Finely chop app the vegetables
Pan-fry onions, chili peppers, butternut squash, and mushrooms. Cook the veggies until they are translucent. Season them with salt, pepper, and oregano.
Then, add tomatoes, tomato puree, and vegetable stock. Simmer the sauce until it is thickened.
Further, prepare the bechamel sauce in another pan. Add butter, flour, and milk to prepare the roux. Mix the roux nicely. Finally, add cheddar cheese to the pan and let the sauce thicken evenly.
Meanwhile, you can put the lasagna sheets to boil.
Take a large oven-proof dish to put together all the elements. Spray the ovenproof dish with the cooking spray. Spread the red tomato sauce into the pan, and pour the bechamel sauce over the red sauce, followed by boiled lasagna sheets.
Repeat the same process for the next layering. Garnish it with cheddar cheese on the top to achieve a creamy and cheesy filling.
Finally, it is time to bake the vegetarian lasagna. Place the dish in the oven and bake the lasagna for 20 minutes at 180 C.
Your Gordon Ramsay style Lasagna is ready.
