Instructions

1. Step 1: In a bowl, combine 1 lb thinly sliced beef sirloin, 1/4 cup calamansi juice, 1/4 cup soy sauce, 4 minced garlic cloves, and 1/2 tsp black pepper. Marinate for at least 30 minutes in the refrigerator for deep flavor.
2. Step 2: Heat 2 tbsp vegetable oil in a large skillet over medium heat. Add 2 sliced large yellow onions and 1 tsp brown sugar. Sauté for 10 minutes, stirring frequently until onions are soft and caramelized with a golden brown color.
3. Step 3: Remove caramelized onions and set aside. Add remaining 1 tbsp vegetable oil to the skillet, increase heat to medium-high, and remove beef from marinade (reserve marinade). Sear beef slices in batches for 2-3 minutes per side until browned but still tender.
4. Step 4: Pour reserved marinade and 1/4 cup water into the pan with the beef. Simmer for 5 minutes until the sauce reduces slightly and coats the beef.
5. Step 5: Return the caramelized onions to the skillet and stir gently to combine. Cook together for another 1-2 minutes until heated through. Serve hot with steamed rice.
