Stuffed Portobello Mushrooms with Lentils and Breadcrumbs

Maybe you aren’t vegan, but someone you love is and they are coming over for a holiday dinner? Well, making this vegan stuffed portobello mushrooms recipe says, “Hey, I thought of you, and wanted you to have something delicious to dine on at this gathering.” If this is you and you’re reading this, kudos to you, not vegan person, and your welcoming table! You’re awesome!

These vegan lentil stuffed portobello mushrooms use ingredients that are commonly found in many U.S. kitchens. The lentil filling is loaded with rosemary, sage, breadcrumbs, carrots, leeks and celery.  The portobello mushroom caps are drizzled with balsamic vinegar, and keep the filling moist. They are easy to make and loaded with savory goodness.

These stuffed portobello caps work well as a main dish or side dish. They’re terrific for fall, winter, Thanksgiving, or holiday celebrations. I love topping them with some gravy, like Roasted Garlic Gravy, and just going for it. I hope you love them too!
