Corn fungus sautéed with onion, chile, and epazote is one of Mexico's most prized ingredients. This vegetarian, healthy dish is a fresh, earthy delicacy packed with protein and nutrients.
Heat 2 tbsp vegetable oil in a large skillet over medium heat until shimmering but not smoking.
Add the diced white onion and cook for 3–4 minutes, stirring occasionally, until softened and translucent.
Add poblano chile (seeded and chopped) and sauté for another 3 minutes, allowing the pepper to soften.
Stir in the huitlacoche and corn kernels. Sauté for 7–8 minutes, stirring gently and ensuring the mixture does not stick or dry out. If needed, reduce the heat to medium-low to prevent burning.
Mix in the epazote leaves and season with kosher salt and black pepper. Cover and cook on low heat for 10 minutes, allowing flavors to meld. Stir once during this time.
Uncover, taste, and adjust seasoning if needed. Serve hot, as a taco filling or side dish.
