Sun-Dried Tomato Pesto Cheese

I discovered this sandwich on a Wednesday afternoon when my pantry was practically bare except for a jar of sun-dried tomato pesto I'd been saving for something special. The smell of butter hitting the hot skillet paired with that tangy, rich pesto aroma made me stop mid-bite of the first one—this wasn't just lunch, it was a moment. Now whenever I make it, I'm transported back to that realization that sometimes the simplest combinations create the most memorable flavors.

I made this for my sister one rainy Sunday when she stopped by unannounced, and she ate hers so quickly she asked for seconds before I'd even sat down with mine. Watching someone genuinely light up over something you've just made from basically nothing—that's the real satisfaction here.

Ingredients

• Bread: Choose something with enough structure to handle the butter and cheese without falling apart—sourdough gives you tanginess that plays beautifully against the pesto, while whole wheat adds earthiness.
• Sun-dried tomato pesto: This is your flavor anchor, so pick one you'd actually eat by the spoonful; the quality difference between brands is genuinely noticeable.
• Mozzarella cheese: Fresh mozzarella melts more evenly than pre-shredded, but if you're using shredded, a good quality one will still give you that creamy pull you're after.
• Butter: Unsalted lets you control the salt level, and it creates that golden, nutty crust that makes this sandwich sing.

Instructions

Prep your canvas:

Spread a tablespoon of sun-dried tomato pesto on one side of each bread slice—don't be shy with it, this is where all your flavor lives. The pesto should coat the bread evenly so every bite gets that concentrated, briny richness.

Build the sandwich:

Lay both slices pesto-side up, then layer the mozzarella on just one slice. Place the second slice on top so the pesto sides are facing the cheese, creating a pesto-cheese-pesto situation that's basically flavor insurance.

Get your pan ready:

Heat your skillet over medium heat and add the butter, watching it melt into that foamy, golden state that means it's ready. This is your visual cue that the temperature is perfect for achieving golden bread without burning.

The sear:

Once the butter is singing, place the sandwich in the skillet and let it cook undisturbed for 3 to 4 minutes until the bottom is deep golden brown. Resist the urge to move it around—that contact time is what creates the crust.

The flip:

Using a spatula, carefully flip the sandwich and cook the other side for another 3 to 4 minutes, pressing down gently with the back of the spatula to help the cheese melt and the bread make contact with the pan. You're listening for that gentle sizzle and watching for that second side to turn golden.

The finish:

Remove the sandwich from heat and let it rest for a minute—this gives the cheese a moment to set slightly so it doesn't spill out everywhere when you cut it.

Save to Pinterest

There's something quietly powerful about a grilled cheese sandwich done right—it's humble food that somehow never feels that way when the cheese is melted perfectly and the bread has that satisfying crunch. It reminded me that sometimes the most comforting meals are the ones that don't apologize for being simple.

Why Sun-Dried Tomato Pesto Makes All the Difference

Regular butter and cheese would be fine, but the pesto transforms this from standard comfort food into something with real personality. The concentrated tomato flavor, garlic, and herbs give you that Italian-inspired depth that makes people pause mid-bite and ask what you did differently.

Bread Choice Actually Matters Here

Sourdough creates a slightly chewy center with a crispy exterior that stands up to the richness of the cheese and pesto without getting overshadowed. Whole wheat adds a subtle nuttiness that feels more substantial, while classic white bread keeps things approachable and lets the pesto shine brightest.

Making This Your Own

The sandwich is perfect as-is, but it also welcomes personalization without losing its identity. Fresh basil leaves add a peppery brightness, Parmesan brings umami depth, and swapping mozzarella for provolone or fontina creates completely different textural and flavor experiences—all of them delicious.

• Add a thin slice of ripe tomato under the cheese if you want extra moisture and acidity.
• Try fresh basil leaves layered with the mozzarella for herbal complexity that feels less heavy than the pesto alone.
• Keep the heat at medium so you get golden bread and fully melted cheese instead of racing between the two.

This sandwich proves that remarkable food doesn't require complicated techniques or a long ingredients list—just butter, heat, and knowing what flavors want to be together. Serve it with tomato soup, a bright salad, or honestly just by itself.
