Vegan Stuffed Portobello Mushrooms
Stuffed mushrooms are a mainstay on my Thanksgiving menu. They're easy to make, but I'll admit that I don't always want to stand there and stuff all of those tiny little criminis, when I know I still have to make creamed kale and mashed squash. That's where large portobellos come in.
Not only do these stuffed portobellos come together quickly, they can take center stage on your plate, both impressing your guests and saving yourself some time in the kitchen.
I like to make these stuffed portobello mushrooms for Thanksgiving and Christmas dinner, but they're also a great light meal for just about any day of the week! Because they're loaded with healthy greens and beans, they're almost a complete meal in themselves. Just serve them alongside a salad or a grain, and dinner is served!

This recipe is easy to make!
- First you brush your mushroom caps with olive oil, balsamic, salt and pepper.
- Then you bake the mushrooms in 400°F for 10 to 15 minutes.
- While the mushrooms are baking, you cook the shallots in oil in a pan over medium high-heat for 5 to 10 minutes, or until they've softened and begun to brown.
- Now you add the garlic and rosemary to the pan and cook for another minute or 2.
- Next you add the vegetable stock and spinach to the pan and cook for another 2 or 3 minutes, or until the spinach wilts.
- Remove the pan from the heat and stir in the beans, parsley, breadcrumbs, nutritional yeast and the remaining sea salt and pepper.
