Brown Italian sausage and ground beef in a large skillet. Drain and set aside Tip: sausage will take longer to brown than ground beef
While meat is being browned, mix ricotta cheese with egg and beat well.
Boil noodles in a large pot. There are no-boil noodles but I haven't tried them yet
Ladle 2 cups of sauce into your pan and coat whole bottom and up the sides
Take lasagna noodles and lay out over sauce. I used about 5-6 horizontally and 2 vertically.
Take about a cup of ricotta cheese and with a knife or back of spoon spread it on top of your noodles.
Sprinkle Mozzarella cheese over ricotta cheese. Optional: add Parmesan/Romano cheese as well in a light sprinkle
Sprinkle sausage/beef over cheese
Add more sauce over meat combo
Cover this layer with more noodles
Repeat process until pan is filled almost to top. I did three layers.
Cover top layer with Mozzarella (also Parmesan/Romano if wanted)
Bake covered for 30 mins, uncover and bake an additional 15 mins until bubbly and lightly browned on top.
It is honestly easier to go ahead and make two pans of lasagna at the same time. You can bake both and then freeze one for dinner next week. Just double the ingredients (you will probably have leftover noodles)
