Stir fries are one of my go-to’s for a quick midweek dinner. I love that you can throw everything into one pan, cook it over medium-high heat for a few minutes and you’re done! It can’t get any easier.

My family loves ordering beef stir fry with vegetables when we get Chinese takeout, and this homemade version of steak stir fry with peppers does not disappoint!

The peppers are cooked to a tender crispness and the steak is simply seasoned with garlic powder, salt, and pepper. Then, everything is tossed in an addictive sweet and salty sauce. The perfect combination!

This pepper steak stir fry is…

  1. Quick and easy to make. Ready in just 20 minutes, it’s perfect for busy weeknights!
  2. Family friendly. The sauce is slightly sweet and not at all spicy, so great for all taste preferences!
  3. One pan dish. Less fuss and less mess make clean up a breeze!

I think this recipe is just as good as the same dish served in many restaurants. I like to serve it with steamed rice, but it also goes great with fried rice or noodles. Saving time and money makes it all the better and I’m so happy to share this recipe with you!

Ingredients for steak and pepper stir fry prepped and labeled.

Steak stir fry sauce:

  • Soy sauce – A low-sodium one lets you better control how salty you want your dish to be.
  • Water
  • Cornstarch – Helps to thicken the sauce
  • Honey – Adds sweetness to the sauce and a delicious stickiness

For the stir fry:

  • Vegetable oil – You want to stir fry with a neutral oil that high as a high smoke point as you’ll be cooking at a medium-high/high heat. Canola and grapeseed oils are also good options.
  • Red and green bell peppers – If you prefer another color of pepper then feel free to substitute!
  • Flank steak – Sirloin steak and skirt steak would also work well here.
  • Garlic powder – Slightly sweeter and less intense than using raw garlic.
  • Salt and pepper – Season to your preferences. Remember, if you use regular soy sauce the stir fry sauce will already have a salty flavor, so taste it before you add more salt.

You’ll be amazed at how quickly this steak stir fry comes together! Before you start, gather all your ingredients and tools as the recipe moves fast!

Important Steps in Making a Good Stir Fry

If you haven’t tried stir-frying at home, not to worry, the technique is pretty straightforward! Think of it as being like sautéing but at a higher temperature. Here are some key steps to take to ensure your stir fry turns out perfectly every time: 

  • Prepare all of your ingredients in advance as stir frying moves quickly!
  • Cut your peppers and steak into similar sizes so they cook in the same amount of time.
  • Heat the pan and oil first before adding in the veggies and then the meat. You want everything to start sizzling once they meet the pan.
  • Keep it moving! Stir the ingredients with a wooden spoon or spatula to prevent them from sticking to the bottom of the pan or burning.

Expert Tips

Cut steak across the grain. Flank steak benefits from being cut across the grain. Cutting it this way will make it tender and easier to chew. So how do you cut across the grain? Look at your piece of steak to see which way the muscle fibers (grain) runs. You want to cut in the opposite direction. 

Freeze beef first before slicing. It can be tricky to thinly slice steak, but this tip works really well for me. Put the meat into the freezer for 30 – 60 minutes to partially freeze before slicing. It’s soooo much easier to cut the meat when it’s firmer.

Frequently Asked Questions


Why is my pepper steak tough?


It’s true that flank steak or any stir fry steak can be a bit tough, but there are a couple of things you can do to help. 

The first thing to do is to make sure you’re cutting the meat across the grain. This will help to shorten the fibres to make the meat less chewy.

The second thing to remember is to season the beef with salt. Salt is a tenderizer. Seasoning the large piece of meat before you slice it can make it a bit easier.

How do you store leftover steak stir fry?


This stir fry can be stored in an airtight container for up to 3 days. To reheat it, add 1 or 2 tablespoons of water before heating it up in the microwave. The sauce will thicken up in the fridge, so adding a splash of water will help to loosen it up.

I’ve been making this pepper steak recipe for my family for over a year now and am hoping you and yours will enjoy it as much as we do; it’s my husband’s most-requested dinner!
