I first made these during a holiday gathering and was amazed how quickly they disappeared – everyone kept asking for the recipe. It’s become my go-to for entertaining because it looks impressive but is surprisingly easy to make.

Ingredients

• Two pounds good quality smoked kielbasa: This provides the natural smoky base and should be fairly thick for easy hasselback slicing
• Half a cup Dijon mustard: Gives a sharp, tangy backbone to the glaze and needs to be a good quality brand for best taste
• Quarter cup whole grain mustard: Adds texture with mustard seeds and a milder sweetness enhancing glaze complexity
• Quarter cup packed light brown sugar: For sweetness and caramelization that balances the mustards’ tanginess
• Two tablespoons apple cider vinegar: It brightens and cuts through the richness with fruity acidity
• One tablespoon unsalted butter: Melted helps the glaze stick and gives richness and color during baking
• One teaspoon garlic powder: For mellow garlic undertones
• Half teaspoon onion powder: Adds savory depth and warmth
• Half teaspoon smoked paprika: Optional but highly recommended for smoky color and flavor enhancement
• Quarter teaspoon freshly ground black pepper: Adds subtle heat and aroma
• Pinch of cayenne pepper: Optional for a gentle spicy kick
• Fresh parsley or chives: Finely chopped for a fresh, colorful garnish
• Wooden skewers or toothpicks: Optional for serving but perfect for parties

Step-by-Step Instructions

Preheat Oven and Prep Baking Sheet:

Preheat your oven to 375 degrees Fahrenheit and line a large baking sheet with parchment paper for easy cleanup and to prevent sticking.

Cut Kielbasa into Pieces:

Cut each linked kielbasa into pieces approximately one and a half to two inches long for perfect bite-sized portions that are easy to handle and cook evenly.

Hasselback Slicing Technique:

Place two wooden chopsticks parallel to each other on either side of a kielbasa piece on a cutting board to stop your knife from slicing all the way through. Use a sharp knife to make thin, evenly spaced slices about one eighth of an inch apart, cutting almost through but stopping at the chopsticks. Gently fan out the slices to open the cuts slightly.

Repeat Slicing for All Pieces:

Carefully repeat this technique on every kielbasa piece, ensuring consistent thickness for even cooking and maximum glaze absorption. Arrange the pieces on the prepared baking sheet leaving space between each to avoid steaming.

Make the Mustard Glaze:

In a medium bowl, whisk together Dijon mustard, whole grain mustard, light brown sugar, apple cider vinegar, and melted butter until smooth and the sugar dissolves.

Add Spices to Glaze:

Stir in garlic powder, onion powder, smoked paprika if using, black pepper, and cayenne pepper if desired. Taste and adjust seasoning according to your preference.

First Glaze Application and Bake:

Use a pastry brush to generously coat each hasselback piece with half of the mustard glaze, making sure to get into the cuts. Bake in the preheated oven for 15 minutes to start caramelization and heat through the kielbasa.

Second Glaze Application and Bake:

Remove the baking sheet and brush the remaining glaze over all the pieces, again working it into the crevices. Return to the oven and bake for an additional 15 to 20 minutes until the glaze is glossy and caramelized and the edges are crisp.

Optional Broil for Extra Crispiness:

If you want an even crispier finish, broil for 2 to 3 minutes but watch closely so the glaze doesn’t burn.

Cool and Garnish:

Let the bites cool slightly so the glaze sets then sprinkle with freshly chopped parsley or chives for color and fresh flavor.

Serve with Skewers or Toothpicks:

Arrange neatly on a platter for serving. Insert wooden skewers or toothpicks to make them easy to pick up. Serve warm for best taste.

Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to four days. To reheat gently, warm in a skillet over medium heat or in an oven set to 350 degrees Fahrenheit so the glaze stays sticky and the sausage reheats evenly without drying out. Avoid microwaving if possible as this can make the exterior soggy.

Ingredient Substitutions

If you cannot find kielbasa, a thick smoked sausage like andouille or a good quality smoked bratwurst can work well. For mustard varieties, feel free to mix in spicy brown mustard if you like more heat, or substitute apple cider vinegar with white wine vinegar for a different tang. Brown sugar can be replaced by honey or maple syrup for a slightly different sweetness type and caramelization.

Serving Suggestions

These bites are fantastic with crunchy pickles or a colorful tangy coleslaw to brighten the plate. A creamy honey mustard or a spicy sriracha mayo dipping sauce complements the glaze perfectly. For a more substantial meal, serve alongside roasted vegetables or a simple green salad. They also shine as part of a brunch spread or finger food buffet.

Pro Tips

Make sure your kielbasa is thick enough for hasselback slicing or the pieces may fall apart. Use two chopsticks to avoid slicing all the way through this keeps the sausage intact while allowing glaze absorption. Do not skip brushing on two layers of glaze as this builds flavor and creates that irresistible sticky crust.

Common Recipe Questions

→ What is the hasselback technique?

The hasselback technique involves making thin, closely spaced slices along the beef pieces without cutting all the way through. This allows the glaze to penetrate deeper and creates crispy edges when baked.

→ Can I use other types of sausage instead of beef kielbasa?

Yes, other smoked sausages such as pork kielbasa or smoked bratwurst can work well with this glaze and method, offering slightly different flavor profiles.

→ How do I prevent the slices from cutting all the way through?

Placing two wooden chopsticks or spoons on either side of the beef piece as a guide helps prevent cutting completely through, ensuring the slices fan out nicely.

→ What does the mustard glaze consist of?

The glaze combines Dijon and whole grain mustard, brown sugar for sweetness, apple cider vinegar for brightness, melted butter for richness, and spices like garlic powder, smoked paprika, and black pepper for depth.

→ How can I achieve the perfect caramelization on these bites?

Brushing the glaze twice during baking allows it to thicken and caramelize, and finishing under the broiler for a few minutes provides an extra crispy, golden finish—just watch carefully to avoid burning.

→ What serving suggestions complement these mustard beef bites?

They pair wonderfully with pickles, coleslaw, or creamy dips like honey mustard or sour cream with chives. Wooden skewers make them easy to serve at parties and gatherings.
