What is Pierogi Casserole?

Pierogi casserole is exactly what it sounds like: a warm, hearty dish that layers frozen pierogis with creamy sauce, melted cheese, and crispy bacon. Think of it as the laid-back cousin of classic pierogis, no boiling or pan-frying needed. You get all the goodness—chewy dough, cheesy potato filling, rich sauce—without standing at the stove flipping dumplings. Traditionally, pierogis are a Polish favorite, often filled with potatoes, cheese, or sauerkraut. This casserole gives that classic vibe a modern twist by baking everything in one dish. So, if you love pierogis but hate the extra work, this cozy casserole was basically made for you.

Reasons to Try Pierogi Casserole

First, it’s fast—like, real fast. You’re looking at 10 minutes of prep, tops. That makes it perfect for busy weeknights when you’re juggling school drop-offs, work emails, and wondering if laundry actually multiplies. Second, this dish is a serious crowd-pleaser. It’s cheesy. It’s creamy. It has bacon. Need we say more? Even the picky eaters at your table won’t put up a fight. Plus, it’s super customizable—swap in turkey bacon, add sautéed mushrooms, or toss in some spinach if you’re feeling fancy. And here’s the kicker: pierogi casserole uses mostly pantry and freezer staples, so it’s a brilliant “what’s for dinner” backup plan.

Ingredients Needed to Make Pierogi Casserole

• 2 tablespoons olive oil
• ½ onion, chopped
• 2 cloves garlic, minced
• 1 can (10.5 oz) cream of mushroom soup
• ½ cup sour cream
• ¼ cup milk
• 1 cup shredded cheddar cheese
• ½ cup bacon, cooked and crumbled
• 1 package (16 oz) frozen pierogis, thawed
• 3 tablespoons fresh chives, minced
• Nonstick cooking spray

Instructions to Make Pierogi Casserole

You don’t need to be a kitchen wizard for this one. Just grab a baking dish, a skillet, and your favorite spatula. Dinner is just a few steps away.

Preheat and Prep

Preheat your oven to 375°F. Spray a 9×9 baking dish with nonstick cooking spray and set it aside. That’s your cheesy playground.

Sauté the Onion and Garlic

Heat olive oil in a large skillet over medium-high heat. Add the chopped onion and minced garlic. Sauté for about 7 to 8 minutes until everything is soft and fragrant—basically until your kitchen smells amazing.

Make the Sauce

Remove the skillet from the heat and stir in the cream of mushroom soup, sour cream, milk, shredded cheddar cheese, and crumbled bacon. Stir until it’s a cheesy, creamy dream.

Layer and Load the Casserole

Scoop half of the cheese mixture into your baking dish and spread it out. Arrange the thawed pierogis on top in a single layer (it’s okay if they overlap a bit—think cozy, not perfect). Spoon the rest of the cheese mixture over the pierogis, making sure they’re all coated in sauce.

Bake to Golden Perfection

Sprinkle the chopped chives over the top. Bake for 30 to 40 minutes, until the top is golden brown and the sauce is bubbling. Let it cool for 5 minutes before diving in—hardest part, we know.

What to Serve with Pierogi Casserole

Pierogi casserole is rich and hearty, so you’ll want to balance it out with something fresh or crunchy. A crisp green salad with a zippy vinaigrette hits the spot. If you’ve got a little more time, roasted Brussels sprouts or steamed broccoli bring a veggie moment to the table. Feeling extra Midwest? Serve it with applesauce or a side of sauerkraut for that old-school flavor pairing. And if you’re feeding a hungry crowd, a slice of Loaded Baked Potato Casserole makes it a carb lover’s dream team.

Key Tips for Making Pierogi Casserole

Let your frozen pierogis thaw before baking—this helps them heat evenly and soak up all that creamy sauce. Want crispier bacon? Cook it fresh and crumble it right before mixing. If your sauce feels too thick, splash in a little extra milk. Love heat? A pinch of red pepper flakes adds a sneaky kick. And don’t skip the chives—they add a fresh pop that cuts through the richness. Oh, and here’s a bonus tip: double the recipe and bake it in a 9×13 dish if you’re feeding a crowd. It reheats like a champ.

Storage and Reheating Tips for Pierogi Casserole

Leftovers? You’re lucky. Let the casserole cool completely before storing it in an airtight container in the fridge for up to 4 days. To reheat, scoop a portion into a microwave-safe bowl and zap it for 1–2 minutes, stirring halfway. Or pop it back in the oven (covered with foil) at 350°F until heated through. Want to freeze it? Assemble the casserole (but don’t bake it), wrap it tightly with foil, and freeze for up to 2 months. When ready to bake, thaw it overnight in the fridge, then follow the usual baking steps.
