Grilled cheese is already the undisputed champion of comfort food. But when you add a generous layer of basil pesto and a gooey melt of fresh mozzarella, that humble sandwich transforms into a restaurant-worthy masterpiece, but one you can make in under 10 minutes at home.
A Pesto Grilled Cheese with Mozzarella is the perfect marriage of creamy, salty, herby, and crispy. The pesto adds brightness and complexity to the rich, buttery sandwich, while the mozzarella brings that dreamy stretch we all crave.
In this guide, we’ll cover everything: from the best bread to use, how to keep your sandwich crispy (not soggy!), ideal pesto variations, and tasty add-ons that make this sandwich fully customizable and totally unforgettable.
Why Mozzarella and Pesto Are a Perfect Match
1. Complementary Textures
• Mozzarella is soft, mild, and stringy, while pesto is textured and oily—together they balance each other out
2. Bright Meets Creamy
• Pesto’s garlic, basil, nuts, and cheese cut through the fat of the cheese, keeping it from feeling too heavy
H3: 3. Italian Roots
• Both ingredients come from traditional Italian cuisine, making their combo feel natural, nostalgic, and delicious

How to Make the Perfect Pesto Grilled Cheese
Step-by-Step Instructions:
- Choose your bread: Opt for sturdy slices that crisp well and won’t fall apart with pesto moisture.
- Spread pesto: Apply a thin, even layer on the inside of both bread slices. Don’t overdo it—too much pesto can make it greasy.
- Add mozzarella: Layer slices or shredded mozzarella over the pesto on one slice. Add any other fillings you like.
- Assemble the sandwich: Close it up and press down lightly.
- Butter the outside: Use softened butter or brush with olive oil for a golden crust.
- Grill: In a non-stick skillet over medium heat, toast 2–4 minutes per side until golden brown and melty inside.
- Rest: Let the sandwich sit for 1–2 minutes before cutting—it helps the cheese settle and prevents pesto from dripping.

Pro Tips for Sandwich Perfection
• Use low-moisture mozzarella if you’re worried about sogginess
• Toast both sides of the bread before assembling for extra crunch
• Use a press or heavy skillet on top to crisp evenly and melt faster
• Don’t overstuff—too much filling will cause the sandwich to fall apart or cook unevenly
Storage & Reheating
• Store leftovers wrapped in foil in the fridge for up to 1 day
• Reheat in a skillet or toaster oven—not microwave—to preserve crispness
• Pesto can be made ahead and stored in the fridge (4–5 days) or frozen
