Updated 15 January 2026 Kitchen Genius guide for UK homes

In a busy UK kitchen, food storage can often be a challenge. With limited worktop and storage space, it’s easy to overlook proper food storage practices, leading to waste and potential health risks. This article aims to dispel common myths surrounding food storage and provide practical tips to ensure your food stays safe and fresh.

We will explore how to store various types of food, clarify misconceptions, and help you make the most of your kitchen space while reducing waste effectively.

Common Food Storage Myths

There are several myths regarding food storage that can lead to confusion and waste. Let’s take a closer look at some of the most prevalent ones.

  • Myth 1: It’s safe to store food in any container. Many people believe that any container will do for food storage. However, using non-food-safe containers can leach harmful chemicals into your food.
  • Myth 2: Refrigerating food makes it last forever. While refrigeration slows down spoilage, it does not stop it. Each type of food has a specific shelf life, even in the fridge.
  • Myth 3: You can always tell if food is bad by smell or appearance. This is not always true. Some harmful bacteria do not change the smell or look of food, making it essential to follow safe storage practices.
  • Myth 4: Freezing food destroys its nutrients. Freezing can preserve many nutrients and actually help prevent waste by extending the life of food.
  • Myth 5: It’s fine to mix raw and cooked foods. This can lead to cross-contamination and foodborne illnesses. Always store raw and cooked foods separately.

Understanding Food Storage Basics

To store food safely, it is important to understand the basics of food safety and storage.

  • Temperature Control: Keep your fridge at or below 5°C and your freezer at -18°C. This helps inhibit the growth of bacteria.
  • Use Airtight Containers: Using airtight containers prevents moisture loss and protects food from pests and spoilage.
  • Labeling: Always label your food containers with the date they were stored. This makes it easier to track freshness.
  • Know Your Food’s Shelf Life: Different foods have different storage needs. Familiarise yourself with the shelf life of common items.

Storing Fresh Produce

Fresh fruits and vegetables require careful handling to stay fresh longer. Here are some tips:

  • Keep Them Dry: Moisture can lead to spoilage. Store produce in breathable bags or containers.
  • Separate Ethylene Producers: Some fruits, like apples and bananas, produce ethylene gas, which can hasten spoilage in other fruits and vegetables. Store them separately.
  • Use the Fridge Wisely: Not all produce belongs in the fridge. For instance, tomatoes and potatoes should be stored in a cool, dark cupboard.

Storing Cooked Food

Cooked foods can be stored safely if done correctly. Here are the steps to follow:

  • Cool Down Quickly: Allow cooked food to cool at room temperature for no more than two hours before refrigerating.
  • Store in Small Portions: Divide food into smaller portions to help it cool faster and make reheating easier.
  • Use Proper Containers: Choose containers that are labelled for freezer use if you plan to freeze cooked meals.

Freezing Food: Best Practices

Freezing is a great way to extend the life of food. Here are some best practices for freezing:

  • Pre-Freeze Items: For items like berries or meats, spread them out on a tray to freeze individually before transferring them to a container. This prevents them from clumping together.
  • Leave Space: When freezing liquids, leave space at the top of the container for expansion.
  • Thaw Safely: Always thaw food in the fridge, in cold water, or in the microwave, never at room temperature.

Using Your Appliances Effectively

Maximising the use of your kitchen appliances can help with food storage and meal prep:

  • Utilise Your Air Fryer: An air fryer can be used to cook fresh produce quickly, reducing the chance of spoilage.
  • Slow Cooker for Meal Prep: A slow cooker makes it easy to prepare large quantities, which can then be stored for later use.
  • Organise Your Fridge and Freezer: Keep older items at the front and new items at the back to ensure nothing is forgotten and goes to waste.

Tips for Reducing Food Waste

Reducing food waste is not just good for your wallet, but also for the environment. Here are some practical tips:

  • Plan Your Meals: Create a weekly meal plan to avoid overbuying and ensure you use all ingredients.
  • Shop Smart: Buy in bulk for items that you use often but avoid buying items that you rarely use.
  • Repurpose Leftovers: Get creative with leftovers by turning them into new meals, such as soups or stir-fries.

Frequently asked questions

How long can I store leftovers in the fridge?

Generally, leftovers can be stored in the fridge for up to three to four days. Always check for signs of spoilage before consuming.

Is it safe to freeze food that has been cooked and then refrigerated?

Yes, if the food has been stored in the fridge for less than three to four days and has been cooled properly before freezing.

Can I store fruits and vegetables together?

It is best to store fruits and vegetables separately, as some fruits emit ethylene gas, which can cause vegetables to spoil faster.

What containers are best for food storage?

Airtight containers made of glass or BPA-free plastic are ideal for food storage, as they prevent moisture loss and protect food from pests.

How can I tell if my food has gone bad?

While smell and appearance can be indicators, it is best to follow storage guidelines and check the expiry dates. When in doubt, it is safer to discard the food.
