Ultimate Grilled Cheese

• 12 slices thick-cut bacon, such as Nodine's applewood smoked
• 1 cup good mayonnaise
• 1/4 cup Dijon mustard
• 1/4 cup freshly grated Parmesan cheese
• 1 1/2 teaspoons kosher salt
• 1/2 teaspoon freshly ground black pepper
• 1 white pullman loaf or sourdough bread, sliced 1/2 inch thick (12 slices)
• 6 tablespoons salted butter, at room temperature
• 6 ounces aged Gruyere or Comte cheese
• 6 ounces extra-sharp Cheddar, such as Cabot or Shelburne Farms

1. Preheat the oven to 400 degrees F. Arrange the bacon on a baking rack set over a sheet pan in a single layer and roast for 20 to 30 minutes, until nicely browned.
2. Drain on a plate lined with paper towels and cut in 1-inch pieces.
3. Meanwhile, combine the mayonnaise, mustard, Parmesan, salt, and pepper in a small bowl.
4. Lay 12 slices of bread on a board and spread each one lightly with butter.
5. Flip the slices and spread each one generously with the mayonnaise mixture.
6. Don't neglect the corners!
7. Grate the cheeses in a food processor fitted with the largest grating disk and combine.
8. Distribute the bacon evenly on half the slices of bread.
9. Pile 1/3 cup grated cheese evenly on top of the bacon and top with the remaining bread slices, sauce-side down.
10. Meanwhile, heat an electric panini press.
11. When the press is hot, cook the sandwiches for 3 to 5 minutes in batches until the bread is toasted and the cheese is melted.
12. Allow to cool for 2 minutes.
13. Cut in half and serve warm.
