In a large skillet, brown the ground beef and diced onion over medium-high heat, stirring frequently to break up the meat. Once cooked through, drain any excess fat.

Add the marinara sauce to the cooked beef and onion mixture. Stir thoroughly and let it simmer over medium-low heat until completely heated through.

Preheat your oven to 190°C (375°F). Spread approximately 240 ml (1 cup) of the prepared meat sauce evenly across the bottom of a 23x33 cm (9x13 inch) baking dish.

Carefully arrange four no-boil lasagna noodles over the sauce base, ensuring minimal overlap. Spoon half of the remaining meat sauce over the noodles, then evenly sprinkle half of the shredded mozzarella cheese.
05 -
Place four additional no-boil noodles snugly over the cheese and sauce. Spread the last of the meat sauce over these noodles, then generously scatter the remaining shredded mozzarella cheese across the entire surface, ensuring it reaches the edges for maximum meltiness.

Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 30 minutes.

Remove the foil and continue baking for an additional 15 minutes, or until the cheese is golden brown and bubbly.

Allow the lasagna to rest for 10 minutes before slicing and serving. This crucial step helps the layers set for cleaner, more appealing portions.
