This is the easiest and fastest of all the soups; no simmering time needed. Perfect paired with a salad and herbed bread for a cold winter day.

Combine broth, onion, and potatoes in saucepan. Bring to a boil then reduce heat, simmer for 10 minutes until potatoes are tender, take care not to overcook. Pour 1/2 the mixture in the blender and puree. Return to pot. Make a white sauce in another pan by melting the butter, then adding the flour and mixing until smooth, stir in milk and cream until thick, smooth, and bubbly. Add to potato mixture and season with dill, garlic powder, salt and pepper to taste. Garnish with a small sprinkling of dill and serve immediately.
