Baked Potato With Mozzarella Cheese Recipe: Melted String Cheese Rivers and Crispy Top Magic

This baked potato with mozzarella cheese recipe transforms a simple side into a restaurant-worthy centerpiece with crispy golden skin and rivers of melted string cheese. The secret lies in baking the potato until tender, then crowning it with mozzarella that stretches into gooey, golden strands when broiled.

I developed this technique after years of perfecting the balance between fluffy potato and perfectly melted cheese—no soggy tops or undercooked centers here.

The beauty of this dish is its simplicity: just a few ingredients and 15 minutes of active time, but the result feels indulgent. You'll start with a russet potato baked until fork-tender, then top it with slices of string cheese that melt into luxurious rivers when exposed to the broiler.

The contrast between the crispy skin and creamy cheese creates every bite's perfect texture.

What makes this recipe special is how it elevates a basic potato into something worthy of a special occasion. The mozzarella melts into stretchy, golden strands that cling perfectly to the fluffy potato, while the crispy skin adds satisfying texture.

This dish works as a hearty side or even a main course when paired with simple greens or a fresh salad.

For extra flavor, consider adding a pat of garlic butter, a sprinkle of chives, or a drizzle of olive oil before broiling. The key is patience—let the cheese melt slowly to achieve those perfect, glossy rivers. Once you try this version, you'll never settle for plain baked potatoes again.

Ingredients for baked potato with mozzarella cheese

Four russets and eight ounces of string cheese—simple ingredients for a showstopping dish.

Russets are non-negotiable here—their waxy texture holds up to baking without turning mealy. Local farms or grocery store organic sections often have the freshest potatoes, but any russet will work. Look for firm skin and no sprouts. The string cheese? Low-moisture is key—it melts into perfect rivers instead of a greasy puddle. I grab mine from the deli counter at Whole Foods, but any grocery store brand works. Slice it into thin strips (about 1/4-inch thick) for even melting. For extra flavor, add a pinch of smoked paprika to the cheese before broiling.

No string cheese? Fresh mozzarella sliced thinly works in a pinch, though it won’t stretch as dramatically. Short on chives? Green onions or parsley add a similar freshness. The olive oil can be swapped for melted butter if you prefer—just brush it on right before broiling for extra richness. Garlic powder is a must for flavor, but fresh minced garlic (1/2 tsp) takes it to another level. For a smoky twist, add a dash of smoked salt with the black pepper.

Potatoes keep best in a cool, dark place for 2-3 weeks. Once baked, store leftovers wrapped in foil in the fridge for up to 3 days. Reheat in the oven at 375°F (190°C) for 10-15 minutes to restore crispiness. For meal prep, bake a batch of potatoes ahead and freeze them untopped—they’ll reheat perfectly when you’re ready to add the cheese. The broiled cheese topping is best served immediately, but you can reheat it under the broiler for 2-3 minutes if needed.

Step-by-step instructions for baked potato with string cheese

Here's the method for achieving that perfect crispy skin and gooey cheese rivers.

Preheat your oven to 425°F for maximum crispiness. Scrub the 4 whole Russet Potatoes thoroughly under cold water to remove any dirt, but leave them unpeeled—the skin adds texture and flavor. Pierce each potato all over with a fork, about 8-10 times per potato. This creates steam vents that prevent explosions in the oven.

Place the potatoes on a baking sheet and drizzle with 1 tablespoon Olive Oil. Toss gently to coat evenly, then sprinkle with 1.5 teaspoons Kosher Salt, 0.5 teaspoon Black Pepper, and 1 teaspoon Garlic Powder. The oil helps create that coveted crispy skin, while the seasoning penetrates the skin during baking. Rotate the sheet halfway through baking for even browning.

Bake the potatoes for 45-55 minutes, flipping them halfway through, until they feel soft when squeezed gently and a fork slides in easily. The exact time depends on your oven—smaller potatoes will cook faster than larger ones. You're aiming for a crispy exterior that gives way to fluffy interior when pierced.

Here's the thing—don't overbake. Potatoes continue cooking after you remove them from the oven. You want them tender but still holding their shape when sliced. If you're unsure, check at the 45-minute mark. Once they're done, transfer them to a wire rack to let steam escape—this prevents soggy skin when you add the cheese.

While the potatoes are still hot, use a serrated knife to cut a deep cross in the top of each potato, creating four equal sections that meet in the center. Be careful not to cut all the way through. The heat from the potatoes will help melt the cheese into perfect rivers when you add it.

Melt 0.5 cup Unsalted Butter in a small saucepan over low heat until completely liquid. Use a pastry brush to generously coat the insides of each potato section with the melted butter. This step is crucial—it creates a barrier that prevents the cheese from sticking to the potato and ensures those beautiful rivers you're after.

Arrange the potatoes on a baking sheet lined with aluminum foil. Place 2 slices of String Cheese (about 2 ounces) into each cross cut, letting them rest against the sides. The string cheese's low moisture content means it melts perfectly without creating a watery sauce.

Broil the potatoes on high for 2-3 minutes, watching closely. You want the cheese to melt into golden rivers that flow down the sides, not burn. If the cheese starts to brown too quickly, move the sheet back slightly from the broiler. The cheese should be fully melted and bubbly, creating that signature restaurant-style presentation.

Remove the potatoes from the oven and immediately sprinkle with 2 tablespoons chopped Fresh Chives. The chives add a fresh, bright contrast to the rich, melted cheese. Serve while the potatoes are piping hot—this is when the cheese is at its most spectacular, flowing and stretchy.

Each bite should deliver crispy skin, fluffy potato, and gooey cheese rivers. The butter-brushed insides prevent the cheese from sticking, while the chives add a pop of color and freshness. This technique transforms a simple baked potato into an impressive, restaurant-quality dish that's surprisingly easy to make at home.

This version is all about that iconic diner experience you crave after a late-night drive. Start with russet potatoes baked to perfection, then top with string cheese that melts into golden rivers when broiled.

For an Italian twist, swap the garlic powder for fresh basil and red pepper flakes. Use fresh mozzarella instead of string cheese, sliced into thin strips. After broiling, drizzle with high-quality olive oil and sprinkle with fresh basil leaves and a pinch of flaky sea salt.

The acidity from the basil cuts through the richness beautifully.

Southwest Spiced Fiesta

Give your baked potatoes a smoky kick by mixing ½ tsp smoked paprika and ¼ tsp cumin into the butter you brush on the insides. Use smoked gouda instead of mozzarella for a deeper flavor, and top with diced jalapeños and chopped cilantro after broiling.

The smoky cheese pairs perfectly with the spicy kick. 🌶️

Turn this into a fun, interactive dish by setting up a toppings bar. Bake the potatoes as directed, then offer guests options like crumbled bacon, sour cream, green onions, hot sauce, and extra cheese.

I love using cheddar cheese alongside the mozzarella for a sharper flavor. Perfect for game day or family gatherings!
