These Savory Mustard Hasselback Kielbasa Bites are little flavor-packed treats that combine juicy kielbasa sausage with a tangy mustard glaze. The kielbasa is sliced thinly but not all the way through, creating cute, fan-like slices that soak up all the tasty mustard goodness while getting crisp edges. They’re simple to make but look impressive and invite everyone to grab a handful.
I love making these for casual get-togethers because they’re easy to pop in the oven and don’t need much fuss. The mustard adds just the right amount of zing without being overpowering, and the way the sausage crisps up around the edges always makes me smile. I usually serve them with a little toothpick for easy snacking, which is perfect for busy hands and hungry guests.
These bites always remind me of fun family nights or game days where people are chatting and nibbling without needing a full meal. They’re one of those recipes that gets passed around quickly because they’re so good and so simple. If you want to impress without spending hours in the kitchen, these kielbasa bites are a perfect go-to.
Key Ingredients & Substitutions
Kielbasa: This smoked sausage is the star, giving a rich, meaty flavor. If you can’t find kielbasa, smoked Polish sausage or even smoked bratwurst are good alternatives.
Mustard: Dijon and whole grain mustards add tang and texture. You can swap Dijon for yellow mustard or spicy brown mustard based on your taste.
Spices: Garlic powder and smoked paprika add warmth and depth. You can use regular paprika or add a pinch of cayenne for a little heat.
Olive Oil: Helps the glaze stick and crisps up the sausage edges. You can use any mild oil like avocado or vegetable oil if you prefer.
How Do You Make the Hasselback Slices Without Cutting All the Way Through?
Getting those perfect thin slices that fan out needs a steady hand and a sharp knife.
- Place each kielbasa piece on a cutting board.
- Use chopsticks or wooden spoons on either side of the sausage as a cutting guide. They stop the knife from slicing all the way through.
- Make thin cuts, about 1/8 inch apart, down almost to but not through the bottom.
- This lets the mustard glaze soak in and the edges crisp well while keeping each piece intact for easy handling.
Equipment You’ll Need
- Baking sheet – I recommend using one with a rim to catch any drips, and it’s easy to clean afterward.
- Sharp knife – crucial for making precise Hasselback cuts without cutting all the way through.
- Small spoon or pastry brush – helps spread or drizzle the mustard mixture evenly over the sausages.
- Cutting board – provides a stable surface for slicing the kielbasa safely.
- Toothpicks – handy for serving and making each bite easier to pick up and eat.
Flavor Variations & Add-Ins
- Swap the mustard for honey mustard or spicy brown mustard for different flavor profiles that suit your taste.
- Add a sprinkle of shredded cheese like cheddar or Parmesan on top during the last few minutes of baking for a cheesy crunch.
- Mix in chopped herbs such as thyme or rosemary to the mustard glaze for an herbal twist.
- Wrap each sausage piece in bacon before slicing for extra richness and smoky flavor.

How Much Time Will You Need?
This recipe takes about 10 minutes to prep and about 20-25 minutes to bake, making it an easy and quick appetizer for your next gathering or snack time.
Step-by-Step Instructions:
1. Prepare Your Oven and Baking Sheet:
Start by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper or give it a light coating of oil to prevent sticking.
2. Slice the Kielbasa:
Cut each kielbasa link crosswise into bite-sized pieces, about 1 to 1.5 inches thick. These pieces will be easy to handle and perfect for snacking.
3. Make Hasselback Cuts:
Using a sharp knife, carefully make thin, parallel slices across each kielbasa piece, about 1/8 inch apart. Cut almost all the way through, but leave the bottom intact so the slices stay fanned out and connected.
4. Mix the Mustard Glaze:
In a small bowl, whisk together the Dijon mustard, whole grain mustard, olive oil, garlic powder, smoked paprika, salt, and black pepper until smooth and combined.
5. Apply the Glaze and Bake:
Place the kielbasa pieces on your baking sheet. Using a small spoon or pastry brush, gently spread or drizzle the mustard mixture over each piece, making sure some seeps between the slices for great flavor.
Bake in the preheated oven for 20-25 minutes, until the edges are crisp and caramelized, and the mustard glaze is bubbling.
6. Finish and Serve:
Take the kielbasa bites out of the oven and allow them to cool for a few minutes. Transfer them to a serving platter, drizzle any remaining mustard glaze on top, and garnish with fresh microgreens or parsley if you like.
Insert toothpicks into each bite—for easy grabbing and sharing—and serve warm.
Can I Use Frozen Kielbasa for This Recipe?
Yes, but make sure to thaw it completely in the refrigerator overnight before slicing and preparing. This helps ensure even cooking and easy slicing for the Hasselback cuts.
How Can I Make This Recipe Spicier?
To add some heat, try mixing a pinch of cayenne pepper or chili flakes into the mustard glaze, or swap regular smoked paprika for a spicy smoked variety.
Can I Prepare the Kielbasa Bites Ahead of Time?
Absolutely! You can slice the kielbasa and mix the mustard glaze ahead, then keep them covered in the fridge for up to 24 hours. Just assemble and bake when ready to serve.
What’s the Best Way to Store Leftovers?
Store any uneaten kielbasa bites in an airtight container in the refrigerator for up to 3 days. Reheat them in the oven at 350°F (175°C) for about 10 minutes to keep them crispy.
