Turn instant pot onto “sauté” mode and add avocado or olive oil.
Once the oil is sizzling, sear sliced beef (about 30 seconds-1 minute on each side) in batches, ensuring not to overcrowd or overcook. Transfer to a plate once browned
Once all beef is browned and on the plate, add minced garlic to the instant pot and sauté until fragrant, about 1 minute
Add in the beef broth, ginger, coconut amino, sesame oil, onion powder, red pepper flakes, salt, and pepper. Add beef and juices from plate to the instant pot, close the lid, and set to “sealing”
Select the manual and set the timer for 10 minutes
While beef and sauce are cooking, place broccoli florets in a microwave-safe dish filled 3/4th’s with water. Microwave for 3 minutes until lightly steamed for al dente broccoli. Drain water and set aside. Mix in with the beef after cooking. *See notes for an additional way to cook the broccoli
Once the beef is done, do a quick release, and put the instant pot back into “sauté” mode
Slowly add in arrowroot flour, using a fork to whisk into the liquid as you add it. Add in broccoli and continue stirring as the sauce thickens
Remove beef and broccoli with a slotted spoon and arrange in a large serving dish or meal prep containers. Allow the remaining liquid to continue simmering and thickening
Once it’s thick and bubbling, pour the sauce over beef and broccoli
Garnish with sesame seeds, green onions or additional red pepper flakes
