Start by heating the olive oil in a large sauce pot or Dutch oven over medium heat. Add in the diced onion and minced garlic, sautéing until translucent.
Add the ground beef and cook until browned, seasoning with salt and pepper.
Stir in Italian seasoning and tomato paste, cooking for an additional 1-2 minutes.
Pour in beef broth, marinara sauce, water, and diced tomatoes. Bring to a gentle boil.
Break lasagna noodles in half and add them, covering the pot to cook for 12-15 minutes.
Once noodles are soft, fold in cottage cheese, mozzarella cheese, Parmesan, and chopped spinach, stirring until everything is combined.
Serve warm topped with cottage cheese and chopped basil.
