Why You Should Never Put Hot Foods in The Fridge (And How to Store Them Properly)

Putting freshly cooked, steaming food in the refrigerator might seem like a great shortcut to cooling it down more quickly or to prevent it from becoming contaminated by potentially harmful pathogens left exposed to air. In reality, this idea might work on paper, but in practice, it's not recommended. The reasons? The appliance risks being damaged, as well as the food, resulting in a double negative effect in terms of preservation. However, this isn't an absolute ban, because with a few precautions, everything will run smoothly.

What Happens if You Put Hot Food in The Fridge?

The question arises spontaneously: what does it mean for the refrigerator to break down? From this point of view, manufacturers all agree that placing a very hot dish in the appliance favors an increase in the internal temperature, creating an imbalance in the refrigeration process: the machine will have to work harder to bring the degrees back to the right value and, meanwhile, the other foods already present will be exposed to unexpected heat, with the possible formation of condensation and increased humidity levels, the enemy of preservation as it favors the growth of mold. This practice, if repeated continuously, results in compromising the functioning of the refrigerator, but not only that: the foods in general alter, because in addition to those previously stored, even new arrivals undergo a thermal shock from hot to cold, which can have consequences on their organoleptic characteristics, altering flavor, taste and consistency. Waste is just around the corner.

How to Properly Store Cooked Foods in The Fridge

From leftover dinner to dishes specially prepared in excess to be consumed the next day, perhaps as a packed lunch: it's quite common to find hot foods that must be refrigerated to avoid spoilage. We've said that putting them in straight from the stove or oven isn't a good idea, but at the same time, we shouldn't underestimate the risk of leaving foods at room temperature for too long, exceeding two hours (in summer, at 86°F/30°C, one hour is enough): microorganisms tend to proliferate more easily between 39°F/4°C and 140°F/60°C, a wide range often defined as the "danger zone" due to the possibility of pathogens multiplying, leading to more or less serious poisoning. What should we do? The best way is to let the food cool for a few minutes, dividing it into several containers if you're serving a large quantity. This will lower the temperature more quickly, and once in the refrigerator, the appliance will also be able to process smaller portions more quickly than larger trays, which require more time. Place the warmed foods on the middle shelves: avoid the top shelf (which is the least cold part of the refrigerator and would slow down the cooling process) and the bottom shelf (reserved for raw foods like meat and fish that must not be subjected to sudden temperature changes).

Mistakes to Avoid and Advice

At this point, we've learned that storing very hot foods in the refrigerator is detrimental to the appliance and the food itself. However, with the right precautions, it's possible to avoid leaving food exposed to the air, which is equally bad. In summary, here are the main dos and don'ts for safe storage.

• Don't put hot pots or pans in the refrigerator. Heat increases the internal temperature of the refrigerator, causing the appliance to suffer.
• Divide larger meals into smaller portions. Storing a large amount of food in a single container slows down the cooling process. It's best to divide food into smaller portions.
• Not all containers are created equal. Once the food has cooled, transfer it to clean, airtight containers, preferably wide and shallow ones: in a deep Tupperware container, the heat is trapped instead of quickly dispersing.
• Don't overload your refrigerator. Overcrowding shelves prevents cold air from circulating evenly, creating less chilled areas where food is stored less well. Before cooking something you won't eat right away, check the situation.
• Respect the shelf life. Most ready-made meals and leftovers should be consumed within 2-3 days. If you plan to wait longer, it's best to store them in the freezer, always freezing them after they've cooled.
• Avoid reheating more than once. Finally, when you eat a dish, if it needs to be reheated, only count the portion you'll actually eat. This avoids having to reheat already-cooked food: it will taste less tasty and be more susceptible to bacterial contamination.
