Savory Mustard Hasselback Kielbasa Bites are a fun and tasty twist on classic kielbasa sausage. These little bites are sliced just right to hold pockets of mustard that bake into the meat, making every bite flavorful and juicy. The crisp edges and tender middle create a delightful mix of textures that keep everyone coming back for more.
I love making these for casual get-togethers because they’re so easy to prepare but look fancy enough to impress. I usually use a sharp or Dijon mustard, but you can try sweet mustard too if you want a milder flavor. A quick tip: make sure to slice the kielbasa all the way through just a bit before baking so the mustard settles nicely inside each cut.
These bites are perfect served warm with a side of crunchy veggies or your favorite dipping sauce. Whenever I bring them out, they disappear fast, and people often ask for the recipe. They also pair great with a cold beer or a simple salad, making them a versatile and crowd-pleasing snack for any occasion.
Key Ingredients & Substitutions
Kielbasa: This smoked sausage is the star of the dish. It has a rich, garlicky flavor that holds up well to baking. If you can’t find kielbasa, smoked sausage or bratwurst work nicely.
Mustard: Dijon mustard adds a nice tang and slight heat. You can swap it with whole grain or spicy brown mustard for different textures and flavors.
Bacon: Bacon brings crispiness and smoky goodness that wraps the bites. Turkey bacon can be a leaner alternative but might be less crispy.
Spices: Garlic powder and smoked paprika boost flavor without overpowering. Feel free to adjust the amounts to match your taste.
How Do You Perfectly Hasselback the Kielbasa Without Cutting Through?
The slicing technique is key! You want thin, even cuts without cutting all the way through so the sausage holds its shape and the mustard fills the slits.
- Use a sharp knife for better control and clean cuts.
- Place the sausage between two chopsticks or wooden spoons to act as cutting guides. This stops the knife from slicing all the way through.
- Make about 5-6 thin cuts per piece, spaced evenly.
- Spread mustard into the cuts gently so the slices stay intact.
With practice, this technique helps the flavors meld inside while keeping the bites juicy and perfect for wrapping with bacon!

Equipment You’ll Need
- Baking sheet – I prefer this for even heat and easy cleanup when roasting the bites.
- Sharp knife – makes clean, thin slices without squishing the sausage.
- Toothpicks – help secure the bacon wrapped around each bite so it stays intact during baking.
- Brush or small spoon – to spread or brush mustard into the cuts neatly.
- Cutting board – provides a stable surface for slicing safely.
Flavor Variations & Add-Ins
- Cheese: Add a little shredded cheese like cheddar or Swiss into the cuts for extra gooeyness.
- Spices: Mix in some cayenne pepper or chili powder to give it a spicy kick.
- Veggies: Insert small pieces of pickles, jalapeños, or caramelized onions into the slices for added flavor.
- Sweet & Savory: Brush the bacon with maple syrup before baking for a sweet contrast to the smoky sausage.
Savory Mustard Hasselback Kielbasa Bites
Ingredients You’ll Need:
Main Ingredients:
- 3 large kielbasa sausages
- 3 tablespoons Dijon mustard (or your favorite savory mustard)
- 12 slices of bacon (enough to wrap each bite)
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- Salt and freshly ground black pepper, to taste
For Garnish and Serving:
- Fresh parsley, chopped
- Optional dipping sauce: extra mustard or honey mustard
Time Needed:
This recipe takes about 10 minutes to prepare and 25-30 minutes to bake. In around 40 minutes, you’ll have warm, crispy, and flavorful bites ready to enjoy.
Step-by-Step Instructions:
1. Preheat the Oven:
Set your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil to make clean-up simple.
2. Prepare the Kielbasa:
Slice each kielbasa sausage into bite-sized pieces, about 2 inches long.
3. Create Hasselback Cuts:
For each piece, make 5-6 thin, parallel cuts without slicing all the way through. The pieces should hold together at the bottom, similar to making Hasselback potatoes.
4. Add Mustard and Seasonings:
Use a small brush or spoon to carefully spread about 1 teaspoon of Dijon mustard into the cuts on each piece. Then sprinkle garlic powder, smoked paprika, salt, and pepper on top for extra flavor.
5. Wrap with Bacon:
Wrap each mustard-filled piece tightly with a slice of bacon. Secure with toothpicks if needed to keep the bacon in place.
6. Bake the Bites:
Place the wrapped bites on the baking sheet with the cut side facing up. Bake for 25-30 minutes, turning the bites halfway through to crisp the bacon evenly and heat the kielbasa all the way through.
7. Finish and Serve:
Once baked, remove the bites from the oven and let them cool slightly. Garnish with freshly chopped parsley for a fresh touch. Serve warm with your choice of dipping sauce, like extra mustard or honey mustard.
Can I Use Frozen Kielbasa for This Recipe?
Yes, but be sure to fully thaw the kielbasa in the refrigerator overnight before slicing and preparing. This ensures even cooking and easier slicing for the Hasselback cuts.
Can I Prepare These Bites Ahead of Time?
Absolutely! You can assemble the mustard-filled, bacon-wrapped bites and refrigerate them for up to 24 hours before baking. Just bake them fresh when ready for the best crispy texture.
How Should I Store Leftovers?
Store any uneaten 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 restore the crispiness.
What Can I Serve with These Kielbasa Bites?
They’re great with mustard-based dipping sauces, honey mustard, or even a side of pickled veggies for contrast. A cold beer or simple salad pairs wonderfully as well.
