Step 2

Heat oil in a large saucepan over medium heat. Add onion and fennel; cover and cook 5 minutes or until softened. Add creminis, garlic, oregano, salt, and pepper; cook 3 minutes or until creminis release moisture.

Step 3

Stir broth, tomato, sherry, barley, chopped porcinis, and reserved porcini liquid into cremini mixture; bring to a boil. Reduce heat; simmer 10 to 12 minutes or until barley is tender. Divide soup evenly among 4 bowls.
