    How great is it to discover a new dish that takes little effort, but is enjoyed by all. This dish easily fits that bill.

    It can cook for long periods of time. So, you can make it in the morning and not worry about it again until dinner time. AND... It is versatile enough to be served different ways to help prevent dish fatigue.

    Dish fatigue: my "technical term" for how you feel about a dish you have made so many times you never want to see it again!

    🥣Instructions

    A bowl of Mongolian beef topped with green onion

    Lazy Mongolian beef is made with mostly shelf stable pantry items making it a great choice for those days when you haven’t planned ahead. The ingredient list includes:

    • beef strips
    • potato starch
    • soy sauce
    • beef broth
    • brown sugar
    • garlic
    • sesame oil
    • ground ginger
    • fresh red pepper
    • sesame seeds
    • green onion

    One great time saver is that this can be a "no-bowl" recipe. If you are using a slow cooker liner, it can be made right in the liner. If not, a zip lock bag works well. (You can, of course use a bowl if you choose!).

    For the laziest among us (me!!) add your beef strips and potato starch right into a liner or bag. Close tightly and shake to cover beef evenly in potato starch. Open the bag/liner back up, add all remaining ingredients except red pepper, sesame seeds and green onion.

    Close liner/bag tightly again to and shake to mix. Carefully open bag/liner and place it in your slow cooker (or dump contents of bag/bowl into slow cooker).

    Toss the red pepper slices in on top of beef mixture, cover and cook on low for 8 hours. When you are ready to serve, top with cut green onion slices and sprinkle with sesame seeds!

    🍽Serving suggestions

    This lazy beef recipe is delicious on its own. Since the sauce is a sticky one, you don't need anything to soak it up. However, the flavors of the dish still pair really nicely with rice, quinoa, and riced cauliflower. To mix things up a bit, try serving it over rice noodles, mashed potatoes or mashed cauliflower. It is also delicious served in lettuce wraps!

    😉Hints and Hacks

    1. This is a great dish if your people will be eating at different times. After the cooking time, turn your slow cooker to low and everyone can have a warm and filling meal, no matter what time they are ready to eat.
    2. To make this a gluten free recipe, switch out the soy sauce for Liquid Aminos.
    3. The longer cooking time of this recipe makes this an ideal dish for days you are away from home. There is nothing better than walking in to a home cooked meal after a long day!
    4. Looking to make this dish sugar free? Switch the brown sugar with a sugar substitute such as my favorite:  Swerve brown “sugar” erythritol.
    5. I always recommend the use of a slow cooker liner. Of course, this is an optional step. I like to purchase my liners in bulk for a less expensive per-piece price.
    6. In the market for a new slow cooker? I love mine!

        Hi Vicki,
        I made this recipe with potato starch due to a family food sensitivity so I have never tried it with corn starch. But it is my understanding that they are interchangeable. I would go for it! And, if you do, I would love to hear how it goes. Thank you!!
