Sheet Pan Mushroom Parmesan is a must-try for Meatless Monday. Portobello mushrooms are stuffed with marinara and mozzarella cheese before being roasted in the oven with grape tomatoes. Top each mushroom with a scoop of garlicky breadcrumbs for an exceptional crunch!
Mushroom Parmesan with Garlicky Breadcrumbs is a vegetarian alternative to traditional chicken parmesan. Made with roasted portobello mushrooms, grape tomatoes, marinara sauce, mozzarella, and topped with crunchy garlicky breadcrumbs, this comforting meal is so much easier than the classic!
While the flavors in this portobello mushroom parmesan recipe are exceptional, there are a few special features I really love:
- It skips the breading process. The stuffed mushroom caps are simply topped with toasted garlic breadcrumbs when they’re done roasting. This way, you can avoid a huge mess in the kitchen!
- No deep frying either! The mushrooms and tomatoes are roasted in the oven to keep everything easy and healthy.
- Roasted portobello mushrooms are meaty and tender. Even meat lovers will love this vegetarian dinner.
This is one of the easiest Italian meals you can make for weeknight dinners or Meatless Monday. You’ll be hooked with each bite of the gooey melted cheese, crunchy breadcrumbs, and meaty roasted mushrooms!
