A comforting and flavorful soup perfect for any season.
Chop the onion, celery, and carrots into small pieces.
Uniformly chopped vegetables ensure even cooking and a smoother texture.
In a large pot, combine the chopped vegetables, split peas, water, salt, pepper, and tarragon.
Layer the ingredients in the pot to distribute flavors evenly.
Bring the mixture to a boil over medium-high heat.
Stir occasionally to prevent sticking.
Reduce the heat to low and let the soup simmer uncovered for 1 hour, stirring occasionally.
Simmering uncovered allows the flavors to concentrate.
Use a blender or hand blender to purée the soup until smooth.
Blend in batches if using a countertop blender to avoid spills.
Return the puréed soup to the pot and heat through before serving.
Taste and adjust seasoning before serving.
