Canning chili at home is a rewarding way to enjoy a delicious, hearty meal anytime you crave it. However, safety is paramount when preserving food, and understanding the correct processing times is crucial to prevent botulism. This guide will provide a comprehensive overview of processing times for canned chili, along with essential information about ingredients, preparation, and safe canning practices.
Understanding the Importance of Processing Time for Canned Chili
Processing time refers to the amount of time a jar of food needs to be heated at a specific temperature during the canning process. This heat destroys harmful microorganisms, including Clostridium botulinum, the bacteria that causes botulism. Botulism is a severe and potentially fatal illness, so adhering to recommended processing times is non-negotiable.
Chili is considered a low-acid food, meaning it has a pH level higher than 4.6. Low-acid foods require pressure canning to reach the necessary temperatures (240°F/116°C) to kill botulism spores. Water bath canning, which is suitable for high-acid foods like jams and pickles, is not safe for chili.
The processing time depends on several factors, including jar size, altitude, and the specific recipe used. Always consult a tested recipe from a reliable source, such as the National Center for Home Food Preservation (NCHFP) or your local extension office, to ensure the safety of your canned chili.
Essential Ingredients and Preparation for Safe Canning
The ingredients you use and how you prepare them significantly impact the safety and quality of your canned chili. Using fresh, high-quality ingredients is the first step.
Choosing the Right Ingredients
Tomatoes: Use only high-quality, disease-free tomatoes. Core and peel them before adding them to your chili.
Beans: Dried beans must be properly rehydrated and cooked before canning. You can either soak them overnight or use the quick-soak method.
Meat: If using meat, such as ground beef or venison, brown it thoroughly before adding it to the chili mixture. Drain off any excess fat.
Vegetables: Onions, peppers, and other vegetables should be washed and chopped.
Spices: Use fresh, high-quality spices for the best flavor.
Prepping Your Chili
Follow a tested recipe precisely. Do not alter the ingredient ratios or add ingredients not specified in the recipe.
Sautéing vegetables can enhance the flavor of your chili. Cook onions, peppers, and other vegetables until they are softened.
Brown the meat thoroughly, ensuring it’s cooked through before adding it to the chili.
Combine all the ingredients according to the recipe instructions.
Simmer the chili to allow the flavors to meld and to reduce the liquid slightly. This helps prevent siphoning during the canning process.
Pressure Canning: The Safe Method for Chili
Pressure canning is the only safe method for preserving low-acid foods like chili. A pressure canner creates a high-pressure environment that allows the internal temperature of the jars to reach 240°F (116°C), which is necessary to kill botulism spores.
Preparing Your Pressure Canner
Before each use, inspect your pressure canner to ensure it’s in good working condition. Check the gasket, vent pipe, and pressure gauge.
Add the required amount of water to the canner according to the manufacturer’s instructions. Typically, this is about 2-3 inches of water.
Place the canning rack in the bottom of the canner. This prevents the jars from sitting directly on the bottom, which could cause them to break.
Filling the Jars
Use clean, sterilized canning jars. Sterilize jars by boiling them for 10 minutes.
Heat the jars before filling them with hot chili. This prevents them from cracking when exposed to the hot chili.
Ladle the hot chili into the hot jars, leaving the recommended headspace. Headspace is the space between the top of the chili and the lid of the jar. A general recommendation for chili is 1 inch headspace.
Remove any air bubbles by running a non-metallic spatula or bubble freer down the sides of the jar.
Wipe the jar rims with a clean, damp cloth to remove any food residue.
Place the lids and rings on the jars, tightening the rings fingertip-tight. Do not overtighten the rings, as this can prevent proper venting during processing.
Processing Times for Canned Chili
Processing times vary depending on the jar size and your altitude. It’s crucial to consult a tested recipe from a reliable source, such as the NCHFP, for specific processing times.
General Processing Times (adjust for altitude):
| Jar Size | Processing Time at 0-1,000 ft Altitude | Processing Time at 1,001-2,000 ft Altitude | Processing Time at 2,001-4,000 ft Altitude | Processing Time at 4,001-6,000 ft Altitude | Processing Time at 6,001-8,000 ft Altitude | Processing Time at 8,001-10,000 ft Altitude |
|---|---|---|---|---|---|---|
| Pint Jars | 75 minutes at 10 PSI | 80 minutes at 10 PSI | 85 minutes at 15 PSI | 90 minutes at 15 PSI | 95 minutes at 15 PSI | 100 minutes at 15 PSI |
| Quart Jars | 90 minutes at 10 PSI | 95 minutes at 10 PSI | 100 minutes at 15 PSI | 105 minutes at 15 PSI | 110 minutes at 15 PSI | 115 minutes at 15 PSI |
Altitude Adjustment:
Altitude affects the boiling point of water, which in turn affects the temperature inside the pressure canner. If you live at an altitude above 1,000 feet, you need to increase the pressure or processing time to compensate. Refer to a canning chart from a reputable source for specific adjustments based on your altitude.
