Preheat the oven to 375°F (190°C). In a skillet over medium heat, brown the sweet sausage and spicy Italian sausage until no longer pink. Remove from the pan and set aside.
In the same pan, without cleaning, add the olive oil, diced sweet onion, and chopped green onion. Sauté until tender, then add the minced garlic and diced tomatoes. Cook until softened.
Add the tomato sauce and stir well. Let the sauce simmer on low heat, stirring occasionally.
Meanwhile, boil the lasagna noodles according to the instructions on the box. Drain and set aside.
In a mixing bowl, combine the cottage cheese, ½ cup of mozzarella cheese, egg, chopped basil, chopped parsley, and thyme leaves. Stir until well combined.
Take each lasagna noodle and spread a layer of the cheese mixture along its length.
Spread a single layer of the cooked sweet sausage and spicy Italian sausage, followed by a layer of the tomato sauce on the bottom of a ramekin or small oven-safe bowl.
Roll up each lasagna noodle with the cheese mixture inside and place the rolled noodles upright in the ramekin, with the ends facing inward. This will help them stay in place.
Fill any gaps around the lasagna rolls with the remaining cooked sausage, and then pour the rest of the tomato sauce over the top.
Sprinkle additional mozzarella cheese on top of the lasagna.
Bake in the preheated oven for 20-25 minutes, or until heated through and the cheese on top has melted and turned golden.
Remove from the oven and let cool for 10 minutes before serving. Be cautious, as the ramekins will be very hot. Enjoy!
