🛒 Ingredients You’ll Need
Simple, affordable, and easy to find — here’s what goes into your creamy pierogi bake:
For the Casserole:
- 24 oz frozen potato & cheese pierogies – the fluffy base of this dish.
- 1 lb smoked kielbasa (Polish sausage) – adds smoky, savory depth.
- 1 can (10.5 oz) condensed cream of mushroom soup – the secret to that silky, rich sauce.
- ½ cup sour cream – adds tang and smoothness.
- 2 cups shredded cheddar cheese, divided – melty, golden perfection.
- ½ cup milk (optional) – for a thinner sauce consistency.
- 1 medium onion, thinly sliced – caramelized sweetness balances the saltiness.
- 2 tbsp fresh parsley, chopped (optional) – for freshness and color.
- 1 tbsp olive oil – for sautéing the sausage and onions.
- Salt & black pepper – to season perfectly.
🧂 Tip: Use sharp cheddar for a bolder flavor, or mix cheddar + mozzarella for extra stretch.
👩🍳 Step-by-Step: How to Make Easy Pierogi Sausage Casserole
Step 1: Preheat and Prep
Set your oven to 350°F (175°C) and grease a 9×13-inch casserole dish.
This ensures nothing sticks and cleanup is easy later.
Step 2: Brown the Sausage
Heat olive oil in a skillet over medium heat. Add sliced kielbasa and cook until golden on the edges — about 4–6 minutes.
🔥 Pro Tip: Browning adds smoky flavor and keeps the sausage juicy.
Remove and set aside.
Step 3: Caramelize the Onions
In the same pan, sauté sliced onions for 5–7 minutes until soft and golden.
Add a pinch of salt and pepper to bring out sweetness. Set aside with the sausage.
Step 4: Mix the Creamy Sauce
In a medium bowl, whisk together:
- Cream of mushroom soup
- Sour cream
- Milk (optional)
- A dash of salt and pepper
You’ll get a rich, velvety sauce that ties everything together.
Step 5: Layer It All
In your casserole dish:
- Arrange half the frozen pierogies.
- Add half the sausage and onions.
- Pour half the sauce evenly.
- Sprinkle 1 cup cheese on top.
Repeat the same layering with remaining ingredients, finishing with cheese.
💡 Don’t thaw the pierogies — baking from frozen keeps them tender and not soggy.
Step 6: Bake to Perfection
Cover tightly with foil and bake for 25 minutes.
Remove foil and bake an additional 10–15 minutes until bubbly and golden.
For that irresistible crust, broil for 1–2 minutes — just until the cheese is beautifully browned.
Step 7: Rest, Garnish, and Serve
Let the casserole rest 5 minutes before serving (it thickens slightly as it cools).
Garnish with chopped parsley and serve with a dollop of sour cream or hot sauce for extra flavor.
🌟 Expert Tips for Success
- Brown deeply: Don’t rush the kielbasa — that golden crust = flavor.
- Add a veggie layer: Spinach, mushrooms, or peas make it heartier.
- Make it spicy: Mix in red pepper flakes or use spicy sausage.
- Shortcut hack: Assemble it in the morning, refrigerate, and bake at dinnertime.
- Freeze leftovers: Wrap portions individually — reheats beautifully for busy nights.
