Beef Bulgogi Udon with Melted Mozzarella

This beef bulgogi udon brings together sweet, smoky Korean BBQ flavors with chewy udon noodles and a blanket of melted mozzarella. It's a weeknight dinner that feels indulgent but comes together in just 15 minutes.

The marinade, made with soy, grated pear, and sesame, tenderizes the beef and builds a glossy, caramelized coating. Toss in thick udon noodles, let the cheese melt over everything, and you have a sizzling, stretchy, satisfying bowl that's sure to become a regular in your rotation.

Start by marinating thinly sliced ribeye in a quick mixture of soy sauce, grated Asian pear, sesame oil, garlic, and brown sugar. The pear not only adds sweetness but also helps tenderize the beef.

Sear the beef in a smoking-hot wok, then add udon noodles and scallions, and finish with a generous handful of mozzarella that melts into gooey strands. The result is a savory-sweet, smoky, and utterly comforting noodle dish that's ready in minutes.

Ingredients

Why this recipe works

The key to this dish is the high-heat sear. Cooking the marinated beef in a screaming-hot wok creates a caramelized crust while keeping the interior juicy.

The sugar in the marinade promotes browning and adds a deep, smoky flavor that mimics the essence of Korean BBQ. The wok's wide surface area ensures the beef gets direct contact with the heat, not steaming in its own juices.

The combination of chewy udon and stretchy mozzarella provides textural contrast. Udon's thick, bouncy noodles soak up the savory sauce without turning mushy, while the mozzarella adds a mild, creamy richness that balances the salty soy and sweet pear. The cheese also creates a visually appealing pull that makes the dish feel special.

Notes and substitutions

Use high-quality, thinly sliced ribeye for the best texture. If you can't find pre-sliced, freeze the steak for 15-20 minutes to make slicing easier.

The Asian pear is essential for its enzymes that tenderize the meat; if unavailable, a Bosc pear or apple works as a substitute. Fresh udon noodles are ideal, but vacuum-packed or frozen ones work well—just rinse them to separate.

Shredded mozzarella melts quickly and evenly; avoid fresh mozzarella balls as they release too much water. For a spicier kick, add a pinch of gochugaru (Korean chili flakes) to the marinade. This recipe is best served immediately, as the cheese will set as it cools.

• Asian pear: Use a ripe Bosc pear or a crisp apple, grated, for similar sweetness and tenderizing effect.
• Ribeye beef: Thinly sliced sirloin or flank steak works well; just slice against the grain.
• Udon noodles: Thick wheat noodles like lo mein or spaghetti can substitute, though texture will vary.
