Grilled Mac and Cheese Sandwich

Steps

1. 1

   Bring a medium saucepan of salted water to a boil and cook macaroni until al dente, 8–10 minutes.

2. 2

   In a small bowl, whisk together flour, mustard powder, garlic powder, salt, black pepper, and cayenne pepper.

3. 3

   Drain pasta. In the same pan over low heat, melt butter, then whisk in the flour mixture and cook until the mixture browns and smells nutty, about 1 minute.

4. 4

   Slowly whisk in milk and cream; cook until the sauce thickens, about 2 minutes. Remove from heat and gradually add cheese, stirring until melted. Fold in the drained pasta.

5. 5

   Line a 9×13-inch baking sheet with parchment or foil; spread the warm mac and cheese on the sheet and smooth. Cover with parchment or foil, buttered or oiled side down, and refrigerate until cool and firm, about 1 hour.

6. 6

   Heat a large skillet over medium-low heat.

7. 7

   In a small bowl, mix together 4 tablespoons (55 g) butter and garlic powder.

8. 8

   Remove mac and cheese from the refrigerator and cut into 8 equal pieces.

9. 9

   Spread 3/4 teaspoon garlic butter on one side of each bread slice. Assemble sandwiches with buttered sides down, a slice of Cheddar, one piece of mac and cheese, and a slice of Jack cheese; top with the remaining bread slices.

10. 10

    Cook sandwiches in the skillet, covered, until the bottoms are browned, about 4 minutes; flip and cook until the second sides are browned, cheese melted, and the mac and cheese heated through, about 4 minutes more.

11. 11

    Repeat with remaining ingredients. Cut sandwiches in half and serve.
