My sister always makes lasagna for Christmas Eve. She usually makes one with beef and one meatless for our brother and herself. This year, she said she's going to use that Impossible meat-like substance, so we'll see how that goes.
I make a really good lasagna (at least my family thinks so). They don't like ricotta, so I only use four ingredients: lasagna noodles, Classico tomato and basil sauce, shredded mozzarella, ground meat (beef or turkey). I just brown the meat, add the sauce and let it simmer. Meanwhile, boil the noodles, drain and let them cool a bit. At this point I would usually shred the cheese, but now I buy it pre-shredded. Life is too short to shred that much cheese. I put a little sauce on the bottom of the lasagna pan. Add a layer of noodles, then sauce, then cheese. Repeat and end with cheese on top. If you want to add ricotta, spread it on the noodles before adding the sauce. Bake it at 350 until it just starts to bubble.
