How to make the mac and cheese part

  1. In order to make this dish, start by boiling water in a medium saucepan. Then, add the pasta and cook for 8-10 minutes or as directed on the package. Remember, you want the pasta to be chewy but also tender.
  2. In a small mixing bowl, combine the flour, mustard powder, garlic powder, salt, black pepper, and cayenne pepper while the pasta cooks.
  3. Drain your pasta in a colander, then set it aside for later. Take the now empty pasta pan and place it over low heat before adding in the butter. Once the butter has melted completely, begin to whisk in the flour mixture. Keep whisking frequently until the overall mixture starts to brown and gives off a nutty aroma; this should take approximately one minute. Make sure you’re watching carefully so that the bottom of your pan doesn’t get scorched during this process!
  4. Gently whisk the milk and cream into the flour mixture until everything is thoroughly combined. Cook until the sauce is hot and just starts to thicken, whisking constantly for about 2 minutes. Remove from heat. Stir in the cheese gradually while stirring constantly with a wooden spoon or silicone spatula until it has melted into the sauce. Then stir in the drained cooked pasta.
  5. Place a 9-by-13-inch (23-by-33-centimeter) rimmed baking sheet on parchment paper or aluminum foil. Spray the paper or foil with nonstick cooking spray or butter it. Warm mac and cheese should be spread on a baking sheet after being cooled. Take another piece of parchment paper and coat it with cooking spray or butter. After that, place the oiled side or buttered side down on top of the macaroni and cheese. Lastly, put it in the fridge until it becomes cool and firm; this process should take around 1 hour.

  1. Preheat a large cast-iron or nonstick skillet over medium-low heat (or use an indoor grill or Griddler).
  2. In a small mixing dish, combine the 4 tablespoons (55 grams) of butter and garlic powder until fully incorporated.
  3. Take the mac and cheese out of the fridge, and peel off the top layer of parchment paper. Cut it into 8 pieces so that each part makes one grilled sandwich. (You can put double layers of plastic wrap around each section and refrigerate for up to 3 days or freeze it for 1 month.)
  4. For each bread slice, spread 3/4 teaspoon garlic butter on one side. Then, take half of the slices and place them buttered-side down on a clean cutting board. For the next layer, top each slice with one piece of Cheddar cheese followed by 1 piece of mac and cheese. (Getting the mac and cheese from the baking sheet onto your sandwich? First, slide a spatula or your hand under each individual serving then flip it over so that it’s facing up.) The final element for this ring is 1 more slice of Jack cheese before topping everything off with another bread slice — this time making sure the buttered side is face UP.
  5. Use a wide spatula to place as many sandwiches in the pan as possible without crowding it. Cover and cook until the bottoms are brown, approximately 4 minutes. Turn and cook the second side until brown, the cheese is melted, and the macaroni & cheese heat through, another 4 minutes or so.
  6. Repeat with the remaining ingredients. Cut the sandwiches in half, if desired, and serve.
