You might feel that making lasagne in a pressure cooker is crazy. Don't you need an oven for those crunchy edges? How do you know it is cooked through? How can anyone make lasagne without baking it? Well, trust me - this one is well worth making. If you have a 15cm or 18cm springform tin (or loose based cake tin) and you kept the trivet that came with your Instant Pot®, you can make a delicious layered lasagne in 30 minutes. And if you want to make it ahead, you can prep the lasagne and put it in the freezer, then put it right into the Instant Pot® for an easy dinner.
