Step 1

Preheat oven to 375 degrees. Spray baking dish with cooking spray; set aside.

Step 2

Heat oil in a large skillet or pot over medium high heat. Add in the ground turkey and onions and cook until the turkey is no longer pink, breaking up the turkey meat with a spoon as it cooks. Stir in the garlic and cook for one minute. Add in the tomato paste, oregano and salt, and stir for another two minutes. Pour in the crushed tomatoes and tomato sauce and bring to a simmer. Let simmer for five minutes; set aside.

Step 3

To make the ricotta filling, stir together the ricotta, parmesan, and eggs; set aside.

Step 4

To assemble the lasagna, spoon about half a cup of sauce on the bottom of the baking dish. Place four of the lasagna noodles on top of the sauce, breaking the noodles to fit if necessary. Spread on 1/3rd of the ricotta cheese mixture, 1/4 of the mozzarella, and about a cup of meat sauce. Repeat layers, ending with the last layer or lasagna noodles, sauce, and topping with remaining mozzarella cheese.

Step 5

Cover the lasagna with nonstick foil and bake, covered for an hour. Remove foil and bake for an additional 10 minutes. Let rest for at least 5 minutes before serving.
