This lasagna recipe is quick to make and easy to prepare in advance. For a quick weeknight meal, the lasagna can be prepared through step 3, frozen and baked another day, as it will keep in the freezer for up to 1 month. If you decide to do this, just be sure to let your lasagna return to room temperature before baking. This dairy-free ricotta is easy and healthy to make, and it adds just the right amount of texture to the casserole.
