Roasted peppers preserved in olive oil are a delicious treat, but how long do they last? The answer depends on a few factors, including the preparation method and storage conditions.
If you're simply storing roasted peppers in olive oil in the refrigerator, they will typically last for about a month. It's important to ensure that the peppers are completely covered in oil, as this acts as a preservative. You can also freeze roasted peppers in olive oil for longer-term storage; this method will keep them fresh for up to a year.
Some recipes for roasted peppers in olive oil include additional ingredients like garlic, herbs, or vinegar, which can affect their shelf life. For example, roasted peppers preserved in olive oil with garlic will only last about a week, while those with added vinegar can be stored for up to three months in the refrigerator or a year if frozen.
To maximise the shelf life of your roasted peppers in olive oil, it's important to follow a trusted recipe and use proper food safety practices during preparation and storage.

How to roast peppers for preservation
Roasted peppers can be preserved in olive oil for up to a year in the freezer or up to three months in the refrigerator. Here is a step-by-step guide on how to roast peppers for preservation:
Step 1: Wash and Dry the Peppers
Before roasting, make sure to wash and dry the peppers thoroughly. This step is crucial as it ensures that the peppers are clean and ready for the roasting process.
Step 2: Prepare the Peppers for Roasting
There are two common methods for preparing peppers for roasting:
- Roasting whole peppers: This method involves roasting the peppers with the seeds, stem, and skin intact. It is suitable for all types of roasting, including oven roasting, grilling, or stove-top roasting.
- Slicing the peppers: For this method, slice the peppers in half lengthwise and remove the core, seeds, and stem. Place the pepper halves cut-side down on a lined baking sheet. This method is recommended for oven roasting and is easier to handle with less mess.
Step 3: Roast the Peppers
There are several ways to roast the peppers:
- Oven roasting: Preheat the oven to 475 degrees Fahrenheit. Place the prepared peppers on a lined baking sheet and roast for about 40 minutes, or until they are soft, puffy, and charred.
- Grill roasting: Place the whole peppers on their sides over a medium-high grill. Turn them occasionally until they are nicely charred all over.
- Stove-top roasting: If you're roasting just one or two peppers, you can use a gas burner on your stove. Adjust the flame to lightly touch the peppers and keep an eye on them, turning as needed, until they are blackened and charred.
Step 4: Steam the Roasted Peppers
Once the peppers are roasted, it is recommended to steam them to make skin removal easier. Place the hot peppers in a bowl and cover with a plate, or use a pot with a lid. Let the peppers steam for about 30 minutes.
Step 5: Peel and Prepare the Roasted Peppers
After steaming, carefully remove the skins, stems, and seeds from the peppers. Avoid running the peppers under water to clean them, as this will wash away the delicious roasted flavour. You can use the peppers right away for various dishes or store them for later use.
Step 6: Store the Roasted Peppers
There are several options for storing roasted peppers:
- Refrigerator storage: Place the peppers in an airtight container and store them in the refrigerator for up to two weeks. Coating the peppers with a little oil can extend their freshness to up to two weeks.
- Freezer storage: Freeze the peppers in a tightly sealed, freezer-safe container for long-term storage. They will stay fresh for up to two months.
- Vinegar preservation: Place the peppers in a jar with salt, vinegar, and pepper juices. This method adds tanginess to the peppers and is suitable for sauces, dips, and soups.
- Preservation in olive oil: Place the peppers in a jar, cover them with olive oil, and store them in the refrigerator. This method can keep the peppers fresh for up to a year in the freezer or up to three months in the refrigerator.

How to sterilise jars for preservation
Roasted peppers preserved in olive oil can be stored in the refrigerator for up to three months. To ensure the peppers last this long, it is important to sterilise the jars before storing them. Here is a detailed guide on how to do this:
- Choose glass jars with airtight lids. Ensure they are free from any cracks or chips and remove any old labels.
- Wash the jars and lids in hot soapy water, then rinse them thoroughly.
- If your jars have rubber seals, place them in a separate small saucepan, cover with water, and boil for 2-3 minutes to sterilise. Dry heat can damage rubber seals, so do not place them in the oven or dishwasher.
- Place the jars upright on a baking tray and put them in a preheated oven at a low temperature (110-140°C) for about 15-20 minutes, or until they are completely dry.
- To sterilise the lids, boil them separately in a saucepan for 5-10 minutes, then place them on a cooling rack or paper towel to air-dry.
- If you prefer, you can also sterilise the jars and lids together in a deep saucepan. Cover them with cold water, bring to a boil, then reduce the heat and boil for 10 minutes. Carefully remove the jars and place them on a lined baking tray to air-dry or pat dry with clean paper towels.
- Alternatively, you can place the jars, lids, and rubber seals in the dishwasher on the hottest cycle, then transfer them to a tray lined with paper towels to air-dry or pat dry.
- Timing is crucial when filling the jars with your preserves. Start preparing the jars when your preserves are about 20 minutes away from being ready.
- Once your preserves are ready, fill the hot jars with the mixture, packing it down to remove any air bubbles.
- Seal the jars with a wax disc and a lid, or secure a cellophane lid with an elastic band.
- If you are making multiple jars, it is a good idea to sterilise one or two extra jars in case you need more than expected.

