Well, making this recipe for vegan stuffed portobello mushrooms with lentils and breadcrumbs 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!

These vegan lentil stuffed portobello mushrooms use ingredients that are commonly found in many U.S. kitchens. The filling uses dried rosemary, dry rubbed sage, carrots, celery, leeks and breadcrumbs. The portobello mushroom caps are drizzled with balsamic vinegar, which not only add to the flavor, but also keep the filling moist. They are easy to make and taste like savory goodness.

These vegan stuffed portobello mushrooms 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!
