Healthier Version Of Chinese Stir Fry
This easy stir fry is inspired by Chinese takeout but made without the usual processed ingredients like cornstarch, hoisin sauce, oyster sauce, or added sugar.
While shopping at Sprouts, I spotted grass-fed beef strips and grabbed a package. I had a few peppers at home and decided to use the same marinade from my Top Round Stir Fry, adding vegetables to make it a complete meal.
Lately, I’ve been eating low-carb and looking for more ways to add protein. This one-pan dish turned out filling, and the leftovers lasted for a few meals. The marinade does contain orange juice, which adds a few carbs, but most of it gets discarded.

For The Steak
I'm using grass-fed sirloin strips of beef from Sprouts Farmers Market. You can sub skirt steak, flank steak or rib-eye, or any other steak, cut into thin strips, about ½-inch wide.
Publix has Top Round strips in the case and they're good and relatively inexpensive.

What You Need
For the Marinade:
- ¼ cup orange juice
- 4 tablespoons coconut aminos or two tablespoons tamari GF soy sauce
- Juice of 1 lemon
- 1 tablespoon avocado or olive oil
- 1 teaspoon fresh ginger, grated
- 2 garlic cloves, minced
- ¼ cup chopped parsley
- ½ teaspoon red pepper flakes
For the Stir Fry:
- 1 pound sirloin or other steak, cut into ½ strips
- 1 tablespoon olive oil
- 1 green bell pepper, sliced thin
- 1 red bell pepper, sliced thin
- 1 yellow onion, sliced thin
- 2 green onions (scallions), sliced diagonally
- 1 tablespoon sesame seeds (optional, for garnish)
- Salt and pepper, to taste

How To Make Stir Fry Pepper Steak
- In a large bowl, whisk together orange juice, coconut aminos or soy sauce, olive oil, ginger, garlic, and red pepper flakes.
- Add the beef strips to the marinade. Cover and refrigerate for at least 15 minutes or up to 24 hours for deeper flavor.
- Heat 1 tablespoon of olive oil in a large skillet or wok over medium-high heat until shimmering. Add green pepper, red bell pepper, and onion slices. Season with salt and pepper. Sauté for 3-4 minutes, stirring frequently, until slightly softened but still crisp. Remove the vegetables from the pan and set aside.
- Add another tablespoon of oil to the hot pan. Remove beef from the marinade, letting excess liquid drip off. Add the beef strips to the skillet in a single layer. Season with a little salt and pepper. Sear for 2-3 minutes per side until browned.
- Return the peppers and onions to the pan. Toss everything together and cook for another 2-3 minutes until the beef is cooked through.
- Remove from heat. Sprinkle with chopped green onions and sesame seeds.
- Serve hot with lemon wedges.

What Goes with Pepper Steak

- steamed brown rice

Storage and Reheating
Allow the stir fry to cool completely before storing. Transfer to an airtight container and refrigerate for 3-4 days. For extended storage, freeze in a freezer-safe container for up to 3 months. Label with the date for reference.
Reheat in a skillet over medium heat. Add a small splash of water or broth to the skillet to prevent sticking, then add the stir fry. Stir frequently and heat until warmed through about 5-7 minutes.
Transfer a portion to a microwave-safe dish, cover loosely with a microwave-safe lid, and heat in 30-second intervals, stirring between each, until hot.

FAQs for Beef Stir Fry With Peppers and Onions
Marinate the beef for at least 30 minutes to allow the flavors to absorb, and cook on medium-high heat to quickly sear the meat and lock in its juices. Keep the veggies crisp by stir-frying them until-crisp-tender so they retain a slight bite.
If you don’t have coconut aminos, low-sodium soy sauce or tamari (a gluten-free soy sauce) can be substituted. Use 2 tablespoons, as they contain more sodium than coconut aminos.
Add extra red pepper flakes or a sliced chili pepper to the marinade or during cooking to give the dish a spicy kick.
