Ingredients for Hasselback Kielbasa Bites with Tangy Mustard

Main Ingredients

500 g smoked kielbasa sausage, cut into 4–5 cm bite-size pieces
200 g streaky bacon, cut into halves
15 ml olive oil

Mustard Sauce

60 g Dijon mustard
30 g whole-grain mustard
25 ml honey
15 ml apple cider vinegar
60 ml heavy cream (optional, for a rounder finish)

1 g smoked paprika
1 g garlic powder
Freshly ground black pepper, to taste

Fresh chives or parsley, finely chopped, for garnish

Step-by-Step Instructions – How to Make Hasselback Kielbasa Bites with Tangy Mustard

Prepare the kielbasa
First, preheat the oven to 200°C. Place each kielbasa piece between two chopsticks or wooden skewers and make shallow slices across the top, creating a hasselback effect without cutting through. This technique increases surface area and improves flavor absorption.
Wrap with bacon
Next, wrap each sliced kielbasa piece with a strip of bacon, tucking the end underneath. Arrange the bites on a parchment-lined baking tray, spacing them evenly.
Initial roasting
Lightly brush the bites with olive oil. Then roast for 15 minutes, allowing the bacon to begin rendering and crisping while the sausage warms through.
Prepare the mustard glaze
Meanwhile, whisk Dijon mustard, whole-grain mustard, honey, apple cider vinegar, smoked paprika, garlic powder, and black pepper in a small saucepan. Heat gently over low heat, stirring until smooth and aromatic. Additionally, add cream if using for a silkier texture.
Glaze and continue cooking
Remove the tray from the oven and spoon the mustard sauce generously over each bite, ensuring it seeps into the cuts. Return to the oven and roast for another 15–20 minutes until the bacon is deeply golden and the sauce caramelizes.
Final finish
Finally, let the bites rest for 5 minutes. Garnish with chopped herbs and serve warm with extra mustard sauce on the side.

Variations of Hasselback Kielbasa Bites with Tangy Mustard

With meat: Substitute kielbasa with smoked beef sausage or merguez for a stronger, spiced profile.

Vegetarian version: Use plant-based smoked sausage and vegan bacon; the mustard glaze remains unchanged.

Creamier version: Increase cream to 100 ml and finish with a knob of butter for extra richness.

Spicier version: Add 2 g cayenne pepper or a spoon of spicy brown mustard to the sauce.

Seasonal swap: In autumn, add a splash of apple juice or cider; in summer, finish with fresh thyme and lemon zest.

Tips for Perfect Results – Hasselback Kielbasa Bites with Tangy Mustard

Precision cutting: Use chopsticks to prevent slicing all the way through the sausage.

Balanced seasoning: Taste the sauce before glazing; adjust sweetness or acidity as needed.

Crisp control: If bacon browns too quickly, loosely cover with foil and continue roasting.

Storage: Refrigerate leftovers up to 3 days; reheat gently at 170°C to preserve texture.

Avoid overcrowding: Space bites well so bacon crisps evenly rather than steaming.
