Italian Sausage and Mushroom Lasagna with Bechamel Sauce

"The bechamel adds a little something special to this wonderful lasagna. I like to use part skim ricotta and mozzarella and low-fat milk to cut some of the fat in this dish. You won't notice the difference."

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Preheat the oven to 375°F (190°C). Lightly coat a 9x13-inch baking dish with cooking spray.

  2. Cook the Italian sausage in a skillet over medium heat, breaking it up, for about 8 minutes until no pink remains and it reaches 160°F (71°C). Add half the chopped mushrooms and cook 3 minutes more. Drain any fat.

  3. For the bechamel, melt the butter in a saucepan over medium heat. Whisk in the flour for 1 minute, then slowly whisk in the milk, salt and nutmeg. Simmer, stirring, for about 5 minutes until thickened. Remove from heat.

  4. In a bowl, mix the egg, ricotta, dried parsley and half the Parmesan until combined.

  5. Spread a thin layer of marinara from one jar over the bottom of the dish. Arrange a single layer of noodles over it, then spread half the ricotta mixture on top.

  6. Scatter half the sausage and mushroom mixture over the ricotta, add half the mozzarella, then spoon on a little more marinara. Repeat with another layer of noodles, the remaining ricotta mixture, and the remaining sausage mixture with the remaining raw mushrooms.

  7. Spoon the bechamel over the top layer, then cover with the remaining noodles, the rest of the marinara from the second jar, and the remaining mozzarella and Parmesan.

  8. Cover the dish with foil and bake for 40 minutes. Uncover and bake 20 to 25 minutes more until bubbling and the center reaches 160°F (71°C) because of the raw egg.

  9. Let the lasagna rest for 15 minutes before cutting into squares.

Flavor stand-ins for the parsley

How well each one fits the dish's main ingredients (butter, flour, milk, nutmeg, egg, ricotta cheese, sauce):

  1. Cinnamonbetter flavor fit
  2. Parsleythe original
  3. Cardamomabout as good a flavor fit

Fit is the average pairing score against butter, flour, milk, nutmeg, egg, ricotta cheese, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
