Lasagna is a wide, flat pasta noodle, usually baked in layers in the oven. Like most Italian dishes, its origins are hotly contested, but we can at least say that’s its stronghold is in the region of Emilia-Romagna, where it transformed from a poor man’s food to a rich meal filled with the ragù, or meat sauce.
Preheat oven to 350 degrees F (175 degrees C)
- Bring a large pot of lightly salted water to a boil. Add the lasagna noodles and olive oil; cook until al dente, 8 to 10 minutes; drain.
- Cook the ground beef and sausage in a large pot over medium heat; drain. Stir in the mushrooms, garlic salt, oregano, thyme, basil, and tomato sauce. Season with salt and pepper; simmer 30 minutes.
- Meanwhile, mix together the ricotta cheese, eggs, and Parmesan cheese in a bowl.
- Ladle enough of the meat sauce into a 9×13 inch baking dish to cover the bottom in a thin layer. Form a layer atop the sauce with 3 of the lasagna noodles. Spread about 1/4 of the ricotta cheese mixture over the noodles. Sprinkle about 1/3 of the mozzarella cheese over the ricotta cheese mixture and then ladle about 1/3 of the meat sauce over the mozzarella cheese. Repeat layering twice more, topping with the remaining 1/4 pound of mozzarella cheese.
- Bake in preheated oven 90 minutes. Allow to sit 10 to 15 minutes before serving.
