Korean Beef Bulgogi with Zucchini Noodles

If you love meals that balance sweet and savory flavors, this Beef Bulgogi with Zucchini Noodles is a delicious recipe to add to your dinner rotation. The beef is sliced very thin, marinated with soy sauce, sesame oil, pear, garlic, mirin, honey, and vinegar, then cooked hot and fast so the edges become beautifully browned while the inside stays tender.

Bulgogi is often served with rice, lettuce wraps, or traditional Korean side dishes, but zucchini noodles make this version lighter and naturally lower in carbs. The zucchini noodles soak up the flavorful juices from the beef, while the fresh garnishes add color, crunch, and brightness.

This dish is quick enough for a weeknight meal once the meat has marinated, but it also feels special enough for entertaining. The key is to slice the beef as thinly as possible and give it enough time to absorb the marinade. Ribeye is a favorite choice because it is tender and well marbled, but sirloin, tenderloin, flank steak, or skirt steak can also work with the right marinating time.

What Is Bulgogi?

Bulgogi, often called Korean beef barbecue, is made with thin slices of marinated beef or pork that are cooked quickly over an open flame, on a grill, or in a hot skillet. The word is commonly understood as “fire meat,” with “bul” meaning fire and “gogi” meaning meat.

The marinade is what makes bulgogi so memorable. It combines salty, sweet, nutty, and aromatic ingredients to create a deeply flavorful sauce that tenderizes the meat and helps it caramelize as it cooks. The result is juicy beef with rich flavor and slightly crisp edges.

In South Korea, bulgogi is a popular dish served in restaurants, at home, and even sold as ready-to-cook marinated meat. This version keeps the classic sweet and savory profile while pairing the beef with zucchini noodles for a fresh and lighter meal.

How Do You Make Beef Bulgogi?

Step 1: Marinate the Beef: Combine the marinade ingredients until well mixed. Place the thinly sliced steak in a heavy-duty ziplock bag, pour in the marinade, and seal the bag tightly. Massage the marinade into the beef so every slice is coated. Let the beef rest for at least 30 minutes; 1 to 2 hours is recommended for the best flavor.

Step 2: Grill or Sear: Cook the steak slices on a preheated barbecue grill or in a hot cast iron pan on the stovetop. Because the slices are very thin, they cook quickly, usually about 20 seconds per side. Cook until the beef is browned and the edges are lightly caramelized.

Step 3: Garnish and Serve: Arrange the zucchini noodles on a plate or in bowls, then top with the hot bulgogi beef. Sprinkle with sesame seeds and chopped green onions just before serving. Serve with kimchi, pickled cucumbers, or your favorite Korean-inspired side dishes.

Recipe Tips

• For easier slicing, place fresh steak in the freezer for 1 to 2 hours until it is firm but still sliceable. This makes it much easier to cut the meat into very thin pieces.
• If using frozen steak, thaw it for 1 to 2 hours at room temperature, or until it is firm enough to slice cleanly with a knife.
• You can also buy pre-sliced beef from an Asian or Korean grocery store. Thinly sliced, unseasoned beef is often sold specifically for bulgogi.
• Do not overcrowd the grill or pan. Cook the meat in batches so it browns quickly instead of steaming.
• Mirin is a Japanese cooking wine that is similar to sake but sweeter and lower in alcohol. If you do not have mirin, Japanese sake or Korean shochu may be used.
