A grilled panini sandwich is a delightful and easy-to-make meal that combines the flavors of fresh spinach, juicy tomato, and creamy mozzarella or provolone cheese with the aromatic touch of pesto. Perfect for a quick lunch or a light dinner, this sandwich offers a satisfying crunch and a burst of flavors in every bite.
While most of the ingredients for this recipe are commonly found in many households, you might need to pick up some fresh spinach and pesto if you don't already have them. Ciabatta or sourdough bread might also be less common, but they are essential for achieving the perfect texture and flavor in your panini. Look for these items in the bakery and produce sections of your supermarket.
Ingredients for Grilled Panini Sandwich Recipe
Ciabatta: A type of Italian white bread known for its crisp crust and airy texture.
Sourdough bread: A tangy, chewy bread made from naturally fermented dough.
Mozzarella cheese: A mild, creamy cheese that melts beautifully.
Provolone cheese: A semi-hard Italian cheese with a slightly sharp flavor.

Technique Tip for Making Panini
To achieve a perfectly crispy panini, make sure to preheat your panini press thoroughly before placing the sandwich inside. This ensures even grilling and helps the cheese melt uniformly. Additionally, lightly brush the outside of the bread with olive oil or melted butter for an extra golden and crunchy texture.

How to Store or Freeze Your Panini
- Allow the grilled panini sandwiches to cool completely before storing. This prevents condensation, which can make the bread soggy.
- Wrap each sandwich individually in parchment paper or aluminum foil. This helps maintain the sandwich's structure and keeps the ingredients from spilling out.
- Place the wrapped sandwiches in an airtight container or a resealable plastic bag. This ensures they stay fresh and prevents any unwanted odors from seeping in.
- Store the sandwiches in the refrigerator if you plan to eat them within 2-3 days. This keeps the ingredients fresh and the bread from becoming too hard.
- For longer storage, place the wrapped sandwiches in the freezer. They can be stored for up to 1 month without significant loss of quality.
- When ready to eat, thaw the sandwiches in the refrigerator overnight if frozen. This gradual thawing helps maintain the texture of the bread and vegetables.
- Reheat the sandwiches in a panini press or oven at 350°F (175°C) for about 10 minutes, or until the cheese is melted and the bread is crispy. Avoid microwaving as it can make the bread chewy.
- If you prefer a softer texture, wrap the sandwich in damp paper towels before reheating in the microwave for 1-2 minutes. This helps retain moisture and prevents the bread from drying out.
How to Reheat Leftovers
Preheat your oven to 350°F. Wrap the grilled panini sandwich in aluminum foil to retain moisture. Place it on a baking sheet and heat for about 10-15 minutes, or until the cheese is melted and the bread is crispy.
Use a skillet on medium heat. Place the sandwich in the skillet and cover it with a lid. Heat for about 3-4 minutes on each side, pressing down slightly with a spatula to ensure even heating and a crispy exterior.
If you have an air fryer, preheat it to 350°F. Place the panini in the basket and heat for about 5-7 minutes. This method will give you a crispy texture similar to the original grilling.
For a quick reheat, use a microwave. Place the sandwich on a microwave-safe plate and cover it with a damp paper towel. Heat on medium power for about 1-2 minutes. Note that this method may result in a softer texture.
If you have a toaster oven, preheat it to 350°F. Place the panini directly on the rack or on a baking sheet. Heat for about 10 minutes, or until the cheese is melted and the bread is crispy.
Essential Tools for Making Panini
Panini press: A specialized grill that presses and grills the sandwich, ensuring even cooking and beautiful grill marks.

How to Save Time on This Recipe
