Step 1

Place lasagna noodles into the bottom of a long pan. Pour hot tap water over the noodles until they are submerged. Let them soak while you prep the lasagna – at least 30 minutes. Agitate the noodles with your hands occasionally to prevent them from sticking together.

Step 2

In a Dutch oven or large pot, brown ground beef, sausage, onion, carrots and celery over medium heat. Add garlic and red pepper flakes and cook 30 more seconds. Drain grease.

Step 3

Add all remaining Bolognese ingredients, cover, and bring to a boil. Remove lid and reduce heat to low. Simmer gently uncovered for 15-20 minutes, stirring occasionally, or until Bolognese is reduced but still saucy.

Step 4

While sauce is simmering, preheat oven to 350 degrees F. Add all of the Cheese Filling ingredients to a large bowl and mix until combined.

Step 5

To assemble, lightly grease a deep 9x13 pan. Spread 1 1/2 cups of meat sauce in the bottom of the prepared pan (layer will be thin). Place 4 noodles lengthwise and part of a 5th noodle on top to cover. Spread with a third of the ricotta cheese mixture. Top with 1 cup mozzarella cheese followed by 1/4 cup Parmesan cheese. Repeat layers (meat, noodles, ricotta, mozzarella, parmesan) 2 more times for a total of 3 complete layers. To finish, top with remaining meat sauce, remaining mozzarella (1 cup) and remaining Parmesan cheese (1/4 cup). (Pan will be very full.) Tent lasagna with foil and secure tightly all around the edges.

Step 6

Place lasagna pan on a baking sheet and bake in preheated oven for 30 minutes. Remove foil, and bake an additional 30 minutes or until hot and bubbly. Let stand 15 minutes before serving. Garnish with fresh parsley if desired.
