A delightful and creamy soup with a hint of spice, perfect for a cozy meal.
Melt the butter in a large saucepan over medium heat.
Ensure the butter doesn't brown; it should just melt completely.
Sauté the diced onion in the melted butter until translucent.
Stir frequently to prevent the onion from burning.
Sprinkle the flour over the onions and stir well to combine.
This step creates a roux, which will thicken the soup.
Gradually whisk in the milk, ensuring no lumps form.
Warm the milk slightly before adding to prevent curdling.
Add the salt, pepper, diced tomatoes, green chilies, shredded chicken, and Worcestershire sauce to the saucepan.
Stir well to evenly distribute the ingredients.
Reduce the heat to medium-low and let the soup simmer for 15 minutes, stirring occasionally.
Simmering allows the flavors to meld together beautifully.
Serve the soup warm, garnished with fresh cilantro.
Chop the cilantro just before serving for maximum freshness.
