Weeknight Mongolian Beef Stir-fry

Meal planning is hard you guys and I struggle with it more often than you would think.

I’ll spend hours meal planning and creating a grocery list on Saturday, shop on Sunday evening or early Monday morning so I can cook dinner Sunday through Thursday. Friday and Saturday dinners are left up in the air for whatever we feel like or leftovers from the week. Typically what happens is that what meal I schedule to make isn’t necessarily what I feel like making come Wednesday or Thursday. The struggle is real. But each week I do try to plan for a stir-fry dinner for at least one of those nights — sometimes twice.

As of lately, I’ve been making this Mongolian beef stir-fry and my family loves it. It could be the crispy edges of the thinly sliced steak, or the sweet yet savory, garlicky ginger sauce. Either way, my family will eat. it. all. Malloree will just have some saucy steak and roasted broccoli in a bowl (still not a fan of rice) and Haileigh, Pat and I load our bowls up and drizzle ours with a little extra Sriracha for a spicy kick.

Weeknight Mongolian Beef Stir-fry

All in all this is a easy dinner that can be made any night of the week. Prep ahead, slicing the steak, making the sauce and chopping any veggies in advance and you can save yourself even more time.

Who doesn’t love the sound of that?

thinly sliced beef

When making any beef stir-fry recipe, I slice the steak really thin. This makes it quick to cook, easy to pick up with chopsticks [not that you will find me using them] and let’s be real– easy to chew. To make this task a little easier, you can place the steak or steaks on a plate or small sheet pan and flash freeze for about 10 minutes before slicing. It’s easier to slice ultra-thin strips of steak (or chicken!) when it’s slightly frozen.

As far as what cut of meat to use for stir-fry, I use top loin or sirloin steaks.

Flank steak may be used and you can find it listed in most stir-fry recipes, but Pat picks up on an irony taste in the meat so I don’t typically use it for stir-fry’s.

Sliced beef tossed in white pepper and cornstarch

Place 1-1/2 pounds thinly sliced steak into a bowl, season it with 1/2 teaspoon of white pepper and 3 tablespoons cornstarch. Use tongs to toss and coat evenly. Set that off to the side while you quickly make the sauce.

Mongolian beef stir-fry sauce in bowl.

Into a small bowl, add 1/3 cup of dark brown sugar and 2 tablespoons of both finely minced fresh ginger and garlic. Next add in 1 cup of beef broth, 1/2 cup of low-sodium tamari [or low-sodium soy sauce], 1/2 teaspoon to 1 teaspoon [or more] of Sriracha hot sauce. Whisk to combine and set off to the side.

Working in batches cooking the beef in oil.

Heat 2 tablespoons of extra light olive oil or coconut oil in a large wok or 12-inch chefs pan on medium-high heat. Working in batches, evenly place a single layer of the steak into the hot pan. Cook about 2 minutes a side or until the edges are a deep golden color and are crispy.

A super hot pan is essential to making the steak get those caramelized edges.

Transfer cooked beef to a paper towel lined plate.

Transfer the cooked steak to a paper towel lined plate and repeat, in small batches, with the remaining steak.

remove most oil from pan and pour in sauce.

Carefully use some paper towel to wipe majority of the oil out of the pan. Leaving a little of the stuck on bits is fine, then pour in the sauce.

Simmer until thickened

Bring to a boil and while stirring, slowly pour in a cornstarch slurry [1 tablespoon cornstarch plus 1 tablespoon cold water].

add crispy beef back into pan with sauce.

Once thickened, add in the crispy fried steak.

Toss beef in sauce

Toss to combine and serve immediately. Adding the steak right before serving will help maintain the crispy texture.
