Ingredients You’ll Need
For the Stir Fry:
- 1 lb flank steak or sirloin, thinly sliced
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- 1 yellow bell pepper, sliced
- 1 small onion, sliced
- 1 tbsp sesame oil or olive oil
- Cooked rice or cauliflower rice (for serving)
For the Sauce:
- 3 tbsp soy sauce (or low-sodium)
- 2 tbsp oyster sauce
- 1 tbsp cornstarch
- 1 tbsp brown sugar or honey
- 1 tsp fresh garlic, minced
- 1 tsp fresh ginger, minced
- 2–3 tbsp water

Step-by-Step Cooking Instructions
🔹 Step 1: Prep the Meat and Veggies
Slice your steak into thin strips against the grain. Wash and cut the bell peppers and onion. Set everything aside in separate bowls.
🔹 Step 2: Make the Sauce
In a small bowl, whisk together soy sauce, oyster sauce, brown sugar, cornstarch, water, garlic, and ginger. Stir until smooth.
🔹 Step 3: Sear the Beef
Heat sesame oil in a large skillet or wok over high heat. Add beef strips in batches to avoid overcrowding. Sear for 1–2 minutes per side until browned, then remove from pan.
🔹 Step 4: Cook the Vegetables
In the same pan, add a little more oil if needed. Sauté onions and bell peppers for 3–4 minutes until just tender but still crisp.
🔹 Step 5: Combine Everything
Return the beef to the pan. Pour in the sauce and toss everything to coat. Stir-fry for 2–3 more minutes until the sauce thickens and everything is heated through.

🔹 What rice is best for meal prep?
Jasmine rice, brown rice, or even cauliflower rice works great and reheats well.

Yes! Add red pepper flakes, chili garlic sauce, or sriracha to the sauce for extra heat. Adjust to your spice level preference.

Flank steak, sirloin, or skirt steak are great options. They’re tender when sliced thin against the grain and cook quickly.

Use low-sodium soy sauce and omit or reduce the oyster sauce. You can also add a splash of rice vinegar or lemon juice to brighten the flavor.

Broccoli, snap peas, mushrooms, or baby corn make excellent additions. Just adjust the cooking time so all veggies remain crisp-tender.

Let the stir fry cool completely before sealing in containers. Store sauce separately if you prefer a crisp texture when reheating.
