Step 1: Prepare the Marinade
In a ceramic bowl or glass dish, combine soy sauce, brown sugar, garlic, ginger, sesame oil, and a pinch of black pepper.
Whisk until smooth and fully blended.
Step 2: Slice and Marinate the Meat
Thinly slice your ribeye or steak using kitchen shears for ease.
Place the sliced beef into the marinade, along with the onion and green onions.
Thoroughly mix by hand to ensure all ingredients are evenly coated.
Cover with plastic wrap and refrigerate for at least 1 hour, or up to 12 hours for a more intense flavor.
Step 3: Prepare the Bulgogi
Heat a wok, BBQ grill, or large skillet over medium-high heat.
Add a small amount of neutral cooking oil and let it shimmer.
Cook the marinated beef in small batches, laying the slices flat in the pan.
Cook each side for 2-3 minutes until caramelized, or stir continuously for 4-5 minutes.
If desired, drizzle in a little extra marinade for additional flavor, but be cautious to prevent burning.
Remove the cooked beef to a plate and repeat with the remaining portions.
Step 4: Serve Your Bulgogi
Serve the bulgogi over hot cooked rice and garnish with green onions, chives, a drizzle of sesame oil, and a sprinkle of sesame seeds.
You can also serve it in bibimbap or enjoy it wrapped in fresh lettuce leaves.
Step 5: Storing and Meal Prep
Store leftover bulgogi in an airtight container in the fridge for up to 3 days.
Alternatively, freeze it for up to 1 week.
Reheat in small batches for a quick and juicy meal anytime.
