My favorite thing I’ve been eating lately: is this easy vegan mushrooms and broccoli sheet pan. It’s a dump-everything-on-a-sheet pan kinda recipe and I’m here for it. Low effort, maximum taste. That’s what I call a dreamy dinner. Plus, this easy plant-based roasted vegetables dinner is a healthy, low-calorie meal that’s packed with nutrients, vitamins, and minerals. But it doesn’t taste healthy…it tastes cozy and comforting. A warming plate of tender roasted portobello mushrooms served on a bed of roasted broccoli and golden brown carrots. Just grab a fork and dig in…or scoop up a piece of warm, soft naan, or pita bread and make it into a sandwich.

Ingredients needed to make easy portobello mushrooms dump sheet pan 

Portobello mushrooms – the meaty mushrooms add so much texture and umami flavors to the dish. If you don’t have portobello mushrooms any other type of mushrooms can be used. A combination of larger brown mushrooms, portabellini/chestnut mushrooms, or even baby Bella mushrooms all work well. 

Red onion – cut the red onion into wedges and enjoy the way it softens while roasting in the oven. The edges become almost Caramelized and the onion flavor takes on a hint of sweetness. If you don’t have red onions, regular white or yellow onions will work just as well.

Carrots – smaller-sized carrots add a tender bite and are delicious almost 

Herbs and spices – we’re working with thyme, oregano, salt, pepper, and smoked paprika. If you don’t have smoked paprika, regular paprika will also work.
