Takeout is not always the fastest and easiest option, especially if you have a slow cooker at home. This kung pao beef recipe only takes 10 minutes to prepare and is a healthier version of the takeaway dish. Plus, the slow cooker won’t take ages to clean. Let’s get to cooking!

What Is Kung Pao Beef?

Kung pao beef consists of thinly sliced beef, vegetables, chili peppers, peanuts, and a special sauce. The original recipe comes from China and is made with chicken. Kung pao beef tastes sweet and sour and has a little kick.

It’s normally cooked in a skillet, but using a slow cooker will make things easier. Also, the slow cooker makes the meat more tender due to the gentle heat it provides. In addition, it helps all the flavors blend for an even better taste.

Tips and Tricks

To make the perfect kung pao beef in the slow cooker, you should let the meat cook first and then add the vegetables. This way, you won’t overcook the veggies and they’ll keep their nutrients. Plus, they’ll remain crunchy and add more texture to your dish.

You can use vegetables like bell peppers and broccoli, as they bring numerous health benefits and strengthen your immune system. Just remember to add the vegetables during the last 30 minutes of cooking.
