PIN THIS RECIPE FOR LATER

I know sometimes it seems like a tragedy to put steak in the slow cooker.

When I sent my husband grocery shopping for this dish, I requested sirloin steak — a nice, lean, middle of the line steak. He purchased striploin steak — an incredible, but pricey, cut of steak we reserve only for the grill.

The crockpot does such an amazing job at tenderizing less expensive cuts of meat, there is really no need to go all out here!

Just throw everything in and let it cook away for a good part of the day and know that dinner is taken care of.

This Slow Cooker Mongolian Beef has a rich, dark sauce — not too sour or too spicy, compared to the Honey Balsamic Pulled Pork or the Sweet & Spicy Coconut Grilled Chicken. The flavours are a lot more subtle in this dish, and it goes perfectly over rice or noodles.

I love using my slow cooker for supper when I’m going to be home all day. Maybe that sounds weird to you, as it’s such a great appliance to use when you’re going to be gone all day. But sometimes I just love having a full day to “relax” (like that ever happens) and not even having to make supper when 5:00 rolls around. It’s about as good as a staycation gets for us these days.

So I put this in the slow cooker day on a rainy Monday off from work and spent a lazy afternoon on the couch — it was the perfect end to a long weekend!

The recipe makes a good amount of sauce. We like a lot of sauce, perfect for spooning over whatever else is on your plate!

How to Make Slow Cooker Mongolian Beef

• I have made this recipe and browned the beef first in a frying pan before adding it to the slow cooker. It’s an extra step that isn’t necessary, but the steak will hold in the juices instead of diluting the sauce.
• If you don’t like your peppers and onions soft, feel free to just toss them in for the last hour — I put mine in for the whole cooking time. Once again, laziness. Do whatever works for you, and whatever your family prefers.
• If you like things spicy, feel free to add in a pinch of red pepper flakes when you’re stirring up the sauce!
