Place all the ingredients for the mango BBQ sauce in a blender and process until smooth. If it is too thick, simply add a tablespoon of water until you reach your desired consistency.
Set a saucepan on medium heat and add the sauce. Bring to a very light simmer, then add the arrowroot slushy mix. Stir immediately to prevent clumping and remove from the heat. Continue stirring to thicken the sauce.
Note: if it is too thick add a tablespoon of water. If it is too thin, add 1/2 tablespoon of arrowroot mixed with 1 tablespoon of water and add to the sauce – make sure the sauce is still hot to activate the arrowroot.
Set aside to cool and thicken.
Add chicken thighs to a bowl and lightly spray with oil, add the seasonings, and rub all over the chicken. Let it marinate at room temperature for 10 – 15 minutes (or overnight) for best results.
Set air-fryer to 410F.
If you do not have an air-fryer, you can use an oven. Set temp to 420F.
Place chicken in an air-fryer basket, top side down, and lightly spray with avocado oil (or another high smoke point oil). Air-fry for 8 – 10 minutes depending on the size of the basket and how many thighs can fit.
Baste the bottom side with a little BBQ mango sauce, then flip the chicken thighs over and baste with the sauce. Place back in the air-fryer for 6 – 8 minutes (depending on the size and quantity of chicken thighs).
Remove and set aside to cool.
Repeat with any remaining chicken.
Enjoy as an entree to your meal prep or weeknight dinner!
The chicken will last 4 – 6 days in the fridge in an air-tight container. Reserve in a separate airtight container any remaining sauce to use for another recipe.
