- Once your peppers are sliced, heat the oil in a large frying pan over medium-high heat. You can use olive oil, coconut oil, or another type of cooking oil to fry them.
- When your oil is hot, add your sliced peppers to the pan and let them cook for about 2-4 minutes, stirring frequently. If really necessary, adjust the heat so that you maintain a steady sizzle but don't risk burning them.
- Once the peppers have cooked for a few minutes and started to soften, toss in the chopped garlic and salt and continue cooking for another minute or two until everything is cooked through and seasoned to taste. Then you're ready to enjoy it!
- Garnish with fresh herbs like cilantro or parsley if desired, and serve this dish alone as a side dish or as part of an Asian-inspired meal with noodles or rice on the side.

How To Make Chili Oil using Thai Peppers
Ingredients
- 10 each Thai Peppers / Chilis
- 1 cup Olive Oil
- 15 cloves Garlic
- 2 sprigs Cilantro
Instructions
- Start by removing the stems of your Thai peppers.
- Next, slice your peppers into thin pieces, creating strips or thin discs. These thin pieces will allow the chili to cook evenly in the pan.
- Once your peppers are sliced, heat the oil in a large frying pan on low heat (do not let the oil smoke). You can use olive oil, coconut oil, or another type of cooking oil to fry them.
- You should use the smallest hob on your stove, at the lowest temperature. This will allow the oil to get flavored, while the chilies and garlic cook.
- When your oil is hot, add your sliced peppers to the pan and let them cook for about 2-4 minutes [depending on the size of the peppers and strength of hob used], stirring frequently. The oil will create light bubbles while the water is released from the peppers.
- Once the peppers have cooked for a few minutes and start to soften, toss in the chopped garlic and salt and continue cooking for another 2-3 minutes, or until the garlic's rawness has gone and it has started to turn golden brown.
- Garnish with fresh herbs like cilantro or parsley if desired, and serve this dish alone as a side dish or as part of an Asian-inspired meal with noodles or rice on the side.

5 min is too much time and the pepers will be burnt. Also one location you write one cup of olive oil, another place few table spoons, not sure what it should be

Hi Yoram,
Thank you for spotting that - yes, the correct amount is the one in the ingredients in the recipe card, and have fixed it.
I have added a few notes to make the recipe clear; the hob used should be the smallest on your stove and on the lowest heat setting; this will allow the peppers and garlic to infuse the oil while cooking extremely slow. The oil will lightly sizzle as the water from the veggies is eliminated, but these will slowly turn golden brown as they are cooked.
If you look at the image in the recipe card, you can notice how the color of the oil changed too - this happens because the whole dressing was cooked very slow, and my chopped garlic is golden-brown. I hope this helps!
