Easy Macaroni Tuna Casserole
  1. 1

    Heat the oven to 350 degrees F (175 degrees C) and grease a 2-quart baking dish.

  2. 2

    Bring a large pot of lightly salted water to a boil. Cook the elbow macaroni in the boiling water, stirring now and then, until cooked through but still slightly firm, 8 minutes. Drain and return the macaroni to the pot.

  3. 3

    Stir in 1/4 cup butter, 1/4 cup milk, and the envelope of powdered cheese from the package. Add the mushroom soup, tuna, and 1/2 cup milk; stir to combine. Pour the macaroni mixture into the prepared baking dish and top with the Cheddar cheese and parsley.

  4. 4

    Combine the bread crumbs, 1/4 cup melted butter, and dill in a small bowl; sprinkle over the Cheddar cheese layer.

  5. 5

    Bake in the preheated oven until the cheese is melted and the top is golden brown, about 20 minutes.
