Save on Pinterest There's something about the smell of butter hitting a hot skillet that makes me want to throw together a sandwich. One lazy afternoon, I was staring at a vine-ripened tomato on my counter, some basil my neighbor had given me, and the urge to make something warm and cheesy. What emerged was this tomato basil grilled cheese—simple enough that I've made it a dozen times since, yet somehow different every time depending on the bread or how I position the tomato slices.
I made these for a friend who showed up unannounced on a rainy Tuesday, and I watched her close her eyes on the first bite—the melted cheese meeting the acidity of the tomato, with basil cutting through it all. That moment convinced me this isn't just a sandwich, it's proof that the best meals don't need to be complicated.
Ingredients
- Sourdough or country-style bread: Use whatever has character and structure; thin sandwich bread turns to mush, but a rustic loaf holds everything together and gets those gorgeous golden edges.
- Mozzarella cheese: Fresh or low-moisture both work, though low-moisture melts more predictably; slicing it yourself feels fussier but helps you control the coverage.
- Unsalted butter, softened: This is the difference between burnt spots and even browning—soft butter spreads without tearing the bread.
- Ripe tomato: A tomato that actually tastes like something changes everything; out-of-season ones can turn watery and disappointing.
- Fresh basil leaves: Tear them by hand rather than cutting—a knife bruises the leaves and they lose that bright, peppery bite.
- Salt and pepper: Don't skip seasoning the tomato itself; it wakes up the whole sandwich.
Instructions
- Butter your bread generously:
- Spread softened butter over one side of each slice until it's evenly coated—skimping here means dry, pale bread. Think of it as creating a protective, golden layer rather than just coating.
- Build the sandwich:
- Place two bread slices buttered side down on your cutting board. Layer half the mozzarella on each, then arrange tomato slices in a single layer (I usually use four or five per sandwich), scatter basil leaves over the tomato, and finish with a small pinch of salt and fresh pepper. Top with the remaining bread, buttered side up, and press gently to help everything stay together.
- Heat your skillet:
- Use medium heat with a large skillet or griddle—high heat burns the outside before the cheese melts. Give it a minute to warm through so you're cooking on a hot but not aggressive surface.
- Cook until golden:
- Place the sandwiches in the skillet and let them sit for 3 to 4 minutes without moving them; you want that butter to turn golden and crispy, and the cheese to actually soften. A gentle press with your spatula helps, but you're not smashing—just encouraging contact with the heat.
- Flip and finish:
- Flip carefully using your spatula, watching as the cooked side reveals itself all golden and toasted. Cook the other side another 3 to 4 minutes until it matches the first side and the cheese feels soft and almost melting inside.
- Rest and serve:
- Let the sandwich sit on your plate for one minute—this lets the cheese set just slightly so it doesn't ooze everywhere when you bite in. Slice diagonally because it somehow tastes better that way, and serve while it's still warm.
Save on Pinterest My mom called me while I was eating one of these, and I found myself trying to describe the moment when the warm bread gives way to the soft cheese and the tomato releases just a little juice—I gave up and told her to make one herself. Food rarely sparks a conversation quite like it does when you're actually experiencing it together.
Variations to Explore
Once you nail the basic method, this sandwich becomes a canvas. I've tried provolone for a sharper edge, or sometimes a thin slice of prosciutto tucked in with the tomato if I'm feeling fancy and it's the kind of day where that matters. Cheddar brings earthiness, and arugula or spinach adds a peppery crunch that plays beautifully against the sweetness of the tomato.
Timing and Prep Work
The 20-minute timeline includes everything, but most of it is hands-on cooking—actual prep is just slicing tomato and pulling basil leaves, maybe five minutes if you're being slow about it. I like to have all my ingredients ready before I touch the butter, so once that skillet heats up, I'm building and cooking without interruption.
Making It Better Every Time
I've learned that the small details change the sandwich entirely. The softness of your butter, how thin you slice the tomato, whether you let that pan get truly hot before adding the sandwich—these aren't things you'll perfect the first time, but they're easy to adjust the next time. That's what makes this sandwich so good to revisit.
- A balsamic glaze drizzled on after cooking adds a sophisticated tang that lingers.
- If your tomato is watery, gently pat the slices dry with a paper towel before building the sandwich.
- Medium heat is your friend—patience beats speed every single time here.
