Slice the Kielbasa: Carefully slice the kielbasa into ¼-inch thick slices, going about ⅔ of the way down. Use chopsticks or a wooden spoon to guide your cutting and prevent slicing all the way through.

Cut into Bites: Next, chop the kielbasa crosswise into 1-inch pieces, yielding approximately 20 bites per ring. Gather all these delicious morsels in a large bowl, ready for flavoring.

Mix the Sauce: In a small mixing bowl, combine the barbecue sauce, Dijon mustard, and maple syrup. Stir until everything is well blended and harmonious.

Coat the Kielbasa: Pour about ½ cup of your sauce over the kielbasa bites, tossing gently to ensure every piece is coated. Reserve the remaining sauce for a delightful drizzle post-cooking.

Arrange for Air Frying: Lay the kielbasa bites in a single layer in your air fryer's basket. If batch cooking, keep bites arranged without overlapping.

Air Fry the Bites: Set your air fryer to 400°F and cook for 7-9 minutes, until they’re beautifully browned and sizzling.

Add the Finishing Touch: Once cooked, transfer the kielbasa bites to a large platter and drizzle or brush them with about ¼ cup of the reserved maple barbecue sauce.

Garnish and Serve: Finish with a sprinkle of chopped parsley if desired, and serve these warm bites alongside the rest of the maple barbecue sauce for dipping bliss.
