Filipino Beef Steak

Step 1
Place sliced beef in a large bowl. Whisk together lemon juice, soy sauce, sugar, salt, and pepper in a small bowl; pour over beef and toss to coat. Stir in cornstarch. Cover and refrigerate for 1 hour to overnight.

Step 2
Heat vegetable oil in a large skillet over medium heat.

Step 3
Remove beef slices from marinade, shaking to remove any excess liquid. Discard marinade.

Step 4
Working in batches, fry beef slices in hot oil until they start to firm and are reddish-pink and juicy in the center, 2 to 4 minutes per side. Transfer beef slices to a serving platter.

Step 5
Heat olive oil in a small skillet over medium heat. Cook and stir onion and garlic in hot oil until onion is golden brown, 5 to 7 minutes; spoon over beef slices.
