In a large bowl, combine the coconut aminos, fish sauce, sesame oil, garlic, ginger, and crushed red pepper flakes using a whisk. Then add in the thinly sliced beef. Cover and let marinate for 10-15 minutes
Heat your cooking oil in a large skillet over medium/high heat
Add in the beef with marinade and cook for 5-10 minutes (or until just cooked), remove the beef with a slotted spoon and set aside. Bring the remaining liquid to a boil and then reduce to a simmer. In a small bowl, mix 1 Tbls tapioca starch with a Tbls of room temp water and then add into the sauce. Let simmer until thickened slightly
While the sauce is simmering, boil the broccoli florets for 1-2 minutes, then add into the sauce along with the beef. Stir to combine, add salt and pepper if needed. Top with sesame seeds and pepper flakes (optional)
Instant Pot
In a large bowl, combine the coconut aminos, fish sauce, sesame oil, garlic, ginger, and crushed red pepper flakes using a whisk. Then add in the thinly sliced beef. Cover and let marinate for 10-15 minutes
Turn Instant Pot to saute mode and add in the avocado oil in, then add in the beef with marinade and cook for 2-3 minutes. Then add in the beef broth, place the lid on and seal the steam valve. Hit pressure button and set to 10 minutes
When the timer goes off, do an immediate release of the steam. Add in the broccoli and tapioca slurry (1 Tbls Tapioca mixed with 1 Tbls room temp water) place the lid back on, let it sit in the natural heat for 5-10 minutes until broccoli is tender (stir it ocasionally and check the tenderness of the broccoli. I like mine to have a bit of crunch to it still.
Notes
*The Instant Pot version requires more liquid than the skillet version. This is so the beef will cook properly without getting a burn notice on your IP* I do not add any salt to this recipe because the fish sauce adds enough saltiness for us, but feel free to add some at the end if needed*If you are not doing a Whole30, feel free to use Tamari (gluten free soy sauce) instead of coconut aminos. Just be aware that this will also increase the sodium*To thicken the sauce, the recipe calls for tapioca starch. Arrowroot is also acceptable and Whole30 compliant. Cornstarch will work too, but is not compliant.
