I wasn’t trying to reinvent the Caprese sandwich. Unlike my Loaded Sweet Potato Breakfast Waffles and Croffles, where the fun was discovering whether they would waffle at all, I already knew a sandwich would work in a waffle iron. The real question was whether it would be better than a skillet. Was it worth it to pull out another appliance?

After a few rounds of testing, I had the answer. The waffle iron creates an incredibly crisp, buttery crust while pressing all the layers together into one perfect bite. Add ripe summer tomatoes, fresh basil, creamy mozzarella, a little Fontina and Monterey Jack for extra flavour, and a swipe of sun-dried tomato paste, and you’ve got a sandwich that celebrates everything we love about tomato season. It’s a twist on the classic Caprese—and one I think is even better.

If you’re ready to give your waffle iron a new job, here are a few tips that will guarantee a perfectly crisp sandwich every time.

Keys to success in making Waffled Caprese Sandwich

• Use soft white sandwich bread: I tested this sandwich with sourdough, ciabatta and soft white sandwich bread. The soft bread was the clear winner. It created the crispiest crust and the most defined waffle pattern.
• Salt the tomatoes: Sprinkle the tomato slices with kosher salt and let them rest for about 5 minutes before assembling the sandwich. This draws out excess moisture, intensifies their flavour, and helps keep the sandwich from becoming soggy.
• Use fresh mozzarella: For this sandwich, you want fresh mozzarella—the soft, creamy mozzarella packed in water or whey, not the firm block of low-moisture pizza mozzarella. Fresh mozzarella gives you that classic Caprese flavour and creamy texture.
• Fresh mozzarella needs a little help: Fresh mozzarella gives you that classic Caprese flavour, but it’s quite mild. Adding a small amount of a more flavourful melting cheese, like Fontina and Monterey Jack, gives the sandwich more depth and a better melt. Gouda, Havarti, Provolone or even a mild cheddar would all work well too.
• Layer strategically: Spread the sun-dried tomato paste on the bottom slice, then add the fresh mozzarella, tomatoes, basil, and finally the grated cheeses before topping with the pesto-covered slice of bread. Sandwiching the tomatoes between two layers of cheese helps hold everything together, so the filling stays put instead of sliding out with the first bite.
• Don’t skip the garlic butter: Brushing the outside of the sandwich with garlic butter adds another layer of flavour and helps create that beautifully golden, crispy crust that makes the waffle iron shine.
• Don’t rush the resting time: Once the sandwich comes out of the waffle iron, let it rest on a wire rack for 2 minutes before slicing. This keeps the crust crisp and gives the melted cheese a chance to settle so it stays in the sandwich instead of running onto the cutting board.
