Ingredients
2 tablespoons butter
1 small onion, chopped
1 stalk celery, chopped
1 medium carrot, chopped
2 medium potatoes, cubed
1 medium butternut squash – peeled, seeded, and cubed(I use roasted squash) and add after the other veggies are sauteed)
1 (32 fluid ounce) container chicken stock
salt and freshly ground black pepper to taste

Directions
Gather all ingredients.

Melt butter in a large pot over medium heat, and cook onion, celery, carrot, potatoes, and squash until lightly browned, about 5 minutes. Pour in enough chicken stock to cover vegetables.

Bring to a boil over medium-high heat. Reduce heat to low, cover pot, and simmer until all vegetables are tender, about 40 minutes.

Transfer soup to a blender and process until smooth. Return to the pot and mix in any remaining stock to reach desired consistency. Season with salt and pepper.
