Choosing Your Ingredients

  1. All chilies are not created equal, so you have options when it comes to your chili oil ingredients. While Thai chilies are quite spicy, Ancho chilies will give your oil a smokier flavor. [1] California chilies are very mild, and guajillo chilies have spice with a citrus tang. Make sure you do a bit of research before selecting the chilies you’ll use for your chili oil.
  2. Before deciding which oil to use for this recipe, you should determine that you’ll be using the chili oil for. If you’re going to be cooking with it, it’s great to use more neutral oils like vegetable or peanut oils. However, if you’re going to be using it as a topper for dishes, you might want to select something a bit more flavorful. In this case, a great olive oil or sesame oil can add an interesting flavor.

Heating Your Ingredients

    For this recipe, you’ll want to use a small, heavy saucepan. Set your stovetop to medium heat. For now, you’ll only add this small portion of the oil to the pan. You don't need to get the oil sizzling – in fact, you definitely don't want to heat the oil this much. As soon as the oil is in the pan and the heat is turned on, you can move along to the next step. [4]

    Cook these in the oil, stirring continuously. Don’t walk away from the pan, because it will not take long for the chilies to be ready. Once they start lightly sizzling, you’re ready for the next step. [5]
    • If the chilies turn brown, you’ll need to start over. The key is to heat them up enough so that their flavors will seep into the oil, but not to fully cook them.
  3. Watermark wikiHow to Make Chili Oil
    You’ll want to leave it on the stovetop until the oil is warm, but don’t get it any hotter than that. To see if the chili oil is ready, touch it with your finger. Begin touching the oil as soon as you pour it into the pan, while it is still room temperature. Touch it every thirty seconds or so after that, to avoid allowing it to get hot. As soon as it is warm to touch, remove it from the heat. [6]
    • If you're worried you left your oil on the stove too long and it may have gotten hot, remove it from the heat and let it sit for a bit before touching it with your fingertip. However, you really want to avoid letting it ever get hot.

Storing Your Chili Oil

    As soon as you’ve tested the oil and have confirmed that it’s thoroughly warmed, you’re ready to remove the pan from heat. Let it sit as it cools down to room temperature. [7]

    You can purchase empty airtight bottles at most stores where kitchen supplies are sold. However, you can always clean out an empty bottle you have around the house. Repurpose an old olive oil bottle after thoroughly cleaning it with some water and dish soap.
    • Store chili oil in a cool, dark place. Try a cupboard away from your oven or other heat sources. [8] Chili oil can be stored from about 9 months to one year. [9]
    • Shake your bottle of chili oil sporadically to make sure the chilies are distributed throughout the oil. [10]
  3. If you taste your homemade chili oil right after making it, it might taste pretty mild, but the chilies will continue to release heat after you bottle it up. So your chili oil can get gradually hotter the longer it sits! If you’re pouring it into a stir-fry, make sure you do a quick taste test first. [11]

    Should homemade chili oil be stored in the refrigerator?
    Community Answer
    As long as there are no fresh ingredients in the oil, it should keep just fine at room temperature in a cupboard or on display in your kitchen. For fresh ingredients, I would store it in the fridge, though it should keep fairly well as oil is a preservative.
