Some meals just belong in your regular rotation, and this pepper steak stir fry is one of them. It’s the kind of dish you turn to on a busy weeknight when you want something comforting without spending hours in the kitchen.
As the steak sears and the peppers soften, the pan fills with a rich, savory aroma—ginger, garlic, and soy sauce mingling into something instantly satisfying and familiar.
This has become a go-to in my kitchen when I’m craving a homemade dinner that feels hearty but effortless. The flank steak stays tender, the bell peppers bring natural sweetness, and the sauce ties everything together with just the right balance of salty and sweet.
Serve it over warm rice or toss it with noodles, and you’ve got a reliable, crowd-pleasing meal that disappears fast—no matter how much you make.
For Pepper Steak Stir Fry
- Flank Steak – Thinly sliced flank steak cooks quickly and stays tender, making it ideal for high-heat stir frying.
- Red Bell Pepper – Adds natural sweetness and vibrant color to balance the savory steak.
- Green Bell Pepper – Slightly more earthy than red peppers, it adds depth and contrast.
- Oil (Olive, Avocado, or Vegetable) – Used to sear the steak and sauté the peppers without sticking.
For the Stir Fry Sauce
- Garlic – Brings bold, aromatic flavor that forms the base of the sauce.
- Fresh Ginger – Adds warmth and a subtle bite that brightens the dish.
- Soy Sauce – Provides salty, umami-rich flavor that ties everything together.
- Brown Sugar – Balances the soy sauce with a touch of sweetness.
- Cornstarch – Thickens the sauce so it coats the steak and peppers evenly.
Easy 30-Minute Steak Stir Fry
Notes
Ingredients
- 1 tbsp oil olive, avocado or vegetable
- 1 large red bell pepper cut into thin strips
- 1 large green bell pepper cut into thin strips
- 2 lbs flank steak cut into thin strips
- 2 garlic cloves pressed
- 1 tbsp fresh ginger grated
- 1/3 cup soy sauce
- 2 tbsp brown sugar
- 1 tbsp corn starch
Instructions
- Combine all of the sauce ingredients in a small bowl, whisking until smooth. Set aside.
- Heat a wok or large skillet over medium heat with the oil. Add the sliced bell peppers and sauté until lightly browned, about 3 minutes. Transfer the peppers to a plate and reserve.
- Increase the heat to high. Add the beef strips to the pan and cook until nicely browned.
- Return the bell peppers to the pan, then pour in the prepared sauce. Continue cooking for 2–4 minutes, allowing the sauce to thicken and coat the steak and vegetables.
- Remove from the heat and serve with your favorite grain or noodles.
1. Can I use a different cut of beef?
Absolutely. Flank steak is my go-to because it cooks fast and stays tender, but skirt steak or sirloin work just as well. The real trick? Slice the beef thinly and against the grain. Do that, and you’re pretty much guaranteed tender bites every time.
2. What’s the best thing to serve this with?
You can’t go wrong with a bowl of steamed rice—it soaks up that glossy sauce beautifully. Rice noodles are also great, and if you’re feeling virtuous, cauliflower rice or quinoa both work nicely too.
3. How do I stop the peppers from overcooking?
Keep the slices nice and even, and don’t walk away from the stove. A quick sauté is all they need—you’re after tender with a bit of bite, not soft and soggy. Taking them out of the pan early (then adding them back later) is the secret here.
4. My sauce looks thin—what happened?
Don’t panic! Make sure the cornstarch is fully mixed into the sauce before it hits the pan. Once it’s bubbling on high heat for a minute or two, it will thicken up nicely and cling to the steak just like it should.
5. Can I make this ahead of time?
Yes, and it reheats surprisingly well. Store leftovers in the fridge for up to 3 days. When reheating, add a small splash of water to loosen the sauce and warm it gently in a skillet—good as new.
