How to Cook Kielbasa: 4 Easy Ways (Simmer, Pan-Fry, Grill or Bake)

Simmered, seared, grilled or baked: dinner in about 30 minutes, the way Cleveland has cooked it for generations.

↓ JUMP TO RECIPE

Kielbasa is one of the easiest dinners you can make, and one of the easiest to get wrong. Cook it too hot and the casing splits and the juices end up in the pan instead of in the sausage. Cook it gently and you get a link that snaps when you bite it and stays juicy all the way through.

At Raddell's we've been smoking sausage in Cleveland for generations, and we get asked one question more than any other: "What's the best way to cook it?" Here are the four methods we use at home, with times, temperatures and the little tricks that make a difference.

First: Is Your Kielbasa Already Cooked?

Most kielbasa sold in the U.S., including all of Raddell's smoked sausages, is fully cooked in the smokehouse. You're really just heating it through, which is why it's such a fast weeknight meal. Fresh (raw, unsmoked) kielbasa is different and needs to be cooked all the way through. Either way, heat it until the center reaches 165°F on an instant-read thermometer.

Method 1: Simmer (The Old-World Way, Our Favorite)

This is how Slovenian and Polish families in Cleveland have always done it, and it's the method we recommend on every package. Simmering keeps the sausage plump and juicy because it never gets hot enough to burst.

• Place the links in a pot and cover with cold water.
• Bring to a boil, then immediately turn the heat down to a gentle simmer.
• Simmer 30 to 40 minutes for links straight from the refrigerator.

Tip: Never let it keep boiling hard. A rolling boil is what splits casings.

Method 2: Pan-Fry (Crispy Coins in 10 Minutes)

Best when you want browned, caramelized edges for pierogi, eggs, pasta or a skillet with peppers and onions.

• Slice the kielbasa into 1/2-inch coins (cut on a slight angle for more browned surface).
• Heat 1 tablespoon of butter or oil in a skillet over medium heat.
• Add the coins in a single layer and cook 3 to 4 minutes per side until deep golden brown.

Method 3: Grill (Simmer First, Then Grill)

Grilling over high heat can dry out a smoked sausage. Our trick: simmer the links for about 10 minutes first, then move them to a medium-hot grill for 4 to 6 minutes, turning often, just until you get grill marks. You get the smoky char without a split, dried-out link. Serve on a bun with Bertman Ball Park Mustard for the real Cleveland experience.

Method 4: Bake (Hands-Off Sheet-Pan Dinner)

• Heat the oven to 400°F.
• Slice the kielbasa and toss it on a sheet pan with chunks of potato, onion and peppers, a drizzle of oil and a pinch of Raddell's Garlic Salt.
• Roast the vegetables 15 minutes first, then add the sausage and roast 15 to 20 minutes more, until everything is browned.

What to Serve with Kielbasa

Our customers' favorites: sauerkraut (try our Kielbasa and Sauerkraut Skillet), boiled or mashed potatoes, pierogi, rye bread, horseradish and a good spicy brown mustard. For more ideas, see How to Serve and Enjoy Raddell's Smoked Sausages.

Kielbasa FAQs

How long do you boil kielbasa?

Bring it to a boil, then lower to a gentle simmer for 30 to 40 minutes for whole refrigerated links. Avoid a hard boil, which can split the casing.

Do you have to cook kielbasa?

Smoked kielbasa like Raddell's is fully cooked, but it tastes best (and is safest) heated to 165°F. Fresh kielbasa must always be cooked through.

What is the best way to cook kielbasa?

For juicy, old-world flavor, simmer it. For crispy edges, slice and pan-fry. For a cookout, simmer first and finish on the grill.

Can you freeze kielbasa?

Yes. Freeze it in its vacuum-sealed package for the best quality within 1 to 2 months, then thaw it in the refrigerator overnight.
