Beef Tomato – Hawaii’s Chinese-Style Stir-Fry Classic

Beef tomato is one of those dishes that every local kid in Hawaii grew up eating. It’s simple—tender slices of beef stir-fried with juicy tomato wedges in a savory-sweet sauce—but that simplicity is exactly what makes it so good. Quick enough for a weeknight dinner, satisfying enough to make everyone ask for seconds, and perfect over a big bowl of hot rice.

This dish has roots in Chinese cuisine, brought to Hawaii by immigrants who worked the sugar plantations. Like so many Hawaiian dishes, it evolved to use local ingredients and suit local tastes. The result is a stir-fry that’s uniquely Hawaiian—Chinese technique meets island sensibility.

What Is Beef Tomato?

Beef tomato (also called “tomato beef” at some restaurants) is a Cantonese-style stir-fry that’s become a staple of Hawaiian-Chinese cuisine. The key elements are:

• Thinly sliced beef – Usually flank steak or sirloin
• Fresh tomato wedges – Added at the end to keep them slightly firm
• Savory-sweet sauce – Soy sauce, oyster sauce, and a touch of sugar
• Quick cooking – High heat, fast stir-fry technique

The Hawaiian-Chinese Connection

Chinese immigrants were among the first groups to arrive in Hawaii for plantation work, beginning in the 1850s. They brought their culinary traditions, including the stir-fry technique that would revolutionize local cooking. Beef tomato became a favorite because it was quick, economical, and delicious—exactly what working families needed.

Today, you’ll find beef tomato at Chinese restaurants, plate lunch spots, and home kitchens across Hawaii. It’s a perfect example of how immigrant cuisine became local cuisine — right alongside other wok favorites like Teriyaki Chicken.

Ingredients

For the Beef:

• 1 lb flank steak or sirloin, thinly sliced against the grain
• 1 tablespoon soy sauce
• 1 tablespoon cornstarch
• 1 teaspoon sesame oil

For the Sauce:

• 2 tablespoons oyster sauce
• 1 tablespoon soy sauce
• 1 tablespoon sugar
• ½ cup water or beef broth
• 1 tablespoon cornstarch mixed with 2 tablespoons water

For Stir-Frying:

• 3 tablespoons vegetable oil, divided
• 3 cloves garlic, minced
• 1 inch fresh ginger, sliced
• 3 medium tomatoes, cut into wedges
• 1 small onion, sliced (optional)
• 2 green onions, cut into 2-inch pieces
• Hot white rice for serving

Instructions

1. Marinate the beef: Toss sliced beef with soy sauce, cornstarch, and sesame oil. Let sit for 15-20 minutes while you prep other ingredients.
2. Mix the sauce: In a small bowl, combine oyster sauce, soy sauce, sugar, and water. Set aside. Have the cornstarch slurry ready separately.
3. Stir-fry the beef: Heat 2 tablespoons oil in a wok or large skillet over high heat until smoking. Add beef in a single layer and let it sear for 30 seconds without stirring. Then stir-fry for another minute until just cooked. Remove to a plate.
4. Cook aromatics: Add remaining 1 tablespoon oil to the wok. Add garlic and ginger, stir-fry for 30 seconds until fragrant.

5. Add tomatoes: Add tomato wedges and onion (if using). Stir-fry for 1-2 minutes—you want the tomatoes slightly softened but still holding their shape.
6. Combine and sauce: Return beef to the wok. Pour in the sauce mixture and toss everything together. Add the cornstarch slurry and stir until the sauce thickens and coats everything, about 30 seconds.
7. Finish and serve: Toss in green onions. Give it one final stir and immediately transfer to a serving plate. Serve hot over white rice.

Tips for Perfect Beef Tomato

• Slice beef thinly – Partially freeze the steak for 20 minutes to make slicing easier
• High heat is essential – A smoking hot wok gives you that restaurant-quality sear. If you’re looking to upgrade your setup, check out our guide to choosing the right wok
• Don’t overcook the tomatoes – They should be warmed through but not mushy
• Work quickly – Once you start stir-frying, the whole dish comes together in minutes

Variations

• Add vegetables – Bell peppers or snap peas work great
• Chicken tomato – Substitute sliced chicken breast or thigh
• Extra saucy – Double the sauce for more gravy over rice
• Spicy version – Add sliced Hawaiian chili peppers or red pepper flakes

Serving Suggestions

Beef tomato is best served:

• Over hot white rice – The only way, really
• As part of a Chinese meal – Alongside other stir-fries and steamed fish
• Family style – Big platter in the center of the table
