What Is The Best Alternative To Safely Cooling Foods? (The Safest Ways)

Cooking up a big batch of chili or soup? Leftovers from a large meal that needs chilling fast? Proper rapid cooling of cooked foods is critical to prevent bacterial growth.

While refrigeration is the norm, sometimes you need a quicker cooling method to avoid the danger zone between 40°F and 140°F, where bacteria multiply quickly.

In this post, we’ll explore the top alternatives to refrigeration for safely and effectively chilling down foods fast before storage. Whether you’ve cooked a large meal or prepared dishes that can’t go straight to the fridge, these methods help drop temperatures rapidly outside the danger zone.

We’ll cover various home and professional kitchen options, from simple ice bath techniques to commercial rapid chillers. Let’s review some of the best supplemental cooling and refrigeration practices for safe food handling.

What Is The Best Alternative To Safely Cooling Foods?

Ice baths or chilled water baths are the best alternative to safely cooling foods. After cooking or reheating food to proper temperatures, divide large portions into smaller shallow containers no more than 4 inches deep. Place these containers into an ice water bath to quickly chill the food.

Ensure cooling is completed within 2 hours, with the food temperature dropping from 135°F to 70°F in the first hour and down to 41°F in the next hour. This rapid chilling in an ice bath prevents bacterial growth.

Why Proper Cooling Is Critical for Food Safety?

Before diving into the various cooling methods, let’s take a moment to understand why proper cooling is critical when handling perishable foods.

When cooking foods, the high temperatures kill any dangerous bacteria that may be present. However, once foods are cooked, they enter the “danger zone” as they cool down – which is prime bacteria growth territory.

If foods spend too much time in the 40°F to 140°F danger zone, bacteria can multiply rapidly to dangerous levels that can cause foodborne illness.

Refrigerating foods quickly after cooking brings the temperature down through the danger zone quickly so bacteria cannot multiply. However, sometimes refrigeration right after cooking is not feasible. In those cases, using an effective cooling alternative before refrigerating is important.

The United States Department of Agriculture (USDA) recommends cooling foods from 140°F to 70°F within the first 2 hours and then down to 40°F or below in the next 4 hours.

This 6-hour guideline helps ensure food safety when refrigerating after cooking. Any alternative cooling method used should aim to follow these same guidelines.

Effective Alternatives For Safely Cooling Foods:

Now let’s explore some of the top methods for safely cooling foods as an alternative to immediate refrigeration:

1. Use Ice Baths

One simplest and most effective cooling alternatives is placing cooked food items into an ice bath. Fill a large container, sink, or bowl with ice and cold water. Submerge sealed food containers or resealable plastic bags of food into the ice bath. The ice chills the food quickly as it brings down the internal temperature.

Stirring the ice bath periodically will quicken the cooling process. The USDA recommends replacing the ice to maintain the cold temperature as it melts. Shoot for bringing the internal food temperature to 70°F within the first 2 hours.

An ice bath is a good method for quickly cooling down soups, stews, sauces, chili, or other liquids after cooking in large batches. It can also work for solid foods like cooked meat. Just monitor the internal food temp with a food thermometer for safety.

2. Separate Into Smaller Portions

Another tip is to divide cooked foods into smaller, shallow containers rather than leaving them in a large pot or pan. The greater surface area helps release heat faster than a larger, dense dish.

For example, transfer a large soup pot to several smaller bowls or containers before placing it in the fridge. Moving to a wide, shallow storage container can help with more rapid chilling than a tall, narrow pot.

If dividing a dish into smaller portions, allow at least 1 inch of clearance around the containers for proper cold air circulation while cooling in the refrigerator.

3. Use Rapid Chillers

For commercial kitchens that cook large batches of food, specialty rapid chilling units are designed to quickly and safely lower food temperature. These are essentially accelerated ice baths on a larger scale.

Rapid chillers use ice and cold water along with agitators or pumps to circulate the chilled water around the metal containers of hot food. This accelerated circulation can chill foods to 40°F within 90 minutes, meeting the 6-hour USDA guidelines.

While less common in home kitchens, these rapid chillers provide an efficient cooling method for restaurants, cafeterias, and caterers handling large hot foods. Proper usage and maintenance are critical for food safety.

4. Freeze in Shallow Containers

Freezing cooked foods in a thin layer is another alternative to speed up cooling if refrigeration is delayed. Transfer to shallow baking pans for casseroles, soups, sauces, and other dishes and spread to about 2 inches deep before freezing.

Once frozen solid, you can transfer the foods to a freezer bag or container for longer-term storage. The quick freeze in a wide layer reduces the time it spends in the danger zone versus cooling a large, dense dish.

To thaw, keep frozen until ready to reheat and eat, or move to the refrigerator to thaw safely over one to two days. Do not leave frozen foods at room temperature to thaw.

5. Use a Commercial Blast Chiller

For professional kitchens, another option is using a commercial blast chiller for rapid cooling. These specialized units can quickly chill cooked foods to safe temperatures in 90 minutes or less.

The food is placed in the blast chiller compartment immediately after cooking. Powerful fans circulate cold air to draw out the heat and moisture. The cold temperatures firm up the exterior while removing the internal heat. Once chilled to 40°F or below, foods can be safely moved to refrigeration.

Blast chillers provide fast, safe cooling and allow flexibility for advanced cooking. However, they require a significant equipment investment and take up substantial space.

6. Fill Containers No More Than 2-3 Inches Deep

As mentioned earlier, avoiding large dense food containers helps the cooling process. Generally, fill storage containers with cooked food no more than 2-3 inches deep before refrigerating.

Transferring to multiple smaller containers also aids in faster chilling than one giant pot or baking dish of food. Allow air space for circulation – do not overpack the refrigerator.

