Begin by preheating your oven to 400°F (200°C). While the oven heats, grab a baking dish and coat it thoroughly with nonstick spray to prevent any sticking.

Next, take the kielbasa sausage and slice it crosswise into thin pieces, about 1/4 inch apart, ensuring you don’t cut all the way through.

In a small mixing bowl, combine the yellow mustard, honey, and paprika, stirring until the mixture is smooth and well-blended.

Using a pastry brush or your fingers, generously coat each sliced kielbasa piece with the mustard glaze.

Carefully place the glazed kielbasa in the prepared baking dish, arranging them in a single layer. Bake for 20-25 minutes until golden brown.

Once baked, remove your Mustard Hasselback Kielbasa Bites from the oven and garnish them with chopped fresh parsley.
