Grilled Mac and Cheese Sandwich

Ingredients

main

  • 0.227 kg macaroni
  • 0.083 cup plain flour
  • 0.75 tsp mustard powder
  • 0.5 tsp garlic powder
  • 0.5 tsp kosher salt
  • 0.5 tsp black pepper
  • 0.125 tsp cayenne pepper
  • 0.085 kg butter
  • 1.5 cup whole milk
  • 1 cup heavy cream
  • 0.455 kg monterey jack cheese
  • 0.055 kg butter (for garlic butter)
  • 1 tsp garlic powder (for garlic butter and bread)
  • 16 pcs bread, square slices
  • 8 pcs mild cheddar cheese slices
  • 8 pcs colby jack cheese slices
  • 0.055 kg butter (extra)

Directions

  • Bring a medium saucepan of generously salted water to a boil and cook pasta until al dente, about 8–10 minutes or per package directions; drain.
  • Whisk together flour, mustard powder, garlic powder, salt, black pepper, and cayenne in a small bowl.
  • Place the empty pasta pot over low heat and melt butter, then whisk in the flour mixture and cook about 1 minute until lightly browned and nutty, watching so it doesn't scorch.
  • Slowly whisk milk and cream into the flour mixture until combined; cook, whisking, until heated and beginning to thicken about 2 minutes then remove from heat.
  • Gradually stir in Monterey Jack cheese until melted, then stir in the drained pasta.
  • Line a rimmed baking sheet with parchment or foil, grease, spread mac and cheese evenly, cover with another greased parchment or foil, and refrigerate until cool and firm, about 1 hour.
  • Heat a large skillet over medium-low.
  • Stir together 4 tablespoons (55 g) butter and 1 teaspoon garlic powder to make garlic butter.
  • Remove mac and cheese from refrigerator, peel off top parchment and cut into 8 equal pieces.
  • Spread 3/4 teaspoon garlic butter on one side of each bread slice. Place half the slices buttered-side down, top each with one slice cheddar, one mac-and-cheese piece, one slice Colby Jack, then finish with remaining bread slices buttered-side up.
  • Place sandwiches in the pan without crowding, cover and cook until bottoms are browned about 4 minutes, turn and cook until second sides are browned, cheese is melted and mac and cheese heated through about 4 more minutes; repeat with remaining sandwiches.
  • Cut sandwiches in half if desired and serve.
