Slice the broccoli into about 1 inch slices. They should look like little trees and there is no need to be exact here. Coat the broccoli in avocado oil, garlic powder, salt, and pepper.
Lay the broccoli flat in the air fryer or on a sheet pan if you are using the oven. Air fry on 350 degrees for about 11 minutes, checking at 5 minutes. If you are using the oven, preheat to 350 degree and roast the broccoli for about 20 minutes or until it starts to char.
For the sauce, combine all the ingredients into a blender or a jar to use the immersion blender. I prefer to use the immersion blender here, but either will work. Start to blend and add a teaspoon of water at a time as needed. This amount will depend on the consistency of the tahini to start. Once it is all blended, the goal is for it to be a similar consistency to ranch dressing.
When broccoli is crispy, pull it out of the air fryer or oven and drizzle with lemon tahini sauce. Serve and enjoy!
Notes
This sauce goes good on ANY veggie so make extra.
I like using avocado oil to get the broccoli crispy, but any oil will do.
If you have smaller kids, you can always cut the broccoli into smaller florets.
