Always use 1lb ground beef with 1lb mild italian sausage meat. Use 28oz can of crushed tomatoes. Two cans of tomato paste. Cheese mixture I do a 450g tub of ricotta mixed with 750g tub of cottage cheese. Use oven ready noodles without issue. Don’t always cover it but always set pan on top of a sheet pan in case of spillage. Have been making this lasagna recipe for over 8 years, it is my personal favourite.
