Potato soup is always popular and, with this creamy sweet potato soup recipe, we are using sweet potatoes rather than regular potatoes. You can use yams instead if you prefer or even a combination of regular potatoes and sweet ones. You might have made baked potato soup or sauteed potato soup before but grilling the sweet potatoes brings the natural sweetness and juiciness to the forefront and gives a great result. The ginger gives this sweet potato soup recipe a hint of Eastern flavor and it contrasts well with the potatoes, adding a nice taste to the soup.

This is a great recipes for outdoor grilled vegetables because the grill also brings out the flavor in the onion and ginger. If you do not like sun-dried tomatoes, you can garnish this soup with some grated cheese or simply just with the fresh parsley. Feel free to adapt this dish any way you like. Substituting ingredients in grilled soup recipes means that you can fine-tune them closer to your personal taste. Perhaps you fancy adding extra cayenne or trying lemon juice instead of the lime juice.

The lime juice counters the sweetness of the sweet potatoes in this potato soup recipe and the cayenne pepper and allspice add a touch of spice, which livens up the recipe and brings out the wonderful fresh vegetable flavors. This is a warming recipe and it is ideal for any season. This potato soup is filling enough for lunch or as an entree. Alternatively, you could serve smaller portions and use it as an appetizer.
