What You’ll Need

Here’s what you’ll need to make your Crockpot Pierogi Casserole come together smoothly. Trust me, this ingredient list keeps things simple without sacrificing flavor!
- 1 (16-ounce) package frozen pierogies (potato and cheese work perfectly)
- 1 pound smoked kielbasa, sliced into rounds
- 1 medium onion, thinly sliced
- 2 cups shredded cheddar cheese
- 1 cup sour cream
- 1 (10.5-ounce) can cream of mushroom soup
- 2 tablespoons butter, melted
- Salt and pepper to taste
- Fresh parsley (optional, for garnish)
For the best Crockpot Pierogi Casserole, I recommend buying quality smoked kielbasa – it really boosts the flavor without adding extra work. You’ll find everything for this Crockpot Pierogi Casserole at your regular grocery store’s freezer and deli sections. If you can, get fresh onions instead of pre-chopped—they add a fresher taste here.
This Crockpot Pierogi Casserole is forgiving if you need to swap out ingredients. Don’t have kielbasa? Try smoked sausage or even cooked ground beef. Instead of cream of mushroom soup, cream of chicken or celery works well too. My family prefers when I use sharp cheddar cheese because it adds a nice tang, but mild cheddar will keep the flavors mellow.
Before cooking, thaw the pierogies for a bit so they don’t stick together in the crockpot. Also, give your kielbasa and onion slices a quick sauté to bring out their best flavors — it’s a little extra step that pays off. Here’s a Crockpot Pierogi Casserole secret that makes all the difference: coat the slow cooker insert with butter before layering to prevent sticking and help everything brown evenly.
How to Make It
Making this Crockpot Pierogi Casserole is easier than it seems, and with a few steps, you’ll have a dinner everyone looks forward to. This crockpot comfort food usually takes about 3 to 4 hours on high, or 6 to 7 hours on low.
- Start by lightly buttering the inside of your slow cooker. This prevents the cheesy pierogi bake from sticking as it cooks.
- Layer half the pierogies in the bottom of the crockpot. Spread half the sliced onions and kielbasa over them.
- In a medium bowl, mix the sour cream and cream of mushroom soup, then spoon half of this sauce over the pierogies and meat layer.
- Sprinkle one cup of shredded cheddar cheese on top.
- Repeat those layers with the remaining pierogies, onions, kielbasa, sauce mixture, and finish with the last cup of cheese.
- Spread the melted butter evenly over the top—this helps create those golden, crusty bits everyone loves.
- Cover the casserole with the crockpot lid and cook on high for 3-4 hours. You’ll know your Crockpot Pierogi Casserole is ready when the cheese is bubbly and golden, and the pierogies are tender.
Your kitchen will smell amazing while this Crockpot Pierogi Casserole cooks, filling the house with that cozy, cheesy aroma. Don’t worry if your Crockpot Pierogi Casserole looks a little liquidy at first—that sauce thickens as it cooks, turning everything creamy and delicious.
Here’s where I used to mess up my Crockpot Pierogi Casserole: watching the time too closely. I learned it’s better to go by how the cheese looks and the tenderness of the pierogies rather than just the clock. While your Crockpot Pierogi Casserole is cooking, you’ll have time to prep a green salad or check homework without rushing dinner.
If you want to try something slightly different, adding sautéed mushrooms or swapping kielbasa for ground beef gives you a fresh take. Check out this Crock Pot Pierogi and Kielbasa Casserole – The Country Cook for a similar recipe with a tasty twist.
