Tips
Source notes using slightly less than 1/4 cup olive oil total
Onion, celery, and carrot can be saved for vegetable broth instead of discarding
Beans should reach stew-like consistency; venting slow cooker lid may take hours to achieve proper thickness
Good to Know
Refrigerate in airtight container for up to 4 days. Freezes well for up to 3 months.
Beans can be soaked overnight. Complete dish can be made 1 day ahead and reheated gently before serving.
Ladle into bowls as a hearty vegetarian main course. Pair with crusty bread and a simple green salad.
Common Mistakes
Do not skip skimming foam after initial boil to avoid cloudiness in broth
Do not overcook mushrooms or they will become mushy instead of tender-firm
Do not add mushrooms to hot oil without moisture or they will brown unevenly instead of sauté evenly
