Baked Salmon Macaroni and Cheese Casserole
  1. 1

    Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9x13-inch baking dish.

  2. 2

    Fill a large pot with lightly salted water and bring it to a rolling boil over high heat. When boiling, stir in the macaroni and return to a boil. Cook uncovered, stirring occasionally, until cooked through but still slightly firm, about 8 minutes. Drain well in a colander set in the sink. Transfer to a large bowl and stir the softened butter into the macaroni.

  3. 3

    Heat the olive oil in a skillet over medium heat; cook the onion in the oil until browned, about 5 minutes. Stir in the salmon and seafood seasoning and cook until warmed through, about 5 minutes more. Remove from the heat, pour the red wine vinegar into the skillet, and set aside to cool.

  4. 4

    In a large mixing bowl, combine the Cheddar cheese, eggs, milk, and vegetable stock. Add the salmon mixture, peas and carrots, and corn; mix. Stir in the macaroni. Season with salt and pepper. Spread the mixture into the bottom of the prepared baking dish.

  5. 5

    Toast the bread and break it into small pieces. Combine the toasted bread and Parmesan cheese in a food processor; process until chopped into crumbs. Sprinkle over the top of the dish.

  6. 6

    Bake in the preheated oven until heated through, about 45 minutes. Let cool for 15 to 20 minutes before serving.
