Preheat Oven to 400˚F. Line a large baking sheet with parchment paper, or Silpat.
Cut potatoes into rings no larger than ½" thick. If potatoes are tiny baby red potatoes, you can half or quarter them so they are no larger than ½" thick. Slice Kielbasa into ¾" thick rings. Place potatoes and kielbasa in a large mixing bowl.
Add parsley, 2 pressed garlic cloves, 1 tsp salt, 2 Tbsp olive oil and toss to combine. Spread onto baking sheet and bake at 400˚F for 45-50 min or until potatoes are browned an crisp.* Stir halfway through baking to ensure even browning. Garnish with fresh parsley if desired.
