This Pepper Steak stir fry has that saucy umami flavor you love from your favorite Chinese spot, but it’s made right at home in under 30 minutes. It's a weeknight recipe win to be sure!
Pre-recipe note: do not add extra salt while cooking, the soy sauce and beef broth add just the PERFECT amount of salt. If you are salt sensitive use a low sodium soy sauce and/or low sodium beef broth.
Whisk together sauce ingredients until smooth. Set aside.
¾ cup beef broth, ½ cup soy sauce, 2 cloves garlic, 2 tablespoon cornstarch, 1 tablespoon brown sugar, 1 teaspoon ginger
Pat steak pieces dry with a paper towel. Heat 1 tablespoon oil in a large 12" skillet over high heat.
Cook the steak in 2 batches so it sears and doesn't steam. Sear half the steak for about 1 minute per side. Remove to a plate and repeat with remaining steak. Remove steak from skillet and set aside.
1½ lbs flank steak
Add the remaining 1 tablespoon oil to the skillet. Sauté the peppers and onion until just tender, about 4 to 5 minutes.
1 red bell pepper, 1 green bell pepper, 1 medium yellow onion
Return the steak and any collected juices to the pan with the peppers, sprinkle in black pepper to taste.
Give the sauce a quick stir to reincorporate any settled corn starch, pour it into the pan, and stir to combine. Cook, stirring occasionally, until it thickens and coats the meat and vegetables, about 1 to 2 minutes.
Serve hot over rice or noodles. Optionally finish with a sprinkling of chopped green onions or sesame seeds.We love to use frozen rice that microwaves for a few mintues to keep this a SUPER EASY weeknight dinner. It is also excellent over ramen noodles (discard the flavor packet).
Storing
Store cooled Pepper Steak in an airtight container in the refrigerator for up to 4 days.
Freezing & Reheating
Freeze cooled pepper steak in an airtight container with some of the sauce for up to 3 months. Thaw overnight in the refrigerator. Reheat in a skillet over medium heat with a splash of water or beef broth. Stir occasionally until warm. (about 5-7 minutes)
Notes
Flank steak can be wonderfully tender when cooked just right—aim to avoid overcooking, as that has the biggest impact on texture. While a dark sear is nice, keeping the steak juicy and tender is the real key to success, especially for new cooks.
Dry your steak pieces as much as possible before adding to the pan to get the quickest sear without overcooking.
Choose a large skillet (12") to cook your steak and peppers. If you crowd the pan they will steam instead of fry.
Do not add extra salt while cooking, the soy sauce and beef broth add the perfect amount of saltiness to the Pepper Steak.
