Homemade Vegetarian Lasagna is one of our favourite meatless meals but let’s face it, it isn’t all that quick or easy to make. So I created this Easy Vegetarian Lasagna Casserole for days when I’m craving the taste and comfort of lasagna but don’t want a lot of hard work.
It does take a bit of time to cut up and roast the vegetables but other than that, this dish is very straight-forward. In fact, I regularly roast a big batch of vegetables all at once and keep them on hand for easy meals so it’s often a case of simply retrieving the roast veggies from the fridge and putting the Easy Vegetarian Lasagna Casserole together.
Use Easily Available Vegetables in This Flexible Recipe
The beauty of this recipe is that you can roast whatever combination of vegetables you have on hand. While my Easy Vegetarian Lasagna Casserole tastes great with eggplant (aubergine) and mushrooms, just one of the two works perfectly well. You can use any combination of coloured peppers depending on what is available at a good price. All you need is a nice big tray of any combination of roasted vegetables and you are all set to go.
You can vary the flavour of my Easy Vegetarian Lasagna Casserole by using different cheeses. I like to combine vegetarian mozzarella-style cheeses with cheddar or sometimes I even add a cheese called Spitfire (similar to Pepper Jack) for a bit of heat.
A Great Vegetarian Dish
Remember that if you want to keep the dish strictly vegetarian, it is important to use a vegetarian cheese. (Many cheeses are made with rennet which is produced using animal by-products.) There is a great variety of vegetarian cheeses made with a vegetarian rennet on the market now so it’s easy to find one (or two or three!) that you like. Equally be sure that your pesto contains a vegetarian Parmesan-style cheese to keep this dish strictly vegetarian.
My Easy Vegetarian Lasagna Casserole is the perfect dish for keen meat eaters because the texture of the roast eggplant and/or mushrooms is so much like meat. It’s a great first dish to try if any members of your family are keen carnivores and you are trying to cut back on the amount of meat you eat.
Serve my Easy Vegetarian Lasagna Casserole with a nice big salad and/or some hot crusty bread or rolls. Leftovers will keep in the fridge for a couple of days and are great warmed up for an easy lunch the next day.
