Caprese Panini

Ingredients

• 28 g (2 tablespoons), at room temperaturebutter
• 4 slicesItalian or sourdough bread
• 113 g (4 ounces), slicedfresh mozzarella
• 1 large, slicedtomato
• to tastesalt and black pepper
• 60 ml (4 tablespoons)homemade pesto
• 5 ml (1 teaspoon)balsamic reduction

Instructions

1. 1

   Butter the bread

   Butter the outer sides of two slices of bread, covering the surfaces generously.

2. 2

   Fill the sandwiches

   Spread pesto over the unbuttered sides. Layer on thick slices of mozzarella and tomato, season the tomato with salt and pepper, then add a little balsamic reduction. Close each sandwich with the remaining bread.

3. 3

   Preheat the press

   For a panini press, grease it with oil, close the lid and preheat. If there is no indicator light, allow about 5 minutes for it to heat.

4. 4

   Press and toast

   Put a sandwich in the press, lower the lid and apply pressure with your hand. Cook for about 5–7 minutes, checking periodically, until the bread is evenly golden and the cheese has melted.

5. 5

   Heat a pan

   For stovetop cooking, use a non-stick grill pan for classic marks, or use a regular pan. Set it over medium heat and add the sandwich.

6. 6

   Cook both sides

   Cook the first side for about 3 minutes, then turn the sandwich when it is golden. To press it as it cooks, place heavy cookware on top, such as a cast-iron skillet or a large, heavy mixing bowl. A baking sheet and pressure from your hand can also be used. Cook the second side for another 2–3 minutes.

What is a Caprese panini?

Caprese takes its classic Italian pairing of tomato, mozzarella and basil and puts it between slices of bread for a warm sandwich. This version adds pesto for a concentrated basil flavour and balsamic reduction for a sweet-tart accent.

Toasting the buttered bread while pressing the filling gives the sandwich its crisp exterior and soft, melted centre. It is an easy way to turn familiar summer ingredients into a substantial lunch.

Nutrition and macros by portion

The nutrition label shows one serving as written: 630 calories, 18g protein, 29g carbs, 49g fat.

The bread supplies most of the carbohydrates, while butter and pesto contribute much of the fat. Mozzarella provides protein, alongside additional fat; serve the panini with a generous portion of salad or vegetables to balance the plate.

Choose bread that holds together

Bread choice: Italian bread or sourdough both work here. Choose slices sturdy enough to hold the juicy tomato and cheese while being pressed.

Butter: Spread it across the entire outside surface of the bread so the sandwich can toast evenly. Keep the pesto on the inside.

Layer for a balanced filling

Mozzarella: Slice it thickly and distribute it across the bread so it warms and softens throughout the sandwich.

Tomato: Add the salt and pepper directly to the slices, as the method specifies. A little balsamic reduction adds flavour without overwhelming the fresh ingredients.

Get an even press

Panini press: Preheat it fully before adding the sandwich; if there is no indicator light, allow about 5 minutes. Lower the lid and apply pressure with your hand as the recipe directs.

Stovetop: A grill pan gives the bread marks, but a regular pan works too. Use heavy cookware to press the sandwich while the second side cooks.

Look for these doneness cues

Bread: Aim for an even golden colour rather than relying only on the clock. Check periodically during the press's 5–7 minutes of cooking.

Cheese: The mozzarella should be melted and soft. On the stovetop, the first side takes about 3 minutes and the second side about 2–3 minutes.

Serve while warm

Let the panini come off the press or pan once the outside is crisp and the filling has melted. Serve it warm so the contrast between toasted bread and soft mozzarella is at its best.

A simple green salad or a bowl of vegetable soup can round out the meal without competing with the pesto and balsamic flavours.

Recipe notes & tips

• Bring the butter to room temperature so it spreads easily over the bread.
• Spread pesto on the unbuttered sides to keep it inside the sandwich.
• Season the tomato slices before closing the sandwich.
• Preheat the panini press for about 5 minutes if it has no indicator light.
• Check the sandwich periodically so you can stop once the bread is golden and the cheese has melted.

Variations

• Use sourdough: Choose sourdough slices for a tangy contrast with the pesto.
• Add extra basil: Layer fresh basil leaves with the tomato and mozzarella.
• Adjust the balsamic: Use a little less reduction for a subtler sweet-tart note.
• Try a regular pan: Cook without grill marks if you do not have a grill pan.
• Change the bread: Use Italian bread in place of sourdough for a milder flavour.

Common mistakes to avoid

• Uneven buttering: Cover the outside of each slice so the bread browns consistently.
• Pesto on the outside: Spread it on the unbuttered inner surfaces to keep the exterior ready for toasting.
• Skipping the preheat: Heat the press before adding the sandwich for more even cooking.
• Cooking without checking: Look in periodically and use the golden bread and melted cheese as cues.
• Pressing too lightly on the hob: Place heavy cookware on top while the second side cooks.

How to store

These paninis are best eaten warm soon after cooking. If needed, refrigerate leftovers in a covered container for up to 2 days and reheat in a pan or panini press until hot and crisp; the bread may soften in storage.
