Print Recipe

A quick and easy grilled kielbasa recipe featuring smoky sausage, sweet caramelized onions, and tangy whole grain mustard. Perfect for casual gatherings and busy weeknights.

Ingredients

Scale
  • 1 pound (450g) smoked kielbasa, sliced into 1/2-inch thick rounds
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons extra-virgin olive oil
  • 1 tablespoon butter
  • 3 tablespoons whole grain mustard
  • Freshly ground black pepper, to taste
  • Pinch of salt
  • Fresh parsley, finely chopped (optional)

Instructions

  1. Heat 2 tablespoons of olive oil over medium-low heat in a large skillet. Add the thinly sliced yellow onions and a pinch of salt. Stir occasionally and cook slowly until onions are deeply caramelized, about 15-20 minutes.
  2. Stir in 1 tablespoon of butter into the caramelized onions. Set aside and keep warm.
  3. Slice the kielbasa into 1/2-inch rounds, keeping slices uniform.
  4. Preheat grill or grill pan to medium-high heat.
  5. Place kielbasa slices on the grill and cook undisturbed for 3-4 minutes per side until golden with grill marks and heated through, about 6-8 minutes total.
  6. Sprinkle grilled kielbasa with freshly ground black pepper.
  7. Serve kielbasa topped with caramelized onions and spoon whole grain mustard alongside or on top.
  8. Garnish with chopped fresh parsley if desired.

Notes

Do not pierce the sausage while grilling to keep juices inside. Caramelize onions low and slow to avoid bitterness. Add a splash of water if onions start to stick or dry out. Use tongs to turn kielbasa. Leftover kielbasa can be refrigerated for up to 3 days or frozen for 2 months (without onions).
