Brown and season the meat. In a large braiser or skillet, heat the olive oil over medium heat. Add the ground beef and italian sausage and break it up into small pieces as it cooks. Once the meat is browned, add in the diced onion, garlic, red pepper flakes, oregano, and basil and cook for 3-4 minutes until the onions are softened.
Simmer the lasagna noodles. Stir in the marinara sauce, water or broth, and chopped basil and bring to a gentle simmer. Season the sauce to taste with salt and pepper. Stir in the broken up lasagna noodles and stir so that the noodles are covered with sauce. Cover, lower the heat to low, and simmer gently for 15 minutes, until the pasta is tender.
Preheat an oven to 400 F.
Make the ricotta mixture. While the noodles simmer, mix together the cottage cheese, mozzarella, and parmesan cheese. Season to taste with salt and pepper.
Bake the skillet lasagna. Uncover the skillet and use a spoon to dollop the cheese mixture over the top. Transfer the skillet to the oven for 30 minutes uncovered, until the cheese is melted and browned. Remove the skillet from the oven and let the lasagna rest for 10 minutes before topping with more basil.
