When you try these Preserved Chillies in Oil, you will discover their versatility. In fact, such is their ability to add flavour to many dishes, you may in future decide to keep a jar of these on hand at all times. They are also super simple to prepare!
Why we love this recipe:
I have been making this recipe for many years. It originally came from the Italian owner of our favourite pizza restaurant. He had a personal jar of homemade preserved chillies which he brought to our table whenever we dined there. He was delighted that we enjoyed them as his family has been making this condiment for generations and shared with me the method to make them.
There was, of course, no actual recipe, just an outline of what they did, so I interpreted and adapted this and was delighted with the result.
This is a great condiment. I always have a jar on hand as they are perfect for people who like a little warmth with their meals. They are a good accompaniment to meats of all kind, poultry, pizza or pasta.
Ingredients in this recipe:
Long red chillies (cayenne chillies):
I use red cayenne chillies, they are the long, slender variety which generally have a deep warmth without an overt hit. However, the heat will depend on the variety that you choose.
The heat of the Preserved Chillies in Oil does seem to vary according to the seasons, but even when they are very mild, they add a beautiful flavour. If you prefer very hot chillies you may like to add a couple of fiery, smaller chillies to your mixture.
For the vinegar brine, I use coarse kitchen salt, not fine table salt. This may also be known as kosher salt.
Distilled white vinegar is often recommended for pickles and preserves. However, you can also use white wine vinegar. They each will have an acidity content of around 5% and when combined with the salt assist in the preservation of the chillies. For this recipe, we do not recommend apple cider vinegar as it has a lower acidity level.
Do not use vinegar which is specifically sold for cleaning purposes; it has a much higher acidity content and is not intended for culinary purposes.
Extra virgin olive oil:
I prefer to use extra virgin olive oil for the extra flavour it provides. In addition, it is at the heart of the much-praised Mediterranean Diet being an excellent source of healthy fat and health-benefiting antioxidants.
Step by step instructions:
- To begin, I carefully wash and thoroughly dry the chillies. Then, I remove the stalks and finely slice them, seeds included.
2. and 3. In a non-reactive glass or ceramic bowl, I prepare a vinegar and salt brine, then add the chillies together with their seeds. Ensure that they are covered with the brine, adding more if necessary. Acidic ingredients, such as vinegar, may react with bowls such as aluminium, copper or iron causing the ingredients to discolour and possibly take on a metallic taste.
4. Stir the chillies then cover them with cling wrap and set them aside in their vinegar and salt bath for a minimum of 24 hours. This process removes some of their moisture and assists with the preservation.
5. After that time, drain the chillies and discard the vinegar.
6. Pack the chillies into a sterilised jar and completely cover with olive oil.
Tips for success and FAQs:
Whilst long, red, cayenne chillies are generally of mild-moderate heat, this is not always the case. For this reason, I recommend that you wear food-safe, disposable gloves when handling the chillies. Avoid touching your face or eyes as the active ingredient, capsaicin, can irritate the skin and cause burning. After cutting the chillies, discard your used gloves and carefully wash your cutting board and knife.
It is important to select firm, brightly coloured, fresh chillies. They should have shiny skins without blemishes. Do not select any with wrinkled skin or soft spots.
No, it is important to soak the chillies for at least 24 hours. On occasion, for convenience I have left them in the brine for 48 hours without ill effect. The acidic vinegar and the salt are the preserving agents in this recipe.
For freshness and to maintain good texture and a vivid colour, I prefer to make the batch size as specified and to make a fresh batch as required.
We do not recommend adding any other herbs, spices, garlic etc. to the chillies. Please see the Safety Precautions section below.
To prevent bacteria and the growth of botulism in vegetables, herbs or spices which are packed in oil, the CSIRO (Commonwealth Scientific and Industrial Research Organisation) in Australia has provided advice for commercially produced vegetables in oil. They must not have a pH greater than 4.6. This “can be achieved only by adding acid to the vegetable material”.
For this reason, we soak the sliced chillies in vinegar and salt for a minimum of 24 hours prior to bottling in oil to increase their acidity.
The jar in which the chillies are stored must be sterilised and I have given instructions in the recipe notes.
I store the chillies in a cool, dark location and have kept them for 2-3 months although generally I prefer to make small batches that are consumed within a few weeks. If you prefer, you can keep them in the refrigerator, but the oil will solidify and become cloudy. It does not look attractive but as the oil reaches room temperature it will again become liquid.
When removing chillies from the jar it is important to always use clean utensils.
We have had two batches of our chillies tested by a Government food testing laboratory. The first batch was two days old and registered a pH of 3.21 and the second batch was three months old and registered a pH of 3.28.
