Open the package of ground sausage and crumble it into a large bowl. Add the shredded cheese, Bisquick, seasoned salt and milk to the bowl and use your hands to incorporate all the ingredients together well.
Spray the air fryer basket with olive oil spray.
Using a 1 tablespoon cookie scoop, scoop out individual sausage balls.
Roll them gently to round them out then place them all into the prepared air fryer basket. It is ok if they are touching one another, just do not stack them.
Cook for 10 minutes at 350F degrees (you do not need to preheat the air fryer first).
Remove from the air fryer and enjoy!
Notes
You can switch up the sausage to your favorite flavor. We also really like the spicy sausage.
Water can be used in place of milk.
These can be frozen, see above on how to do that.
The cheese can be switched out, freshly shredded is best.
These can be baked if you don't have an air fryer. See above on how to do that.
