For the Marinade/Sauce:
- 3 tbsp soy sauce
- 1 tbsp oyster sauce
- 1 tbsp hoisin sauce
- 1 tsp sesame oil
- 1 tsp brown sugar or honey
- 1 tsp cornstarch
- 2 tbsp water
- Red pepper flakes (optional, for heat)

- Measuring spoons and cups
- Tongs or spatula
- Grater (for the ginger)
Step-by-Step Instructions
1. Marinate the Beef
Start by mixing the soy sauce, oyster sauce, hoisin, sesame oil, brown sugar or honey, cornstarch, and water in a bowl. Toss in the sliced beef, making sure it’s well coated. Let it marinate for 15 to 30 minutes—the longer, the better for flavor.
Pro Tip: You can prep the beef in the morning and refrigerate it until dinner for deeper flavor.
2. Stir-Fry the Beef
Heat 1 tbsp oil in a hot skillet or wok over medium-high heat. Sear the beef in batches (don’t overcrowd the pan!) until nicely browned and slightly caramelized. Set it aside on a plate.
Shortcut Tip: If you’re really short on time, use pre-sliced stir-fry beef from the grocery store.
3. Cook the Veggies
In the same pan, add the remaining 1 tbsp oil. Add the garlic and ginger, stirring for about 30 seconds until fragrant. Then toss in the bell peppers. Stir-fry for 2–3 minutes, just until the peppers begin to soften but still retain a bit of crunch.
4. Bring It All Together
Return the beef to the pan, along with any remaining marinade. Toss everything together and stir-fry for another 1–2 minutes until everything is coated and heated through. Garnish with sliced green onions if using.
How to Serve It
This stir-fry pairs beautifully with:
- Steamed jasmine or brown rice
- Noodles (soba, udon, or even rice noodles)
- A drizzle of chili oil for an extra kick
- Toasted sesame seeds for crunch
Drink Pairing Ideas:
- A crisp, cold lager or a light-bodied red wine like Pinot Noir
- Iced green tea with lemon
- Sparkling water with lime
Storing & Reheating Leftovers
Refrigerator: Store any leftovers in an airtight container in the fridge for up to 3 days.
Reheating: Reheat in a pan over medium heat with a splash of water or soy sauce to loosen up the sauce, or microwave for 1–2 minutes until hot.
Freezer-Friendly? While technically possible, the bell peppers can become mushy after thawing. For best results, enjoy fresh or refrigerate only.
Variations & Substitutions
- Protein Swap: Try chicken, shrimp, or tofu instead of beef.
- Vegetable Add-Ins: Snow peas, broccoli florets, mushrooms, or thinly sliced carrots are all great additions.
- Low-Carb Option: Serve over cauliflower rice or spiralized zucchini noodles.
- Gluten-Free Version: Use tamari instead of soy sauce and check that your hoisin and oyster sauces are gluten-free.
Frequently Asked Questions
Can I make this ahead of time?
Yes! You can marinate the beef up to 24 hours in advance. You can also chop all your veggies earlier in the day to streamline dinner.
How thin should I slice the beef?
As thin as you can—about ⅛ to ¼ inch thick. Pro tip: pop the beef in the freezer for 15 minutes before slicing for cleaner cuts.
Can I make this vegetarian?
Absolutely! Replace the beef with tofu or a plant-based meat substitute, and swap oyster sauce for mushroom sauce.
What oil is best for stir-frying?
Use a neutral oil with a high smoke point—like canola, vegetable, or peanut oil. Avoid olive oil, which burns more easily.
My sauce is too thick/thin. Help!
If it’s too thick, add a splash of water. Too thin? Mix ½ tsp cornstarch with 1 tbsp cold water and stir it in while cooking.
