First, drizzle the cauliflower florets with the olive oil and then toss them with the onion powder, garlic powder, smoked paprika, salt, and pepper so that they're well coated in the seasonings.
Next, place them in the air fryer’s basket.
Roast the florets in the Air Fryer at 390°F for around 15 minutes, flipping them every 5 minutes.
Alternatively, you could place the cauliflower on a flat baking sheet and place them in the oven at 425 degrees for around 25 to 30 minutes. You will want to make sure you flip the florets between 12 to 15 minutes into roasting them.
When the cauliflower is done, carefully remove the basket from the air fryer and then serve them on a plate either hot from the oven or cold.
Make Tahini SauceWhile the cauliflower is roasting, add all the tahini sauce ingredients to a food processor and blend until smooth and creamy.
Transfer the tahini to a serving bowl and stir in the chopped fresh parsley. Enjoy!
