  • 1 lb macaroni 450 g
  • 1 2/3 cups milk 400 ml
  • 1/3 cup all-purpose flour 50 g
  • 1 tablespoon Dijon mustard
  • 2 tablespoons cream cheese
  • 9 oz sharp Cheddar about 3 cups grated/ 250 g, Note 1
  • 2 cans of tuna 6 oz/ 170 g each
  • 1 teaspoon fine sea salt to taste
  • ¼ teaspoon ground black pepper


  • Cook pasta al dente. Drain well. Return to the pot.
  • Meanwhile, grate the cheese, stir the sauce, and drain the tuna while the pasta cooks.
  • Whisk milk, flour, mustard, salt, and pepper in a bowl.
  • Combine: Pour the sauce over the noodles. Heat gently for less than a minute stirring continuously until the sauce thickens slightly (it will happen quickly).
  • Add the grated cheese and stir until the cheese melts. Add the flaked tuna and mix gently.
  • Adjust the taste with salt and pepper and serve immediately.


  1. Don’t use pre-shredded cheese; the anti-caking agents will prevent it from melting properly.
  2. Baked tuna mac and cheese: Preheat the oven to 350 degrees Fahrenheit (180 degrees Celsius) while the noodles cook. Cook the pasta for about 2 minutes less than indicated on the package; it will continue cooking in the oven. Make the sauce and combine the ingredients as instructed. Pour the contents of the pan into a lightly buttered, large casserole dish. Sprinkle with a handful of bread crumbs. Bake for about 15-20 minutes or until golden and bubbly. Let rest for 5 minutes, then serve.
