30-Min. Easy Beef Tomato Stir-Fry
Tender beef and juicy tomatoes are stir-fried in a sweet and savory sauce. This easy beef tomato stir-fry recipe is ready in just 30 minutes. The velveted beef stays tender and juicy while the tomatoes create a rich, flavorful sauce.
Ingredients
- 0.5 lb flank steak (sirloin, tri-tip, or hanger steak also works)
- 4 medium roma tomatoes each cut lengthwise into 4 wedges
- 1 small onion diced
- 2 green onions finely chopped
- ½ tablespoon ginger thinly sliced
- 1 garlic clove minced
- ¼ cup ketchup
- 1 tablespoon white granulated sugar
- 1 tablespoon vegetable oil or any neutral oil
Beef Marinade:
- 2 teaspoon regular soy sauce or light soy sauce
- 1 tsp Shaoxing Cooking Wine or dry sherry
- 1.5 teaspoon cornstarch
- ¼ teaspoon baking soda
- ¼ teaspoon garlic powder
- 2 teaspoon water cold
Cornstarch Slurry:
- 1 tablespoon cornstarch
- 1 cup water cold
Instructions
- If time permits, freeze the flank steak for 45 minutes to firm it up for easier slicing. Slice the beef against the grain at a 45-degree angle into ¼-inch thick pieces.
- Place the sliced beef in a large mixing bowl. Add all the marinade ingredients and mix well until the liquids are fully absorbed. Marinate at room temperature for 15 minutes.
- Whisk the cornstarch and cold water together in a small bowl until smooth. Set aside.
- Heat the vegetable oil in a large pan or wok over medium heat. Add the marinated beef and quickly spread the slices apart into a single layer. Cook, stirring occasionally, until browned on the outside and slightly pink inside.
- Add the garlic, onion, ginger, and ketchup. Stir-fry for 1 minute until fragrant and the onion is slightly softened.
- Whisk the cornstarch slurry again, then pour it into the pan and add the tomatoes. Gently stir and simmer uncovered for 2-3 minutes until the tomatoes slightly soften and the sauce reduces and thickens.
- Gently fold in the sugar without breaking up the tomatoes. Remove from the heat and garnish with green onion. Serve immediately.
