Brown beef (or ground turkey) in a large skillet until fully cooked. Begin to heat up the tomato sauce in a large pot and add the beef when it is done. Add garlic, oregano, and parmesan to sauce
Stir the sauce regularly for about 1.5 hours on very low heat until it thickens. You can continue to add more garlic, parmesan, and oregano to taste if needed.
Begin to boil the noodles when the sauce is almost done. When all the noodles and sauce are cooked, it’s time to start layering the lasagna.
Here's how to layer: Sauce at bottom of dish to prevent sticking. 3 noodles side by side. Layer in the cheese over the noodles (peel apart the provolone and sprinkle the mozzarella). Dribble the sauce on top and spread evenly with spatula. Cover the layer with grated parmesan. Repeat until completed and push down the noodles with a spatula to make it thicker and to distribute the sauce throughout. You’ll have about 4-5 layers of noodles. The final layer is sauce topped with grated parmesan
Put the lasagna in the oven at 375F (Covered in foil) for about 45 minutes and monitor from there.
