This savory Chinese pepper steak is a quick stir-fry that turns simple beef and vegetables into a flavorful and satisfying dinner. Tender strips of marinated beef are seared until caramelized, then tossed with crisp onions, bell peppers, and juicy tomatoes in a glossy sauce that clings to every bite. Perfect with steamed rice or noodles, it delivers that bold takeout taste with the comfort of home cooking.
I first made this dish to recreate a favorite from my childhood Sunday dinners. After experimenting with the marinade a few times this version brought back those nostalgic flavors my family loves.

- Marinate the Beef:
- Coat the beef strips evenly in the marinade Let rest for at least 15 minutes or up to 2 hours in the fridge This step tenderizes and infuses flavor
- Sear the Beef:
- Heat a wok or skillet with a spoonful of oil until shimmering Cook beef in small batches for about 3 minutes until edges caramelize but the inside stays slightly pink Set aside
- Add Vegetables:
- Return the wok to high heat with a bit more oil Stir fry onions for 2 minutes until softened but still crisp The smoky char adds depth
- Incorporate the Bell Pepper:
- Add the bell pepper and stir fry 2 minutes more to keep them crunchy and bright
- Blend in the Tomatoes:
- Add tomato wedges and return the beef with juices Toss gently for 1 to 2 minutes just until tomatoes release some juice but still hold shape The sauce comes together naturally
- Serve and Relish:
- Transfer to a serving plate Garnish with green onions if desired Serve hot with steamed rice or noodles

My favorite part is when the glossy sauce thickens and coats every bite The first time I achieved that restaurant style finish my husband thought we had ordered takeout Now it is a regular Friday night tradition.
