Velvety smooth and packed full of luscious flavor, this curried sweet potato soup is ideal for cozying up to on cold nights. Bell peppers and onion are roasted alongside the sweet potatoes to draw out their natural sweetness, and then all the veggies are tossed in a blender with curry powder, red pepper flakes, garlic, and apple cider vinegar for a touch of acidity. If you have a high-speed blender, you can heat the soup on your blender’s soup setting and skip reheating it in a pot. Once the soup is ready to serve, top each bowl with crunchy pumpkin seeds for some nice textural contrast, and dig in.
