Spread softened butter or mayonnaise on the outside of each slice of bread. Mayonnaise might sound surprising, but it creates an ultra-crispy, golden crust thanks to its high oil content.
Heat a nonstick skillet or frying pan over medium heat. Once hot, carefully place the sandwiches in the pan. Use a spatula to press them gently down — this ensures even toasting and helps the cheese melt.
Grill for 3 to 4 minutes per side, or until the bread is a deep golden brown and the cheese is melted to perfection. Don’t rush it — medium heat gives the cheese time to melt without burning the bread.
Tip: If you’re worried about the cheese not melting all the way through, you can cover the pan with a lid during cooking to trap the heat.
4. Let It Rest, Then Slice and Serve
Once your sandwiches are golden and crisp, transfer them to a cutting board and let them sit for a minute or two. This helps the cheese settle and prevents it from spilling out too quickly when you cut it.
Slice each sandwich diagonally (for that classic presentation) or into halves, depending on your preference.
Serve immediately, while still warm and gooey.
Optional Add-Ons for Even More Flavor
Want to take things even further? Try these:
- Add a few basil leaves with the tomato for a Caprese-style twist.
- Use garlic butter on the bread for extra aromatic richness.
- Pair it with a bowl of homemade tomato soup or a light side salad for a well-rounded meal.
- Use a mix of cheeses — like gruyere, mozzarella, or pepper jack — for more variety.
