Instant Pot Mongolian Beef and Broccoli (Easy Weeknight Dinner Recipe)

Inside: A quick and easy Instant Pot Beef and Broccoli recipe that is so tender you will never want to order Chinese take-out again!

There are two things in my kitchen I am falling more and more in love with every single day.

If it isn’t obvious, those two things are:

My Instant Pot and homemade Chinese food.

So this week when I finally figured out how to make my favorite take-out meal, Mongolian beef and broccoli in my pressure cooker, I was just too stinking excited.

Usually Tuesday nights are take-out nights around here.

I would love to say that we participate in Taco Tuesday every single Tuesday, but truth be told, most Tuesdays are so hectic around here that they in all honesty are take-out Tuesdays.

After speech therapy and swimming lessons most Tuesdays we swing by the Panda. It’s so predictable that they even have our order memorized. One order of Pineapple Chicken, a couple orders of orange chicken, and one family sized beef and broccoli.

Goodbye Panda and HELLO homemade.

I think we might just have a new Tuesday tradition <3
