- Beef steak (20 oz): Choose tender cuts such as flank, skirt, or sirloin for a juicy texture.
- Sauce ingredients: Hoisin sauce, soy sauce, rice vinegar, and brown sugar contribute to a flavorful mix. Feel free to swap hoisin sauce for oyster sauce if preferred.

Here are some substitutions to consider:

- Use tamari or coconut aminos as a gluten-free option for soy sauce.
- Honey or maple syrup can replace brown sugar, depending on dietary needs.
How to Make Easy Beef Stir Fry
Follow these easy steps to create your stir fry:
- If you’re starting with a whole piece of beef, freeze it for about 30 minutes to simplify slicing. This helps you cut the meat into thin (1/4-inch) strips, crucial for tender stir frying.
- Combine the beef strips in a bowl with sesame oil, cornstarch, baking soda, and salt. Massage the mixture into the meat and let it marinate for at least 15-30 minutes to enhance tenderness and flavor.
- While the beef marinates, prepare the sauce by mixing the hoisin sauce, soy sauce, rice vinegar, and brown sugar in a separate small bowl. In another bowl, mix cornstarch with a bit of water to create a slurry for thickening the sauce during cooking.
- Next, mince the garlic and ginger, slice the bell peppers and onion into strips, and chop the green onions into rounds and long strips for garnish.
- Heat 1/3 of the vegetable oil in a large skillet or wok over medium-high heat. Add the marinated beef in a single layer and cook for about 2-3 minutes per side until browned and cooked through. You may need to work in batches to avoid overcrowding the pan.
- Remove the beef and add the remaining oil to the skillet. Stir-fry the bell peppers and onion until tender-crisp, about 2-3 minutes.
- Lower the heat slightly and add the garlic and ginger, sautéing for 1-2 minutes until fragrant.
- Stir in the sauce and cornstarch slurry, cooking for another 1-2 minutes until the sauce thickens to a glossy consistency. Adjust the thickness by adding more water or beef broth as needed.
- Return the cooked beef to the skillet, stir in the green onions, and combine well before serving.
Expert Tips for Success
- Always cut beef against the grain to create tender strips that are easier to chew.
- Maintain a high cooking temperature to achieve a nice sear on your beef while keeping everything juicy.
- Allow the beef to marinate adequately for a significant difference in texture and flavor.
- Feel free to mix and match your favorite vegetables, ensuring they are cut to similar sizes for even cooking.
Variations
If you want to change things up, consider:
- Making a spicy version by adding red pepper flakes or Sriracha to the sauce.
- Incorporating additional vegetables such as mushrooms, carrots, or baby corn for varied textures.
- Using different protein options like chicken, shrimp, or tofu for a vegetarian alternative.
Serving Suggestions
This Easy Beef Stir Fry pairs wonderfully with:
- Steamed rice (jasmine or basmati) or fried rice for a heartier meal.
- Noodles such as chow mein or soba for a different texture and flavor.
- A fresh salad, like an Asian cucumber salad, to balance out the meal.
Storage, Freezing, and Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. You can also freeze the stir fry for up to 3 months; just let it thaw overnight in the fridge before reheating. For reheating, a skillet works best to retain texture, but a microwave can be used—just heat in 30-second increments and stir in between to avoid overcooking the vegetables.
Frequently Asked Questions
Can I use frozen vegetables for stir fry?
Yes, frozen vegetables can be a convenient alternative. Remember to thaw them beforehand to ensure even cooking without excess water.
What is the best cut of beef for stir fry?
Tender cuts like flank steak and sirloin are recommended as they cook quickly and remain tender. Avoid tougher cuts like chuck or brisket, which require longer cooking times.
How can I make my stir fry sauce thicker?
Mix more cornstarch with water to create a slurry and stir it into your sauce as it cooks. This will effectively thicken the sauce; remember to whisk it well to avoid lumps.
Can I make this dish gluten-free?
Absolutely! Substitute soy sauce with tamari or coconut aminos and double-check your hoisin sauce to ensure it meets dietary needs.
Is it necessary to marinate the beef?
While not absolutely necessary, marinating enhances the flavor and tenderness of the beef. Taking this extra time is worthwhile for a better result.

Easy Beef Stir Fry Recipe
Ingredients
- 20 oz beef steak Use tender, lean cuts like flank steak, skirt steak, or flat iron.
- 1 Tbsp sesame oil
- 1 tsp cornstarch
- 1/2 tsp baking soda
- 1/2 tsp sea salt
- 3 Tbsp hoisin sauce Or oyster sauce.
- 2 Tbsp soy sauce Regular or low-sodium.
- 2 Tbsp rice vinegar Or apple cider vinegar/Shaoxing wine.
- 1 Tbsp brown sugar Or honey/maple syrup.
- 1 Tbsp cornstarch Or arrowroot flour/tapioca starch.
- 1 Tbsp water
- 11 oz bell peppers Mixed colors.
- 4 oz onion 1 small.

- 1/4 cup vegetable oil Or canola oil.
- 0.3 oz garlic 2 cloves.
- 0.2 oz ginger 1/2 Tbsp minced.
- sesame seeds To taste, raw or toasted.
Instructions
- If you're not using pre-sliced beef, first freeze it for 30 minutes to make it easier to cut.
- Cut the beef into thin (1/4-inch) strips, against the grain (across the long lines of muscles in the meat).
- Once cut, add the beef to a bowl with the sesame oil, baking soda, cornstarch, and salt, and mix well, massaging it with your hands. Set aside for 15-30 minutes to "marinate".
- Meanwhile, mix the sauce ingredients (minus the garlic and ginger) in a small bowl. Mix the cornstarch with water into a slurry in a separate bowl.
- Mince the garlic and ginger. Cut the green onions so the green parts are cut lengthwise (into long strips) and the white parts are sliced into rounds. Slice the bell peppers (removing the ribs/seeds) and onions (pole to pole) into even-sized strips.
- Add about 1/3 of the oil to a large skillet/wok over medium-high heat. Once hot, add the beef in a single layer (cook in batches if necessary) and cook for 2-3 minutes per side, untouched, until it's no longer pink.
- Add another 1/3 of the oil to the pan and stir-fry the peppers and onions until tender-crisp (2-3 minutes).
- Heat the remaining oil, reduce the heat to medium, and sauté the garlic and ginger for just 1-2 minutes.
- Add the stir-fry sauce and cornstarch slurry (mix/whisk well beforehand) to the pan and cook for 1-2 minutes, stirring constantly, until it becomes glossy and thickens. If the sauce isn't thick enough, add more cornstarch slurry. If it's too thick, add water/beef broth.
- Add the cooked ingredients back into the pan with the green onions, stir, and serve – enjoy optionally sprinkled with sesame seed.
