Serves 6-8

Ingredients

3 tablespoons butter
1 medium yellow onion, chopped
1 medium shallot, chopped
2 cups asparagus stems
1 tablespoon fresh lemon thyme leaves
4 cups vegetable broth (preferably onion-herb or neutral based)
1 teaspoon lemon zest
1 tablespoon lemon juice
½ cup heavy cream
Salt
Black pepper

Directions

In a large skillet, over medium high heat, add butter. Cook the onions and shallots for a few minutes or until slightly translucent, about 5 minutes. Add the asparagus and sauté a few minutes. Add the lemon thyme and sauté until the asparagus is soft. Add the vegetable stock, lemon zest, and lemon juice and bring to a boil. Reduce to a simmer and cook for 10 minutes. Using an immersion blender, puree into a smooth soup. Slowly blend in the heavy cream. Season to taste with salt and pepper and serve.
