This Flank Steak Stir Fry is perfect for a midweek meal when asparagus are in season. It’s easy enough to make and everyone raves about it!
When it comes to stir-fry, it’s all about the prep. The dish itself cooks up so quickly that you need everything prepped and ready to go before you start adding the elements to the hot pan.
A couple elements of the recipe to note. We are blanching the asparagus in boiling water a couple minutes. This will ensure that the asparagus will be cooked in the short stir-frying time.
Flank steak is a lean cut of meat, which can be tough and chewy if it isn’t cut properly (across the grain of the meat) for this dish. It helps to freeze the meat for a few minutes before starting the recipe to make it easier to slice thinly.
Flank Steak Stir Fry with Asparagus and Red Pepper Recipe
If you are planning to serve this dish with rice, in a separate pan, prepare 2 cups of white rice, following the instructions on the rice package.
Ingredients
- 3 Tbsp canola or peanut oil
- 1/2 lb asparagus, trimmed, cut on the diagonal into 1 1/2 inch lengths (about 1 1/2 cups)
- 1 lb of flank steak, sliced in half lengthwise (along the grain) and then cut into thin strips (across the grain), 2 inches long and 1/4 inch wide (put the steak in the freezer for 15 minutes before slicing to make it easier to slice)
- 1 red bell pepper, seeded, de-ribbed, and cut into thin strips 2 inches long and 1/4 inch wide
- 2 teaspoons of cornstarch dissolved into 3 Tablespoons of water
Stir Fry Sauce
- 3 Tbsp soy sauce (use gluten-free soy sauce for gluten-free version)
- 1 teaspoon finely chopped, peeled, fresh ginger
- 1 small clove garlic, minced
- 1 green onion, including green tops, chopped
- 1/2 teaspoon chili oil
Method
1 Blanch the asparagus: Fill a medium sized saucepan halfway with water and bring to a boil. Blanch the cut asparagus for 2 minutes. Drain, rinse with cold water to stop the cooking, and set aside.
2 Assemble stir fry sauce: In a small dish, stir together the stir fry sauce ingredients—soy sauce, chopped ginger, minced garlic, chopped green onion, chili oil—and set aside.
3 Stir fry asparagus: Heat 1 tablespoon of oil in a wok (or a thick-bottomed pot that can handle high heat) on high heat until shimmery. Add the asparagus and fry, stirring constantly, for 2 minutes or until lightly browned. Remove the asparagus from the pan and set aside.
4 Stir fry beef strips: Heat another tablespoon of oil in the pan on high heat until shimmery. Stir fry the beef strips in batches, for 2 to 3 minutes per batch, until they are browned but still a little pink inside.
5 Stir fry bell pepper: Return the first batches of beef strips to the pan along with the bell pepper strips. Stir and toss over high heat until the bell pepper strips are just beginning to wilt, 1-2 minutes.
6 Add cornstarch slurry and stir fry sauce: Quickly stir the cornstarch liquid and add it to the pan along with the stir fry sauce. Cook until sauce thickens, 1-2 minutes.
Return the asparagus to the pan, toss to evenly coat and serve with steamed white rice (unless you are going low-carb, in which case, leave out the rice).

Flank Steak Stir Fry with Asparagus and Red Pepper

Thanks for the reminder to freeze the meat for a bit, really helps, it looks like a great recipe, I have my meat marinating as I write. I always add broccoli & mushrooms.

Tried this recipe tonight. I like how easy it is to make, but the end result was rather bland for my palette. I’m not sure what I’ll do differently next time – maybe add sambal olek like the another reader suggested. Dunno. I’d make this recipe again, though, even with the way it’s outlined today.

You could always use sriracha or up the chili oil, PL—customize to your taste! Consider this a template! Thanks for the feedback.
I saw this on Instagram and had to make it. It was really good. I didn’t have green onions for the sauce, so I finally chopped half of a small yellow onion and used that instead. I also used sriracha instead of chili oil. I did have all the other ingredients. I would definitely make this again.

This recipe is so easy I cooked it in my airstream. Made this recipe with organic asparagus and red peppers.
I used an organic grass fed tenderloin. The sauces would work with any mix of
Veggies or meat. I plan to use this again and again.
