• Starting in a cold pan, brown the ground beef, sausage and onion. Starting from a cold pan will help the fat in the meats to render. Add the tomato (marinara) sauce and let it cook for 1-2 hours.
• Combine all the cheese filling ingredients and set aside.
• Boil the lasagna noodles following package instructions. I cook it to barely al dente. When the noodles are done, drain and put them in cold water until ready for use.

Assembling & Cooking the Lasagna

• Divide the meat sauce into 4 parts, noodles into 3 parts, and cheese filling into 2 parts.
• Ladle 1/4 of the meat sauce onto the bottom of a 9"x13" baking dish or a lasagna pan (10"x15").
• Layer 1/3 of the noodles in an overlapping fashion on top of the meat sauce.
• Spread 1/2 the cheese filling evenly across the noodles. Ladle over another 1/4 of the meat sauce. Add another layer of noodle.
• Repeat the step above.
• After you've topped the lasagna with the final layer of noodle, ladle the last 1/4 portion of meat sauce. Top the lasagne with mozzarella.
• Cover the lasagna with foil (making sure it is not touching the sauce or cheese on top). Bake at 375F for 30 minutes. Remove the foil and continue baking for another 20-30 minutes, or until the cheese is melted and browned to your liking.
• Let cool for 10 minutes before slicing an serve!
