Ingredients

  • homemade pasta sheets
  • tomato sauce
  • pesto
  • cream sauce
  • ricotta
  • mozzarella

Instructions

  • Roll the pasta out as thin as your pasta roller will go. Then use the jar (I used 16oz wide mouth pint jars) as a cookie cutter to make your pasta rounds. It takes a ton of rounds to fill a jar. If you make a standard 3 cup flour, 4 egg batch of pasta it will fill 3 jars, and that's WITH re-rolling out the scraps.
  • Before you start building, blanch the pasta rounds in salted boiling water for about 20 seconds. I did this in batches of 10 and built layers of lasagna as I went with each freshly boiled batch. When you're building the lasagna, it will be tough at first to get the rounds into the bottom of the jars to lay somewhat flat. Don't worry about getting it perfect! After about halfway through the jar it will start getting much easier.
  • Start with the pesto between the layers, then about 1/4 of the way, go with the cream sauce and lots of mozzarella. Then for the top 50% do the tomato sauce with mozzarella and ricotta. Go right to the top and pop some extra mozz right on there.
  • *Now lets talk about baking in mason jars. Officially this is not sanctioned by the mason jar people. These jars are however built to withstand pressure cooker sanitizing, so they are fine in the oven as long as you take some precautions. First, you don't want to bake them too hot. I did 325 on these and baked them for 45 minutes. Second, drastic temperature swings are not good for glass. Don't freeze these and then pop them into a preheated oven or you will have some lasagna bombs on your hands! I have read some blogs that say this isn't a big deal, but I personally would highly advise against it. I put these onto a baking dish in a cold oven, then turned the oven on and set the timer for 45 minutes. when I took them out of the oven, I kept them on the baking dish so as not to put them onto a cool surface. I also allowed them to cool for a solid 15 minutes before handling and eating out of. I may be overly precautions, but I have had a few glass baking dishes shatter on me in the past and it's pretty scary.