Step-by-Step Pressure Canning Process
- Load the jars into the pressure canner. Ensure they are not touching each other or the sides of the canner.
- Secure the lid of the pressure canner and lock it in place.
- Vent the canner by allowing steam to escape for 10 minutes. This removes air from the canner, which can affect the processing temperature.
- Close the vent and bring the canner up to the required pressure.
- Begin timing the processing once the canner reaches the correct pressure. Maintain a steady pressure throughout the processing time.
- Monitor the pressure gauge closely. If the pressure drops below the required level, increase the heat and restart the processing time from the beginning.
- Once the processing time is complete, turn off the heat and allow the canner to cool naturally. Do not force-cool the canner, as this can cause the jars to break.
- Wait until the pressure is completely gone before opening the canner. Check the pressure gauge to ensure it reads zero.
- Carefully remove the lid, tilting it away from you to avoid steam burns.
- Remove the jars from the canner using a jar lifter and place them on a towel-lined surface.
Cooling and Storing Your Canned Chili
Allow the jars to cool completely, undisturbed, for 12-24 hours. As the jars cool, you should hear a popping sound as the lids seal.
Check the seals by pressing down on the center of each lid. If the lid flexes, it is not properly sealed, and the chili should be refrigerated and consumed within a few days, or reprocessed with a new lid.
Remove the rings after the jars have cooled completely. This prevents moisture from accumulating and causing rust.
Wash the jars to remove any residue.
Label the jars with the date and contents.
Store the jars in a cool, dark, and dry place. Properly canned chili can be stored for up to a year.
Troubleshooting Common Canning Problems
Even with careful preparation, canning problems can sometimes occur. Knowing how to troubleshoot these issues can help you ensure the safety and quality of your canned chili.
Jar Breakage
Cause: Jar breakage can be caused by using jars that have nicks or cracks, placing cold jars in a hot canner, or sudden temperature changes during processing.
Solution: Always inspect jars for damage before using them. Preheat jars before filling them with hot chili. Avoid force-cooling the canner.
Siphoning
Cause: Siphoning, or the loss of liquid from the jars during processing, can be caused by overfilling the jars, insufficient headspace, or fluctuating pressure.
Solution: Leave the recommended headspace. Ensure the pressure remains constant during processing.
Lid Failure
Cause: Lid failure, or a failure of the lid to seal properly, can be caused by damaged lids, food residue on the jar rim, or insufficient processing time.
Solution: Use new lids for each canning batch. Wipe the jar rims clean before applying the lids. Ensure you are processing the jars for the correct amount of time at the proper pressure.
The Importance of Using Tested Recipes
Using a tested recipe is essential for safe home canning. Tested recipes have been scientifically evaluated to ensure that they provide adequate heat penetration to kill harmful microorganisms.
Reliable Sources for Tested Recipes:
- National Center for Home Food Preservation (NCHFP)
- Your local extension office
- USDA Complete Guide to Home Canning
Avoid using untested recipes found online or in old cookbooks, as they may not provide adequate processing times and can lead to foodborne illness.
Beyond the Basics: Adding Your Own Touch
While following tested recipes is crucial for safety, you can still add your own personal touch to your canned chili. Experiment with different spices, peppers, and vegetable combinations to create a flavor profile that you love.
Be cautious about adding ingredients that can alter the acidity of the chili. Adding too many low-acid ingredients, such as extra beans or vegetables, can make the chili unsafe for canning. If you want to add additional ingredients, consult a canning expert or use a tested recipe that includes those ingredients.
Consider using different types of meat, such as venison, ground turkey, or shredded chicken. Just be sure to follow the recipe’s instructions for preparing the meat before adding it to the chili.

Why is proper processing time crucial for canned chili?
