Chili oil is a versatile and flavor-packed condiment that originates from Asian cuisine. It is a vibrant, hot oil that is a result of steeping dried chilies in a base of warm oil. The intense heat from the chilies is infused into the oil, creating a robust and spicy flavor profile. The base oil often used includes vegetable, canola, or sesame oil.

Chili oil's color can range from a bright red to a deeper, more burnished hue, depending on the type of chilies used. It provides a satisfying balance of spicy and slightly smoky flavors, and has a slick, viscous texture which allows it to cling to ingredients for an instant flavor boost.

Used most commonly in Chinese and Sichuan cooking, it is perfect for drizzling over noodle dishes, soups, stir-fries, or even used as a dipping sauce for dumplings. Many bottles of chili oil also contain a sediment of chili flakes at the bottom, adding an extra element of heat and texture when mixed into food. It is also often included in marinades and dressing, offering an extra layer of spice and complexity to dishes.

Chili oil can typically be found in the international or Asian foods aisle of a grocery store. It may also be located in the oils and vinegars section. If you can't find it, ask a store associate for help.
