This recipe elevates classic mac and cheese by incorporating tender tortellini with shell pasta in a rich, creamy sauce. A blend of white Cheddar and Fontina cheeses, enhanced by Dijon mustard, creates a deeply flavorful experience. Finished with a buttery panko topping and fresh chives, it's a comforting yet sophisticated dish perfect for any meal.
For a truly luscious mac and cheese, always shred your own cheeses; pre-shredded varieties often contain anti-caking agents that hinder smooth melting. The combination of white Cheddar and Fontina offers a sharp tang with incredible melt and stretch. Ensure your roux is cooked for at least 2-3 minutes to eliminate any raw flour taste before gradually whisking in the milk to create a silky, lump-free béchamel. Dijon mustard is crucial here, not for its flavor prominence, but as an emulsifier and flavor enhancer for the cheese. Cook your pasta and tortellini al dente, as they will continue to absorb liquid and cook further in the hot cheese sauce. For the panko topping, toast it in a separate pan with butter until golden brown, then sprinkle over, or transfer the finished mac and cheese to an oven-safe dish and broil briefly for a glorious crispy crust. Finish with fresh chives for a pop of color and herbaceous note.
