Add the remaining 1 tablespoon oil, onion and mushrooms to the pot. Cook, stirring occasionally, until the vegetables start to soften, 2 to 3 minutes. Add sweet potato, garlic and curry powder; cook, stirring, for 30 seconds. Add broth and scrape up any browned bits. Stir in the beef and any accumulated juices, coconut milk and the remaining 3/4 teaspoon salt and 1/4 teaspoon pepper. Bring to a boil. Reduce heat to maintain a simmer, partially cover and cook until the sweet potatoes are almost tender, about 7 minutes.
