For an extra layer of flavor, try adding a thin layer of ricotta cheese before the cottage cheese mixture. If you like a little heat, add a pinch of red pepper flakes to the meat mixture. Feel free to experiment with different cheeses. Provolone, Monterey Jack, or even a sprinkle of cheddar would be delicious. This lasagna is best served warm, but it's also great cold the next day! If making ahead of time, cover and refrigerate for up to 3 hours before baking. Increase baking time to 25-30 minutes, or until golden brown.
