This is a hit at potlucks with kids.
12 pieces dry lasagna (NOT the "no-boil" kind)
2 jars of your favorite pasta sauce
1 medium container cottage cheese
1 medium container ricotta cheese
shredded mozzerella, provolone, maybe a little cheddar to make 8-16 oz. - depending on how cheese-y you are feeling.
These are the bare bones ingredients. I usually doctor up the sauce with by sauteing some onions, garlic & mushrooms in olive oil first, and adding some wine or balsamic vinegar.
Mix all the cheeses except for about 4-6 oz of the shredded, with the egg. You could add a little parsley too if you wanted.
Spray 9x13 pan with cooking spray. Ladle in one cup sauce (A 1 cup ladle is a MUST in any kitchen!) Line pan with uncooked lasagna, breaking pieces to fit as necessary. Top with ½ of the of the cheese mixture. Top with 2 cups (approx) of the sauce. Repeat with lasagna, cheese & sauce. Add one more layer of lasagna and sauce and top with reserved cheese.
THIS IS THE KEY TO THIS RECIPE: Spray a large piece of foil with cooking spray. Tightly and completely cover the pan with the foil. You can make ahead and refrigerate at this point.
Bake at 350 for 1 1/4 to 1 ½ hours. Remove foil and broil a couple minutes if you like your cheese browned.
For potlucks - this is a nice non-meat dish that kids love. If just the family is eating - I would add some ground sirloin to the sauce - browning with the onions, etc.
