Tomato Soup: While technically more of a pairing than a condiment, dunking your grilled cheese into creamy tomato soup is a timeless combination that enhances both flavors.
Pesto: Spread a layer of basil pesto inside your sandwich for a burst of herbaceous flavor. The nutty and garlicky notes of pesto complement the melted cheese beautifully.
Hot Sauce: A few dashes of your favorite hot sauce can give your grilled cheese a spicy kick that cuts through the richness of the cheese.
Dijon Mustard: A thin layer of Dijon mustard adds a tangy and slightly spicy element that can elevate the flavors without overpowering the simplicity of the sandwich.
Balsamic Glaze: A drizzle of balsamic glaze inside or on top of the sandwich introduces a sweet and tangy flavor that can elevate the overall taste.
