I meeeeeeean, it’s pretty hard to resist lasagna, am I right? Especially when it’s an easy, vegetarian lasagna recipe that’s hearty, cozy, comforting, and really makes dinner feel special. I decided to dress up this lasagna just a little bit by using meaty mushrooms, warm sage and creamy cheese sauce that takes this to a whole new level. Say hello to this Mushroom Sage Lasagna and try not to lick your screen.

One of the things I love about lasagna is that it can be assembled ahead of time, and baked off right before dinner. Easy dinner ideas are my jam. This vegetable lasagna with white sauce is a nice change of pace from my Vegetarian Spinach Lasagna and my Roasted Cauliflower Vegetarian Lasagna which both use the traditional red sauce.