I suggest that if you are intending to make the chillies and would like to check their pH you could invest in a pH testing kit.
When it comes to serving:
This recipe for Preserved Chillies in Oil will enable you to enjoy their spiciness all year. It is an easily prepared condiment which is a great addition to many dishes.
I place a bowl of these Preserved Chillies in Oil on the table for many meals. They are delicious served with pizza, pasta, salads, meat, poultry or vegetables.
I serve them with my Greek Chicken and Salsa and Mediterranean Beef Stew, to name a few!
In fact, I have even been known to add them to my breakfast toast with tomato or mashed avocado.

This post was originally published in September 2018. It has been updated with new photos and more information. The recipe remains the same.
Preserved Chillies in Oil
- 200 gm (7 ounces) long red (cayenne) chillies See Notes 1 and 2
- 1 ½ tablespoon (30 g) coarse cooking salt See Notes 3 and 4
- 1 ½ cups (375 ml) white vinegar (5% acidity) See Note 5
- 1 cup (250 ml) extra virgin olive oil See Note 6
For accuracy, we recommend weighing your ingredients. This will produce the best results.
To Sterilise the Jars:
- Choose glass jars with an airtight, metal lid and ensure they have been washed in the dishwasher or by hand in hot soapy water then rinsed well. Check that the metal lids do not have rubber inserts – if they do, allow them to air dry instead of placing in the oven.Preheat the oven to 130 Degrees C (270 F). Place the jars and lids on a baking tray. Heat in the oven for at least 20 minutes, then remove and allow to cool before filling.
To Prepare the Chillies:
- To begin, carefully wash and thoroughly dry the chillies. Then, remove the stalks and finely slice the chillies, seeds included. Do not use any which have blemishes or bruises.
- I recommend that you wear food-safe, disposable gloves when handling the chillies. Avoid touching your face or eyes as the active ingredient, capsaicin, can irritate the skin and cause burning. After cutting the chillies, discard your used gloves and carefully wash your cutting board and knife.
- In a non-reactive glass or ceramic bowl, (see Note 7), prepare a vinegar and salt brine. Combine the two ingredients and stir them well. Add the chillies along with their seeds. Ensure that they are covered with the brine, adding more if necessary, using a ratio of 1 tablespoon of salt for each cup of vinegar.
- Stir the chillies then cover them with cling wrap and set them aside in their vinegar and salt bath for a minimum of 24 hours. Stir once or twice during this time. This process removes some of their moisture, increases acidity and assists with the preservation. (See Note 8)
- After that time, drain the chillies well in a fine sieve, discard the vinegar, pack the chillies into the sterilised jar (see Note 9) and completely cover with olive oil. There will be some air pockets; wait until the oil has settled, you may need to add a little extra.
- Store the chillies in a cool, dark place. The chillies will last for about 3 months, but are best consumed within the first 2 as they soften in texture the longer they sit in the oil.Alternatively, you may prefer to store them in the refrigerator. The olive oil will solidify and become cloudy but will become liquid again when the chillies return to room temperature. For this reason, some readers have used another oil but we prefer the taste of olive oil. Always use clean utensils when removing the chillies from the oil.
- This is the weight of the chillies after the stems have been removed. This is a flexible recipe and can be made to a smaller quantity. Just use the ratio of 20 gm of salt to 1 cup of vinegar for the brine.
- I find that cayenne chillies generally have a mild heat. When I want to increase the heat I add a few of the small, red, very hot chillies.
- Use coarse kitchen salt, or Kosher salt. Do not use table salt; it is finer and the chillies will become too salty.
- The Australian tablespoon is 20 ml or 4 teaspoons. In many other countries the tablespoon is 15 ml or 3 teaspoons. You may have to adjust the measurements accordingly.
- You can use distilled white vinegar or white wine vinegar. They each will have an acidity content of around 5%. For this recipe, we do not recommend apple cider vinegar as it has a lower acidity level. Do not use vinegar which is specifically sold for cleaning purposes; it has a much higher acidity content and is not intended for culinary purposes.
- Always ensure there is sufficient oil to cover the chillies. For 200 gm chillies, and the container in which I stored them, I used 1 cup of oil. Depending on the container, you may need to use a little more.
- Acidic ingredients, such as vinegar, may react with bowls made from aluminium, copper or iron, causing the ingredients to discolour and possibly take on a metallic taste.
- On occasion, for the sake of convenience, I have left the chillies in their brine for more than 24 hours without ill effect.
- To prevent the growth of bacteria, it is essential that the jar be properly sterilised and always use clean utensils when removing chillies from the jar.
- Please note, the nutritional information is based on the entire jar (including the oil). The nutritional information is an estimate only.

