Featured with this recipe
Grilled cheese sandwiches are a highly requested lunchtime favorite, especially during summer months when the kids are at home. Personally, I get tired of boring grilled cheese, so I decided to create my own, fancier version: the Grown Up Margherita Grilled Cheese Sandwich! The combination of crisp sourdough bread, soft mozzarella, savory pesto, and sweet balsamic vinegar topped with juicy tomatoes is like a party for my taste buds! Plus, it’s a delicious way to use up garden tomatoes during the summer. Grilled cheese is not just for kids anymore!
Ingredients in Margherita Grilled Cheese Sandwich
- Sourdough bread
- Fresh mozzarella slices – sliced thick
- Pesto sauce
- Arugula lettuce
- Balsamic vinegar – a good, aged bottle
Tips for the Perfect “Grown Up” Grilled Cheese Sandwich
- I highly recommend investing in a good bottle of aged balsamic. I recently purchased a REALLY good balsamic and it is amazing the difference between it and the cheap stuff. An aged balsamic is almost like a balsamic reduction, it comes out more thick like a syrup. The taste is incredible and it will last you a really long time!
- If you can’t find a good, thick aged balsamic, you can easily make a balsamic reduction. Just take regular balsamic vinegar and pour desired amount into a small sauce pan. Add about a tablespoon of honey per one cup balsamic vinegar. Simmer and stir until the mixture begins to thicken. Remove from heat and cool.
- Fresh is best! Use fresh mozzarella cheese, fresh tomatoes, and fresh bread. It always makes the best sandwich. If you don’t love sourdough bread, thick slices of French bread, Italian bread, hearty white bread, or even our Honey Whole Wheat bread tastes delicious too.
- You can make your own pesto using our Fresh Homemade Basil Pesto recipe, or buy your favorite brand at the grocery store.
- I like to pile my grilled cheese sandwich high with spicy arugula lettuce, but you can use any lettuce you have on hand, including some fresh basil leaves.
Frequently Asked Questions
For more even browning and overall crispiness, it is better to butter the bread. Buttering the bread gives more flavor to your sandwich, as well as prevents any sticking or burning.
After much research, I can tell you that both do an equally good job. Both mayo and butter make crispy sandwiches with golden brown surfaces. The main difference is the flavor– while the buttered bread tasted more salty and buttery, the bread slathered with mayo had a slight tang. In the end, it comes down to personal preference.

My kids love apple slices and carrot sticks with their grilled cheese sandwiches, but since we’re keeping this lunch a little more “grown up” try a few of these delicious side dishes to round out your meal:
