Hogao is different from sofrito in one key way: the cooking time. Where a standard sofrito is done in 15 minutes, hogao cooks for 25-35 minutes until the tomato completely breaks down and the scallion loses its pungency and turns sweet. That extra time transforms it from a fresh sauce into something deeper and more savory.
The standard Colombian uses are broad: spoon it over corn arepas (the classic), stir it into white rice during the last few minutes of cooking, use it as a base for beans, top fried or scrambled eggs, or serve alongside grilled meat. It also works as a topping for baked potatoes or as a sauce base for fish.
One combination worth trying: hogao over baked salmon, warm from the oven. The sweetness of the scallion-tomato sauce works well against the richness of the fish. For grilled chicken, spoon hogao over sautéed chicken thighs instead of the usual sauce.
Sofrito uses white onion and is cooked shorter - it has more bite and a fresher flavor. Hogao uses scallion cooked long - sweeter, deeper, more savory. Use sofrito when you want brightness; use hogao when you want body and depth. Both are covered in detail in our guide to sofrito across South America.
Hogao is effectively calorie-neutral as a condiment - the fat is minimal and it adds significant flavor for almost no calorie cost.
Hogao keeps in the fridge for up to a week in a sealed jar. It freezes well - freeze in ice cube trays and transfer to a bag. One cube is roughly 1 tablespoon, enough to sauce one serving of rice or top two arepas. A batch of hogao in the freezer is one of the most useful things a home cook can have.
