My recipe for slow cooker sweet and spicy teriyaki beef is one of my favorite and reliable recipes to use in my Crockpot. It can take a tougher cut of beef and make it nice and tender. With a more tender cut, it practically melts in your mouth.

I love the convenience of the automatic settings and find the temperatures of high and low to be pretty accurate. This sweet and spicy teriyaki beef was done just under 4 hours and I left it on the keep warm setting for another 1 ½ hours and it was perfectly fine.
This meal was so easy, with minimal chopping, this low carb meal gave us leftovers and little clean up. Truly a win-win!

Notes
** I served my husband's meal over basmati rice. For mine, I served it over cauliflower rice. It was so delicious I could have just eaten the 'rice' and sauce. It had the right amount of sweetness with some heat to balance the flavor.
**To keep the sauce lower carb, use sugar substitute and try arrowroot powder instead of cornstarch and use beef broth instead of gravy.
