Beef Bell Pepper Stir Fry Recipe
Ingredients
- 1 lb 450 g beef sirloin or flank steak, thinly sliced against the grain
- 1 red bell pepper sliced into thin strips
- 1 yellow bell pepper sliced into thin strips
- 1 medium onion sliced
- 2 cloves garlic minced
- 2 tablespoons vegetable oil or your favorite high-heat oil
- 1 tablespoon cornstarch
- 2 tablespoons soy sauce low-sodium if you prefer
- 1 tablespoon oyster sauce optional for depth
- 1 tablespoon hoisin sauce for a hint of sweetness
- 1/2 cup beef broth or water
- 1 teaspoon sesame oil for finish
- Salt and pepper to taste
Instructions
- Prep the beef: Toss the sliced beef with a pinch of salt, pepper, and the cornstarch. This little coat makes it sear and stay tender.
- Heat the pan: Get a large skillet or wok screaming hot over medium-high heat. Add 1 tablespoon oil and swirl. You want a quick sizzle, not a calm spa day.
- Sear the beef: Add the beef in a single layer (work in batches if needed). Sear 1–2 minutes per side until browned but not mushy. Remove to a plate and rest.
- Stir-fry the veggies: In the same pan, add the remaining oil. Toss in onion and peppers; cook 2–3 minutes until they start to blister and soften. Garlic goes in last, about 30 seconds, just until fragrant.
- Make the sauce: In a small bowl, whisk soy sauce, oyster sauce, hoisin, and beef broth. Pour over the veggies. Stir to coat everything.
- Return beef to the pan: Add the beef back in. Toss quickly to coat and heat through. Drizzle with sesame oil and adjust salt/pepper. Serve hot.

Common Mistakes

– Skipping the cornstarch coat: You’ll miss that nice sear and the sauce won’t cling.
– Overcrowding the pan: If you dump all the beef at once, you’ll steam it instead of sear it. Sear in batches.
– Chopped peppers too thick: They stay crunchy and you miss the harmony with beef. Slice thin.
– Not letting the beef rest after searing: Resting keeps juices in; rushing leads to dry bites.
– Under-seasoning: A quick splash of salt at the right moment saves the day. Taste test as you go.
Simple Alternatives or Ingredient Substitutions
– Meat swap: Use ground beef for a faster, chunkier texture, or chicken thigh strips for a lighter option.
– Veggie swap: Add broccoli, snap peas, or mushrooms for variety.
– Sauce tweaks: If you like more tang, add a teaspoon of rice vinegar; for extra sweetness, drizzle a little honey.
– Gluten-free: Use tamari or coconut aminos instead of soy sauce.
– Heat level: For a kick, toss in a pinch of red pepper flakes or Sriracha.
– Leftover twist: Turn leftovers into uppercase “beef pepper fried rice” by mixing with cooked rice in the pan and adding a scrambled egg.

FAQ
Can I use a different cut of beef?
Beef flank or sirloin works best because they slice thin and sear quickly. If you use a tougher cut, marinate a bit longer or slice very thin to keep tenderness.
Is this dish spicy?
The version here is mild to moderate. If you want more heat, add a pinch of red pepper flakes or a dash of chili paste to the sauce.
Can I make this ahead?
Yes. You can prep the veggies and sauce ahead. Sear the beef and finish with the sauce just before serving to keep everything fresh and glossy.
What should I serve this with?
Rice is the classic pairing, but noodles or cauliflower fried “rice” also work great. A simple side of steamed greens keeps the meal balanced.
How long does it keep?
In the fridge, it’s best within 3–4 days. Reheat gently on the stove or in the microwave, adding a splash of broth if it’s too thick.
