Pepper Steak with Onion + Tomatoes
If you travel to China, the chances of finding beef and bell pepper stir fry on a restaurant menu are slim to none. This is because the pepper steak recipe really isn’t Chinese at all!
It’s what some people call American-Asian, or Americanized Asian. Other foods like this are chop suey, General Tso’s chicken, and crab rangoon. They are Asian-style foods recreated by Westerners.

Ingredient notes and substitutions
What’s the best cut of beef for a stir fry?
Because the meat is cooked quickly and over high heat, it’s important to use a lean cut of beef. Good choices are flank steak and top sirloin.
Unfortunately, many packages of “stir fry meat” in U.S. grocery stores include beef with connective tissue. These cuts require braising to break down the collagen, so they aren’t a good choice for stir fry recipes.
- Dark soy sauce– This ingredient is much different than traditional light, all-purpose soy sauce. It’s very thick, almost black in color, and is fermented/aged rather than being chemically processed like all-purpose soy sauce.
If you can’t find dark soy sauce, hoisin sauce or oyster sauce could be used instead. For more info, Epicurious has a nice article about the different types of soy sauce and how they’re made.
- Bell peppers– It may be obvious, but a pepper steak recipe without bell peppers is just a steak stir fry. I like to use green peppers but for a sweeter flavor, feel free to use red, yellow, and/or orange peppers.
Frozen bell peppers are great for adding to soups and casseroles, but they do not work well in a stir fry. They don’t have a crispy crunchy consistency like fresh peppers do. Besides, they become mushy when you try to stir fry them.
- Onion and tomato– As mentioned earlier, I prefer pepper steak with onion, and fresh tomatoes add a nice pop of color, plus another layer of flavor to the beef and peppers.
White onion is the variety I use. It isn’t as sweet as yellow or red onion are, which is why I prefer it. However, either of those are fine to use if you’d like.
If you don’t care for onions or tomatoes, feel free to leave one or both of them out.
Beef Stir Fry FAQ
If you’re using a cut of steak or beef with too much connective tissue, the quick cooking method for stir frying won’t be long enough to tenderize the meat, leaving it very chewy.
Other reasons for a chewy steak stir fry include over cooking the meat, and/or not using a high enough heat.
There are several different names for pepper steak stir fry, including pepper beef. However, there is another Asian stir fry called black pepper beef, which is completely different from the steak and bell pepper stir fry.
Serving suggestions for pepper steak with onion and tomatoes
I think that beef and bell pepper stir fry goes really well with rice, but some people like to serve it over Asian rice noodles or lo mein.
Because there are already vegetables in the stir fry, you really don’t have to serve a veggie on the side. That being said, a crisp, cool sunomono salad (without the shrimp) or Chinese cucumber salad would compliment the meal.
For an appetizer, something like a light broth soup, vegetable egg rolls or spring rolls would be a great addition.
