This 3-ingredient slow cooker pierogi feast is the kind of supper I lean on when the garden chores run long and I still want something hot, hearty, and comforting on the table. It starts with good old frozen pierogi, the kind many Midwestern church ladies have sold at fundraisers for decades, and lets them slowly bathe in a lake of buttery onion gravy until they’re tender, golden, and glazed. There’s no browning on the stove, no fancy ingredients—just the same simple trio I watched my mother use on busy planting days. Everything goes into the slow cooker, you walk away for a few hours, and later you lift the lid to find plump, caramelized pockets in a rich, savory, buttery sauce, ready to serve with absolutely zero fuss.
Serve these slow cooker pierogi straight from the crock with plenty of that buttery onion gravy spooned over the top. They’re lovely alongside steamed green beans, a simple cucumber salad, or a bowl of tangy sauerkraut to cut through the richness. If you like, set out a little sour cream or applesauce for dipping, the way many Midwestern tables do with pierogi and potato dumplings. A crisp lager or iced tea pairs nicely, and a slice of rye bread is perfect for mopping up any last bit of that savory glaze.
3-Ingredient Slow Cooker Pierogi FeastServings: 4–6
Ingredients
2 pounds frozen pierogi (any savory flavor, kept frozen)
2 large yellow onions, thinly sliced (about 4 cups)
1 cup (2 sticks) salted butter, cut into chunks
Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with a bit of the butter to keep the pierogi from sticking.
Scatter half of the sliced onions evenly over the bottom of the slow cooker, making a soft bed for the pierogi.
Arrange half of the frozen pierogi in a single, snug layer over the onions. It’s fine if they overlap slightly, but avoid packing them in too tightly so the butter and onions can move around them.
Dot half of the butter chunks over the pierogi, tucking some down between them so it melts and bastes from all sides.
Repeat the layers with the remaining onions, then the remaining frozen pierogi, and finish by dotting the top with the last of the butter.
Cover the slow cooker with the lid and cook on LOW for 3 1/2 to 4 1/2 hours, until the pierogi are tender all the way through and the onions are very soft and deep golden in color.
Once the pierogi are tender, gently stir and turn them with a wide spatula to coat every piece in the buttery onion glaze, being careful not to tear them. If you’d like a richer, more caramelized look, leave the lid off and cook on HIGH for another 15–20 minutes, stirring once or twice, to let some steam escape and thicken the sauce.
Taste a bit of onion and pierogi; if you used unsalted butter, sprinkle lightly with salt to bring out the flavor. Serve the pierogi hot right from the slow cooker, spooning the golden onions and melted butter over the top of each portion.
Variations & Tips
If you grew up in a Midwestern kitchen, you probably have opinions about pierogi fillings. This recipe works with almost any savory frozen pierogi—potato and cheese, potato and onion, sauerkraut, mushroom, or even a hearty meat filling. The richer the filling, the more the buttery onion glaze will cling and shine. For a slightly lighter version, you can cut the butter back to 3/4 cup, though the glaze will be a bit thinner and less glossy. If you only have sweet onions or red onions, you can use them; just note that yellow onions give the most classic, old-fashioned flavor. To stretch the meal for a crowd, layer in an extra pound of frozen pierogi and bump the butter up by 1/4 cup; the onions will still soften and caramelize nicely as long as you don’t overpack the slow cooker. Food safety notes: Keep the pierogi frozen until you’re ready to layer them in the slow cooker; do not thaw on the counter. Always cook on LOW for the recommended time so the center of the pierogi reaches a safe temperature—if your slow cooker runs cool or is very full, allow extra time. Once cooked, hold the pierogi on the WARM setting for up to 2 hours, stirring gently now and then so they don’t stick. Refrigerate leftovers within 2 hours of serving, and reheat thoroughly before eating. If any pierogi smell off or have sat at room temperature too long, it’s safest to discard them. For those watching salt, choose unsalted butter and taste at the end, seasoning only as needed.
