1 recipe Meat Sauce (see Spaghetti* with Meat Sauce recipe)
1 lb lasagna noodles, al dente
3 c. shredded mozzarella
1 c. grated Parmesan
Optional: 1 & 1/2 c. fresh baby spinach, washed, drained & coarsely chopped
Cook Meat Sauce according to directions (somewhere on the blog); allow to simmer for at least 45 minutes.
Meanwhile, in large pot, cook pasta according to package directions.
Preheat oven to 350.
To assemble, use deep 8x10 glass baking pan. Spread a thin layer of meat sauce evenly in the bottom of the pan. Remove pasta from pot with tongs one at a time; add a layer of noodles lengthwise, edges touching, cut to fit if necessary. Spread a layer of meat sauce (1 - 2 c.) over the noodles, top evenly with 1 c. mozzarella & 1/3 c. Parmesan. Repeat two more times. You will now have 3 layers, the top one being cheese.
Bake in oven for 20 minutes.
Remove & allow to sit for 5 - 10 minutes.
Note: If using spinach, top all meat layers except very bottom one with 1/2 c. spinach before adding the cheeses.
Freeze extra meat sauce for later use.
