Ingredients
1. Smoked Sausage or Kielbasa
Use 2 pounds fully cooked smoked sausage or kielbasa, sliced into ½-inch rounds.
The sausage provides the savory, smoky backbone of the dish. Because it is already fully cooked, you’re mainly warming it through and allowing its flavorful juices to mingle with the buttery pierogies and onions.
Kielbasa is especially delicious here, but smoked sausage or even a mildly spicy andouille can be used if you want to change things up.
2. Frozen Potato-and-Cheese Pierogies
You’ll need two 16-ounce boxes of frozen potato-and-cheese pierogies.
These are the heart of the recipe. Frozen pierogies make this dish exceptionally convenient because they can be added directly to the slow cooker without boiling or thawing first.
As they cook, the potato-and-cheese filling becomes wonderfully tender while the exterior absorbs the buttery, smoky flavors surrounding it.
3. Yellow Onion
Use 1 large yellow onion, thinly sliced.
The onion adds sweetness and savory depth while cooking underneath everything else. By the time dinner is ready, it becomes soft and tender, making it a perfect partner for the sausage and pierogies.
For a sweeter flavor, substitute a sweet onion.
4. Unsalted Butter
Use ½ cup, or 1 stick, unsalted butter, melted.
Butter is the simple secret that makes this dish so rich and satisfying. Rather than making a separate sauce, you simply pour the melted butter over the ingredients before cooking.
It coats the pierogies, sausage, and onions and creates a luscious, savory finish.
How to Make Slow Cooker Sausage and Pierogies
Step 1: Prepare the Slow Cooker
Lightly grease the inside of a 5- to 6-quart slow cooker with a little butter or nonstick cooking spray.
This helps reduce sticking and makes serving and cleanup easier.
Step 2: Add the Onion
Spread the sliced onion evenly across the bottom of the slow cooker.
The onion creates a flavorful base for the dish and helps keep the pierogies from sitting directly against the bottom.
Step 3: Add the Frozen Pierogies
Place the frozen potato-and-cheese pierogies over the onions.
Arrange them as evenly as possible. A little overlap is fine, but try not to compress them into one tightly packed mass.
Do not thaw the pierogies first. They can go directly from the freezer into the slow cooker.
Step 4: Add the Sausage
Scatter the sliced smoked sausage evenly over the pierogies.
Spreading the sausage throughout the slow cooker helps ensure that every serving gets a delicious combination of sausage, pierogies, and onions.
Step 5: Pour Over the Butter
Slowly drizzle the melted butter over the sausage and pierogies.
Try to distribute it across the entire surface so the butter can work its way down through the layers as everything cooks.
Step 6: Slow Cook
Cover and cook on LOW for 3 to 4 hours, or until the pierogies are tender, the onions are soft, and the sausage is heated through.
For the best texture, avoid repeatedly opening the lid while the dish cooks. Every time you lift the lid, heat escapes and cooking time can increase.
Step 7: Gently Stir
Once everything is cooked, use a large spoon or spatula to gently fold the ingredients together.
Start from the bottom and carefully bring the onions and buttery juices upward without breaking apart the tender pierogies.
Taste and add salt and freshly ground black pepper if needed.
Step 8: Serve Hot
Spoon the sausage and pierogies into warm bowls, making sure each serving includes plenty of smoky sausage, tender pierogies, sweet onions, and buttery sauce.
Then watch how quickly that bowl disappears.
Pro Tips for Perfect Pierogies
Don’t thaw the pierogies
One of the biggest conveniences of this recipe is that the pierogies can be used straight from the freezer. Thawing them first can make them softer and more prone to breaking.
Keep the slow cooker covered
Try not to remove the lid during the early cooking period. Maintaining consistent heat helps the frozen pierogies cook evenly.
Don’t over-stir
Pierogies become delicate as they cook. Instead of vigorously stirring the finished dish, gently fold everything together.
Slice the sausage evenly
Cut the sausage into roughly ½-inch rounds so the pieces heat evenly and are easy to scoop with the pierogies.
Season at the end
Smoked sausage and pierogies can already contain quite a bit of seasoning, so taste the finished dish before adding salt.
Use LOW for the best texture
The LOW setting gives the onions time to soften and allows the pierogies to heat gradually without becoming overly soft.
Easy Variations
Once you have the basic recipe down, there are several easy ways to customize it.
Add mustard: Stir a spoonful of Dijon or stone-ground mustard into the melted butter before pouring it over the ingredients for a bright, tangy contrast.
Add a little heat: Sprinkle in red pepper flakes or use a spicier smoked sausage.
Lighten the butter: Reduce the butter to 6 tablespoons and add 2 to 3 tablespoons of chicken broth for a slightly lighter, looser sauce.
Try different sausage: Kielbasa, smoked sausage, andouille, or another fully cooked sausage can all work beautifully.
Add fresh herbs: Finish with fresh parsley or chives for a pop of color and freshness.
Swap the onion: Sweet onions are especially good if you prefer a more pronounced sweetness.
What to Serve With Sausage and Pierogies
Because this slow cooker meal is rich and hearty, fresh or crisp sides make a wonderful contrast.
Serve it with:
Simple green salad
Steamed green beans
Roasted broccoli
Tangy sauerkraut
Fresh parsley or chives
Grainy mustard
Sour cream
Crusty bread
A spoonful of sauerkraut or mustard is particularly delicious alongside the smoky sausage because the acidity cuts through the richness of the butter.
How to Store and Reheat Leftovers
Store leftover sausage and pierogies in an airtight container in the refrigerator.
For the best texture, reheat leftovers gently in a covered skillet over low heat. Add a small splash of water or broth if the pierogies seem dry. This helps restore some moisture and keeps the sauce from becoming too thick.
Avoid aggressively stirring the pierogies while reheating because they can break apart once tender.
Frequently Asked Questions
Can I use frozen pierogies in the slow cooker?
Yes. Frozen potato-and-cheese pierogies can be added directly to the slow cooker. There is no need to thaw them beforehand.
Can I use kielbasa instead of smoked sausage?
Absolutely. Kielbasa is an excellent choice and gives the dish a classic smoky, savory flavor.
Can I cook this on HIGH?
LOW is recommended for the most forgiving texture. If using HIGH, keep a close eye on the pierogies because slow cookers vary and they can become overly soft if cooked too long.

Yes. Try reducing the butter to 6 tablespoons and adding a small amount of chicken broth. You can also serve it with plenty of fresh vegetables or a crisp green salad.
What kind of pierogies work best?
Potato-and-cheese frozen pierogies are the classic choice, but you can experiment with other savory frozen pierogi varieties.