How to store roasted peppers preserved in olive oil
Roasted peppers preserved in olive oil are a great addition to your kitchen and can be used in a variety of dishes. Here are some tips on how to store them properly to ensure they last as long as possible:
Sterilise the jars
Before you begin, it is important to sterilise your jars. This is a crucial step to ensure the safety of your preserved peppers. Wash the jars and lids with hot, soapy water, and rinse them thoroughly. Place the jars upside down on a baking tray and pop them into an oven preheated to 110°C for about 15 minutes. Make sure to only handle the jars with clean kitchen tongs or oven gloves to avoid any contamination.
Prepare the peppers
Wash your peppers and dry them thoroughly. You can use a variety of peppers, such as bell peppers (red, green, or yellow) or chilli peppers. Cut the peppers in half and remove the seeds and membranes. If you are using bell peppers, you can leave the skin on as it is thin and edible. However, if you are using chilli peppers or prefer to remove the skin, you can roast the peppers and place them in a paper bag to steam, making it easier to peel off the skin.
Roast the peppers
Roasting the peppers is an important step to enhance their flavour and make them softer. Preheat your oven to 180-200°C and arrange the peppers on a baking tray. Drizzle or spray the peppers with olive oil and roast them for about 20 minutes, or until they are tender and slightly charred. You can also grill or broil the peppers if you prefer.
Add garlic and herbs (optional)
For an extra kick of flavour, you can add garlic and herbs to your preserved peppers. Peel and thinly slice a clove or two of garlic. You can also use dried herbs such as oregano, thyme, or rosemary. If you want a spicier kick, add some red pepper flakes or chilli powder.
Assemble the jars
Once your peppers are roasted and any additional ingredients are prepared, it's time to assemble the jars. Place the garlic and herbs (if using) into the bottom of your sterilised jar. Then, layer the roasted pepper strips into the jar, adding more garlic and herbs between each layer. Make sure to leave about an inch of space at the top of the jar.
Cover with olive oil and seal
Pour olive oil into the jar until the peppers are completely submerged. Use a skewer or chopstick to remove any air bubbles and ensure the peppers are fully covered. Wipe the rim of the jar with a clean, damp cloth and secure the lid tightly.
Storage and shelf life
Your roasted peppers preserved in olive oil should be stored in the refrigerator immediately. They will last for about a month in the fridge, possibly longer. The olive oil may solidify and turn cloudy when refrigerated, but this is normal. Simply let the jar come to room temperature, and the oil will return to its clear, liquid state. Always use a clean spoon to remove peppers from the jar, and make sure the peppers are fully submerged in oil before sealing and returning to the fridge.

How long roasted peppers preserved in olive oil last
Preserving roasted peppers in olive oil is a great way to make them last longer. However, it is not a long-term preservation method, and the peppers will only keep for a limited time. Here is a detailed guide on how long roasted peppers preserved in olive oil will last and some tips to ensure their longevity.
The duration for which roasted peppers preserved in olive oil will last depends on various factors, such as storage conditions and the addition of other ingredients. Here is a breakdown of how long you can expect them to remain edible:
- Refrigerated Peppers in Olive Oil: When stored in the refrigerator, roasted peppers in olive oil can last for about a month. The olive oil will solidify in the fridge, but it will become clear again as it returns to room temperature. Ensure that the peppers are always covered with oil.
- Freezing Peppers in Olive Oil: If you wish to extend the shelf life of your roasted peppers, consider freezing them. Freezing is a better option for long-term storage, and the peppers can last for up to a year when frozen.
- Adding Vinegar: Another way to increase the longevity of your preserved peppers is by adding vinegar to the mix. This creates a more acidic environment that inhibits bacterial growth. With the addition of vinegar, your roasted peppers in olive oil can last for up to a year in the refrigerator.
- Pickling Peppers: If you want to explore a different preservation method, pickling is an excellent option. Pickled peppers can be safely stored at room temperature and will last for several months. However, once opened, they should be refrigerated and consumed within a few weeks.
Tips for Preserving Roasted Peppers in Olive Oil:
To ensure the best quality and longevity of your preserved roasted peppers, here are some essential tips to keep in mind:
- Sterilize Your Jars: Before adding the roasted peppers and olive oil, make sure your jars are properly sterilized. This step is crucial for food safety and will help prevent the growth of harmful bacteria.
- Use Good Quality Oil: Opt for standard good-quality olive oil instead of extra virgin olive oil for this preservation method. Extra virgin olive oil is not the best choice for this purpose.
- Keep Peppers Submerged: Always ensure that the peppers are completely covered with oil in the jar. The oil acts as a preservative, so it is crucial to keep the peppers submerged at all times.
- Use Airtight Containers: Store your roasted peppers in airtight containers or jars. This prevents air from entering and causing spoilage. Additionally, use a plastic skewer to release any air trapped in the jar after filling it.
- Add Flavourings: While not necessary, you can enhance the flavour of your preserved peppers by adding ingredients like garlic, thyme, chilli flakes, salt, and pepper. However, if you use garlic, keep in mind that it will reduce the shelf life to about a week.
