Preparing Peppers and Onions for Canning
Before you start the canning process, you’ll need to prepare your peppers and onions. Here’s a step-by-step guide:
Selecting and Cleaning the Vegetables
- Choose fresh, firm peppers and onions that are free of bruises and blemishes.
- Wash the vegetables thoroughly in cold water to remove any dirt or debris.
- Remove any stems, leaves, or roots, and chop the peppers and onions into desired sizes.
Blanching and Packing
- Blanch the chopped peppers and onions in boiling water for 2-3 minutes to inactivate enzymes and help preserve color and texture.
- Pack the blanched vegetables into clean, hot jars, leaving about 1 inch of headspace.
- Add a brine solution (water, salt, and sometimes lemon juice or vinegar) to the jar, making sure to cover the vegetables completely.
Pressure Canning Peppers and Onions: A Step-by-Step Guide
Now that your peppers and onions are prepared, it’s time to start the pressure canning process. Here’s a detailed guide to follow:
Step 1: Prepare the Canner
- Fill the pressure canner with the recommended amount of water, usually 2-3 quarts.
- Add the canner’s lid and ensure it’s securely locked.
Step 2: Load the Jars
- Place the packed jars into the canner, making sure they’re covered by at least 1 inch of water.
- Close the canner lid and ensure it’s securely locked.
Step 3: Process the Jars
- Process the jars at the recommended pressure and time, usually 10-15 pounds of pressure for 20-30 minutes for peppers and onions.
- Monitor the canner’s gauge and adjust the heat as needed to maintain the recommended pressure.
Step 4: Let the Pressure Drop
- After the processing time is complete, allow the pressure to drop naturally, which can take 30-45 minutes.
- Once the pressure has dropped, remove the canner lid and let the jars cool in the canner for 10-15 minutes.
Step 5: Remove and Cool the Jars
- Carefully remove the jars from the canner and place them on a wire rack to cool.
- Let the jars cool completely, undisturbed, for 12-24 hours before storing them in a cool, dark place.

Can I pressure can sweet peppers and onions together?
You can pressure can sweet peppers and onions together, but it’s essential to follow a tested recipe and canning procedure to ensure the safety of the final product. Sweet peppers and onions have different densities and water content, which can affect the canning process. However, when combined in the right proportions and processed correctly, they can make a delicious and flavorful addition to many recipes.
A good rule of thumb is to use a ratio of 3 parts peppers to 1 part onions. This will help maintain the acidity level of the peppers, which is crucial for safe canning. Make sure to choose a recipe that has been tested for canning and follow the instructions carefully. Also, pay attention to the canning time and pressure, as this will vary depending on your altitude and the type of canner you’re using.
Do I need to roast the peppers before canning?
Roasting peppers before canning is not strictly necessary, but it can enhance the flavor and texture of the final product. Roasting brings out the natural sweetness of the peppers and gives them a smoky flavor. It also helps to remove excess moisture, which can make the canning process safer and more efficient.
If you choose to roast your peppers, make sure to peel and chop them before packing them into jars. You can roast them in the oven or on a grill, and then pack them hot into clean, hot jars. Remove air bubbles, add the recommended headspace, and process the jars in a pressure canner according to the recipe instructions.
What’s the best way to prepare onions for canning?
Onions should be chopped or sliced thinly before canning, and it’s best to use a variety that’s sweet and mild. You can sauté the onions in a little oil or butter to bring out their natural sweetness and softness. This will also help to reduce their volume, making them easier to pack into jars.
When packing onions into jars, make sure to leave the recommended headspace to allow for expansion during processing. Use a clean utensil to remove air bubbles and ensure the onions are tightly packed. Process the jars in a pressure canner according to the recipe instructions, taking into account your altitude and the type of canner you’re using.
How long do pressure-canned peppers and onions last?
Pressure-canned peppers and onions can last for 12 to 18 months when stored in a cool, dark place. The exact shelf life will depend on factors such as the acidity level of the peppers, the canning procedure, and how well the jars are sealed. It’s essential to check the jars regularly for signs of spoilage, such as rust, dents, or swelling.
When storing canned peppers and onions, keep them away from direct sunlight and heat sources. A basement or pantry with a consistent temperature below 70°F (21°C) is ideal. Always check the jars before consuming the contents, and discard any that show signs of spoilage or are past their recommended shelf life.
Can I use a water bath canner for peppers and onions?
It’s not recommended to use a water bath canner for peppers and onions, as this method is not suitable for low-acid vegetables like peppers. Peppers and onions require a higher temperature and pressure to kill off bacteria and ensure the jars are properly sterilized. A pressure canner is the only safe way to can peppers and onions at home.
Water bath canning is better suited for high-acid foods like fruits, pickles, and sauerkraut. If you’re new to canning, it’s essential to understand the different methods and follow tested recipes and guidelines to ensure the safety of the final product. Invest in a pressure canner and take the time to learn how to use it correctly.
What’s the minimum processing time for peppers and onions?
The minimum processing time for peppers and onions varies depending on the altitude, type of canner, and jar size. As a general guideline, you should process pint jars for at least 20 minutes and quart jars for at least 30 minutes at 10 pounds of pressure. However, it’s essential to consult a trusted canning resource, such as the USDA’s Complete Guide to Home Canning, for specific guidelines.
Remember to always follow the recommended processing time and pressure for your altitude and canner type. This will ensure that the jars are properly sterilized and the contents are safe to eat. Never shortcut the processing time or reduce the pressure, as this can lead to spoilage and foodborne illness.
Can I add other ingredients to my peppers and onions?
You can add other ingredients to your peppers and onions, but it’s essential to follow a tested recipe and canning procedure. Some ingredients, like garlic, lemon juice, or spices, can enhance the flavor and texture of the peppers and onions. However, others, like fat or oil, can affect the canning process and safety of the final product.
When adding ingredients, make sure to choose a recipe that has been tested for canning and follow the instructions carefully. Avoid adding any ingredient that can affect the acidity level or density of the peppers and onions, as this can compromise the safety of the final product. Always prioritize safety and follow trusted canning resources and guidelines.
