Save Pin Rainy Tuesday afternoons were made for grilled cheese experiments in my tiny apartment kitchen. I'd been stuck in a rut with basic singles on white bread until my neighbor Sarah brought over her sourdough starter and changed everything. This triple cheese version came together by accident when I was trying to clear out my cheese drawer before grocery day. The way mozzarella creates those ridiculous cheese pulls while cheddar brings the sharp punch and provolone adds the mellow finish it became my go to comfort food immediately.
My roommate walked in during my first attempt and asked if I was running a restaurant. The smell was filling our entire apartment and she stood there watching the pan like a hawk until I offered to make her one too. Now whenever either of us has a terrible day at work we text each other simply sourdough and cheese and meet in the kitchen without another word needed.
Ingredients
- Thick cut sourdough bread: The sturdy texture holds up to the cheese weight and develops incredible crunch while thinner slices would turn soggy or burn before the cheese melts
- Sharp cheddar slices: This brings the bold punch that cuts through the richness and I've learned through many failed attempts that mild cheddar just disappears into the sandwich
- Provolone slices: The mellow creamy element that bridges the gap between sharp and milky flavors plus it melts beautifully without separating
- Shredded mozzarella: This is what creates those Instagram worthy cheese pulls and fills every nook between the other cheese layers for maximum goo factor
- Unsalted butter: Softened to room temperature spreads evenly without tearing the bread and I prefer controlling my own salt levels with the cheese selection
- Mayonnaise: Optional but honestly it makes the exterior ridiculously crispy and golden brown in ways butter alone never quite achieves
Instructions
- Prep your bread canvas:
- Lay out all four sourdough slices and spread softened butter generously on one side of each piece making sure to cover every inch to the edges for even browning
- Build the cheese towers:
- Place two slices buttered side down then layer on cheddar first followed by provolone then finish with a generous pile of shredded mozzarella to seal everything together
- Close the deal:
- Top each sandwich with the remaining bread slices buttered side up and press down gently with your palms to help everything adhere before it hits the heat
- Get your pan ready:
- Heat a large skillet over medium low heat which I've learned is crucial because high heat burns the bread before the cheese has time to melt properly
- The patient flip:
- Cook for 3 to 5 minutes per side pressing occasionally with your spatula until deep golden brown and use a wide spatula to flip carefully so no cheese escapes
- The resting moment:
- Let the sandwiches sit on a cutting board for exactly one minute before slicing which allows the cheese to set just enough that it doesn't immediately ooze out when you cut
Save Pin Last winter my sister came over during a snowstorm and we made these while watching old movies. She took one bite went completely silent and asked why I'd been holding out on her. Now she texts me photos of her own attempts though she still hasn't mastered the patience element and always rushes the heat setting.
Getting The Perfect Melt
The secret is layering your cheese strategically with shredded cheese between slices because it melts faster and more evenly. I also learned to grate my own cheese instead of buying pre shredded bags since the anti caking coating on store bought cheese prevents it from melting into that cohesive cheese pull we're all chasing.
Bread Selection Matters
Not all sourdough is created equal and I've discovered that the slightly stale day old loaf actually grills better than fresh bread. The reduced moisture content means your exterior gets crisper while the inside stays soft instead of becoming doughy or steam soaked from the melting cheese.
Serving Ideas
Classic tomato soup is the obvious pairing but I've also served these alongside a sharp arugula salad to cut through the richness. Sometimes I'll add thinly sliced apples or pears inside the sandwich for sweet contrast especially when I'm feeling fancy.
- Try spreading a thin layer of Dijon mustard inside for extra zip
- A splash of hot honey over the finished sandwich creates sweet heat
- Leftovers reheat surprisingly well in a toaster oven at 350 degrees

Recipe FAQs
- → How do I prevent the bread from burning while melting the cheese?
Cook on medium-low heat rather than high temperature. This allows the cheese to melt gradually while the butter creates an even, golden-brown crust without burning. Pressing gently on the sandwich helps with even cooking and cheese distribution.
- → Can I use different cheeses?
Absolutely. Swiss, Gruyère, or fontina work wonderfully. Mix and match based on your preferences. Just ensure you use cheeses that melt well for the best texture and flavor combination.
- → Why add mayonnaise to the bread?
Mayonnaise enhances the crispiness of the bread exterior, creating a more textured crust similar to using extra butter. It's optional but recommended for maximum crunch and flavor depth.
- → What's the best way to avoid cheese leaking out?
Layer the cheeses evenly so they melt uniformly without pooling. Flip carefully using a spatula for support, and press gently during cooking rather than aggressively. Letting the sandwich rest briefly after cooking helps set the melted cheese.
- → Can I make this gluten-free?
Yes, simply use gluten-free sourdough bread. The cooking method remains the same. Ensure all other ingredients like butter and mayonnaise are certified gluten-free if you have severe sensitivities.
- → What sides pair well with this sandwich?
Tomato soup is the classic pairing, while a crisp green salad provides a refreshing contrast. Pickled vegetables or french fries also complement the rich, melty sandwich perfectly.
