Save The smell of balsamic reducing on the stove always pulls me into the kitchen, curious and hungry. I stumbled onto this combination during a lazy Sunday afternoon when I wanted something more exciting than my usual grilled cheese. The first bite—crispy bread giving way to that tangy sweetness against creamy mozzarella—made me wonder why I'd never thought of it before. Now it's my go-to when I need comfort food that feels a little fancy without the fuss.
I’ve been getting a lot of questions about the pot I use for cozy one-pot meals and small-batch recipes, so I wanted to quickly share it here.
This is the Martha Stewart heart-shaped enameled cast iron Dutch oven (2-quart). It’s one of those pieces I reach for constantly when testing soups, stews, baked casseroles, and smaller comfort-food recipes.
- Heats evenly with no hot spots (huge for slow cooking)
- Non-reactive enamel interior — no seasoning required
- Perfect size for small households or side dishes
- Sturdy handles, easy to move from oven to table

I made these for my sister last winter when she was visiting, and she actually paused mid-bite to ask what kind of magic was happening. We ended up sitting at the counter, eating them straight from the cutting board while catching up about everything and nothing. Sometimes the best meals aren't the ones that take hours to prepare—they're the ones that bring people together effortlessly.
Ingredients
- Sourdough or rustic bread: The sturdier texture holds up beautifully to the juicy tomatoes and melting cheese without getting soggy
- Unsalted butter: Softening it first means you can spread it evenly—cold butter tears the bread and leaves bare patches
- Fresh mozzarella: I've tried shredded mozzarella, but the fresh slices melt into these incredible creamy pockets that taste completely different
- Ripe tomatoes: Choose ones that yield slightly when you press them—meaty but still juicy
- Fresh basil: Dried basil won't work here, you need that bright, peppery punch that only fresh leaves provide
- Balsamic glaze: If you can't find it at the store, simmer regular balsamic vinegar until it coats the back of a spoon
- Parmesan cheese: Totally optional, but that salty umami kick makes everything taste more rounded
Instructions
- Butter your bread:
- Spread the softened butter generously on one side of each slice, all the way to the edges—those crispy golden edges are half the pleasure
- Build the base:
- Place two slices butter-side down and start layering mozzarella first so it melts into the bread
- Add the fresh elements:
- Lay tomato slices over the cheese, then tuck basil leaves between them so they don't slide off
- The secret ingredient:
- Drizzle that balsamic glaze right over the tomatoes—trust me, it soaks into everything while cooking
- Finish assembling:
- Sprinkle with salt, pepper, and Parmesan if you're using it, then top with remaining slices butter-side up
- Grill to perfection:
- Cook in a heated nonstick skillet about 4 minutes per side, pressing gently so the bread makes even contact with the pan
- The waiting game:
- Let them rest for one minute before slicing—this keeps all that molten cheese from spilling out immediately
Save This sandwich became my daughter's request after every soccer practice during her senior year. There was something about pulling those gooey, balsamic-drizzled halves apart that made even the toughest days feel a little more manageable. Food memories aren't always about fancy dinners—sometimes they're about repeat performances requested by hungry teenagers.
Choosing the Right Bread
After testing everything from basic white bread to multigrain, I've learned that sourdough's tang actually complements the balsamic instead of competing with it. Look for a loaf with some structure and a decent crumb—anything too soft will collapse under all those layers. Rustic Italian bread works beautifully too, just slice it slightly thicker so it can handle the weight.
Make-Ahead Magic
I've prepped everything the night before and assembled them right before cooking with great success. Just keep the tomato slices separate on paper towels so they don't make the bread soggy, and have the balsamic glaze ready in a small bowl. The whole process moves so fast that even hungry weeknight crowds won't mind the brief wait.
Serving Suggestions
A simple arugula salad with lemon vinaigrette cuts through the richness beautifully, but honestly, I've eaten these solo more times than I'll admit. They're substantial enough to feel like a full meal, especially paired with something crisp and cold to drink. Sometimes I'll add a bowl of tomato soup on the side when I want full comfort-food mode.
- Try swapping the basil for fresh arugula if you want something peppier
- A thin layer of pesto underneath the cheese adds another dimension of basil flavor
- These reheat surprisingly well in a 350°F oven for about 10 minutes if you have leftovers
Save Some recipes become staples because they're simple, and others because they're simply delicious. This one happens to be both.
