave some air space around the edges and top so your freezer’s thermostat can sense the temperature.

1. What are some benefits of filling my freezer?

Filling your freezer can save you both time and money. When your freezer is full, it takes less energy to keep it cold. By filling it with frozen fruits, vegetables, and meats, you can save money by buying in bulk and avoiding last-minute trips to the grocery store. Additionally, having a stocked freezer means you always have access to healthy, homemade meals, which can save you money on takeout and premade meals.

2. What are some healthy foods I can freeze?

You can freeze a variety of healthy foods, including fruits, vegetables, lean meats, and whole grains. Some examples include: berries, bananas, kale, broccoli, chicken breasts, fish, quinoa, and brown rice. By freezing these items, you can ensure you always have access to nutritious ingredients for homemade meals, even when fresh produce is out of season.

3. How can I organize my freezer efficiently?

Efficient freezer organization is key to maximizing space and ensuring you can find what you need when you need it. Use clear plastic containers or bags to store items and label them with the date and contents. Group similar items together (e.g. all fruits in one section, all meats in another) and stack them in an orderly fashion. Finally, consider investing in wire baskets or shelves to make the most of vertical space in your freezer.

4. Can I freeze leftovers?

Yes! Leftovers are a great item to freeze for quick and easy meals later on. Be sure to store them in airtight containers or bags and label them with the date and contents. Leftovers can be frozen for up to three months, but it’s best to consume them within one to two months for optimal freshness.

5. What are some tips for thawing frozen items?

The safest way to thaw frozen items is to plan ahead and thaw them in the refrigerator overnight. This method allows for slow, even thawing and minimizes the risk of bacterial growth. Alternatively, you can use the defrost setting on your microwave, but be sure to use it immediately after thawing as some areas may have begun to cook. Avoid thawing items at room temperature, as this can lead to unsafe bacterial growth.

6. How can I prevent freezer burn?

Freezer burn occurs when food is exposed to air in the freezer, causing it to become dry and discolored. To prevent freezer burn, be sure to store items in airtight containers or bags and remove as much air as possible before sealing. Additionally, try to use items within three to six months of freezing and avoid storing items near the freezer door, as this area is more prone to temperature fluctuations.

7. Can I freeze dairy products?

Yes, many dairy products can be frozen, but some (like sour cream) may separate when thawed. Hard cheeses like cheddar and mozzarella freeze well, as do butter and cream cheese. Milk can also be frozen, but may separate when thawed. To use frozen milk, thaw it in the refrigerator and shake well before using.

8. Are there any items I should not freeze?

Some items do not freeze well and should be avoided, including: lettuce, cucumbers, raw potatoes, and eggs in the shell. Cooked pasta and rice can also become mushy when frozen, so it’s best to freeze them separately and add them to dishes after thawing. Additionally, items with high water content (like watermelon) may become mealy when thawed.
