Easy Lazy Lasagna

Preheat the oven to 350 degrees F (175 degrees C).

Fill a large pot with lightly salted water and bring to a rapid boil. Cook egg noodles at a boil until tender yet firm to the bite, 7 to 9 minutes. Drain.

Heat a large skillet over medium-high heat. Cook and stir ground beef and sausage in the hot skillet until browned and crumbly, 5 to 7 minutes. Drain and discard grease. Pour marinara sauce into the meat. Stir in drained egg noodles, 2 tablespoons Parmesan cheese, onion powder, garlic salt, and Italian seasoning; mix until incorporated. Pour mixture into an 8-inch square casserole dish and top with mozzarella cheese and remaining Parmesan.

Bake in the preheated oven until cheese is golden brown, about 25 minutes.