With smaller amounts spread out in shallow layers, the chilled air can better contact all surfaces and speed up heat transfer. Follow the guidelines of cooling food to 70°F within 2 hours and down to 40°F in 4-6 hours for optimum safety.

7. Use Commercial Sous Vide Cooling Equipment

For professional kitchens, commercial sous vide cooling equipment provides an efficient method for rapid chilling after cooking. It works by vacuum sealing foods and then lowering the temperature of the water bath to cool the food through the danger zone quickly.

Compared to traditional refrigeration, sous vide systems can chill foods 2-4 times faster thanks to the direct water contact. The vacuum sealing prevents cross-contamination as foods cool. This makes it ideal for specific ingredients, like cooked vegetables, that should maintain a crisp texture.

While the equipment represents a significant investment, it allows advanced cooking and chilling for later use. Proper usage and adherence to food safety guidelines are still required.

8. Stir Hot Liquids Frequently as They Cool

When cooling down hot soups, stews, sauces, and other liquids, stir frequently as they cool. This agitation helps release the heat quicker, so the fluid moves through the danger zone faster to refrigeration.

Avoid the temptation to cover the pot and “let it cool.” Keeping it open and stirring periodically will make a difference in the chill rate.

Once the temperature drops below 70°F or so, you can cover and move to the fridge. But don’t abandon that giant pot of boiling soup to cool unattended!

9. Chill Ingredients Before Cooking

For recipes that involve cooking raw meat, poultry, or seafood with other ingredients like vegetables, start by chilling those other ingredients first.

Keep vegetables, cheeses, sauces, and other items refrigerated until right before adding to the dish. Only combine them once the raw proteins have cooked to a safe temperature. This avoids extended time in the danger zone.

Starting with chilled ingredients helps them stay cooler as the rest of the dish cooks. Just follow proper cooking guidelines for the meats and other high-risk ingredients.

10. Allow Air Flow Around Containers

When placing hot food containers or pans into the refrigerator to cool, allow space between them for air circulation. Overcrowding can restrict airflow and slow the chilling process.

Leave at least 1-2 inches around containers and pans for proper air movement as the fridge works to lower the temperature. Keeping foods spread out helps the cool air reach all areas.

Once containers are chilled below 40°F, you can move them closer together for storage until ready to reheat and serve. Proper airflow is key during the initial rapid chilling phase.

The Importance of Monitoring Food Temperatures

Monitor internal food temperatures periodically to ensure proper chilling when using any cooling technique. Use a probe thermometer to check the progress through the danger zone on the way to 40°F or below.

The top 2 inches of dense foods will chill most quickly as they remain exposed to circulating air. However, the internal center portion will cool more gradually. Checking temps at various points ensures the inside has dropped to safe levels.

Follow the guidelines of cooling foods from 140°F to 70°F within the first 2 hours, then down below 40°F within a total of 6 hours. If progress stalls, try stirring, separating into smaller portions, or changing to an ice bath. When in doubt, throw it out rather than risk letting it linger in the danger zone.

Proper temperature monitoring ensures you meet food safety objectives. Review cooling guidelines from the USDA Food Safety and Inspection Service for additional details based on food type and preparation method.

Top Recommendations for Safe Alternative Cooling Methods

To summarize, here are 5 top recommendations to keep in mind when using alternative cooling techniques:

  • Track temperature progress – Use a probe thermometer to test foods as they cool regularly. Monitor the drop through the danger zone to ensure it meets safety guidelines.
  • Separate into smaller portions – Divide foods into smaller shallow containers rather than dense pots and pans. More surface area exposed speeds chilling.
  • Maximize airflow – Allow space between containers and pans in the refrigerator for cold air circulation.
  • Use ice baths – For soups, sauces, and other liquids, immerse sealed containers in ice baths to rapidly draw out heat.
  • When in doubt, throw it out! – If cooling stalls or goes beyond recommended timeframes, dispose of the food rather than risking bacteria growth.


Safe food handling should always be the top priority when preparing meals for yourself, family, and friends. While refrigeration is the standard for cooling cooked foods, alternatives like ice baths can help when fridge space is limited or refrigeration right after cooking isn’t feasible.

Monitoring temperatures and following food safety guidelines remains critical regardless of your chosen cooling method. When in doubt, take the conservative approach and throw foods out rather than risking contamination from slow cooling.

With some planning and diligent temperature tracking, these alternatives provide quick, effective ways to chill foods for safe storage and future use. Proper cooling ultimately helps ensure leftovers stay fresh and healthy to enjoy later on down the road.

Can you put hot food directly into the refrigerator?

Putting extremely hot food directly into the refrigerator is not recommended, as it can raise the temperature inside and potentially impact other foods. The best practice is to allow it to cool at room temperature before refrigerating.

What temperature should cooked food be before refrigerating?

The USDA recommends cooling cooked food to at least 70°F within 2 hours before refrigerating. This brings it quickly through the initial danger zone between 140°F and 70°F, where bacteria can multiply rapidly.

How long can cooked food sit out at room temperature?

Cooked food should not sit at room temperature for more than 2 hours before chilling or freezing. Within 1 hour, leftovers should be refrigerated or cooled using an ice bath or other alternative method before storing.

Can you put a whole chicken in the fridge while still warm?

A whole chicken or other large cut of poultry should be chilled down to at least 70°F within 2 hours of cooking before refrigerating. Allow the heat to dissipate briefly at room temperature, then separate into smaller portions or use an ice bath technique before storing.

Is it necessary to cool soup before refrigerating?

Yes, it is important to properly chill soups, stews, and chilis before refrigerating. The large volume of dense hot liquid can take a long time to cool in the refrigerator. Use an ice bath or rapid chilling technique to lower the temperature through the danger zone quickly.
