30 Minute Mongolian Tenderloin is an old favorite using thinly sliced beef or pork tenderloin. It is tossed in a sweet soy garlic ginger sauce and can be enjoyed as is or over rice, quinoa, or noodles. I’ve included slow cooker and instant pot methods.

30 Minute Mongolian Tenderloin


This recipe cooks quickly and makes a great weeknight meal. It’s a good meal to prep ahead if that’s your thing. You can use any protein. We like beef, pork, and chicken. The sauce is the real star so it enhances any meat. 

I also like to change the vegetables. Instead of bell peppers, I often use broccoli florets or a bag of frozen stir-fry vegetables. 

If you follow a low-carb diet amp up the veggies. Otherwise, you can stretch 30 Minute Mongolian Tenderloin by serving it over rice or noodles. 

As well, you can easily double the recipe for more guests or teenage boys. 😏



  • Vegetable oil.
  • Meat. You can use pork or beef tenderloin. Beef tenderloin is pricey, you can also use flank steak. It’s actually very good with chicken too.
  • Cornstarch.
  • Salt. For this recipe, I like to use coarse salt and pepper.
  • Black pepper.
  • Red bell pepper. 
  • Green bell pepper.
  • Onion.
  • Bella mushrooms.
  • Red pepper flakes.
  • You can add broccoli florets if desired.
  •  Sesame seeds.
  • Green onions.
  • Garlic paste. Garlic paste and Ginger paste are located in the produce section of the store. Furthermore, if you can’t find it you can always mince fresh garlic and ginger.
  • Ginger paste. 
  • Soy sauce. I highly recommend you use low-sodium soy sauce. As well, you can sub tamari or liquid aminos which are better for you.
  • Brown sugar.
  • Water.
30 Minute Mongolian Tenderloin


  1. First, turn your Instant Pot to “saute”.
  2. Add 1 tablespoon of oil and when the oil is hot, add the meat. Sear it on both sides in batches. If needed, add more oil between batches. Be sure not to crowd the meat while searing it or it’ll steam instead.
  3. When it’s all seared hit “cancel” on the Instant Pot.
  4. Return all meat to the Instant Pot and pour sauce over it.
  5. Place lid on and set to Manual (High Pressure) for 10 minutes. Double-check that the valve is in sealing position.
  6. Pressure release first when the time is up.
  7. Garnish with sesame seeds and greens onions before serving.

  1. Add all the sauce ingredients to the slow cooker and stir.
  2. Dip the tenderloin in cornstarch then add it to the sauce in the slow cooker.
  3. After all the protein is added to the slow cooker, gently stir to coat all the meat in the sauce.
  4. Cover and cook on low for 4-6 hours or until the meat is cooked through and the sauce has thickened. 
  5. Garnish with sesame seeds and greens onions before serving.
Mongolian Tenderloin


  • First, to thinly slice the tenderloin, place the meat in the freezer for 30 minutes before cutting. Next, cut it in half down the center and slice each half into slices that are ¼-inch thick. Try to get all the slices the same thickness for uniform cooking.
  • Be sure the oil is hot, about 350°F is perfect. Test by placing a wooden spoon into the oil, if it bubbles gently it is ready.
  • The cornstarch coats the meat and gives a slightly crunchy crust which better holds the sauce.
  • You want the peppers tender-crisp. Do not fully soften them. A slight crunch is perfect.
  • Cornstarch and water make a slurry that thickens the sauce. The sauce will thicken more as it cools.
  • Store in a sealed container in the fridge for up to 3 days.
