Creamed spinach with white sauce is a classic side dish that is rich, creamy, and packed with flavor. Fresh spinach leaves are cooked until tender and then combined with a velvety white sauce made from butter, flour, milk, and seasonings. The dish is finished off with a sprinkle of grated Parmesan cheese for an extra layer of deliciousness. This comforting and nutritious dish pairs well with roasted meats or can be enjoyed on its own as a vegetarian main course.
