The first thing to think about when using Dijon mustard in your grilled cheese is what cheese you’ll pair it with. If you want to focus more on the flavor of the condiment, you could go for a mild cheese such as Muenster, Havarti, or Brie. On the other hand, you could pair the strong flavor of the mustard with tangy cheeses like goat cheese or Asiago. Another option could be to pick a mix of various cheeses for added dimension.
The next thing to consider with this pairing is the type of bread you’ll use. For instance, you could use a crusty sourdough to play up the tangy flavors in the mustard. Or, you could go for pumpernickel or rye bread to add other spices and tasting notes to your meal. And, of course, there’s always a buttery brioche, which makes for a rich and decadent grilled cheese without burying the flavor of the mustard.
