Place the mixture into a loaf pan lined with parchment paper. Make sure to let the parchment paper overlap the loaf pan, so it's easier to remove the lentil loaf once it's done. Bake the vegan meat loaf for 60 minutes at 350°F. Let the lentil loaf cool down for a bit in the loaf pan before serving it.
I highly recommend making the lentil loaf the night before and reheating it on the next day (at 350°F for about 20 minutes). This way it will be much firmer.
