Ingredients
  

  • 1 tablespoon olive oil
  • 1 pound sausage meat
  • 1 small onion finely diced
  • 2 cloves garlic crushed
  • 8 ounces mushrooms diced
  • 8 ounces baby spinach
  • 1 teaspoon fennel seeds
  • 1/4 cup butter
  • 1/4 cup flour
  • 3 cups whole milk
  • 1/4 teaspoon ground nutmeg
  • Salt and pepper
  • 2 cups ricotta cheese
  • 3 cups shredded mozzarella divided
  • 8-12 no-boil lasagna noodles
  • 1 cup finely shredded Parmesan cheese

Instructions
 

  • Preheat the oven to 350˚F. Heat a heavy based pot over a medium high heat, drizzle in the olive oil and then add the sausage meat to brown for 5-8 minutes, stirring occasionally and breaking up large chunks.

  • Add the onion, garlic, mushrooms, baby spinach, and fennel seeds to the pot and sauté for another 5 minutes until the mushrooms are browned and the spinach is wilted. Set it aside to cool a little.

  • For the white sauce, in a skillet over medium heat, melt butter, add the flour, and mix until a smooth roux forms, 1 to 2 minutes. Gradually add milk while stirring with a whisk to remove lumps. Continue stirring constantly until the sauce thickens, about 5 minutes. Stir in the nutmeg and season with salt to taste.

  • Now it's time to layer your lasagna. Cover the bottom of a 9-inch square casserole dish with about one-third the white sauce. Add a layer of lasagna sheets, then one-third of the meat mixture. Repeat to make two additional layers.
