Cook both the broccoli and pasta in salted water. Blend a portion of the cooked broccoli with the sour cream and eggs to create a creamy sauce. Then, mix the cooked pasta with the prepared sauce, finely chopped broccoli, and grated cheese. Season with salt and black pepper. Layer the entire mixture into a greased baking dish and sprinkle with an additional portion of grated cheese. Bake at 180°C for approximately 30 minutes.
