Were your eyes too big for your stomach this past weekend at the farmers' market? This asparagus soup recipe is the perfect way to make use of a surplus of asparagus. Eat it fresh or keep it frozen to enjoy well past asparagus season.
Heat 4 tablespoons of olive oil in a large pot over medium heat. Add the onions and cook, stiring occasionally until transluscent, about 8-10 minutes. Add the asparagus pieces and season with salt and pepper. Cook your asparagus until bright green and tender, about 4-5 minutes. Add the broth and bring to a boil. Add the spinach and cook, stirring occasionally, until the spinach in wilted.
Remove the pot from the heat and let the soup cool. Set a fine mesh strainer over a large bowl. Purée the souop in a blender or food processor until smooth. Strain the soup through the strainer. Stir in the last 2 tablespoons of oil and season with salt and pepper.
