Thank you for this great recipe! I teach cooking and this was their favorite tonight. The oven temp was missing so I assume it is 350°F. I also made some clarifications.

Just Enough Lasagne

3 sheets no-boil lasagna
1 Italian sausage
1 ground meat patty (4 oz)
1 small onion, minced
1 tsp minced garlic
1 Tbsp oil
14 oz jar of pasta sauce
1 cup ricotta cheese
1 egg
[dash cinnamon]
1-2 slices of mozzarella or 1/4 cup shredded mozzarella
cooking spray

Equipment:
skillet
loaf pan, 8x4 seems better than 9x5
foil

Preheat oven to 350°F

DIRECTIONS
Remove sausage meat from casing and mix with ground beef, set aside.
In a 10-12” skillet, sauté onion & garlic in oil for 1 minute. Add crumbled ground meat and sausage.
Sauté until all the pink is gone from the meat, about 3-4 minutes. Add 1/4-cup pasta sauce to pan and turn heat down to low. Sauté another minute or two until it looses some moisture. Blend the egg with the ricotta and add cinnamon. Spray the loaf pan with cooking spray and pour a few tablespoons of sauce on the bottom of the pan.
Layer 1 piece of lasagna, a couple of tablespoons of sauce, half the meat mixture, then half the cheese mixture Repeat second layer with another piece of lasagna then more sauce, then the meat & cheese mixture. Top with last slice of lasagna, sauce and mozzarella.

Bake covered with foil for 45 minutes. Remove foil cover last 5 minutes to brown.
Let stand 8-9 minutes before serving.
Great reheated.
