In a small bowl combine all the jerk seasoning spices.
In a large stock pot preheated to medium-high heat, melt the butter. Add in the onion, celery, carrot, potatoes, and butternut squash. Saute the mixture until slightly golden, about 6 to 8 minutes, stirring as needed to make sure nothing burns.
Next, add in the jerk-style seasoning spices and toss the veggies with the spices. Allow everything to cook for about a minute or two. Next, pour in enough chicken or vegetable stock to cover the veggies. Bring the mixture to a boil and then reduce heat to low, cover the pot and simmer until tender, about 45 minutes.
You can either transfer the soup to a blender and puree or use an immersion stick to puree the veggies in the pot. Once pureed, check seasoning add salt and pepper if needed. Divide the soup among several bowls and garnish with crispy panko and sour cream.
To make the crispy panko: preheat a small skillet to medium heat. Melt 1 tbsp butter in the skillet. Add in 1/2 cup plain panko and gently stir until the butter is absorbed and the panko turns golden brown for about 3 to 4 minutes.