Proper processing time is absolutely essential when canning chili at home to eliminate the risk of botulism. Botulism is a severe and potentially fatal illness caused by the bacterium Clostridium botulinum, which can thrive in low-oxygen, low-acid environments like improperly canned foods. These bacteria produce a dangerous toxin that affects the nervous system.
The heat applied during the canning process destroys Clostridium botulinum spores. The processing time depends on jar size, the density of the food, and your altitude. Insufficient processing can leave viable spores, leading to toxin production over time, making the canned chili unsafe to consume. Always adhere to tested and approved recipes and processing times to ensure food safety.
What factors affect the processing time for canned chili?
Several factors directly influence the appropriate processing time for canned chili. These include the jar size (pint or quart), the recipe's ingredients (especially the amount and type of acid), and the method of canning (pressure canning versus water bath canning). Importantly, pressure canning is the only safe method for canning chili because it achieves the high temperatures necessary to kill botulism spores.
Altitude is another critical factor. As altitude increases, the boiling point of water decreases. This means lower temperatures are achieved during water bath canning, making it ineffective for low-acid foods like chili. In pressure canning, you must increase the pressure based on your altitude to ensure adequate heating and destruction of harmful bacteria. Always adjust your processing time or pressure according to your specific altitude.
Can I use a water bath canner for chili?
No, you cannot safely use a water bath canner for processing chili. Chili is considered a low-acid food, meaning its pH level is above 4.6. Clostridium botulinum, the bacteria responsible for botulism, can survive and produce toxins in low-acid environments, especially when canned.
Water bath canning only reaches a temperature of 212°F (100°C) at sea level, which is insufficient to kill botulism spores in low-acid foods like chili. Pressure canning, on the other hand, reaches temperatures of 240°F (116°C) or higher, destroying these spores and ensuring the chili is safe to eat. Therefore, pressure canning is the only recommended and safe method for canning chili.
What pressure should I use when canning chili in a pressure canner?
The correct pressure for canning chili in a pressure canner depends primarily on your altitude and the type of pressure canner you are using (weighted gauge or dial gauge). Weighted gauge canners typically operate at 10 psi or 15 psi, while dial gauge canners offer more precise pressure settings.
For altitudes at or below 1,000 feet, use 11 psi with a dial gauge canner or 10 psi with a weighted gauge canner. For altitudes between 1,001 and 2,000 feet, use 12 psi with a dial gauge canner or 15 psi with a weighted gauge canner. Adjust the pressure further for higher altitudes, consulting a reputable canning guide for specific recommendations based on your location. Precise pressure is crucial for safe and effective processing.
How long should I process pint jars of chili in a pressure canner?
The processing time for pint jars of chili in a pressure canner varies depending on the specific recipe and your altitude. However, generally, pint jars require less processing time than quart jars due to their smaller size, allowing for faster heat penetration throughout the contents.
As a general guideline, process pint jars of chili for 75 minutes at the recommended pressure for your altitude. Ensure the pressure remains consistent throughout the entire processing time. Always consult a tested and approved canning recipe from a reputable source (like the National Center for Home Food Preservation) for the most accurate and safe processing time and pressure for your specific chili recipe and altitude.
How long should I process quart jars of chili in a pressure canner?
Processing quart jars of chili in a pressure canner requires a longer processing time than pint jars because of their larger size. It takes more time for the heat to penetrate the entire contents of the jar, ensuring the destruction of harmful bacteria like Clostridium botulinum.
Typically, quart jars of chili require processing for 90 minutes at the recommended pressure for your altitude, as determined by your specific pressure canner and elevation. Maintaining consistent pressure throughout the entire 90-minute processing period is critical for food safety. Always refer to a tested and approved canning recipe from a reliable source for the precise processing time and pressure.
What happens if I don't process my canned chili for the recommended time?
If you fail to process canned chili for the full recommended time, you risk incomplete destruction of Clostridium botulinum spores. These surviving spores can germinate and produce the deadly botulinum toxin in the anaerobic (oxygen-free) environment of the sealed jar. The toxin is odorless and tasteless, so you cannot detect its presence by smell or taste.
Consuming chili contaminated with botulinum toxin can lead to botulism, a severe paralytic illness that can be fatal. Symptoms can include blurred vision, difficulty swallowing or speaking, and muscle weakness. If you suspect that your canned chili may not have been properly processed, it is crucial to discard it safely. Do not taste or feed it to anyone or any animal. Boiling the chili for 10 minutes may destroy the toxin, but discarding it is the safest option to prevent illness.
