This burger combines a ground pork and chopped kielbasa patty with slowly cooked sauerkraut, Swiss cheese, and whole grain mustard on a brioche bun. It takes about 45 minutes start to finish and makes a genuinely different cookout burger that holds up well when you’re feeding a group. The patty does the heavy lifting — kielbasa folded into ground pork means every bite has that smoky, garlicky flavor without any extra sauce work.
Why this recipe works
Two things make this burger succeed where similar ideas fall flat. First, finely chopping the kielbasa before mixing it into the ground pork distributes the fat and seasoning evenly through every patty — you get consistent flavor in every bite rather than a chunk of sausage sitting next to plain meat. Second, cooking the sauerkraut low and slow with butter, onions, and toasted caraway before it ever touches the burger transforms it from a sharp, wet condiment into a concentrated, slightly caramelized topping that won’t soak through the bun or slide off the patty. Skip the egg in the mix — it makes the patty mushy and the kielbasa fat already provides enough binding. These two steps are what separate a burger that tastes intentional from one that just tastes busy.
Common problems and fixes
- Patties fall apart on the grill: The kielbasa adds moisture, which can loosen the mix if it warms up too much before cooking. Form your patties cold and refrigerate them for at least 20 minutes before they hit the grate. This is especially important when you’re cooking a large batch — pull them from the fridge in shifts rather than all at once.
- Sauerkraut is watery and makes the bun soggy: Drain the sauerkraut thoroughly and press it dry with paper towels before it goes into the pan. If you’re making a big batch of the topping ahead of time, cook off any remaining liquid over medium-high heat for the last two minutes.
- Cheese slides off before it melts: Add the Swiss slice when the patty is about 90 seconds from done, then tent the pan or close the grill lid. The trapped steam melts it fast and keeps it anchored to the meat rather than pooling on the grate.
- Patties puff up in the center during cooking: Press a shallow thumbprint into the center of each raw patty before cooking. Ground pork shrinks more than beef as it cooks, and without the indent the middle domes up and the burger rocks on the bun.
- Flavor tastes flat when scaled up: Kielbasa brands vary a lot in salt and smoke level. If you’re doubling or tripling the recipe, taste a small cooked piece of the raw patty mix before forming all the patties — pan-fry a marble-sized ball for 90 seconds. Adjust smoked paprika or Dijon at that point rather than after everything is formed.
Polish Kielbasa and Sauerkraut Burger
Ingredients
For the Burger Patties:
- 4 links Polish kielbasa sausage preferably smoked with garlic and marjoram
- 1 lb ground pork 85/15 ratio for flavor and juiciness
- 1 tbsp Dijon mustard
- 1 tsp smoked paprika
For the Sauerkraut Topping:
- 1 tbsp unsalted butter
- 1 small yellow onion thinly sliced
- 2 cups sauerkraut drained and rinsed
- 1 tsp caraway seeds lightly toasted for extra flavor
- 4 pieces brioche buns toasted
- 4 slices Swiss cheese
- ¼ cup whole grain mustard for spreading on buns
Instructions
- Chop each kielbasa link finely and mix with ground pork, Dijon mustard, and smoked paprika until just combined. Do not overmix to preserve texture.
- Form the mixture into four patties, slightly wider than your buns to account for shrinkage. Cover and refrigerate for at least 10 minutes.
- While the patties set, melt butter in a skillet over medium heat (about 350°F / 175°C). Add the sliced onion and cook until soft and golden, about 5–6 minutes.
- Add drained sauerkraut and caraway seeds to the onions. Cook together for 5–7 more minutes, stirring often until slightly caramelized and warming aromatic notes arise.
- Heat a cast-iron skillet or griddle over medium-high heat (about 400°F / 200°C). Lightly oil the surface, then sear patties for about 4 minutes on each side, flipping once, or until internal temperature reaches 160°F (71°C).
- In the last minute of cooking, place a slice of Swiss cheese on each patty to melt.
- Toast brioche buns cut-side down on the skillet for 1–2 minutes until golden.
- Spread whole grain mustard on both bun halves, layer with the cheesy patty, top generously with sauerkraut-onion mixture, then crown with the bun top. Serve immediately.
Notes
- For a smokier flavor, grill the patties over charcoal instead of a skillet.
- Swap Swiss cheese for sharp cheddar or Gruyère for bolder taste.
- Vegetarian Twist: use Beyond Sausage with tempeh sauerkraut topping.

Frequently asked questions
What internal temperature does this patty need to reach?
Cook to 160°F (71°C) internal — no exceptions. This is a ground pork and kielbasa blend, and unlike whole-muscle beef it must be cooked through completely; a meat thermometer is the only reliable way to confirm it.
Can I make the patties the night before a cookout?
Yes, and it actually helps. Form the patties, layer them between parchment, cover tightly, and refrigerate overnight. Cold patties hold their shape better on a hot grill, which matters when you’re cooking 12 at once instead of four.
Can I cook these on a gas grill instead of a skillet?
Absolutely — medium-high direct heat works well. Oil the grates well before cooking because the kielbasa fat can cause sticking, and keep a lid nearby so you can tent the patties for the cheese-melting step.
What’s the best way to keep the sauerkraut topping warm for a crowd?
Transfer the finished sauerkraut to a small slow cooker on the warm setting or a covered saucepan over the lowest burner. It holds well for up to two hours without drying out, and guests can spoon it on themselves.
Can I substitute a different cheese if I can’t find Swiss?
Gruyère is the closest match and melts cleanly. Sharp cheddar works too but adds more sharpness that can compete with the sauerkraut — if you go that route, use a thinner slice.
Is there a make-ahead option for the full burger assembly?
Keep components separate until serving — assembled burgers go soggy fast, especially with sauerkraut involved. Pre-cook the sauerkraut topping up to two days ahead and refrigerate it; reheat in a pan while the patties cook.
