Roasted Vegetable Lasagna

Recipe Description

This Roasted Vegetable Lasagna is a delicious Italian inspired option for meat-free Monday. The secret to a delicious veggie lasagna is to roast the vegetables before assembling the lasagne layers. By doing this, you capture the flavor and texture of the veggies without any sogginess.

To make this simple roasted vegetable lasagna, start by roasting eggplants and peppers. As the vegetable roast, make tomato sauce and white sauce. To assemble the lasagna, arrange a layer of the roasted vegetables on the bottom, add a layer of tomato sauce. Top with a layer of lasagna and white sauce. Repeat until you have used all the ingredients. Top with cherry tomato halves and mozzarella. Bake in the oven until bubbling around the edges. Enjoy!
