Dried ancho chiles rehydrated and stuffed with cheese or picadillo, then bathed in a savory sauce. A deeply flavorful family dish showcasing the sweet, smoky character of dried poblano peppers.
Remove stems and seeds from dried ancho chiles. Rinse briefly, then soak in hot water for 20 minutes until softened.
Heat 1 tbsp vegetable oil in a skillet over medium heat. Sauté diced onion and minced garlic until translucent, about 3 minutes. Add ground beef, cook thoroughly, then stir in diced potato, tomato sauce, oregano, cumin, salt, and black pepper. Simmer until the potato is tender, about 10 minutes.
Remove the soaked chiles and pat dry. Carefully stuff each chile with either Monterey Jack cheese or the picadillo filling, taking care not to tear the chiles.
Arrange the stuffed chiles in a baking dish. Drizzle the remaining vegetable oil and pour any leftover sauce from picadillo over the chiles.
Bake uncovered at 375°F (190°C) for 20 minutes, until cheese melts and the chiles blister slightly. Serve hot, bathed in the savory sauce.
