ingredients

• 1/4 cup unsalted butter
• 2 cups chopped onion
• 1 cup diced carrot
• 1 cup diced celery
• 1/4 tsp salt
• 1/2 tsp black pepper
• 2 cloves garlic, minced

• 6 cups chicken stock

instructions

–
In a large pot or Dutch oven, melt butter until foaming subsides. Add onion, carrot, celery, 1/4 teaspoon salt and 1/2 teaspoon pepper. Cook until vegetables are softened and just beginning to brown, 5-8 minutes. Add garlic and cook for 1 minute, until aromatic. Stir in split peas.
–
Add ham bone, bay leaf, and 1 teaspoon fresh thyme. Stir in chicken stock and water. Bring to a boil, reduce heat, and simmer uncovered for 60-90 minutes, stirring occasionally, until split peas are cooked down and soup is thickened to desired consistency. (Stir more frequently as the soup begins to thicken and add a little additional stock or water if it gets too thick for your tastes.)
–
Add diced ham during the last 15 minutes of cooking. When ready to serve, remove and discard ham bone and bay leaf, and stir in remaining 1 teaspoon fresh thyme. Season to taste with salt, if needed. Serve hot with croutons and cracked black pepper.