Use more salt and high strength white vinegar.It works a charm and my chilies last a year and are fabulous
Hi Mike, thank you for your comments on the Preserved Chillies, I’m so pleased that you enjoy them. 🙂
Can I add chopped garlic to the chillies once they come out of the brine, when i add the olive oil?
We do not recommend adding garlic, herbs etc. to the recipe for safety precautions. Please see the Safety Precautions and Tips for Success sections in the blog post for more information.
Kind regards, Alex
Thank you for the recipe. Ive just made up the salt and vinegar solution and my chopped chillies are soaking. You say cover the chillies but they float? When I make sauerkraut, I use a cabbage leaf and weight to keep the chopped cabbage submerged. I guess it’s not necessary in this case? Kind regards
Once the chillies are in the salt and vinegar cover with cling film and then set them aside to soak.
As noted in step 4, give them a stir a couple of times over the next 24 hours. This will help them be evenly coated in the brine.
Kind regards, Alex
Hi Alexander, they came out amazing! I’m hooked! Thanks
Hi Corrie, I am so pleased that you like the chillies. I do appreciate that you let me know, thank you. 🙂
Hi dear,Thank you very much for your recipe.Can I use coconut oil instead of olive oil.
Hi Chanika, I haven’t tried using coconut oil but I don’t believe it would be suitable as the coconut flavour would dominate the chillies. For this recipe, my preference is olive oil but you could use a flavourless oil, such as grapeseed, if you prefer. 🙂
Hi Dear, It’s really happy to know this recipe. I am a university student and just started cooking. I would like to know about all your recipes and I want to learn the art of cooking.
I have two questions, first is that ‘can we add green chillies in the recipe also’?
and secondly ‘can we add preserved chillies to the dishes while cooking’?
Thanking you in anticipation
Hello Muhammad, I am so pleased that you like the recipe for Preserved Chillies. Yes, you can certainly use green chillies as well as red. You will find many ways to enjoy them and you can add them while cooking if you like. Kind regards, Alex 🙂
Hi! I seem to not have any glass jars of the size I’d like to use for this. Can I substitute a good quality tupperware container or does it really have to be glass? If it does need to be glass, can I use a much larger jar? Like, is that space I’d have at the top a problem? Thanks in advance!
A sterilised glass jar is best. A larger jar won’t be an issue as long as the chillies always remain covered in the oil.
Hi there! Thank you for sharing your recipe with us. I was just wondering if it was necessary for the jars to be sealed, like when making preserves or does the soaking in the vinegar brine prevent chillies from going bad?
Thank you 🙏
No need to seal – just follow our instructions for sterilising the jars and the chillies will last for up to 3 months.
I have made these Chillies numerous times with great success…. Thankyou for this easy recipe… my one bottle had been kept for almost six months without any ill affect on the contents…. I LOVE IT! We use it on anything and everything… delicious with prawns!👍🏻🤗
Hello Ann, thank you for your lovely comments on the Preserved Chillies in Oil. I am so pleased that you enjoy them. 🙂
Linda M Jones
Hi l have a glut of yellow sweet chillis that you can stuff. Do l preserve in the same ways as the others.
Also some scotch bonnets. 😆 l bought plant’s foe normal peppers. Think someone must have changed lables 🤣
Would appreciate feed back as a shame to waste them..
Hi Linda, both types should be fine to use following this method. We always just recommend chopping the chillies so they are all well coated in the vinegar mixture. Let me know how you get on!
Kind regards, Alex
Should the brine be placed in the refrigerator?
No need to place the brine in the refrigerator. We just leave the bowl on the kitchen bench or in a cool location (ie: not in direct sunlight) 🙂
Thanks! I’m in the process of making this recipe today- the chilies are currently soaking. Have you ever boiled the jars to ensure a tight seal for storing? I was hoping to do so as I have many chilies in my garden that I would like to bottle.
That is great! I haven’t ever tried that, no. I wouldn’t recommend keeping for longer than the 3 months anyway, but my concern would be that boiling may alter the texture of the chillies?
Aside from trying this recipe, you could also give my Red Chilli Paste a try – I freeze this, and it is great to add different dishes.
Kind regards, Alex
I’ve never eaten Cayenne chilies and wonder if Jalapenos can be substituted?
That would work just fine. Cayenne chillies can vary in heat but are often a milder kind of pepper and have great flavour – definitely worth a try sometime.

Thank you so much for putting the alternative measurements in your recipe.
I have a glut of red chillis in the garden and will attempt this – it looks very clear and detailed.
Hello Emily, thank you for your lovely comments regarding the Preserved Chillies. How lovely to have a glut of homegrown red chillies? This will be a lovely way to use some. I do hope that you enjoy them. Kind regards, Alex 🙂
