• Preheat your oven to 375°F (190°C).
• Cook the Pasta: Bring a large pot of salted water to boil. Cook pasta noodles following box instructions. When finished cooking, drain and run cold water over the noodles as they are draining until noodles are cool enough to be handled, This stops the cooking process.
• Prepare the Meat Sauce: In a large skillet over medium heat, cook the chopped onion and ground beef until browned. Drain excess fat. Add marinara sauce, garlic, red pepper flakes, broth, onion powder, salt and pepper. Simmer for 10 minutes.
• Mix the Cheese Filling: In a bowl, combine ricotta cheese, eggs, most of the parsley, 3/4 of the mozzarella cheese, dash of salt and 3/4 Parmesan cheese. Add a teaspoon of sugar here if you want to sweeten up your filling. Mix until well blended.

Assemble the Lasagna

• Spread a thin layer of meat sauce at the bottom of a 9x13-inch baking dish.
• Place 3 or 4 lasagna noodles over the sauce, running the length of the pan.
• Spread 1/3 of the ricotta cheese mixture over the noodles.
• Top with a layer of meat sauce.
• Repeat layers two more times, ending with a last layer of noodles and sauce and a final sprinkle of the remaining Parmesan, parsley and mozzarella on top.
• Bake: Cover with aluminum foil and bake for 50 minutes. Remove foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown.
• Rest: Let the lasagna sit for 15 minutes before slicing. This helps it set and makes serving easier.
