I like to mix it up sometimes and use different minces. Here in Portugal we use a nice blend of pork and beef and it is delicious. Try to avoid turkey though as it can be very dry when cooked in the Air Fryer.
We have found the best place to source ground/minced beef to make Air Fryer Meatloaf Flavoured With Black Peppercorns is from ButcherBox
. You even receive free bacon and $10 off your first order when you sign up with this link.
