Peel 6-8 potatoes and slice into 1/4” round slices, cover with water in pot and bring to boil, allow to boil for 2-3 minutes.
In greased Pyrex build layers. Starting by using a slotted spoon to remove potatoes from water. You will want some of the water from the boiling process to make it into the Pyrex, but not an excessive amount. Using a slotted spoon but not shaking the potatoes dry works perfectly. Once you have a base layer of potatoes, add a layer of sliced onion (approx. ½ of a medium yellow onion), salt, pepper, Pit Boss Bacon Cheddar Burger Seasoning, a drizzle of sweet condensed milk, half a stick of butter cut into pats, and a layer of sliced smoked gouda cheese. Repeat on the 2nd layer. Top with grated cheddar jack or Colby jack cheese.
Cook at 325-350 for approx. 1 hour or until the potatoes are tender.
