- Beef – Use tender cuts like sirloin, tenderloin, or flank steak; slice thinly against the grain
- Large red and green chilies – Prik chi fa chilies add medium heat; sub with bell peppers for a milder kids version.
- Onion & green onions
- Garlic
- Light soy sauce – Adds saltiness.
- Dark soy sauce – Gives the stir-fry a darker color and a slightly richer, deeper taste.
- Oyster sauce – Adds a savory and slightly sweet flavor.
- White sugar
- White pepper
- Cornstarch – Helps thicken the sauce so it clings to the beef and veggies.
- Water – Adjusts the consistency of the spicy stir-fry sauce so it’s not too thick or dry.
How to make Thai chili beef
Step 1: In a small bowl, stir together the cornstarch and water until smooth. Set aside, this will help thicken the sauce later.

Step 2: Heat oil in a wok or large pan over high heat. Add the thinly sliced beef and sear quickly until just browned. Don’t overcrowd the pan and cook in batches if needed.
Step 3: Lower the heat to medium and toss in the garlic. Stir-fry until it’s golden and fragrant.
Step 4: Pour in the cornstarch mixture, then add the light soy sauce, dark soy sauce, oyster sauce, white sugar, and a pinch of white pepper. Mix well and let everything simmer for a minute so the beef can soak up all that flavor.
Step 5: Add the sliced chilies and onions. Stir-fry for another minute or two, just until the vegetables are cooked to your liking. Toss in the green onions near the end and serve immediately with jasmine rice. Enjoy!

Storage and reheating tips
- Refrigerate: Store leftovers in an airtight container in the fridge for up to 3 days. Let it cool completely before sealing.
- Freeze: Place in a freezer-safe container or bag and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheat: Reheat on the stovetop over medium heat with a splash of water to loosen the sauce. You can also microwave it in short bursts, stirring in between.
