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.
Cooking salt:
For the vinegar brine, I use coarse kitchen salt, not fine table salt. This may also be known as kosher salt.
White vinegar:
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.
Safety precautions:
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 – 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.

Preserved Chillies in Oil
Recipe Measurements:
For accuracy, when weights are provided, we recommend weighing your ingredients. This will produce the best results.
Ingredients
- 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
Instructions
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.

Notes
- 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.

Irina
I had never thought of preserving chillies, but what a great idea! They’re so tasty!
Alexandra
Thank you for the lovely comments, Irina. 🙂
Patricia Broemer
In the ingredients, you have 30 gm. of salt but in the directions you say 20 gm.
Which is correct???
Alexandra
Hi Patricia, they’re both correct – as noted in the recipe card, it is 20 g of salt per cup of vinegar. We used 1 1/2 cups of vinegar, hence 30 grams of salt.
Hope you enjoy the chillies!
Lisvette Rios
Can I use any kind of chilli? Am from Puerto Rico. We have a small chilli here very spicy.
Alexandra
Yes, absolutely. Enjoy.
Veronika
I have 2 questions:
1. How long do you have to let the peppers sit in oil before they’re ready?
2. Do you store them at room temperature or in the fridge?
Thank you!
Alexandra
Hi Veronika, I usually just leave them overnight as I’m always keen to start enjoying them. I store them in a cool, dark cupboard. The olive oil would solidify if they were placed in the fridge. I look forward to hearing how you enjoy them. 🙂
Kahoa Meimuli Corbett
Kia ora, My husband Brendan also using the verge to grow veggies including chillies and we live across the road from the the beach. Heaps of walkers stopping by to check out his chillies when they ready tobe picked. Usually we give some away but for the first time I used this recipe and totally enjoying having the chillies with our meals. Ka pai for the recipe and will use it all time.

Alexandra
Hello Kahoa, thank you so much for your lovely comments. I am delighted to hear that you are preserving your homegrown chillies and how much you enjoy them. Thank you for taking the time to let me know, I do appreciate it. 🙂
Andrew
Can’t live without this one
Alexandra
I’m so happy to hear that Andrew. Thank you so much for taking the time to let us know. 🙂
Sharon Gosling
I grew the mild long red chillies for the first time this year and had two nice crops so far. I used this recipe and it worked very well. Thank you for sharing
Alexandra
Sharon, how lovely to grow your own chillies. There is nothing better than homegrown. I am delighted that you like the recipe, thank you so much for letting me know. 🙂
Alyson Long
Sounds fantastic. I’m about to do this with our millions of birds’ eye chilies. For the brave only!
Alexandra
Using birds’ eye chillies does sound heroic Alyson. 🙂 But I do hope that you enjoy them. 🙂
Tammy White
I love this recipe. Have made it a few times now and am very popular with my friends and family when I do extra to give away. The only thing I change is to use vegetable oil instead of olive oil as it stays liquid in the fridge whereas the olive oil solidifies when refrigerated.
Alexandra
Hi Tammy, I am delighted to hear that you, your family and friends enjoy these preserved chillies. Thank you so much for taking the time to let me know. 🙂
Natalie Foster
super simple and effective;)
Alexandra
Hi Natalie, I am so pleased that you like the preserved chillies. Thank you for letting me know. 🙂
Sophia
Is it normal to have the vinegar smell even after soaking in oil?
I tried using for green chillis. Great method, thanks for sharing!
Alexandra
Hi Sophia! Yes, there will be a slight vinegar smell and taste because of the soaking.
I do hope you enjoy the chilli 🙂
Alfonzo Hawes
Tried it with green chillies (couldn’t find red) and it worked nicely. Will try red chillies shortly and get some more jars to hand out to friends. Can I top up the jar with olive oil as we use it? Thanks.
Alexandra
Hi Alfonzo, I am delighted that you enjoyed the chillies, and they certainly do make lovely gifts. When eating the chillies, if the oil level lowers, I recommend that you top up the oil. (But don’t add any more chillies to the same batch) Enjoy the red ones too!! 🙂
Dee
Hi,
Looking at making this as i have so many left over chilies and don’t want them to go to waste. I have to questions?
1) Can i use organic apple cider vinegar?
2) Once you have done the soaking and now have them in oil can you turn it into paste? blitz them in a blender so you can hide it easier when cooking with children who will eat it if they don’t see it.
Alexandra
Hi Dee, I prefer to use regular white vinegar as it is more acidic and this helps to assist with the preservation of the chillies. After putting the chillies into oil, it would be best to make a paste only as you require it to avoid any bacteria entering. (As you’d be using more equipment eg: blender which is not sterilised). I do hope that you make the chillies Dee and look forward to hearing how you enjoy them. 🙂
Sweetsue
Have gallon bag if big red jalapeños ,that didn’t get stuffed ,in freezer .. don’t want to trash can they be preserved ?
Alexandra
I haven’t tried this method using jalapenos but it should work, although you may prefer to remove their seeds and membrane. To keep the colour and flavour of the chillies I prefer to make a small batch. It is important to soak them in the salt and vinegar brine before covering with olive oil as this helps to preserve them. I do hope that you enjoy the chillies.
Nikki
I am wondering if you sliced some garlic and included them in the brine whether it would help to preserve the garlic and add a garlic flavor to the oil? Have you tried this?
Alexandra
Hello Nikki, I have not tried this but my recommendation would be that you do not add garlic to the oil. It can cause botulism if not preserved carefully. If you would like to have the flavour of garlic with the chillies it would be best to add a little just before serving them. I hope that you enjoy the chillies.
Theresa Wetherill
With this lock down iv turned into a master chef😄 I use huge amounts of chilies and garlic.. but if never soaked chilies as I finish my jar easy too quick. Will be doing the soaking today..
Alexandra
Hi Theresa, soaking the chillies first is an important step. Soaking them in the vinegar brine assists with the preservation of the chillies. I do hope that you enjoy them.
Skye
Hi,
Can I keep topping up the jar with chillies? I’ve got a small chilli bush and we don’t use chilli all that often but I don’t like picking off 5 or 6 small chillies every week and having them go to waste if we don’t use…
Alexandra
Hello Skye, it would not be wise to top up the jar with chillies. Firstly, they need to soak in the vinegar brine and also I would not mix older and younger chillies. This may spoil the jar. You could use the same method to make a very small batch, or, so that your chillies don’t go to waste, you can freeze them, either sliced or whole.
