Heat a pan over low heat and add 1 cup olive oil, 3 cups chopped onion, and 1 cup chopped green onion. Stir-fry over medium-low heat.

Add 1 cup ground beef to the pan and stir to prevent clumping. Pork can be used as a substitute.

Add 1/3 cup minced garlic and continue stir-frying over medium heat. Allow the moisture to evaporate while stirring.

Once the moisture has mostly evaporated, add 1/2 cup sugar and stir well.

Add 2 cups gochujang and 2 tbsp soy sauce, pouring the soy sauce along the edges of the pan for a caramelized aroma. Mix thoroughly.

Reduce the heat to low and stir-fry for at least 10 minutes to remove excess moisture and deepen the flavor.
