Make This Cheesy Brown Rice Casserole In Less Than 30 Minutes!

We like to go vegetarian every once in a while, but we have to make sure that it’s tasty and that it’ll be a dish that actually fills us up, instead of leaving us hungry after an hour. When we do decide to forego meat, this is one of our favorite go-to recipes because it’s delicious and hearty!

Stuffed with brown rice, rich mushrooms and broccoli, and smothered in cheese, this casserole is a force to be reckoned with. You may have some persnickety eaters in your group, some who maybe (think they) don’t like mushrooms, but this dish will show them what they’ve been missing and make a believer out of them, it’s that good! If you want to give a flavorful, filling vegetarian dish a shot, this is the one for you!
