This is a vegan variation of lasagna al forno, a traditional Italian lasagna. It’s the best vegan lasagna you’ll ever have.
This recipe is an enormous amount of work and expensive. I suggest you do it over 3 days. I only make this when someone dies. This is not a casual lasagna recipe.
You can make all the components of this recipe in stages across several days depending on how much distraction you want to create for yourself. The bolognese and béchamel can be in the fridge for 2-3 days, or the freezer for several months. You can also freeze the assembled lasagna for 3 months.
You can double or triple this easily, which is great if you want to have components on hand in case of emergencies.
