This rich and creamy baked pasta dish is loaded with sharp yellow and white cheddar. It uses a homemade cheese sauce infused with grated onion, dry mustard, and a hint of cayenne pepper. Combining both shredded and diced cheeses creates irresistible pockets of melty goodness throughout the casserole. It is perfect for a comforting weeknight dinner or a holiday side dish. The top gets golden and bubbly under the broiler, while the inside stays incredibly creamy.
